a natural way for everyone to think and act. A good example of this is the constant progress made by the NINA (“No Injuries, No Accidents”) project, which over the years has brought us signifi -cant positive results in the fi eld of occupational safety.

Assessing the outlook for next year, it can be said, at long last, that Finland’s marine construction market is beginning to recover after a few quiet years and is thereby also reinforcing belief in our business operations in domestic markets. The importance of neighbouring areas will also remain important, so our vessels will also be busy in the Baltic Sea region in the future.

As we enjoy a particularly warm autumn, I would like to thank all of our staff, customers and partners for the past year.

As an encouragement to cooperation, working together and learning, I wish all the readers of this magazine a wonderful spring!

Jarmo Yletyinen MANAGING DIRECTOR, TERRAMARE OY, FINLAND

Finnish companies’ loss of market share during the reces-sion that followed the fi nancial crash of 2008 is often ex-plained by the fact that Finnish exports, in the post-mobile

phone period, focused too narrowly on heavy investment goods for manufacturing industry. Our problem is that demand for these products has not yet recovered to pre-recession levels. Here, too, our dear western neighbour Sweden outshines us with a much wider export base, which is refl ected in clearly higher growth fi gures. The statistics show that during the third quarter of 2015, the Swedish economy grew by 3.9% from the previous year, while we had to settle for around zero. Sweden’s record growth is underlined well by the fact that Germany, often considered the engine room of the European economy, recorded economic growth of 1.7%.

It can be said that many export companies’ potential for success in the global market lies in innovations developed through the joint effort of learning and cooperative personnel. Our parent company Boskalis arranges an annual innovation competition. The best proposal in 2014, from over 70 entries, proved to be a concept based on 3D printers by which submarine reefs are cre-ated using locally dredged material. A pilot project was carried out in Port Hercule, Monaco, where a total of six 2.5- tonne reef elements, printed in Italy, were installed with the assistance of a group of divers. In fact, the project, supported by the Prince Al-bert II Foundation, proved to be a prime example of how “out-of-the-box” thinking can give rise to impressive innovation solutions that balance maritime habitats. The project involved scientists, public authorities and technical experts from various fi elds. The guiding aspect of the participants throughout the project was their passion to create something new, yet consistent with the principles of sustainable development. The activity of the reefs will be monitored by Boskalis over the next two years and the in-formation obtained will be shared with the scientifi c community.

The above example shows very well how, with the assistance of innovations, completely new, commercially viable products can be created in traditional dredging operations. This requires, how-ever, long-term investment in product development, a transparent and open corporate culture, and a cooperation- and learning-based human resources policy. Terramare, in accordance with its operating principles, has successfully introduced, through the efforts of its entire staff, improvement proposals in its present working methods as well as ideas for implementing new innova-tions. The search for innovations happens effectively and natu-rally when it is part of strategic activity, in which case it becomes

Metsä Board, one of Europe’s leading manufacturers of fold-ing boxboard and coated

white fresh forest fi bre linerboard, plans to substantially enhance and expand board production at its Husum mill in Sweden. In line with a new strategy, poorly profi table paper production will be gradually discon-tinued. The company has made an invest-ment of EUR 170 million in modifi cation work at the Husum mill, including a new folding boxboard machine, ordered from Valmet. Production will also be boosted by

harnessing one paper machine fully to the production of coated white fresh forest fi -bre linerboard.

Folding boxboard and coated white fresh forest fi bre linerboard are used, for exam-ple, in consumer and retail packaging, disposable food and catering containers, and the needs of the pharmaceutical indus-try. There is a very wide range of possible uses for these printable and durable board materials.

Peter Lundin, Project Manager of Metsä Board’s Husum mill, believes that the new

NEW STRATEGY IN BOARD PRODUCTION – WORLD MARKET LEADERSHIP THE GOAL

05

strategy will increase the company’s mar-ket.

“There is already a lot of demand for our high-quality and ecological board prod-ucts, so boosting production is the right course to take. In addition to Europe, we have directed our sales towards the world market. The new folding boxboard ma-chine’s production is intended for global exports in general, but particularly for the North American market, where there are strong growth opportunities for our prod-ucts,” explains Lundin.

“Metsä Board’s products are attracting interest due to our excellent competitive-ness, the high-quality of our boards, and our self-suffi cient production. As well as board machines, our Husum mill also has its own pulp and energy production, rail-way and harbour. The synergy between pulp and board production in particular is very effective. In addition to these fac-tors, our geographical location is good; the high-quality raw materials we need are obtainable from close at hand. Close co-operation with Metsä Group also facilitates

the effi cient supply of wood and BCTMP pulp,” adds Lundin.

Expanding the harbour is also part of the plan to boost production at the Husum mill. A new 110-metre section of retaining quay wall will be built at the harbour. The new lo-lo quay and harbour fi eld with ac-cessory fi ttings will be constructed by Ter-ramare Oy.

“The new quay is really needed, because ship traffi c will also increase as production and exports grow. We estimate that our harbour will handle more than 700 cargo ships instead of around 600 at present, so harbour capacity has to be increased,” says Metsä Board’s Hans Bonnedahl, Project Manager responsible for the quay project.

The Husum mill’s production capacity will be on a vast scale. The annual production capacity of the new folding boxboard ma-chine will be around 400,000 tonnes and the capacity of the present linerboard ma-chine is 300,000 tonnes, so total annual production will grow to around 700,000 tonnes.

“Effective cooperation, routines and scheduling will be the key issues in the logistics of raw material imports, board production and cargo traffi c,” concludes Bonnedahl.

Metsä Board’s Husum folding boxboard production will start in January 2016. Pro-duction of coated white fresh forest fi bre linerboard began in 2013. It will replace paper production completely by 2017.

HUSUM’S RETAINING QUAY WALL – WITH INNOVATIONS

0101

Metsä Board’s Husum mill area, on the east coast of Sweden, is like a town snuggled up to a

village. The company’s extensive mill com-plex is the most important employer of the small locality of Husum, which has around 1,650 inhabitants. The mill area is being upgraded at a brisk pace, and the various construction projects under way are provid-ing employment for more than a thousand people.

The board and pulp mill’s modifi cation projects also include an extension of the harbour. Terramare is building in the area a 110-metre long and 40-metre wide re-taining quay wall and adjacent harbour fi eld. The quay will be built for lo-lo (lift-

on – lift-off) vessels, which are loaded and unloaded using cranes.

Terramare’s contract covers environmen-tal and mass transfer dredgings at the Hu-sum quay location, casting of the quay’s reinforced concrete elements, construction of the quay and its coping beams, acces-sory fi ttings and erosion protection slabs, construction of the harbour fi eld and its pip-ing, electricity and surfacing work, and the installation of two 24-metre lighting masts

and their foundations. Work began in July 2015 and the term of the contract runs until the end of May 2016.

INNOVATIONSTerramare-supported development work paved the way for the totally new practices introduced in this project.

“We also developed for the project two operational methods, one of which is the deployment of reusable supports, which

These support tow-ers, properly tested and approved for the installation of basic reinforcement, can now be dismantled and reassembled, so they can also be used in similar projects in the future,” explains Samu Mustonen, Ter-ramare’s Site Manager.

“The second of our innovations is an in-stallation measurement raft, which facili-tates and enhances the alignment of quay elements,” adds Mustonen.

QUALITY CONCRETETerramare began work on the quay project in July 2015 with the casting of the ele-ments’ foundation slabs and the establish-

ment of a slipform casting site. Slipform castings of the quay elements and dredg-ing at the location were launched in Sep-tember and lasted around a month.

“This was a rather exceptional situation time wise, because generally quay work is launched in the early summer. The warm

and windless autumn weather, however, was favourable for the early stages of the project, so we avoided the adverse weath-er conditions typical for that time of year,” says Mustonen.

After the base slabs were produced, all sixteen K elements and fi fteen intermediate

were made using the slipform casting technique at the back

of the quality site.

IN THE LIMITED SITE AREA THE ELEMENTS

were aligned quite far from the shoreline, so a mobile crane

was needed to transfer them.

METSÄ BOARD HUSUM, SWEDEN | 110 + 40 METRE QUAY PROJECT

S elements were made with slipform cast-ing. The K elements are 12.8 metres high and, complete with base slabs, they weigh 200 tonnes. The narrower S elements, which have no base slabs and are installed between the K elements, weigh 70 tonnes.

“In the slipform casting process, the qual-ity of the concrete is a prime importance, and it was a delight for us to discover that the quality of the locally supplied concrete was excellent. A total 1,300 cubic metres of concrete was used in the entire slipform casting process,” says Mustonen.

“Our quay work differed this time from usual because, due to the limited site area, the slipform cast elements had to be aligned further away from the shore. Generally the elements are lifted from the shore using a fl oating crane and installed directly into place. This time, to transfer the elements we also needed a powerful lattice-boom mobile crane, which carried the K elements

to our fl oating crane Nosto-Pekka. The S el-ements positioned between the K elements could be installed directly into place using the mobile crane,” says Mustonen.

CLAY-RICH DREDGINGAlongside the slipform casting, dredg-ing was also done at the location. Before dredging started, the area was protected by a silt screen, which prevents turbid wa-ter passing into the surrounding waters. For the dredging masses, three dumping basins were constructed at a landfi ll loca-

tion on the shore of the mill area. Of these, two were sealed. In one, contaminated sediment from the environmental dredging was dumped; in the other, too wet clay. Dry or dried clay was dumped into the third basin.

In the basin containing too wet clay, a pumping raft was used to pump water that rose to the surface into a discharge ditch through a fi lter system. After this, the dried clay was moved to the fi nal dumping basin for dry clay.

“In total, nearly 40,000 cubic metres of

09The dredging masses of quay site mainly consisted of clay. The dredged material

04

clay was dredged away from the quay site. Of this, wet clay with a dry-matter content of less that 35% clay accounted for 6,000 cubic metres. Material from the environ-mental dredging totalled 2,000 cubic me-tres. After dredging, the section along the future quay line was fi lled with rock waste, deep-compacted and levelled at the foun-dation depth,” says Mustonen.

Mass transfer and deep compaction were implemented at the quay site using Terra-mare’s dredgers, Kahmari 2 and Kuokka-Pekka 2. The loading vessels were George and Hans, both of which have a load ca-pacity of 500 cubic metres. At the dumping basins, Terramare’s biggest pontoon Bolle VIII, which is 70 metres long and 20 me-tres wide, served as the unloading barge. The fl oating crane Nosto-Pekka carried out the levelling of the base of the future quay line.

“The calm and waveless weather was im-portant in the levelling work. In these work stages, the fl oating equipment must remain fairly steady. So the windless weather we had was just perfect for the levelling work,” explains Mustonen.

ELEMENT INSTALLATIONAfter the levelling and bottom-fi ll work, the next stage involved moving into position and installing the massive reinforced con-crete elements. Both a mobile crane and a fl oating crane were used in moving and installing the elements. The cranes worked well together to ensure the smooth instal-lation of the elements. With respect to the installation of the elements, the 150-metre section of retaining quay wall was complet-ed by the beginning of December.“At the same time as the elements were installed, backfi lling also took place. Rock waste of various sizes, a total of 100,000 cubic metres, was used for both the base of the quay area and for backfi ll,” says Mustonen.

After element installation, the contract continues with above-ground work as well as underwater casting of the erosion-protec-tion slab in front of the quay. A period up

to the end of May 2016 has been reserved for harbour fi eld surfacing work and instal-lation of the quay’s accessory fi ttings.

“In the Husum mill area, several projects have been under way simultaneously, of course, and so things have been rather busy around here. Fortunately, we acted fast in relation to accommodation, because it is really hard to fi nd. Nearly 1,400 people are currently working in the area in various modifi cation projects,” adds Mustonen.

“Around 70 people are working on our own contract. We have progressed step by step, and the most challenging work stages from an environmental standpoint are largely behind us. Now we are focus-ing on the underwater casting and surface structures at the quay, which still amounts to a lot work,” concludes Mustonen.

METSÄ FIBRE, ÄÄNEKOSKI | BIOPRODUCT PLANT CHIMNEY – FOUNDATIONS, SLIPFORM CASTING AND STEEL STRUCTURES

Metsä Fibre, which belongs to the Metsä Group, has a major project under way in Äänekos-

ki. The company is building in the area the Finnish forest industry’s largest ever invest-ment, a bioproduct mill valued at over EUR 1.2 billion. On completion, the mill will produce 1.3 million tonnes of pulp per year as well as various other bioproducts, such as tall oil, turpentine and bioelectricity. The pulp, which will be sold mainly to Europe and Asia, will have the effect of increasing

the annual value of Finland’s exports by over EUR 500 million.

The project began in spring 2015, and the intention is for test runs of the mill to start in spring 2017. The mill’s 120-metre high and 12.4-metre diameter chimney

has already become an impressive land-mark of the ambitious project’s site area, which covers 40 hectares. From the top of the chimney, panoramic views open out, similar to those from the restaurant in Tampere’s Näsinneula observation tower,

SLIPFORM-CAST MILL CHIMNEYTerramare built the bioproduct mill’s huge chimney utilising the slipform casting tech-nique. The contract also include the con-struction of the chimney’s massive founda-tion, the work on which was completed in July 2015. Approximately 1,100 cubic metres of concrete was used during the foundation’s building work, which lasted around a month. For the slipform casting of the chimney itself, just over 1,400 cu-bic metres of concrete was used. The im-plementation of the chimney using slipform casting took just under seven weeks. The chimney's steel structures were carried out after slipform casting.

“In the slipform casting of high structures such as chimneys, the key aspect is the way that building materials and equip-ment are transferred to the casting point. For example, in chimneys, different kinds of materials such as concrete reinforcement bars and the concrete mass are typically transferred to the casting point by person-nel and goods elevators particularly to the upper heights, whereas in lower struc-tures transfers are typically handled using cranes,” explains Esa Kunnassaari, Terra-mare’s Project Manager.

The installation of the 12.4-metre dia-meter slipform mould began in July and actual casting started in August. The mould was initially installed so that, as planned, it created a wall thickness of 70 centime-

tres. When the starting reinforcements and installation of the mould had been complet-ed, the project proceeded to the slipform casting work. Reinforcement, concreting and smoothing of the chimney wall took place around the clock as the slipform cast-ing mould was hydraulically raised. The raising of the slipform casting mould was done using hydraulic jacks and steel bars set on top of the foundation. With a skilled slipform team, 3-4 metres of chimney wall was completed per day, all the way to a

height of 120 metres.“After making the mould, we progressed

in the casting work from early August to mid-September at a rate of 15-20 metres per week. The hydraulically-raised slip-form casting mould was narrowed at thin-ning points of the chimney wall so that the 70 centimetre thickness at the bottom of the chimney well was ultimately 25 cm at the top of the wall, after two thinning stages. The inner diameter of the chimney increased at the thinning points while the

anything. In this respect, the upward trans-port of items as well as the casting work present their own risks. Due to this risk fac-tor, it is necessary to have both guard rails above and protective covered walkways below,” emphasises Sukanen.

High-structure slipform casting points are already familiar to Pertti Sukanen from the 1980s. His project experiences include high chimneys, lift shafts, silos and even water towers.

“This nearly 120 metre chimney of Ääne-koski’s is pretty impressive. I have also been involved in a 150 metre chimney project at Vaskiluoto in Vaasa. Other simi-

larly high chimney projects have included, among others, a 146.6 metre chimney at the Pietarsaari paper mill and a 146.3 metre chimney at the Joutseno pulp mill,” recalls Sukanen.

ANATOMY OF A MILL CHIMNEYThe Äänekoski bioproduct mill founda-tion and slipform casting contract includes structures other than the reinforced concrete foundation and chimney structures.

“The slipform casting work completed in September in fact only covers the chimney wall structures. The project continued with the installation of steel structures. These included a spiral staircase that extends inside the chimney from the bottom to the top, a rainwater drainage system and inter-mediate grating levels supported by steel beams. At the top of the chimney, at the uppermost level, a wind chamber has also been installed at the top of the spiral stair-case,” says Project Manager Kunnassaari.

COMPLETED ON SCHEDULEIn large investment projects that have lots of contractors, there is a big emphasis on scheduling. In this project, too, the sched-ule was very closely adhered to. The slip-form casting work of Metsä Group’s bio-

worked progressed. In this way the wall of the chimney was thinned while

maintaining its external diameter.

outer diameter remained unchanged at 12.4 metres from bottom to top,” says Kun-nassaari.

As the chimney and slipform casting mould rose, the personnel and goods el-evators were also raised. In the early me-tres, the concrete mass was transferred directly from the vehicle by crane to the casting point, but later it was also trans-ported upwards by elevator. Terramare’s Site Manager Pertti Sukanen also super-vised site safety alongside the progress of the work.

In the Äänekoski bioproduct mill project, we have advanced from excavation and foun-dation work to the construction of visible elements. Of these, the bioproduct mill’s high and massive chimney, whose slipform casting work was completed in September, is a

fi ne and strong symbol of how things are progressing in the site area as a whole. Our quick-tempo megaproject, which consists of one hundred different projects, will be

implemented using the so-called fast-track method, in which planning and implementation proceed hand in hand. In such an extensive project, scheduling, communication and seamless teamwork are vital factors. With respect to the chimney contract, it should be mentioned that, on my site rounds, it was a delight to observe how well everything was going on the site and how systematically the contract was implemented. Special thanks for this are due to Terramare’s Site Manager Pertti Sukanen, whose conscientiousness both in leading the contract and maintaining site safety were exemplary. Well-deserved praise also goes to the entire chimney contract team for their excellent work from start to fi nish.

Here in Äänekoski, construction will continue precisely according to schedule and plan all the way to 2017. The mild end to the year was favourable for construction, but we are, of course, also well prepared in scheduling terms for the arrival of frost and snow. I hope, however, that we’ll avoid the hardest frosts.

product mill was completed on schedule on 18 September 2015. Terramare's contract was completed on the schedule by the end of January 2016. The chimney project em-ployed more than 40 people, who from now one certainly will not be bothered working at lower heights.

“High chimneys have been rarely built in Finland since the turn of the millennium. It’s great that we have had the opportunity to participate in the Finnish forest industry’s largest project by implementing for our cus-tomer, Metsä Fibre, the bioproduct mill’s foundation, slipform casting and steel struc-tures,” concludes Kunnassaari.

BOSKALIS INNOVATION CHALLENGE – COMPETITION WINNER

UTILISING DREDGING MATERIAL FOR 3D-PRINTED ARTIFICIAL REEFS

Terramare’s parent company Royal Boskalis Westminster N.V. believes that innovation is one of most important catalysts of growth. Therefore, the company has for a long time now

challenged and encouraged its employees to fi nd and develop new creative solutions. In this context, the company organises within the Group the Boskalis Innovation Challenge competition. In 2014 the best submission out of more than 70 competition entries was an amazing idea based on 3-D printing to create submarine reefs.

Environmental Engineer Astrid Kramer and her colleague Senior Engineer Jamie Lescinski realised that dredged materials could be used in the 3D printing of artifi cial reefs, a technique that has been developing rapidly for some time. Artifi cial reefs printed in this way, seeded with corals, among other things, could be composed of materials characteristic to the environment in which they are placed, for example dredged masses from the area itself.

This pioneering realisation has now led to the launch of a pilot project in Port Hercule, Monaco. A total of six artifi cial reefs, com-posed of dredged material and printed in Italy, each weighing 2.5 tonnes, have been installed on the bottom of the sea with the assistance of experts. The project has been funded by the Prince Albert II Foundation, and many scientists, researchers and public authorities are also involved. The artifi cial reefs in the test area will be monitored and studied for two years. If the results are promis-ing, then also in the future some of the dredged material can be utilised to maintain and develop submarine habitats.

15A NEW AND INTERACTIVE SAFETY TOOL

NINA WORKBOX SERIES: SAFE BODY HANDS

Terramare has adopted the NINA workbox series as part of its NINA safety programme. It is a new, practical and inter-active tool that focuses in memorable way on various risk

situations. The fi rst workbox of the series is devoted to attention to hand safe-

ty. The Safe Body: Hands workbox includes various interactive tasks as well as discussion openings on situations where there is a risk of injury to hands. In a task and discussion session lasting around half a day, personnel teams go through various ‘close shave’ and accident situations with the aid of personal experiences. Accidents to hands are common on worksites; nearly one third of Boskalis employees have experienced accidents involving hands.

The objective of the NINA Workbox series is to enhance, using illustrative and memorable examples, safe behaviour and a vigilant mindset. The next workboxes in the series will focus on eyes and feet.
