Not just carsWallenius Wilhelmsen transports all types of staticcargo, which by definition includes any cargo that mustbe lifted or towed on board using special trailers. Weare experts in the field of transportation of generalbreak bulk products and other non-containerised cargo,which often require special handling and specialisedsolutions. Wallenius Wilhelmsen takes great pride inproviding both.

Flexible vesselsSmart ocean transport of huge volumes of a wide vari-ety of cargo requires smart vessels. Our vessels aredesigned with specific transport needs in mind andwith the flexibility to accommodate as many differenttypes of cargo as possible. To keep pace with our cus-tomers’ changing needs, we are continually in theprocess of evaluating and updating the design of ourvessels.

Innovative cargo handlingAs cargoes have become less standardised, they havealso become more challenging to transport. We atWallenius Wilhelmsen are committed to accepting thischallenge. If our existing equipment does not meet yourcargo requirements, we ask design engineers to craft asolution. This creative approach to cargo handling iswhy customers with non-standardised cargo require-ments rely on Wallenius Wilhelmsen — time and timeagain.

Transporting staticcargo

Every year, Wallenius Wilhelmsen transports significantvolumes of cargo all around the world. We are perhapsbest known as a leading ocean carrier for the transportof cars — carrying nearly two million vehicles each year.But take the “car” out of cargo and you will discoverthat Wallenius Wilhelmsen transports a whole lot more.

Delivery in perfect conditionQuality is the hallmark of cargo handling at WalleniusWilhelmsen. No matter how unusual the cargo, qualityfor us is synonymous with delivery in perfect condition.

Delivery in perfect condition is a fundamental way ofthinking at Wallenius Wilhelmsen. This is becausecargo care is not only a business imperative, but a wayof life for many of our employees. It is not unusual, forexample, to find a few of us on hand to witness theloading or discharging of an unusual item of cargo —even when duty does not warrant our presence.

Confidence characterises the way in which our cus-tomers entrust Wallenius Wilhelmsen with their cargo.This confidence stems from our zero-tolerance policytowards cargo damage, which is rigorously enforcedthrough the application of best practices and the con-tinual improvement of handling procedures.

Wallenius Wilhelmsen also encourages the “less-pack” concept of minimal cargo packaging, which isbased on the philosophy that the more we can see ofthe cargo, the better we can cater to its special needs.The less-pack concept also has the added benefit ofreducing packaging costs.

Above all, customer satisfaction is the determiningfactor behind Wallenius Wilhelmsen’s cargo handlingpolicies and procedures.

Damage prevention programmeA belief in having the best policy, however, means littleunless this creed is put into practice. Through practicalhands-on procedures, the Wallenius Wilhelmsen dam-age prevention programme ensures excellent quality ofcargo handling and safe, efficient transport. We havesystems in place to measure performance in order tobe in a position to continually improve our operations.

Wallenius Wilhelmsen provides strong operationalsupervision while handling cargo. At all major portsWallenius Wilhelmsen’s staff, together with the vessel’screw, oversee operations to ensure damage-free load-ing and discharging of cargo. This ensures propercargo handling procedures are applied at all times. Inall other ports, the vessel’s crew oversee loading anddischarging operations.

In addition, our customers provide us with feedbackon our performance on a regular basis. We want to bethe first to know about any problems as well as be thefirst to receive acclaim. As a consequence, we have anongoing dialogue with our customers to establish whatimprovements they would like to see.

Wallenius Wilhelmsen also encourages input fromour employees as well as from stevedores and lashingsubcontractors. Because these individuals work on thefront line, they have first-hand experience and knowl-edge of what can go wrong and can make recommen-dations about how to improve handling procedures.

Page 7: Static Cargo

Handling 7

A personal commitment to quality Secure handling can only be guaranteed through theexpert knowledge and dedication of the people whotake care of your cargo. Every individual at WalleniusWilhelmsen, whether working directly with the cargoitself, or having responsibility for its transport from adistance, makes a personal commitment to qualitycargo care.

This commitment is reinforced through continuoustraining and education. Our cargo handling specialistsstay abreast of advances being made in best practicesand apply this knowledge by sharpening their practicalskills under real operational conditions.

Wallenius Wilhelmsen also ensures that any cargohandling knowledge acquired over the years is sharedthroughout the company. Our instructions manualscover everything our personnel need to know abouthandling cargo — from what clothing is required duringloading, lashing and stowage procedures to the super-vision of operations, to safety issues applicable to allareas of the handling process.

The proof of our commitment lies in what we haveaccomplished, which is demonstrated by our soundtrack record for delivery in perfect condition. It is alsoevident in what we set out to do: to continually improvecargo handling procedures.

Continual improvements After analysing cargo handling data and feedback infor-mation from our customers, employees and subcontrac-tors, we at Wallenius Wilhelmsen are then in an idealposition to identify and implement improved handlingpractices throughout the organisation.

All data compiled is made available to WalleniusWilhelmsen staff around the world. This enables us torecognise trends that may help prevent future damageand to determine the root cause of problems shouldthey occur.

To ensure quality, we constantly monitor changes inprocedures, thus guaranteeing that improvements tocargo handling operations are fully realised. If and whenrequired, we refine our handling practices to enhancetechnique and performance.

Longer, taller, heavier…it’s all on its wayAs a global operator, we are able to transport almostany product to almost any destination around the world.The transport of cargo that requires special know-howis an area in which we at Wallenius Wilhelmsen areexperts. Our cargo team looks after a variety of staticcargoes that require special attention throughout thevoyage.

Special cargoes call for vessels that offer a degreeof flexibility. Our vessels are highly adaptable and capa-ble of accommodating a wide variety of cargoes. Inaddition, we develop our own handling procedures andmethods for securing materials to reduce handlingtimes and to minimise risks.

The following is a brief presentation of the wide vari-ety of special considerations applied by WalleniusWilhelmsen when handling static cargo.

Static Cargo 9

Moving cargo across land and sea

Page 10: Static Cargo

Below deck stowage Wallenius Wilhelmsen RoRo vessels can accommodateboats and yachts including cradle as tall as 5.25 m (17ft, 6 in) below deck. This measurement takes into con-sideration the height of a standard rolltrailer and aclearance of 20 cm (8 in) between the top of the cargoand the deck above, which is required for safe opera-tions. Wallenius Wilhelmsen secures cradles to rolltrail-ers by using lashing chains, and then secures the trail-ers with its cargo to the deck of the vessel. Whentransporting a boat or yacht on its own trailer, theheight of the trailer and the roof clearance must betaken into consideration.

On deck stowageAlmost any cargo which exceeds the maximum heightof 5.25 m for stowage below deck can be transportedon the upper deck. Loading directly out of and dis-charging directly into the water is possible with the useof a crane. Large yachts travelling on the weather deckare secured with additional lashing from the hull of theyacht to the deck of the vessel.

Boats and yachtsSailing on board a Wallenius Wilhelmsen vessel is anunusual mode of transport for most yachts, sailing andtrailer boats. However, these boats and yachts will,most likely, never experience a smoother journey.Wallenius Wilhelmsen provides the utmost care andattention to ensure safe and secure ocean transport.

Wallenius Wilhelmsen offers several methods forloading and discharging yachts, sailing and trailerboats. Most often, smaller boats and yachts arrive atthe port of loading on their own trailers and are care-fully towed on board.

In cases where larger boats and yachts reach theport in cradles, Wallenius Wilhelmsen loads both thecradle and its cargo onto a rolltrailer for stowage onboard. At the port of discharge, we can also lift or de-liver boats and yachts directly into the water usingeither a floating crane, a mobile crane or a port crane.

Page 11: Static Cargo

Creative weather deck transportOccupying almost all of the space nearest the stern onthe weather deck is a 33-m-long by 17-m-wide catama-ran. While sailing in the Southern Ocean, its mastbroke and the task of returning the cargo to its homeport in England was entrusted to WalleniusWilhelmsen.

The Operations Director of the U.K.-based specialistfreight forwarder responsible for bringing the catamaranhome is on hand to watch the discharging. This is notthe first time he has relied on Wallenius Wilhelmsen forquality service. “Wallenius Wilhelmsen provides goodservice, otherwise we would not have worked withthem this long or this closely,” he says. “The company isprobably the number one supplier in terms of gettingthe job done right at the right time.”

The massive size of the catamaran does not leavemuch room to manoeuvre. The huge floating crane thathas been called in to lift the catamaran off the deckplaces it gently into the water. Though this catamaran isthe largest boat ever to be shipped on a WalleniusWilhelmsen weather deck, it most definitely will not bethe last. Static Cargo 11

Wallenius Wilhelmsen carries large volumes of machin-ery and machine tools around the world. Often fittedwith sophisticated electronics, these loads requirecareful handling. Consignments can vary from individualmachine tools to full production lines or even whole fac-tories, with sizes and weights that may differ with eachshipment.

Wallenius Wilhelmsen provides strong operationalsupervision while handling this valuable cargo.Supervisors are on hand to ensure delivery in perfectcondition so that the production lines or factories thatrequire this equipment can open on time and withoutany delay.

Wallenius Wilhelmsen encourages shippers to sendcargo using minimal packaging. Apart from a sturdybase, consignments are often just wrapped with plasticsheeting, which enables us to clearly see the cargo forproper handling and stowage. This also reduces thecosts for our customers. Other cargo, such as printingmachines and printing presses, are transported incrates on rolltrailers.

Machinery andmachine tools

Page 13: Static Cargo

HandlingMachinery. The size and weight of the machinery beingshipped determine the type of equipment used to load,stow and discharge the cargo.

Wallenius Wilhelmsen handles most machinery usingstandard rolltrailers that have a gross capacity of up to120 tons. For cargo weighing between 120 and 180tons, Wallenius Wilhelmsen uses its own speciallydesigned Samson heavy lift trailer. WalleniusWilhelmsen utilises jack-up trailers, also known ascometto trailers that are configured to the exact require-ments of the cargo weighing in excess of 180 tons.

For the heaviest cargo, Wallenius Wilhelmsen uses a12-axle jack-up trailer. Towing or trailering cargo onboard eliminates the risk of potential damage that isever present during lift-on/lift-off operations.

Machine tools. Machine tools include any machineryused for cutting, shaping or forming of metal. These in-clude sophisticated production units for the automotiveand aircraft manufacturing industries, some of which arefitted with sophisticated computer units. Any machinetools that come in cases, wooden crates or steel cratesare generally carried on rolltrailers or bolsters.

StowageWallenius Wilhelmsen usually stows cargo on rolltrail-ers, but bolsters are also used for smaller sized cargo.Cargo is securely lashed to the rolltrailers and bolsters,which in turn are secured to the deck of the vessel.Due care and consideration are given to secure cargoto avoid mechanical stress which can cause damage.

Miningequipment

Wallenius Wilhelmsen offers excellent transport solu-tions for mining equipment. We transport large volumesof cargo, either as complete units or as individual com-ponents.

Our vessels which offer a high degree of flexibilityare built to accommodate a wide variety of unwieldy,heavy cargo — from drilling machines and mine roofsupports to conveyor belts and mining constructionequipment. Our RoRo carriers have stern ramps thatare capable of supporting a weight of up to 420 tonsand stern ramp openings that are 12 m wide by 6.4 mhigh.

Wallenius Wilhelmsen encourages shippers to sendcargoes ‘as is’. No additional packaging is required.This enables our cargo handling specialists to clearlysee the cargo and to ensure proper handling andstowage, whilst also reducing costs for the customer.

Page 15: Static Cargo

Static Cargo 15

HandlingWallenius Wilhelmsen handles most mining equipmentusing rolltrailers which have a capacity to handle up to120 tons. For cargo weighing between 120 and 180tons, we use our own specially designed Samsonheavy-lift trailers.

For cargo that exceeds the capacity of our ownequipment, Wallenius Wilhelmsen utilises jack-up trail-ers, also known as cometto trailers, which can be con-figured to the exact requirements of the cargo. Towingor trailering cargo on board eliminates the risk of poten-tial damage during lift-on/lift-off operations.

StowageOn most trade routes, equipment weighing up to 340tons can be stowed below deck. Depending on thetype of cargo, equipment may be securely lashed andstowed on blocks and beams, or alternatively, it mayalso remain on the trailer used to load the equipmentfor the entire duration of the ocean voyage.

Page 16: Static Cargo

Power generation equipment is exceptionally large andheavy cargo. As such, it requires exceptional attentionto detail for secure handling and safe transport.Wallenius Wilhelmsen provides both.

Every day Wallenius Wilhelmsen is involved in trans-porting all types of power generation equipment — from144-ton generators to 305-ton turbines — somewherearound the globe. This experience, in addition to givingus insight into exactly how each type of equipmentshould be handled and stowed, also ensures opera-tions can be run more efficiently.

Then there is always the unexpected challenge. Wehave encountered our fair share and can rely on bothour ingenuity and expertise to come up with innovativetransport solutions. Tackling these challenges is part ofour commitment to delivering your cargo in perfect con-dition, every time.

Power generationequipment

Page 17: Static Cargo

HandlingWallenius Wilhelmsen cargo specialists are on handevery step of the way to ensure proper handling andstowage. Different types of trailers, our own as well asleased, are used to transport the equipment.

Rolltrailers handle cargo, such as generators andpower plant equipment in crates, weighing up to 120tons.

Samson heavy-lift trailers, specially developed byWallenius Wilhelmsen, carry heavier equipment such astransformers that have a gross weight of up to 180tons.

Even heavier loads can be accommodated on 12-axle jack-up trailers, popularly known as cometto trail-ers. These sectional jack-up trailers are configuredaccording to the size and weight of the cargo.

StowageEquipment, such as generators, turbines and transform-ers, are stowed below deck. Wallenius Wilhelmsen isable to stow cargo weighing up to 340 tons belowdeck. Equipment may be stowed and securely lashedon blocks and beams, or alternately, it may also remainon the trailer used to load the equipment for the entireduration of the ocean voyage.

Wallenius Wilhelmsen transports increasing volumes ofwind turbine equipment around the globe. Becauseconstruction and maintenance costs are similar whetherthe turbine is large or small, utility companies are build-ing the largest feasible turbines to gain competitiveadvantage. Our job is simply to deliver.

Whether just-in-time delivery for a new wind farm siteor ongoing transport of replacement parts, WalleniusWilhelmsen is up to the challenge.

Our cargo specialists pay great attention to details —to every aspect of loading, stowage and discharging oftower sections, individual nacelles and hubs or com-plete wind turbines.

For example, we know that blades of all sizes aresusceptible to windage. Therefore when placing bladeson the weather deck, our crane operators exerciseextreme control to ensure proper, incident-free loading.

Wind turbine equipment

Page 19: Static Cargo

Below deck stowageNacelles and hubs. These are usually packed in fibre-glass moulds for protection. Wallenius Wilhelmsen usu-ally loads and transports an 80-ton nacelle and a 10-ton hub together on a 40-foot rolltrailer. Chains securethe cargo onto the rolltrailer, which in turn is lashedwith chains onto the deck of the vessel.

Loose blades with deck supports. Loading windmillblades requires open space for safe and efficient opera-tions, which is why loose blades that are wrapped inplastic are often the first cargo to go on board at theport of loading.

Blades with deck supports are loaded onto 25-mshuttle trailers. Once on board, Wallenius Wilhelmsenuses specially manufactured bottom lifting devices tostow the cargo. Blades are stowed and secured sideby side, turned tip to base, to ensure the most efficientutilisation of space.

Blades in stackable frames. Shippers also deliverpairs of blades in stackable frames with each end ofthe blade secured within the frame. These frames canbe efficiently stacked below deck.

On deck stowageLoose blades with deck supports. Blades that arelonger than 25 m are usually lifted by crane onto andoff the weather deck of the vessel where they rest ondeck supports.

Towers. Wind towers are generally divided into threesections in lengths of approximately 25 m each. Eachsection can weigh anything between 15 and 40 tons.Tower sections are usually handled on rolltrailers andsecured for transport on the weather deck.

Page 20: Static Cargo

Though not an obvious means of transport, a largenumber of railcars are transported each year by sea.Wallenius Wilhelmsen is one of the industry’s leadingrailcar carriers.

Wallenius Wilhelmsen has developed two uniqueconcepts for handling railcars, one for fully assembledrailcars with bogies and one for railcar shells withoutbogies. Rolltrailers, also known as mafi trailers, are alsoused to transport railcars.

Rubber Tyre BogiesWallenius Wilhelmsen carries railcar shells withoutbogies on board our RoRo vessels using Rubber TyreBogies. These are customised to fit the specific railcarmodel to be transported. During typical operations rail-cars are lifted only twice: once onto the Rubber TyreBogies and once off. Once situated on the Rubber TyreBogies, railcars are then towed on board for stowagebelow deck.

Rubber Tyre Bogies are equipped with air brakes forroad use. If road permits have been granted in theexporting country and in the country of destination,Wallenius Wilhelmsen can offer door-to-door delivery ofrailcars. Wallenius Wilhelmsen Rubber Tyre Bogieshave been granted road permits for use in the UnitedStates.

Page 21: Static Cargo

Tight space, tight deadlineHow do you get a 31-m railcar to withstand a muchsteeper climb than it has been built for and then turn itmore or less 90 degrees inside a 32-m-wide vessel?This was the challenge that Wallenius Wilhelmsen wasfaced with in Bremerhaven, Germany.

A special design team quickly created the perfectsolution by simply shortening two rolltrailers and fittingeach with a turntable. These were then placed undereach end of the railcar in a way that relieved the sensi-tive bogie sets from any stress.

Once inside the vessel, the turntables made it possi-ble to swing the railcar with very little radius, contribut-ing to the success of loading and discharging opera-tions.

Air ShuttleThe Air Shuttle trailer is specially designed byWallenius Wilhelmsen for loading and discharging fullyassembled railcars with rail bogies attached.

Fitted with rails on top and a pneumatic system, theAir Shuttle can raise and lower the trailer bed toground level, eliminating the need to lift the cargo.Instead, railcars weighing up to 47.5 tons can be towedfrom rail tracks directly on to the Air Shuttle. Once therailcars are wheeled onto the vessel, the shuttle isremoved and deployed elsewhere, saving time, cuttingcosts and improving the overall quality of service.

GreenhoferGreenhofer is the Air Shuttle’s “little brother” and func-tions very much in the same way. However, theGreenhofer can only transport a maximum weight of upto 15 tons, which makes it ideal for the transport of rail-car shells and light railcars with exposed rail bogies orwith rail bogies in crates.

Wallenius Wilhelmsen transports significant volumes ofnatural rubber. Though not extremely heavy, high orbulky, this sensitive cargo requires special handling pro-cedures.

Through years of practical experience, WalleniusWilhelmsen has learned about the unique characteris-tics of natural rubber, especially its sensitivity to mois-ture. Due to this sensitivity, this type of cargo is alwaysloaded and stored under cover.

Wallenius Wilhelmsen has developed secure han-dling procedures to ensure that natural rubber retainsits key properties and characteristics necessary for theonward manufacture into finished products.

Naturalrubber

Page 23: Static Cargo

Handling and stowageWallenius Wilhelmsen handles consignments of naturalrubber that are packed in steel or wooden crates orshrink-wrapped on wooden pallets, by using trucks orroad trailers to transport the pallets or crates on board.

Small forklifts are then used to lift and stow thecargo. Shrink-wrapped units and wooden crates arecarefully stacked, three high, below deck. Whenstacked three high, shrink-wrapped units may be stag-gered. Strong plywood boards are placed between thelayers to provide extra support. Metal crates may bestacked four high and cardboard is placed betweenthe layers.

Sturdy lashings secure the cargo, and corner protec-tors prevent damage to the edges. To prevent damageto cargo, the dew point is constantly measured belowdeck and proper ventilation facilitates the prevention ofexcess humidity. Static Cargo 23

Page 24: Static Cargo

Whether in sheets, coils and cable reels or as pipesand beams, all types of special steel are transported onboard Wallenius Wilhelmsen vessels. We move largelots of low-grade steel as well as smaller lots of high-grade steel, such as stainless steel, all over the world.To accommodate these heavy loads, our RoRo vesselshave deck strengths on the tank top of up to 10 tonsper square metre.

Wallenius Wilhelmsen is well aware that steel ishighly susceptible to corrosion and therefore we ensurethat this corrosion-sensitive cargo is always loaded anddischarged in dry weather conditions or under cover.

We also know that steel coils are particularly sensi-tive to mechanical damage and to pressure derivedfrom excessive handling and that any distortion is detri-mental to further processing. To prevent damage, wetherefore prefer to load sheets and pipes on bolsters. Steel

Page 25: Static Cargo

HandlingCoils. Depending on their size and weight, coils arehandled with forklifts with special attachments. Forlarge steel coils, we use a forklift attachment fitted witha large rod. Smaller coils are handled with a forklift fit-ted with a suitable piece of pipe threaded onto theprongs.

Sheets. Bolsters or rolltrailers are used to transportstainless steel sheets. To prevent the wavering of thesheets, sufficient interlayer dunnage is placed under-neath each sheet or pack of sheets. Edges and cornersare also protected. Stainless steel is always storedunder cover in the terminal on flat, dry, clean surfaceareas.

Pipes. Small to medium-sized pipes are carried on bol-sters, which may be used for door-to-door transport.Pipes are secured to the bolster with wire or chains ofsufficient strength, and the length of the pipe maysometimes exceed that of the bolster itself.Exceptionally large pipes are generally handled asloose cargo, while smaller pipes may be bundled forhandling by a medium-sized forklift.

StowageDue to its weight, steel is generally stowed in the lowerhold. These holds are protected from weather and sea-water to minimise the risk of corrosion. Smaller volumesmay be stowed under ramps.

Reliable equipment to pull it offLoading, stowing and discharging cargo are delicateoperational procedures that demand both experiencedpersonnel as well as purpose-built equipment. Thelonger, the taller and the heavier the cargo, the greaterthe demands.

Whatever your shipping needs, WalleniusWilhelmsen can supply the equipment necessary toensure that we handle your cargo in the safest andmost efficient manner possible. If the equipment doesnot exist to handle your particular cargo, our designspecialists use their ingenuity to customise a solution.

Our range of well-adapted equipment facilitatesloading and discharging operations. Our equipment isclean, readily accessible and undergoes scheduledmaintenance and inspections. Wallenius Wilhelmsenpersonnel make sure that operations are conductedsafely and without incident in keeping with our zero-tolerance policy.

Here are some examples of the reliable equipmentthat we use to handle your cargo.

Rolltrailers, which are also known as mafi trailers, aredesigned for RoRo transport of large heavy units, butcan also be used for most types of general cargo andcontainers. Rolltrailers are also frequently used fortransporting cargo into and out of the lower decks of avessel, where the cargo is taken off the trailer andstowed loose and secured.

Securing cargoWallenius Wilhelmsen rolltrailers have wooden floorsand rubber mats to provide a non-skid surface. Lashingrings or bars are located on both sides and at the frontand rear of the trailer. Depending on the type of cargo,Wallenius Wilhelmsen uses chains, wires or web lash-ings to secure the cargo to the rolltrailer. Additionallashings from the cargo directly to the deck of the ves-sel are used to secure large and heavy cargo and roll-trailers are secured to the deck with chains.

For longer, shorter or narrower cargoWallenius Wilhelmsen has solutions for heavy cargothat is longer, shorter or narrower than our standardrolltrailers. For longer cargo, rolltrailers can be extendedby adding a bolster that is positioned 3 m (10 ft) fromthe rear end of the rolltrailer and secured by a twistlock. For shorter cargo, steel beams or heavy timbermay be placed length-wise beneath the cargo and ontop of the trailer to distribute the weight. For narrowcargo that is less than 3 m wide, the cargo is placedon steel beams or on heavy timber blocks extendingfrom side beam to side beam.

One of the world’s largest fleetsWallenius Wilhelmsen operates one of the world’slargest fleets of rolltrailers, more than 1,200 in all. It is adiverse fleet ranging in length from 6 to 24.38 m and incapacity from 25 to 120 tons.

Page 30: Static Cargo

Jack-up, or cometto trailers are built to carry exception-ally heavy cargo weighing several hundred tons. A jack-up trailer consists of four-axle sections that can be con-figured to carry cargo of almost any size and weight.The largest configuration is 12 axles long by 8 m wideand rests on 192 wheels.

Before transfer onto a jack-up trailer, the cargo isplaced on beams and support blocks in the terminal.Steel support blocks are required for heavy units thatweigh 120 tons or more. For cargo weighing less than120 tons, heavy timber support blocks may be used.

Cargo specialists use the built-in hydraulic system tolower the trailer into position to take on cargo, carefullyplacing the trailer beneath the cargo. Once in the cor-rect position, the trailer is elevated, carrying the fullweight of the cargo and steel beams. The supportblocks are then removed and the trailer is towed onboard by one or more heavy-duty tow trucks.

Once the trailer is in the correct position on board,support blocks are placed under the beams. The traileris lowered until the full weight of the cargo rests on thesupport blocks. The trailer is then removed and thecargo secured. This operation is reversed at the port ofdischarge.

The Samson heavy-lift trailer is well suited for small andmedium-sized lifts, such as transformers, generatorsand turbines.

Specially designed by Wallenius Wilhelmsen, thisheavy-duty trailer consists of a platform with two-wheelbogies with two axles each. Many of our vessels canaccept a four-axle trailer with a gross weight of 180tons, without exceeding the maximum permissible axleload.

Before loading, cargo is placed on the platform ofthe trailer. The trailer with the cargo is then transportedby two tow tractors to a stowage location on board.Using an electric hydraulic pump which raises the inte-grated hydraulic pistons, the platform is elevated toenable the positioning of heavy timber or steel sup-ports.

Heavy timber or steel blocks are placed under theside beams of the platform, after which the platform isthen lowered so that it rests on the blocks. The bogiescan now be pulled out from underneath the platformand used for the next lift. At the port of discharge theprocedures are reversed.

Wallenius Wilhelmsen has manufactured 12 Samsonheavy-lift trailers: eight 8-m-long flats and four 10-m-long flats. All platforms are 3 m wide. WalleniusWilhelmsen has five sets of bogies with electricallypowered hydraulic pumps.

The Air Shuttle trailer is proof of WalleniusWilhelmsen’s ingenuity at work. Designed by employ-ees in Bremerhaven, these trailers transport fullyassembled railcars or railcar shells with rail bogiesattached. The Air Shuttle eliminates the need to liftheavy assembled railcars, trams and subway cars bycrane onto rolltrailers for transport.

The Greenhofer is a smaller variant of the Air Shuttleand as such, it functions much in the same way.However, because of its lighter construction, theGreenhofer carries a maximum payload of 15 tonswhile the Air Shuttle can carry loads of up to 47.5 tons.

The Air Shuttle and Greenhofer significantly reducethe potential for damage that can result from liftingheavy cargoes that may contain sensitive computerequipment. Railcars simply roll on to and off of the trail-ers. This process saves time, cuts costs and improvesthe overall quality of service provided.

How it worksFitted with rails on top, the Air Shuttle has a pneumaticsystem that can lower the trailer bed to ground level.This enables direct transfer of railcars from rail racks tothe Air Shuttle trailer via a ramp. Railcars can also belifted onto the trailer. Horizontal transfer to or fromanother trailer is also possible. The distance betweenthe frames on which the wheel bogies rest can beadjusted.

The Air Shuttle lifts the railcar and frames off of theframe supports and transports the railcar to a stowagelocation on board. There the trailer is lowered so thatthe frames again rest on the stanchions. The Air Shuttleis now free to load the next railcar. At the port of dis-charge the procedures are then reversed.

Only two Air Shuttles are required for a major con-tract, one located in the port of loading, and one in theport of discharge.

The Rubber Tyre Bogie concept was originally devel-oped for below-deck RoRo service of railcar shellsshipped without bogies attached and equipped with airbrakes.

How it worksEach railcar shell requires two Rubber Tyre Bogies,which together can accommodate a load of approxi-mately 45 tons. Wallenius Wilhelmsen customises thebolsters on top of the Rubber Tyre Bogies according tothe technical specifications of the railcar shell.

The customised bolsters act as the coupling thatconnects the railcar shell to the Rubber Tyre Bogies.The railcar shell is lifted onto and coupled at each endof the car to the Rubber Tyre Bogies. A railcar shell islifted only twice, onto Rubber Tyre Bogies when load-ing and off again when discharging the cargo.

A terminal truck tows the Rubber Tyre Bogies withthe railcar shell on board. For safe manoeuvring, thebolster on the front bogie remains unlocked to facilitateturning while the bolster on the rear bogie is locked.

StowageOnce the railcar shell is on board the vessel, the towtruck is usually disconnected. The rear bolster is thenunlocked. Two small forklifts, one at each end of theshell, manoeuvre the railcar into its final stowage posi-tion. Both bolsters are then locked to hold the shellsecurely in place, eliminating the need for lashing theshell.

Timber stanchion blocks are placed, both fore andaft, under the bolsters on both sides. The Rubber TyreBogies are securely lashed with chains and binders torings that are welded to the deck of the vessel. At theport of discharge, this operation is reversed.

Door-to-door serviceDoor-to-door service can be provided as long as roadpermits for the bogies have been obtained in theexporting country and in the country of destination.Wallenius Wilhelmsen’s Rubber Tyre Bogies have beengranted road permits for use in the United States. Thisenables the delivery of railcar shells on bogies directlyto the factories.

Shippers can pick up Rubber Tyre Bogies from theterminal and transport them to their sites. Shippers canalso transport railcar shells to the Wallenius Wilhelmsenterminal for mounting by our stevedores. After transport,shippers simply return the empty Rubber Tyre Bogiescoupled in pairs to the Wallenius Wilhelmsen terminal.

Wallenius Wilhelmsen currently owns approximately250 Rubber Tyre Bogies.

Bolsters, or flatbeds, are well suited to ensure damage-free handling of heavy, bulky cargo. This includes cargosuch as components, pallets, bales, bundles, reels orcrates. Heavy-duty forklift trucks and trailers move andstow the bolsters.

Cargo on bolsters is always stowed below deck andmay be stacked, depending on the type of cargo. Tosecure the cargo, web lashings or chains are threadedthrough the lashing eyes on all four sides of the bolster.For fragile cargo, Wallenius Wilhelmsen places cornerprotectors under the lashings. Bolsters are secured tothe deck of the vessel.

On request, shippers can collect bolsters for stuff-ing. Empty bolsters are transported in bundles of sixunits per truckload. Consignees can pick up the loadedbolsters at our terminals in the port of discharge fortransport to their warehouses.

Wallenius Wilhelmsen owns approximately 5,000bolsters.
