for the expansion of the harbour at the Husum mills. The Finnish situation is still quite gloomy, but some positive development is, however, evident. In June, we signed a contract with Metsä Fibre Oy for a new chimney for its bioproducts plant being built at Äänekoski. Rising to a height of almost 120 metres, it will become a landmark for the area. Both these contracts for the Metsä Group will employ a large number of our professionals until the end of the year. In June after a seven-year break, we also started contracting in Norway again in a project aimed at deepening the fairway to the Polarbase service harbour at Hammerfest by drilling, blasting and dredging about 130,000 m3 of rock. The working environment and conditions in Ham-merfest at this time of year are exotic as full-capacity work is being done in the 'white nights' of the North. We will tell you more about the Polarbase project in this issue of the maga-zine.
The prospects for the coming years in the Nordic countries and Baltic markets are promising. In our fi eld, some signifi cant fairway and harbour projects are at the planning stage, whose starting times largely depend on permit processing times. Some of these projects have already been under preparation for more than 10 years. The wish list of reforms also contains a government effort to shorten the times needed to process per-mits for investment projects, which is easy to go along with.
I hope you enjoy reading this magazine and I wish all of you a relaxing and safe summer!
Jarmo Yletyinen MANAGING DIRECTOR, TERRAMARE OY, FINLAND
Our new government in Finland has promised to reform many things and to get the wheels of society turn-ing without being held back by needless bureauc-
racy and the jungle of business-related regulations that have been piling up in recent decades. The government has taken a single-minded approach, but it is clear that,as the actual discus-sion of concrete issues begins, dealing with them will not be easy. Many approaches have raised the important question of whether all we Finns are really critically aware of our social situation, and are we ready to play our part in improving the much talked-about Finnish competitiveness. One sign of good community spirit was the negotiation of the moderate wage agreement. This wage agreement at least guarantees one year of industrial peace, during which we can discuss the actual painful points of the strategic government programme.
The effi ciency of collective labour agreements is considered to be one individual thing by which it is hoped that fl exibility can be achieved when negotiating on future pay settlements. The other day, Mika Sillanpää, Executive Vice President, UPM Plywood wrote in the Talouselämä magazine that some of the collective labour agreement regulations concerning continu-ous three-shift work stiffens up company operations and makes it diffi cult to react to both fl uctuations in demand and to the changing needs of clients. Some conditions, such as extra la-bour costs for continuous three-shift work, destroy companies' international competitiveness and thus economically encum-ber the whole of society. It is interesting that the history of additional costs for weekend work is based on the idea that working at weekends is somehow exceptional. This is true in many professions, but has never been the case in continuous shift work. Working shifts fall on a weekend and days off on weekdays for each employee on a regular basis. Sillanpää emphasises that, in strongly developing and forward-moving economies, weekend work is a very normal part of working life. A signifi cant part of the costs of continuous three-shift work results not only from statutory weekend compensation but also from shorter working hours than in competing countries. In comparison, an employee in Finland has 12 more days of paid holiday per year than one in Germany and 24 days more than employee in Estonia.
This is one example of what kind of medicine industry would have to take in order to achieve better competitiveness. Every-one understands that negotiations require not only crisis aware-ness but also an open and unbiased approach from all parties in order to create an objective atmosphere for discussion be-tween employers and employees.
From Terramare's point of view, the current year remains chal-lenging, although in marine construction we are gradually starting to recover from last year's steep fall. Our work situation in Sweden continues to be good. A sign of that is the contract signed at the beginning of June with Metsä Board Sverige AB

CUSTOMER NEWS | KYSTVERKET PROJECT MANAGER VICTORIA WINDSTAD:

Hammerfest, a coastal town lo-cated in Northern Norway, is one of the world's northernmost
towns. You can enjoy white nights and midnight sun in these regions for more than two months starting from May until the end of July. That's why at the Terramare construction site at the Polarbase AS logis-tics centre harbour, the fairway deepening
and widening work can be carried out in round-the-clock daylight.
Polarbase's harbour focuses on service and installation traffi c for the Arctic gas and oil fi elds situated in the Barents Sea. The larger cargo vessels arrive at this har-bour, where cargo is in turn unloaded and loaded into smaller service vessels. The harbour's relatively narrow entrance
channel is currently being deepened and widened. This will enable larger cargo ves-sels to use the harbour, and at the same time the safety and effi ciency of the chan-nel will be improved. A challenge of the channel is the tidal water, where the strong current causes navigation diffi culties in the previously narrow channel.
The client for the Polarbase harbour fair-way project is Kystverket, which is respon-sible for local navigation administration in Norway. Victoria Windstad, Project Manager at Kystverket, is satisfi ed with the speedy progress of the project.
– I've been very content with the progress of the Polarbase harbour fairway project, and I'm also happy about the effi cient on-site communication, which I consider to be especially valuable, says Windstad.
A COASTLINE STRETCHING AROUND THE GLOBE 2½ TIMES
Norway's wonderful and, in places, rug-ged coastline is very winding. According to the latest measurements, the Norwe-gian coastline, including thousands of is-lands and islets, is 103,000 km long. As a

straight line, it would go 2½ times around the globe! This is quite a lot when you con-sider that the length of Norway from north to south is less than 1,800 km.
– Our coastline is very exceptional and its maritime conditions are also more chal-lenging in comparison to sheltered sea. The fl uctuation of the tides in particular and the powerful currents set their own conditions both for sea traffi c and for mari-time construction, says Windstad.
Norway's coastline has a total of about 20,000 km of channels and fairways. Sea traffi c has been strongly increasing for many different reasons. One reason is the challenging and expensive repair construc-tion of the roads, tunnels and bridges that wind their way through the mountains.
– In Norway, we are increasingly trying to transfer freight away from landbased transport onto ships, especially when it is being carried from south to north, says Windstad.
A SEABED MAINLY OF HARD ROCKNear to the coast of Norway underwater drilling and blasting are almost always re-quired in order to make fairways larger as the seabed is mainly consisting of rock.
– Kystverket once had its own marine con-struction unit, which was mainly responsi-ble for implementing fairway projects. Now, however, this has been sold, and the projects are put out to tender. A special feature, however, is that in all projects re-quiring underwater drilling and blasting, a responsible person conversant with and qualifi ed in Norwegian legislation must be involved, says Windstad.
Kystverket takes care of fairway projects centrally. The department both plans projects that have been ordered and pre-pares tender documents for the Norwe-gian regional administrations, which ulti-mately organise the bidding competitions and contractor evaluation themselves. Kys-tverket also monitors the progress of the projects.

POLARBASE AS'S SERVICE AND EQUIPMENT HARBOUR
in Hammerfest has been built on natural spits of land and
islets. The harbour is being further expanded as growth pros-
pects in the region's Arctic gas and oil fi elds are promising.
THE DEEPENING AND WIDENING OF POLARBASE AS's
harbour fairway will allow access to larger vessels. A larger
entrance channel also eases the challenges caused by the tide.
KYSTVERKET'S PROJECT MANAGER, VICTORIA WINDSTAD,
is hoping for more active exchange of opinions than at present
between the Nordic bodies responsible for shipping.

– We at Kystverket employ a total of ten project managers and three supervisors, each of whom is responsible for their own area, even though in effi cient co-operation with each other. In such a divided yet cen-tralised operating model, people can get a good overall picture of what is happening along our coastline, says Windstad.
Although the Norwegian coastline is a challenging environment for fairway projects, Victoria Windstad sees its posi-tive side.
– The challenging working environment and demands set by the growth in sea traf-fi c have shown that necessity is the mother of all inventions. By that, I mean that a so-lution can always be found in the end to a problematic situation, and this is what makes the work very interesting, she says.
Sea traffi c that is also increasing interna-
tionally is creating pressure on ever closer co-operation between the maritime admin-istrations of different countries. Victoria Windstad agrees on this point.
– I would like more active co-operation, for example between the Nordic bodies responsible for navigation, particularly with regard to sharing opinions. I believe that such a forum would generate many good ideas in the further development of shipping, says Windstad.
The project manager, who is really moti-vated by her work, does not hesitate when the conversation turns to a guiding princi-ple and motto that inspires her.
– Do unto others as you would have them do unto you! Valuing the contribution of everyone, be it in mutual understanding or interactive communication, gives a high-quality outcome, she says.
TERRAMARE FAR IN THE NORTHWhen Terramare arrived at Hammerfest at the beginning of June with its vessels, at the same time the company made history. In a successful transportation operation, the vessels were towed about 1,800 nauti-cal miles or 3,300 km.
– Terramare s vessels have of course been transported all the way to the Mediterra-nean and Iceland, but then it was loaded on board ship. This time, the vessels were towed the longest distance that Terramare has ever towed anything, says Reijo Kultalahti, Terramare's Site Manager.
The towed vessels comprised the Play-mate drill platform, Attila backhoe dredger and the 500 m3 barges, SCG 4 and 5. The measurements for the project were done by the survey vessel Luoti.
– The voyage lasted more than 20 days

in quite windy and exceptionally poor con-ditions. Despite the tough voyage, dam-age was avoided and just a few fender tyres fell off, that's all, says Kultalahti.
DRILLING AND BLASTING IN THE TIDAL FLOWTerramare is deepening and widening the entrance channel to the Polarbase service harbour. In the project, a total of 130,000 m3 of underwater rock is being blasted and dredged over a length of 335 metres and a width of 160 metres, with a working depth of −17.3 metres at best. In barge cu-bic metres, the volume of dredging will be about 200,000 m3. The dredged rock is sorted into shore structures for the expand-ing harbour.
– In the tidal fl uctuations, the difference between high and low tides here is three metres, so the currents are very strong. This affects both the charging work and the dredging, but we have learned to get along with this natural phenomenon, which occurs at regular intervals, says Kultalahti.
Although the tide sets its own limits in this project, drilling and blasting can, however, be carried out around the clock.
– From a point of view of the progress of the work, it is very positive that there is no human settlement in the site's vicinity. Because of this, we can drill and blast rock 24/7. What's more, the sun shines during the night and day so visibility is excellent. But although the natural conditions are ex-ceptional with rough scenery compared to our own coastline, it is still a question of traditional underwater drilling and blast-ing work and the dredging of rocks, says Kultalahti.
The contract will last for 12 weeks and employ about 30 Terramare employees. Polarbase AS is constantly developing its harbour, as both gas and oil prospects in the Arctic region look promising. Gas and oil operations have improved Hammer-fest's economic situation and expectations for a better tomorrow are high.

Over time, Terramare's Plant De-partment has developed into an exceptionally versatile repair
and planning centre. It is not only taking care of service and maintenance for ma-rine construction plant, but also moderniz-ing and improving the plant to be more ef-fi cient and safer. New and old technology are put together and thus completely new solutions are invented.Timo Soikkeli, Plant Manager in
charge of the Plant Department, has been working for Terramare for a long time.
That’s why he alongside the other person-nel at Plant Department knows the techni-cal secrets of Terramare vessels like the back of his hand.
– Terramare has more than 30 fl oating marine construction units, each of which having its own unique characteristics. Be-cause of that, each working day brings plenty of new challenges and technical in-novations. There are no similar days at the Plant Department. Many of us have been working here for an exceptionally long time, which probably shows that we quite
like the work, says Soikkeli with a smile. The Plant Department employs a total of
15 professionals in the machine shop, in planning and in supervision. In addition to them, vessel personnel also visit the Plant Department to service and repair vessels.
ITS OWN HARBOUR IN VALKOThe Plant Department is located in Valko at the Port of Loviisa. It has its own area of land covering 2.5 hectares in the southern part of the port. There are a machine shop, warehouses, storage fi elds and quays,

among other things in this area. In addi-tion to the actual repair shop area, there is also the Plant Department Offi ce, which in-cludes facilities for management, planning and staff rooms.
– We moved here to Valko in 2007. Be-fore that, we were based at Masala in Kirk-konummi, which is not on the coast. The relocation of the department to Valko with its good sea connections boosted our op-erations considerably. We can now bring vessels directly in for repair or berthing in our own harbour, or we can renovate and build them on site. We also have docking facilities in Turku and Malmö at our dis-posal, so there is no need to sail all return-ing vessels from work sites to Valko, says Soikkeli.
SELF-SUFFICIENT OPERATIONSTerramare's marine construction equipment is very versatile. It includes many dredg-ers, self-propelled and towable barges, drilling and work pontoons, piling units, fl oating cranes, tugs and also land-based equipment.
– From the very beginning Terramare has had a fi ne tradition of owning, designing and maintaining its own plant and equip-ment. Such self-suffi ciency has been a strong competitive advantage, as we can take care of the reliability and develop-ment work of our units ourselves. It also guarantees effi cient time management for implementing projects, servicing and dif-ferent measures, says Soikkeli.
Repair and servicing operations include direct damage repairs, conversions and scheduled maintenance, inspections re-lated to statutory checks and their related measures.
– Depending on the vessel type, the hull inspections on our equipment are done at 2.5 – 5-year intervals. We inspect the hulls of our vessels for example at Turku Repair Yard, where we get to study the condition of the vessels' underwater hull components >

and equipment. In the annual inspections, we check the vessels' control equipment, radios and fi ttings as well as safety-related matters, explains Soikkeli.
EFFICIENT COMMUNICATION SUPPORTING THE PROJECTSTerramare's heavy marine construction fl eet operates at construction sites in very challenging conditions. Sea winds, waves, currents, moisture, in cold seasons ice and in places also tidal waters subject vessels to severe stress. In these conditions, it must also be possible to carry out servicing on site.
– At construction sites, the project person-
nel of the vessels are responsible for servic-ing. Reliable management of equipment is based on the training of the project per-sonnel, effi cient communication and clear reporting. It is important for all key person-nel both in the Plant Department and at the work sites to be in close co-operation whenever needs for servicing or repair arise. From precise reporting, we also get valuable information for vessel develop-ment work, says Soikkeli.
INNOVATION AND DEVELOPMENT WORKTerramare's Plant Department designs and develops its fl eet with a sense of purpose.
Some older vessels have gone through modernisation process and today their technology is matching the new ones.
– Vessel modernisation is not necessarily our main objective, but updating perform-ance, reliability and safety are. On the other hand, we want to apply to our ves-sels absolutely all relevant modern technol-ogy that boosts competitiveness, empha-sises Soikkeli.
At scheduled intervals, some vessels may also require more extensive modifi ca-tion and repair work. Such investment was made in, for example, a modifi cation to the Playmate drill platform, in which the platform and spuds were strengthened,

and the hydraulics, electrics and pile winches were renovated. Now the vessel can operate not only in underwater drilling and blasting work but also as a base for heavy duty cranes. The latest investments also include the renewal of the crane of grab dredger Meri-Pekka, after which it will also be able to operate as a piling unit or crane. The latest investment is the pro-curement of two 660 m3 self-propelled split hopper barges Terra 1 and Terra 2, and their modifi cation for demanding trans-ports of dredged materials.
– For our vessels we also carry out project-specifi c planning and modifi cation work, in which we strengthen or modify the structure of a vessel's equipment to better suit the particular project, for example if specifi c dredging works are exceptionally challenging or when additional features are required of a vessel, say in the installa-tion of offshore wind farms, says Soikkeli.
SCHEDULING AS A KEY FACTORWhen it is a question of dozens of differ-ent vessels, their maintenance, inspections and transfers to and removals from work sites must be precisely coordinated.
– The scheduling of such a set of fl eet is a job in itself. Everything must be prepared for and faultless and direct communication also plays a key role. It is important that

a vessel being moved away from a work site is in perfect working order again for the next project. When staying on sched-ule, the weather and winter ice must also be taken into account. The latter must also be taken into account in our own harbour, says Soikkeli, glancing at the sunny sum-mer sky.
– But fortunately there's still plenty of time until the winter ice. Summer is the best sea-son for marine constructors, he says.

S chweden Splitt AB quarries and crushes high-quality pale grey granite gneiss on the coast of Southern Sweden. The quarry is located at Elleholm in the municipality of Karl-
shamn. Granite-Gneiss is used widely as a stone for construction. There is great demand for it, especially on the south coast of the Baltic Sea where similar types of stone cannot be found. Granite-Gneiss is exported for example to Denmark, Germany, Poland, Russia and the Baltic states.
Elleholm quarry is located in the ideal position in relation to its target countries and the fairways. Previously, the blasted rock was transported about 10 km to the port of Karlshamn, but in 2013 the company was granted an environmental permit to renovate the old quarry harbour and fairway. The harbour, which has been renovat-ed and expanded for this summer, is located just 500 metres from the quarry, thus signifi cantly boosting production and logistics.
The curved harbour fi eld profi le was preserved in renovation project and due to that the blasted rock conveyor is able to load 110-metre cargo vessels completely. The harbour fi eld structures and the retaining wall as well as the pier were rebuilt. The ship berth was expanded with two dolphins equipped with steel bridg-
es. The jetty located between the steel bridges reaching from the shore to the level of the dolphins was also renovated.
Terramare began the renovation work on the harbour and fair-way in late 2014 with underwater drilling, blasting and dredging. Samu Mustonen, the supevisor in charge for the dredging, con-sidered that project was compact but diverse.
– Although the project involved just construction of a quay with one berth, in terms of work stages it, however, included every-thing that needs to be done on a major harbour project. A special feature of the project was its proximity to nature, as the quarry is surrounded by a conservation area, says Mustonen.
Before the dredging work, the site was isolated with a 250-metre long silt screen, which prevented the turbid water from spreading

into the surrounding waters. Backhoe dredger Kuokka-Pekka 2 was busy dredging a total of about 40,000 m3 of mainly silt and sand from the harbour and turning basins and partly from the fairway. Self-propelled barges Erik and Fredrik transported dredged materi-als to the old berth for dumping and onward to the quarry area where they were encapsulated in the soil. Drilling platform Rock-buster was responsible for the underwater drilling and blasting.
The construction of the quays, dolphins, harbour fi eld and deck elements was started in February 2015 after the dredging was completed. Site Manager Markku Sollo was pleased with the natural surroundings and the resultant peaceful site area.
– It's rare that you get to carry out quay projects in such a peace-ful area in the bosom of nature. One of our operators saw a dol-phin swimming nearby! The weather was favourable too, so the work proceeded fl uently, says Sollo contentedly.
The construction of the retaining wall, jetty and dolphins included bored piling work, forming, reinforcement and concrete casting. The retaining wall was anchored in the bedrock, after which back-fi lling was carried out and the top layers of the apron and yard of the harbour were built. The bored piling work for the jetty and two fi ve-metre wide dolphins included a total of 17 tubular steel piles. The piles were 320 mm in diameter with the lengths up to 18 metres.
– The project was nice to start because the client had already removed the old quay structures. Because of that, we were able to begin the work from a clean slate, says Mustonen.
The jetty, apron, yard and dolphins were easily completed by May within the agreed schedule. In the last work stage, the red steel access bridges leading to the dolphins were installed. The access bridges were made by Botnia-Korro Oy from Ilmajoki. The fi nal things to be fi tted were the quay and dolphin equipment, i.e the bollards, fenders and rescue ladders.
The quarry harbour which has been christened Daniel Holm is al-ready starting its operations this summer. Vessels up to 110 metres long and with a draught of 5.5 metres can now use the harbour.
