POSITIVE MOOD ON THE HORIZON

T ime really flies by. Over the last three years, I have certainly experienced this in Terramare as the company’s new manag- ing director. We have had very many interesting projects in both Finland and Sweden. We have renewed our organisation as experienced, long-serving personnel have retired, and we have gradually introduced new enterprise resource planning tools to im- prove efficiency. With so much to do and new issues to embrace, time has gone like the wind. In November, we finalised for the next three-year period of Ter- ramare’s Nordic countries and Baltic strategy, which is important for the whole Boskalis Group. Identifying the future market is al- ways the cornerstone of strategy work. In addition, we will focus our efforts on developing the skills and operating practices of our personnel in order to make us more efficient and competitive. An important part of the strategy work was an extensive equipment survey conducted in the spring, on the basis of which we will target new investments in accordance with the projects in the pipeline. Finland and Sweden will continue to be Terramare’s main mar- ket areas, where we will seek suitable transport infrastructure and quay work. The marine construction market in the near future will be dependent on a couple of important factors: the development of the US-China trade dispute and the economic situation in Finland’s main market areas – Germany and the UK. Both of these factors will have an impact on cargo traffic at ports and thereby on marine construction investments. Terramare personnel have always maintained good dialogue with ports and transport infrastructure agencies as we work together to consider the future market situation and needs. Many thanks are due to all our customers and partners for making available to us their time, open doors and hot coffee. Let’s continue these close contacts in the future. To our satisfaction, market discussions have revealed that a rea- sonable number of marine construction investments are planned and that some are already at the implementation stage, with only the final investment decision to be made. For most of the projects, the final impetus will ultimately come from the needs of the paper, pulp and mining industries. In addition, there is a positive mood in the air regarding the development of cruise traffic in the Baltic Sea countries. Terramare is closely involved with, among others, Boskalis Off- shore and Team Arctic Finland in developing offshore wind turbine projects in the Baltic Sea region. Wind power will inevitably be an

important part of renewable energy production in the future. The Baltic Sea region has solid establishment conditions, very shallow water depth and low salinity, which are favourable factors for the construction of offshore wind farms. Future offshore wind turbines will be 3-4 times more powerful than those we have seen to date, mainly built on land. The new, larger wind turbines will require, for example, increased perform- ance from lifting equipment in the construction phase and during maintenance. At Boskalis, we can meet this challenge and share our experience of the projects we have implemented. Thanks to all customers, partners and Terramare personnel for the past year. Let’s also keep the flag of marine construction flying high in the coming year.

I wish our readers a Happy New Year 2020

PORT OF RAUMA TO EXPAND BY SIX HECTARES

TEXT & PHOTOS: MARKKU SALONEN, IMAGE 03: PORT OF RAUMA LTD I n October 2019, Port of Rauma Ltd launched Petäjäs 4, a project of con- siderable size, involving the expansion of harbour field facilities in the Ulko-Petäjäs area. The project is a continuation of earlier harbour field expansions. The expansion, now under way, is the fourth of its kind. In the Petäjäs 4 project, Terramare is implementing a six-hectare harbour ex- pansion. The approximately two year long contract includes both onshore and offshore construction. The expansion will be implemented by seaward rock-filling. The contract also includes dredging of contaminated soil and clay in the area as well as surface, drainage, illumination and landscaping work on the constructed and compacted rock-fill area. The expansion also will also require a fairway modifica- tion and sea marks.

EXTENSIVE DREDGING Initially, dredging of contaminated soil was carried out in the area, followed by dredg- ing of clay. Nearly 300,000 m 3 of clay will be removed from the area, down to a depth of 27 metres. Terramare’s powerful

and versatile grab dredger Kahmari 2 is being used in the dredging. According to the work stages, the vessel uses both clos- able environmental and soft dredging mass buckets. Also available is a claw bucket for use in lifting rocks. Terramare’s four tow- able SCG barges are being used for trans- porting the dredging masses. “The dredging masses, consisting mainly of clay, will be transported and used for fill- ing at Järviluoto Island, located just off the port. It is also currently the place where vis- itors are recognised by their muddy boots and legs,” says Pöyhönen with a smile. MASSIVE ROCK-FILLING WORK “Following relatively substantial dredging, we will then move on to sea-filling itself, which will be carried out using rock waste transported by sea and land. The volume of rock waste to be used for sea-filling is over 800,000 m 3 , for which up to 20,000 truck loads will be needed for the portion to be transported by land. The rock waste brought by sea will go more quickly be- cause the capacity of one loading vessel is equivalent to over 20 truck loads,” says Pöyhönen. Erosion protection will also be construct-

The rock-filling will be done in coopera- tion with local contractors. Naturally, we will try to operate in terms of dredging and massive rock waste transports so as to minimise disruption to port activities as much as possible. As far as the contract is concerned, we have an interesting and comprehensive project ahead of us,” con- cludes Pöyhönen.

ed for the rock-filling of the Petäjäs 4 area. The completed rock fill will be dynamically compacted from onshore before the surfac- ing and public utility services work begins. A 160 metre concrete noise barrier wall will also be built at the new harbour field, and the seaward part of this will be land- scaped with alder tree and sea-buckthorn seedlings. “This contract is important for Terramare and just right for our versatile equipment.

´

COAL AND GRAIN QUAY EXTENSION – FINAL SECTION WILL BE FINISHED!´

a large proportion of the wood chips will be transported to the power plant by land, shipping traffic will increase through wood chip cargos delivered by sea. Our simu- lation showed that the planned extension will shorten overall throughput and waiting times along the entire quay line to an ex- tent that makes the investment worthwhile. We therefore aim to maintain our level of service and avoid situations where ships would have long waits to reach the quay,” says Vainiala. The 82 metre extension at the southern end of the quay line will extend quay berths 15 and 16. The project will bring the total length of the quay to around 460 metres. The entire quay line 15–16–17 will be used to ship coal, grain, cement and salt, among other things. Of these, grain ac- counts for a significant proportion. “The Port of Naantali is Finland’s largest grain port. Up to half of Finland’s annual grain exports travel through Naantali. Huge concrete grain silos, which are operated by Suomen Viljava Oy and once served as the State Grain Store, are located at our port. They have a very high storage capacity – around 300,000 m 3 and 230,000 tonnes. The silos – the crown jewels – owned by the state-owned company Suomen Viljava Oy, are Finland’s largest and play an im- portant role in the export of Finnish grain,” says Vainiala. “Our quay extension project, like our other ongoing investments, will contribute to securing future operating conditions for our customers at our port. I am pleased that Terramare received the contract, because we have a long history of cooperation and even the most challenging situations have always been handled in a good spirit. An even longer quay extension would have been appropriate, if only it would have been possible. But that’s how it goes – when the quay extension is built, the final section of the quay line will be finished!”concludes Vainiala with satisfaction.

T he Port of Naantali is preparing to further serve shipping traffic, which is expected to increase in the near future, by extending its so-called coal and grain quay. The purpose of the investment is to improve the utilisation rate of the quay by creating conditions for safe and efficient cargo handling. The aim is to minimise ship waiting times and access to the quay as well as the total time needed to unload ships along the entire quay line. Yrjö Vainiala , who has served as the Port of Naantali’s Chief Operating Officer for 15 years, is satisfied with the long-con- sidered investment. “The Port of Naantali is preparing for growing shipping traffic, which will be affected by, among other things, the con- version from coal to wood chips in heat production of the power plant located in its immediate vicinity and connected to it by a conveyor. Future storage and shipment of transit grain from the east will also con- tribute to the growth in shipping traffic. The increasing use of large Panamax class ves- sels in grain transports at our port, along with other growing shipping traffic, such as wood chip transports, also influenced the investment decision on the quay exten-

sion,” explains Vainiala. In autumn 2017, a new multi-fuel unit was commissioned at the Naantali power plant, partially replacing a coal-fired power plant that has been in use for around 50 years. The CHP plant, owned by Turun Seudun Energiantuotanto Oy (TSE), produces elec- tricity and steam for industrial customers as well as district heat, which is supplied to Turku and neighbouring towns through one of Europe’s longest district heating tunnels. “In its heat production, Naantali’s multi- fuel power plant will switch completely from coal to more environmentally friendly energy sources and biofuels, such as wood chips, by 2025. This means that, compared to coal, for example, more than two and a half times the weight and five times the vol- ume of wood chips will be required to pro- duce the same amount of heat. Although

of the shore, the longest drilled piles to be installed at the outer edge of the quay are up to 20 metres long. Pile drilling is being carried out from our work pontoons Paalu and Upi. As the foundation for the quay ex- tension, a total of 110 drilled piles will be installed in solid rock. Each pile is around 800 mm in diameter,” says Elo. “The foundation work for the quay exten- sion includes a drilled pile wall contained by a transition slab that will prevent flush- ing of soil from behind it. Around twenty 30-metre anchor rods will be installed in the tight, interlocking drilled pile wall. Backfilling of the quay extension will take place after the completion of the wall,” he explains . After the piling work is completed, the con- crete structures of the quay extension deck will be implemented. The quay’s element beams and shell slabs will be cast in Pan- sio, from where they will be transported to the location using Terramare’s work pon- toon Bolle III. The elements and shell slabs will be installed on top of the quay’s frame beams with the assistance of the multi- purpose vessel Meri-Pekka. After element installation, casting of the quay extension deck, surface work and installation of quay accessories will be carried out. “The work will continue uninterrupted over the winter, so we are all hoping for a mild winter. In other respects, our site area is peaceful and has little impact on the op- eration of the port, so the work is progress- ing really quickly,” says Elo in conclusion.

A CONSTRUCTION DIVER IS A FEARLESS, MULTI-SKILLED EXPERT

01

A construction diver is a multi-skilled expert trained as professional diver whose wide range of skills include the special tasks of the construc- tion industry. A vocational qualification in diving can be obtained in Luksia, i.e. the Western Uusimaa Municipal Training and Education Consortium. The vocational qualification in diving has two areas of ex- pertise: research diving and occupational diving. A construction diver obtains exper- TEXT: MARKKU SALONEN,PHOTOS 01 JA 05: OY BALTIC DIVERS LTD, PHOTOS 02, 03 JA 04: DIVECON LTD DIVERS.FI DIVECON.FI

tise in occupational diving. The training lasts for a year and covers the surface and diving activities of a professional diver. Those who pass the occupational diving qualification carry out diving work with helmet diving equipment at depths of 0 to 50 metres using underwater work equip- ment and tools.

among other things, shore and bottom construction work, concrete and steel con- struction, and pipe installation. The serv- ices of construction divers are needed, for example, in infrastructure projects, hydro- power plants and ports as well as in ship overhauls and inspections. Rescue serv- ices, the Defence Forces and the Border Guard also employ professional divers in their own activities. For Terramare’s marine construction projects, the serv- ices of construction divers are required in, among other things, quay and piling projects as well as in underwater casting, and drilling and blasting work. The tasks mainly include welding, reinforcement and concrete work as well as inspection dives. At sites, construction divers work both above and below the surface. VIEWS BENEATH THE SURFACE Terramare has a long history of coopera- tion with two construction diving compa- nies. The professional divers of Oy Baltic Divers Ltd and Divecon Ltd have been

busy at nearly all of Terramare’s marine construction projects. Both companies operate in Finland and the other Nordic countries. “We have been involved at around 100 Terramare work sites since the early 2000s. I can only say that all of the projects have been unique from a construction diver’s per- spective, but there is one thing they have in common, however, just like our hundreds of other sites. It is the very poor visibility in underwater work. Now and then it is just as if you were working blindfolded,” says Oy Baltic Divers Ltd’s founder Jukka Te- leni with a smile. “Often the visibility is only a few centi- metres, but even at best it is only half a metre. So, despite their interesting work, construction divers do not really enjoy un- derwater views, so familiarising yourself with the site beforehand is the key to de- livering high-quality, safe and efficient un- derwater work,” adds Teleni. Teleni has 40 years’ experience of construction diving. He founded his company back in 1993. Experienced construction diver Jari Ve- nemies founded Divecon Ltd in 2012. For him, the visibility challenges are similarly part of everyday work. “The waters off the Finnish coast, with the exception of the outer archipelago, are a rather murky working environment, but you get used to it and your powers of perception develop rapidly. Detailed familiarisation, a good sense of touch and a precise image of the work site facilitate smooth working. And divers, of course, do not work alone; projects are completed with the assistance of a surface crew,” explains Venemies. “The surface crew play an important role in construction diving. They act as the diver’s lungs by controlling the breathing gas and communicating with the diver by phone. The surface crew also maintain contact with all operators working on the site, so the diver is well in control of the situation,” emphasises Venemies.

EQUIPMENT & WORKING HOURS A construction diver’s basic equipment weighs around 60 kilos. It includes a div- er’s helmet equipped with a diving phone and light and a recording device, as well as a strong dry suit and spare air bottles.

ment. A construction diver may also wear a light frog suit in inspection dives, for example. The maintenance and servicing of equipment and machinery is also an es- sential part of construction diving activities. Dressing properly for the different seasons is also important. “Whatever the season, the basic prin- ciple is that the diver should not get too cold or hot. In addition to technical layers, a woollen garment may be worn under the diver’s dry suit, so even in six-degree water in winter they manage OK. The only challenge in winter is freezing equipment, which must be avoided. In the summer, on the other hand, the surface waters can be really warm, so sweat comes easily as they work,” Baltic Divers Ltd’s Teleni. “A construction diver’s equipment also includes breathing gas tubes. The surface crew monitor the gas supply, and under- water working hours are strictly specified according to diving systems in compliance with safety standards. The breathing gas contains oxygen and nitrogen. In shallow waters, the working time can be up to two hours at a time, but at deeper levels, such as 15 metres, the working time is, accord-

ing to safety regulations, 70 minutes. The breathing gas can, of course, be enriched with oxygen, in which case the working time under water can be extended. Con- versely, a diver must surface to take hours- long breaks between dives in order to re- move nitrogen from the bloodstream and avoid the diver’s sickness, ‘bends’,” says Divecon Ltd’s Venemies. CHARACTERISTICS OF A DIVER Less than 20 or so professional divers grad- uate each year, of which only a few end up as construction divers. The work is mentally and physically demanding, but with the right attitude it is also rewarding.

“A good construction diver wants to de- velop and succeed in his work. With effec- tive teamwork and increasing experience it is rewarding to be able to deal with all kinds of challenges that confront you. Ulti- mately, a satisfied customer is the greatest thanks a construction diver can receive,” says Teleni. “Good construction divers are character- ised by their use of common sense, a cool disposition and team spirit. And challenges are overcome daily with good humour – it’s the right attitude to take,” concludes Ven- emies.

04

A CONSTRUCTION DIVER’S HELMET is a technically complex device. It includes a diving phone as well as illumination and recording equipment. Surface personnel can monitor the diver’s work with the aid of a display monitor. IN ADDITION TO TECHNICAL LAYERS, a woollen garment may be worn under the diver’s dry suit, so even in six-degree water in winter they manage OK.

I gained valuable experience of international teamwork with Swedes and Dutch co-workers, where I was able to use my Swedish and English language skills on a daily basis,” says Vilhelm. “I learned about the Terramare trainee- ship from my teacher and jumped at the opportunity. The marine construction indus- try has impressed me and is definitely a strong option in my future plans. The period work also suited me really well. I worked two weeks on the site and spent week-long breaks in Finland. I’d like to send warm greetings to all of my co-workers in the team. It was a pleasure to work with such helpful and instructive professionals,” says Wilhelm. |

gressed – absolutely no tinkering around! Despite the busy schedule, the working at- mosphere was cheerful and friendly,” says Kaisa. “My duties included, among other things, mass tracking, induction presentations, MVR measurements and reporting. I found the project work to be interesting, and the diverse assignments held my interest right through to end of my summer work period. The work experience was really instructive and I would also be interested in marine construction work in the future,” concludes Kaisa. |

KAISA HARJUNPÄÄ Kaisa Harjunpää, who is in her fourth year of studying civil and community engineering, worked as a work supervisor trainee at the Koirasaaret preconstruction site in Helsinki. “I was inspired to apply for a summer job at Terramare by a presentation given at our university.

13 The diversity of summer jobs, the scale of marine construction and the international dimension provided Terramare summer workers with significant practical experience to support their studies. Terramare would like to thank all of the summer workers for their magnificent work contribution and wishes them every success in their studies!

MATTI KVICK Matti Kvick, who is in his first year of study- ing electrical and automation engineering, received his introduction to the marine construction industry at two different work sites, at Mussalo Harbour and the Nord Stream 2 project. “The work experience at Terramare was really positive. I would even say that the experience was my best to date. I worked for a month at the Mussalo D area quay site, both as a construction auxiliary work- er and in heath and safety duties as well as one and a half months at the Nord Stream 2 crushing plant in rock aggregate quality control, among other things,” says Matti. “It was rewarding to work in a relaxed and helpful working community and in di- verse roles. The huge dimensions involved, such as the Mussalo D area quay elements and their installation, were memorable highlights. Marine engineering is a fasci- nating special field compared to conven- tional civil engineering, and is a strong op- tion in my future plans,” says Matti. |

ELMER JUSLIN Elmer Juslin, a business administration graduate studying to be a civil engineer, worked as a supervisor trainee on the tun- nel site in Gothenburg. The four month long position provided experience of interna- tional operations. “I applied to Terramare for work because I needed more practical experience in my construction industry studies. On the site of the road tunnel running below the River Göta, I was given responsibility for a wide variety of tasks. I made steel and concrete orders, monitored casting work, prepared work-stage reports and much more be- sides,” explains Elmer. “The project was really special and in- teresting, and I found it to be satisfying and rewarding. The international aspect was excellent because I like dealing with matters in different languages such as Ger- man, English and Swedish. I’ve already had discussions about the future, so it could be that I’ll return to this kind of work,” says Elmer. |

LAURA KERNEN Laura Kernen, who is in her third year of her construction studies, worked in the sum- mer at the Koirasaaret preconstruction site in Helsinki. Laura found the summer work position on the internet. “I was really impressed how quickly and smoothly around one million cubic metres of rock waste was shifted into the sea to cre- ate a new land area. On the site, I served as a supervisor and workplace trainee. My supervisor training duties included various work site supervision and reporting tasks. My workplace training duties included maintaining general order and ground compaction with a roller,” says Laura. “During my four and a half months of summer work, I learned a lot of varied and clear practical lessons to support my stud- ies. Right from the start of the work, every- one made me feel at home. In the straight- forward and fair working atmosphere, I was able to be myself and get along very well.

MARINE CONSTRUCTION VETERANS’ MUCH-AWAITED MARITIME MEETINGS

T he membership of the Marine Construction Veterans consists of experienced and retired marine construction professio- nals, who meet every two years or so to remember the past and keep acquainted with the current state of the industry. The events have attracted at least dozens but at best more than 100 participants from all over Finland. Terramare Director Tapio Leinonen , who retired in the autumn 2019, served as the planner and convener of the event held last summer, together with former Terramare Project Manager Pekka Arppe and Construction Manager Paavo Kolari . The venue for the meeting was the Seurahuone Hotel in Kotka. During the event, the members viewed the Mussalo Harbour D area site from the sea, on the cruising vessel M/S VIKLA III. “The event was again attended by a wide spectrum of marine con- struction experts from all personnel levels which, of course, demon- strates the attraction of our industry even after working life. Those who are still working are also welcome to the Marine Construction Veterans’ meetings, as they input into our discussions up-to-date information on the development and prospects of the industry. Ter- ramare has been an active participant, and one representative or other of the management team has always attended all of our meet- ings. I myself joined about ten years ago,” says Leinonen. The first meetings of the Marine Construction Veterans began in the early 1990s, when the convener was the now deceased Juha Tenkanen, who worked in his time for Vesi-Pekka. Since then, around 20 meetings and events has been held. The locations have

mainly been in Finland, but marine construction projects in Sweden have also been visited. “Over time, the employers of the retired professionals have been, among others, Vesi-Pekka, Haka and, since its founding in 1995, Terramare. The older participants of the Marine Construction Vet- erans’ events are over 90 years of age, and the oldest marine construction projects in which members were involved date back to the 1960s. Particularly interesting are projects we worked on together that have been renewed or expanded over the years,” continues Leinonen. “Our shared history and experiences of challenging situations, exceptional conditions, techniques, working methods, problem- solving and successes are popular topics of conversation at our meetings – past times and events come back to life. At the same time, we keep in touch with the current situation in marine construc- tion and the prospects for the industry. The meetings have been memorable, and it has been satisfying to see that the camaraderie of the marine construction professionals remains strong and is a bonding element, even in retirement,” says Leinonen in conclu- sion.

BALTIC PORTS CONFERENCE 2019 T he 2019 Baltic Ports Conference was attended by more than 150 rep- resentatives of Baltic Sea region ports and the maritime industry. The event was held at the Hilton Slussen Hotel in Stockholm in early Sep- tember. The main topics addressed were the current situation and the future of Baltic Sea and global maritime traffic. Visions of future smart harbours, with perspectives on the development of logistics, digitalisation and automation, also sparked interesting discussions. Terramare attended the conference, meeting its market area customers and partners. Projects of interest included the construction of the road tunnel under the River Göta in Gothenburg as well as Stockholm Norvik Port, to be comp- leted next year, for which Terramare has implemented both sea foundation and quay work.
