MANAGING DIRECTOR'S COLUMN WORKING TOGETHER IS OUR ASSET 03 Year 27 had particular significance for Finland, as we celebrated the 100th anniversary of our country s independence. We have built our country through many stages, independently, and have decided matters together. Together, indeed, was the official theme of our country for the centenary year. Our anniversary was accordingly celebrated by Finns and friends of Finland together. The theme Together is also well suited to Boskalis Terramare s operations and the close cooperation that we have enjoyed with clients and partners in the Nordic countries, the Baltic countries and all the way to India. This year, a special theme in Boskalis Terramare has been the tightening of cooperation within the Boskalis Group. At our work sites, we have made wider use of knowledge and an extended supplier network, which has brought to our sites new international operators. Concrete examples of good cooperation with clients and new partners include a number of quay and dredging projects under way at Finnish ports, and most recently the major quay project in Norvik, Sweden, which will serve the rapid growth of the Stockholm region and the freight transport required by it. In addition, we are implementing an underwater drilling and blasting contract with an international team off the Jawaharlal Nehru Port in India. I have now been in Boskalis Terramare s service for just over a year, and since July 27 the company s Managing Director. In a very short time, I have seen that we have a high level of expertise within our com- pany: experienced marine construction engineers and linguistically skilled and eager-to-learn young staff. This creates a good foundation for developing our company s operations in a technically demanding and international working environment. In marine construction, technical expertise is the foundation of everything, but it alone is not enough, however. In a multicultural and increasingly international working environment, it is important to listen carefully to the ideas of partners, to be able to combine various working methods in a controlled way and, in particular, to promote occupational health and safety. We are making a big effort in Boskalis Terramare to adapt to different cultures, and I believe that this approach is also embraced by clients and planners. Everyone working in the marine construction sector is fascinated by what the sector will look like in the near future. Well, it will look pretty good. After a few quiet years, Finland s industry and trade are picking up. Transport of goods and materials is also growing. In addition, LNG terminal and gas network investments in the Baltic Sea region are stimulating marine construction. In this regard, we already know about the Finnish investments in the Kokkola, Oulu and Vuosaari fairways and ports as well as the Balticconnector gas pipeline link between Finland and Estonia. In addition, many other important projects are in the process of being launched along the Finnish coastline and archipelago. In its bold and proactive style, Sweden has been actively investing for a while now, which has provided work for marine construction companies for a number of years, particularly in the Gothenburg and Stockholm regions. We marine construction operators have a big responsibility to fl y the fl ag of the sector high, develop our own operations and together create opportunities that are attractive and profitable for all parties, when euros or kronor are invested. It seems to me, at least, that 27 passed very quickly. Every day I learned something new and it was a pleasure to get to know you marine construction professionals. Wishing you a successful start to 28 Hannu Tomperi MANAGING DIRECTOR TERRAMARE OY Boskalis Area Nordic -team is introducing the new and international Way of Working (WoW) quality system.

04 PORT OF HELSINKI, FINLAND CRUISE SHIP QUAY AT HERNESAARI (LHD), WEST HARBOUR, HELSINKI HERNESAARI CRUISE SHIP QUAY AN IMPRESSIVE PROJECT TEXT AND PHOTOS: MARKKU SALONEN, PHOTOS 03, 04: V2B, PHOTO 8: PORT OF HELSINKI Terramare Oy is building the new 313 metre long cruise ship quay ordered by the Port of Helsinki. The quay is being constructed at the southern tip of Hernesaari next to Helsinki s West Harbour. The diverse contract has been preceded by a massive 350 metres long and 35 metre wide (upper surface) marine-fill backing embankment, which was implemented for the quay in 26 and for which a total of 320,000 m 3 of blasted rock was used. The preconstruction implemented by Terramare and ordered by the Helsinki Public Works Department at that time also included, among other things, environmental and mass-transfer dredgings at the site and the filling and levelling of a foundation embankment. MASSIVE QUAY WALL ELEMENTS The Hernesaari quay contract, which began in spring 27, was launched in impressive fashion. It was then that the slipform casting of the massive quay wall elements began on top of the backing embankment. After the completion of the base slabs and extensive reinforcement work, dozens of over 13 metre high reinforced concrete elements began to be installed side by side on the embankment as slipform casting progressed. This provided an impressive spectacle for boating enthusiasts as well as the passengers of cruise PROJECT KEY FIGURES Quay length 313 m Quay depth 12,54 m Quay height (from 0-level) 2,8 m Quay wall elements 69 Element height 13 m Total length 345 m K-elements 35 K-element weight / pcs 230 t S-elements 34 S-element weight / pcs 90 t Steel, total 820 t Concrete, total 4 000 m 3 ships visiting the West Harbour. Terramare s Site Manager and experienced slipform casting professional, Pertti Sukanen, has been very satisfied with the progress and quality of the work. We built a total of 69 massive quay wall elements, implemented by slipform casting. Of these, 35 were 230-tonne K- elements, and 34 were the 90-tonne S-el- 02

In all, 820 tonnes of steel and concrete were used for the reinforcement, a total of 4,000 m 3. The slipform casting surface was once again really high quality, for which thanks are due to the whole working team, says Sukanen. The total length of the slipform-cast elements was 345 metres. Some 313 metres of this was used for the actual quay section. The remainder of the elements were installed at the end of the quay and in the structure connecting the new quay to the old one. A total of fourteen 600 mm diameter interlocking bored piles, of which the longest was 18 metres, were also installed in the connecting structure. After the boring, the piles were shortened at their upper ends by 2-3 metres. The connecting structure is anchored by three Gewi bars into a storm bollard foundation constructed in conjunction with it, adds Sukanen. 02 SITE DURING THE INSTALLATION OF THE QUAY WALL elements.

PICTURED, FROM THE LEFT, SITE MANAGER Pertti Sukanen and Project Manager Jani Vyyryläinen presenting the site to a Boskalis Group visitor, Frank Hout. 03 GIANT FLOATING CRANE This time, a more powerful fl oating crane than Terramare s Nosto-Pekka was needed for lifting and moving the massive quay wall elements. Such a crane was found in Poland. The Maja fl oating crane of the company Polskie Ratownictwo Okretowe was highly suited to this challenging work stage. The crane, with its 330-tonne lifting capacity, is remarkable in its dimensions. With this 55 metres long and 25 metres wide self-propelled fl oating crane, the moving and lifting of elements from the backing embankment to the levelled quay line on the seabed proceeded efficiently. The alignment of the elements into position was implemented through the seamless cooperation of survey personnel who worked on the shore, the installation team on the sea, and a construction diver who worked under the water. The elements were lowered into sea to the foundation embankment levelled to 12.54 metres, so a diver was also needed to detach the lifting equipment from the lifting holes in the > 03 04 THE QUAY WALL ELEMENT SLIPFORM CASTING SITE was established in an earlier contract on a blasted rock filled area implemented in the sea.

After completing the backfill work, we will start installing the quay coping beam and superstructure in the spring. When it is finished, the quay will stand 2.8 metres above sea level, says Sukanen. IMPLEMENTED FROM START TO FINISH The Hernesaari quay project, intended for over 300 metre long cruise ships, will continue until October 28. Terramare s diverse and comprehensive contract not only includes the quay wall elements and backfill work but also construction of the quay coping beam, the adjacent harbour field, equipped with public utility services, and the superstructure. In front of the quay wall elements, an erosion slab was cast to the sea bottom to combat the erosion impact of cruise ship propellers. The quay will be delivered fully equipped, including fenders, bollards, protective beans, edge barriers and ladders.

Terramare s Site Manager Arto Kontio says that the parallel implementation of the two contracts is well suited to the progress of work at the site in terms of both operational efficiency and synergy. The completely steel-structured snow dumping quay will be executed as dry work onshore. After completion, the temporary blasted rock filled on the sea side of the quay will be removed and, after finishing work, the quay will be ready to use. 05 THE FLOATING CRANE MAJA, WHICH HAS A 330-TONNE LIFTING capacity, is seen lifting K-elements from the backing embankment. 06 A TOTAL OF 69 QUAY WALL ELEMENTS WERE TRANSFERRED AND lowered into the sea, on to a foundation embankment levelled to -12.54 metres. 07 OFFSHORE INSTALLATION PERSONNEL IN GOOD SPIRITS.

07 TEXT AND PHOTO: MARKKU SALONEN CUSTOMER S NEWS PORT OF HELSINKI, FINLAND PASSENGER TRAFFIC REACHES WORLD S HIGHEST LEVELS IN 27, HELSINKI ROSE TO BECOME THE BUSIEST PASSENGER PORT IN EUROPE, AND POSSIBLY EVEN THE ENTIRE WORLD. Passenger traffic at the Port of Helsinki has been growing steadily for a long time, and last year it reached a record 12.3 million passengers. We have now reached a situation where we have overtaken in passenger numbers Europe s busiest international passenger port, Dover, by around 60,000 passengers. Elsewhere in the world, such as in New Zealand, for example, there are very busy passenger ports, but it s quite possible that they haven t reached these kinds of numbers, says the Port of Helsinki's Technical Director, Timo Laitinen. Alongside visits by international cruise ships, the still busy traffic between Helsinki and Estonia is contributing to the ever-increasing passenger numbers. The Port of Helsinki s West Harbour and its passenger and vehicle ferry transport modernisations have responded well to the growing demand. The harbour investments made at the West Terminals located in Helsinki s West Harbour, and particularly the new West Terminal 2, are mostly completed. We are currently implementing the new cruise ship quay at the tip of Hernesaari, situated next to the harbour. This will replace the present Melkki quay, which will be withdrawn from service to make way for a bridge to be built across the current harbour basin as well as a new residential area. The new cruise ship quay at Hernesaari will therefore not increase the number of ship berths, but on completion it will be able to accept large cruse ships up to 330 metres in length, explains Laitinen. We have also extended the fairway to the east of Pihlajasaari island, located off Hernesaari, and this will also improve access to the large luxury cruise ship, adds Laitinen. The Port of Helsinki s Head of Section, Veikko Saukkonen, the cruise ship quay s project manager, has followed the progress of the project with confidence. The Hernesaari quay contract is an excellent beginning to all of the other positive changes that in the future will transform the environment of Hernesaari into an impressive sight, says Saukkonen. On this, Laitinen agrees with Saukkonen and wishes to send his greetings to all of the Terramare experts implementing the Hernesaari quay contract. Of course, many contracts have their challenging moments, but I have to say that this contract is being implemented by Terramare s professional staff, at least to date, in a high quality, fl awless way. Everyone s maintaining focus, the project s progressing, and that is excellent, concludes Technical Director Laitinen. PORT OF HELSINKI TECHNICAL DIRECTOR Timo Laitinen (right) and Head of Section Veikko Saukkonen have been satisfied with the steady growth in passenger traffic.

08 TERRAMARE IN DISTANT LANDS JAWAHARLAL NEHRU PORT, INDIA UNDERWATER DRILLING AND BLASTING IN THE HEAT OF INDIA TEXT: MARKKU SALONEN, PHOTOS: TERRAMARE OY, PHOTO 4: JNPT INDIA Jawaharlal Nehru Port Terramare is participating as a subcontractor in a major fairway project, in which the fairway of the Ports of Mumbai and Jawaharlal Nehru, located on the west coast of India, is being deepened and widened. Terramare is responsible for the underwater drilling and blasting of the fairway off Jawaharlal Nehru Port. The fairway project itself is being implemented by a consortium formed by Boskalis Smit India and Jan De Nul Dredging India. Terramare will implement the contract in cooperation with the UK company Rock Fall, whose General Manager is Colin Fergusson. In this JNPT-contract Project Managers are Tristan Forsythe and Michael Seckington. The client, India s largest container port, Jawaharlal Nehru Port, is extending and deepening the fairway to accommodate larger cargo vessels. The major dredging project involves deepening and extending the fairway along a section of approximately 35 kilometres. More than 40 million cubic metres of sand, silt, clay and rock will be dredged at the site. The underwater drilling and blasting work includes the removal of 27,000 m 3 of rock waste from an area of approximately 39,000 m 2. The fairway area extended by the drilling and blasting will be deepened to 14.7 metres. Terramare's drilling towers, which were shipped from the Port of Valko to India in the early autumn, are being used at the drilling and blasting site. A total of six drilling towers were refurbished by the international project organisation at the Loviisa equipment centre. The towers were loaded in Helsinki in mid-september and they arrived in India around one month later in October. At the Port of Mumbai, the towers were installed on a barge leased from a local company, explains Terramare s Plant Manager, Timo Soikkeli. The Group is investing heavily in international underwater drilling and blasting, because our market area for underwater BOSKALIS AREA NORDIC S OPERATING PRINCIPLES ARE: WE DO WHAT WE PROMISE RIGHT FIRST TIME WORKING TOGETHER

THE PORT IS EXTENDING ITS FAIRWAY TO ACCOMMODATE LARGER VESSELS. FOR TERRAMARE, THE CONTRACT RELATED TO THE PROJECT REPRESENTS AN OPENING TO THE GLOBAL BUSINESS OF UNDERWATER DRILLING AND BLASTING. 09 drilling and blasting will be extended worldwide in the future, emphasises Soikkeli. The drilling and blasting project, which will last around two months, will employ 25 professionals from Finland, the UK and Portugal. For Terramare s Project Engineer, Tatu Luuri, the project in question is his first work posting to a distant foreign location. I have experience, of course, of international operations through my work with our parent company Boskalis in the Netherlands, but this is my first time working such a distance from home. Here I ve had to get used to quite hot conditions, because the temperature during the day is around +35 C and at night +25 C, says Luuri. The traffic and general practices differ quite a lot from the more peaceful conditions back home, but overall we have a very friendly team here. And because we are far away from the tourist sites, our Nordic appearance arouses some attention here, says Luuri with a smile. Terramare s preparatory work was completed in the latter part of 27. Underwater drilling and blasting began in December. The preparatory measures kept us very busy. They included, among other things, installation of the drilling towers, getting to know the international workforce and stakeholders as well as reporting and permit processes. After all that, the actual underwater drilling and blasting has been launched, and it is proceeding in sweltering conditions according to plan, says Luuri. Terramare s Indian project represents an significant opening to the global drilling and blasting business. Until now, the company s underwater drilling and blasting service has been restricted mainly to the Nordic and Baltic region, and from time to time to elsewhere in Europe. 02 03 TERRAMARE S SIX DRILLING TOWERS INSTALLED ON A LOCAL work barge.

10 PORT OF NAANTALI, SOUTHWEST FINLAND L26 & L27 JETTY EXTENSION NAANTALI JETTY EXTENSION FOR LARGER VESSEL CLASSES TEXT AND PHOTOS: MARKKU SALONEN, PHOTO 3: PORT OF NAANTALI Naantali, located on the coast of Southwest Finland, has a centuries-long history of active port operations, due to its excellent location, naturally deep waters and sheltered harbour area. Since the Middle Ages, there has been significant shipping traffic between Naantali and Sweden. Nowadays, for example, the car ferry route between the Ports of Naantali and Kapellskär has become familiar to many tourists and professional drivers. The Port of Naantali is one of Finland s largest ports in terms of freight volumes. It is a major bulk cargo port for crude oil, refined petroleum products, grain and coal. Bulk cargo accounts for two-thirds of all transport volume. A significant third consists of passenger, truck and trailer traffic carried out with RoRo and RoPax vessels, in which the Finnlines shipping company plays an important role. With maritime traffic steadily increasing, the Port of Naantali will boost its quay capacity by extending its RoRo jetty No. 26/27, which is equipped with two driving ramps. The jetty s longer, sea-facing side, which is equipped with adjustable upper and lower driving ramps, will be lengthened from its present 178 metres to 228 metres. The jetty s shorter, land-facing side will be lengthened from 148 metres to 198 metres. After completion, the full 228 metres of the jetty s deck will be usable. The Port of Naantali s Technical Manager, Jukka Kylmäoja, explains the BOSKALIS AREA NORDIC WWW.BOSKALIS.COM/NORDIC 02

THE PROJECT REQUIRED A POWERFUL PILING ASSEMBLY, BECAUSE THE LONGEST TUBULAR STEEL PILES STRUCK AT THE LOCATION ARE 54 METRES LONG. significance of the project. The extension of the jetty in question will quite simply enable larger RoRo and RoPax vessels to use our port. This project will particularly support Finnlines plans to develop and expand its traffic between Finland, the Åland Islands and Sweden, which Finnlines has already publicly announced, says Kylmäoja Similar development projects have already been completed in Sweden, such as at the Port of Kapellskär, where there has been investment in a total of five quay berths. In Finnlines line traffic between Finland and Sweden, Kapellskär acts as Naantali s partner port in Sweden. Finnlines has stated that these investments at Naantali and Kapellskär will strengthen its service offering as well as its strategy of optimising the ships and routes it uses. This will enable further development of traffic and, at the same time, ensure that Finnlines can utilise all of its types of vessels and thereby make more fl exible use of its fl eet, explains Kylmäoja. JETTY EXTENSION 03 UP TO 54 METRES LONG TUBULAR STEEL PILES Terramare began construction of the jetty extension in early September 27. The 94-metre section to be constructed as a fixed extension of the present jetty has been founded on a total of 39 tubular steel piles. The long tubular steel piles used in the project were brought to the shore of site by truck transports. Due to their length, the piles were delivered in two shorter sections, after which they were welded to their full length at a storage area near the site. As the site is located in exceptionally deep water, up to 20 metres, and the clay layer on the sea bottom is up to 30 metres thick, we performed piling on the seafacing side of the jetty site using up to 54 metres long tubular steel piles equipped > 02 03 04 TERRAMARE S SITE MANAGER HANNU MÄKELÄ (LEFT) AND Managing Director Hannu Tomperi inspect the massive tubular steel piles, equipped with rock shoes, at the work site storage area.

the bottom. After piling, the tubular steel piles were supported, reinforced and concreted. > with rock shoes, says Terramare s Site Manager, Hannu Mäkelä. For this reason, we extended the support legs of our piling unit Meri-Pekka, for example. Likewise, we had to extend the length of a few tubular steel piles at sea, adds Mäkelä. The challenging piling on the sea-facing side was performed from Terramare s powerful Meri-Pekka vessel using a Liebherr HS 895 machine and a Junttan HHK 16S hydraulic 16-tonne pile driver, installed in a 38 metres high piling mast. A corresponding assembly for challenging piling projects cannot be found elsewhere in Finland. FLOATING OF THE TUBULAR STEEL PILES The massive and long tubular steel piles, equipped with rock shoes, were transported by sea by fl oating them to the piling barge. This was made possible when each pile was sealed watertight at its open end. 05 At the site, water was let into the piles, in which case the solid shoe ends were allowed to sink. The sinking and orientation of the piles were controlled and directed with chained hooks attached to lugs on the upper end of the piles, supported by a crane. When each pile was in the correct position and inclination, it was piled into the clay to a depth of around ten metres. The pile was pumped full of water and hammered into place, all the way to 05 06 06 HIGH QUALITY DECK STRUCTURES For the extended jetty will be implemented a solid concrete deck, which will replace at the same time the access bridges between the present jetty and dolphins. The implementation of the concrete structures has begun with the moulding and casting in place, on top of the piles, of the footings that will support the jetty structure. A total of 16 prefabricated 50-tonne beam elements will be installed on top of the cast footings. After installation, pile caps will be cast at the level of the upper surface of the beams. On top of the beams will be installed steel corrugated sheets, on top of which, ultimately, the deck slab will be cast. A concrete structure of this kind is a high quality solution for the type of jetty in question. The concrete structure will be around two metres high, 94 metres long and 10 metres wide, says Terramare s Project Manager, Marko Saarelma. In all, approximately 32.5 tonnes of concrete reinforcement and 3,500 m 3 of concrete were used for the concreting work, adds Saarelma. Terramare will deliver the jetty fully equipped, including fenders, bollards, ladders and edge barriers as well as preparations for electrical installations to be implemented later. Public utility services including water and wastewater piping will also be installed in the jetty. Public utility services will facilitate the emptying of the wastewater and separated bilge waters of the vessels that visit the jetty. The jetty will be completed in March 28. SUPERVISORS PETTERI KANKARE AND TERO PÖYHÖNEN are confident about the solid progress made on the contract. THE FOUNDATION FOR THE JETTY EXTENSION BEING BUILT consists of 39 inclined and straight hammered tubular steel piles, which have been supported, reinforced and concreted.

PERSONNEL NEWS TERRAMARE S NEW FINANCE MANAGER PETRI NIKULA MSC (ECON) IN TERRAMARE, I FEEL THAT I AM IN MY OWN FIELD 13 Finance Manager Petri Nikula, who has joined Terramare, has come to the company to continue the financial management duties of Tapio Leinonen, who is due to retire at a later date. A born and bred Helsinki resident and a family man with two children, Petri Nikula has long experience of the management and production units of major construction and infrastructure companies. The opportunity offered to enter the marine construction sector ignited his interest. I was attracted by Terramare s sector and notable position in domestic and international marine construction. Following an orientation period that took place during autumn 27, I am satisfied with my choice and I feel that I am in my own field. I particularly like the fact that the company has a distinct field of business with its construction services and end products, and that the interesting challenges associated with them are clear-cut, says Nikula. Alongside the company s financial management, Nikula s areas of responsibility include serving in the management team as well as development work in various subareas. The prospects and demand for the services and end products offered by the company are currently strong. Of course, it is also important to understand the cyclicity of the sector, for which it is essential to prepare during the good times. I have, however, been delighted to observe that in Terramare this is precisely how things are done. In this regard and in other ways, I have also been pleased by the fact the company s working atmosphere and cooperation at all levels are healthy. Evidence of this is the long employment relationships characteristic of the company. It shows confidence in the company and a sense of responsibility for achieving common goals. It is exactly these things that I wish, with my experience and ideas, to develop further, explains Nikula. Nikula s job description also includes cooperation with Terramare parent company, Boskalis. Communication with the parent company has been active, because the updating of the common ERP system is currently under way. Perhaps the most surprising thing in my new job has been the extensive network of international contacts, which I did not have to such an extent in my previous positions. But in this respect, the orientation I have received in the company s operations and my duties has been very clear through Tapio Leinonen s valuable experience and guidance. It will be good to continue at his well managed desk. And Tapio, of course, will still be involved in management team duties, so I ll also be able to consult him in the future, concludes Nikula.

14 NEWS EUR 60 MILLION AGREEMENT ON STOCKHOLM NORVIK PORT QUAY CONTRACT TEXT: MARKKU SALONEN, PHOTO: PORTS OF STOCKHOLM Terramare will implement a quay contract for Stockholm Norvik Port in cooperation with its parent company Boskalis. The value of the contract is approximately EUR 60 million. The project was launched in autumn 27, and it will be completed in spring 29. Ports of Stockholm is developing at Norvikudden the Stockholm Norvik Port, which is located around 60 km south of Swedish capital and will be of significant size. A 60-hectare NCC Norvik logistics and business park will also be built in connection with the new container, RoRo and distribution port. Upon completion, the port will cover a total area of 44 hectares. Stockholm Norvik Port will meet the needs of modern container vessels, with deeper fairways, longer quays, larger terminals and efficient transport solutions. A total of seven quay berths will be constructed at the port. The Terramare and Boskalis quay contract includes both retaining quay wall elements and quay sections founded on bored piles. The total length of the berths will be approximately 1,200 metres. The depths of the quays to be constructed will vary between 10.5 and 16.5 metres. The biggest water depth will enable visits to the port of the Baltic s largest cargo vessels. The quay contract was preceded by extensive dredgings and underwater drilling and blastings as well as filling and compaction work, likewise implemented as a collaborative effort of Terramare and Boskalis, and these were completed in March 27. The dredging volumes at that time totalled 690,000 m 3. For the future quay line, a total of approximately 200,000 m 3 was drilled and blasted from above and below the water surface.
