Goliat After many years of planning, we’re almost there. The Goliat field will be one of the biggest industrial projects ever carried out in northern Norway.

competitive tendering has been carried out and in terms of the value of contracts, more than half have been awarded to Norwegian suppliers.

Goliat will be the first oil field to be developed in the Norwegian sector of the Barents Sea. Although Goliat is a relatively modest project, it will be of considerable importance to the county of Finnmark and the future development of the petroleum industry in the far north. The development costs for Goliat are estimated at more than NOK 28 billion. Goliat will create 150-200 jobs, either on the installation at the field itself or in the operational organisation in Hammerfest. The annual operating costs will amount to around a billion Norwegian kroner and many local suppliers will be able to provide goods and services throughout the operational period. In other words, Goliat is an important building block for Finnmark, northern Norway and the northern regions in general.

Drilling of the oil wells will commence in the autumn of 2011, and in the next four years 22 wells will be drilled into the Goliat reservoirs. These wells will be connected to the floating platform which will be towed out to the field in the autumn of 2013, with the actual production of oil commencing toward the end of that year. There is also gas in the field, but initially the gas and purified water will be re-injected into the reservoir to maintain the necessary pressure for production.

Work is now well under way. The office has been set up in Hammerfest and new personnel are being employed. The Goliat project will use the helicopter terminal and supply base in Hammerfest to transport personnel and equipment out to the field. The construction of the subsea installation is in progress and the platform is being prepared. This will be a floating platform located 53 kilometres offshore. International “NOK 28 billion is seven times the cost of building the new Opera House in Oslo.”

The products of the wells will be oil, gas and water, which will be separated from each other by the processing plant. After that, the oil will be held in storage tanks in the floating platform and loaded into tankers at regular intervals to be transported to a refinery. The estimated recoverable oil reserves in the field are approximately 174 million barrels. At peak production, about 100,000 barrels of oil will be produced daily. Production from the Goliat field is expected to last for at least 15 years. If more oil and gas is discovered in neighbouring fields, it will be possible to link these to the Goliat platform, with a resulting extension of production. The Goliat licence is owned by Eni Norge (65 %) and Statoil (35 %), Eni being the operator.


Sevan 1000 This is what it looks like. The Goliat installation will be a round, floating platform specially designed for the conditions in the Barents Sea. It is 107 metres in diameter at the level of the deck, extends 30 metres below the sea and is called Sevan 1000. It is a floating production, storage and offloading (FPSO) unit which has been designed by the Norwegian company Sevan Marine and will be constructed in South Korea. The platform contains an oil storage unit in a cylindrical hull. The processing plant and accommodation unit with 120 cabins will be located on top of the hull. All personnel working on the floater will have their own cabin. The floater is specially designed to ensure safe operation in exposed, cold regions. It will be enclosed so that wind, snow and ice will not present problems either for the equipment or for personnel working on the platform. Most operations will take place indoors. The hull will be of steel construction, with double-thickness bottom and sides. All equipment will therefore be well protected from waves and any collisions between the hull and other vessels. The hull will have a lifetime of 30 years and the construction will be highly resistant to the effects of material

fatigue. Also important is that the platform will satisfy the strict environmental requirement that no water produced from the wells, or any other polluted water, shall be discharged into the sea. The water is to be purified before being re-injected into the reservoirs. The floater has a greater storage capacity than any of the Sevan platforms in the North Sea – a total of 1 million barrels of oil. Initially, a tanker will arrive every 7 to 14 days to collect the oil. The large storage capacity is an advantage with regard to safety. In the event of bad weather, the oil can be stored in the floater and offloading to a tanker can be postponed until the weather improves. Moreover, an innovation in the Sevan 1000 is a special system of long hoses which enables offloading from all sides of the platform, thereby increasing the safety of the operation. In contrast to ships, the platform is geostationary – it is firmly anchored in place and will not be rotated by currents or wind. This makes it simpler to supply it with electrical power from land, which is more environmentally friendly than onsite generation. A large, floating element at the base of the hull reduces the motion of the waves, improving conditions for those working on board. “Did you know that the diameter of the FPSO – 107 metres – is about as long as the side of a football field, and that the water depth under Goliat is about 400 metres, which is 25 per cent greater than the height of the Eiffel Tower, or the equivalent of 3.4 “Oslo Plaza” buildings stacked on top of each other?”


A job for you? Goliat needs people, both onshore and offshore. Perhaps this is where you will find your dream job?

the Goliat floater must therefore be prepared to work two weeks on and four weeks off.

You may have read and heard that Eni Norge needs more capable people, especially from Finnmark and northern Norway, both for the regional office in Hammerfest and to work on the Goliat platform. Job vacancies will be announced and personnel will be recruited continuously in coming months, both for work on the floater and for positions onshore. These will be involved in the build-up to the start of production in 2013, and will be working in Norway, London, Aberdeen and South Korea.

Eni Norge wishes to recruit manpower from Finnmark county and northern Norway. Eni Norge is making efforts in various ways to encourage young people from the region to apply for work in the petroleum industry. We are involved in a number of projects in schools, colleges and universities.

Four persons are currently in place at the regional office in Hammerfest, and in time this number will grow to almost 50. A large number of people employed here will have a technical background, in the fields of drilling, geology and reservoir engineering as well as management. Many of the positions require college or university education. In time, close to 110 people will be stationed on the platform, where a wide range of professional fields and qualifications will be required. We are talking about jobs such as platform managers, instrument technicians, control room and field operators, logistics and maritime managers, systems operators, electricians, nurses, chefs and cleaning staff. The platform will be operated using a three shift system, which is the standard arrangement for those working on the Norwegian continental shelf. Personnel applying for work on “Goliat’s first Platform Manager is called Trine Lise and she is from Andenes”

Joint venture agreements have been signed with Kirkenes Upper Secondary School and work is in progress to achieve further similar agreements. We are participating in career advisory days and educational fairs. We have a joint venture agreement with EnergiCampus Nord with the objective of making science teaching available to people who live a long way from educational institutions. A number of apprenticeship schemes are being pursued. Among other things, suppliers to the Goliat project are initiating a special apprenticeship scheme for drilling personnel and well technician personnel, placing priority on young people from Finnmark. The Goliat project is planning its own apprenticeship scheme in the fields of mechanical installation, logistics, electrical installation and clerical work. Eni has provided support to the simulator at the Nordkapp Maritime Simulator Training Centre and also awards scholarships to students from Finnmark wishing to take a master’s degree in energy management at the Eni Corporate University in Milan.


Always prepared Innovative methods are used to take care of the golden rule: Prevent discharges of oil. Goliat marks the beginning of a new standard in oil spill protection. The authorities place strict demands on oil spill protection at the Goliat field. We are therefore investing considerable resources and a great deal of time in research and development in the field of oil spill protection. In co-operation with Statoil we have completed projects costing more than NOK 30 million. The results of this research are being used to create oil spill contingency plans for Goliat. To prevent oil spills it is important to monitor production, as this makes it possible for any discharges to be discovered rapidly and combated as close to the source as possible, before the pollution can spread. We deploy sensors and visual monitoring equipment on the seabed and radar on the floater and on vessels. These will provide warning immediately in the event of unforeseen incidents, whether it is light or dark, round the clock. All the production wells will then be shut down until the cause of any discharge has been ascertained. Eni has leased a state-of-the-art standby vessel which will be completed in 2012 and will be permanently stationed approximately 500 metres from the platform. The vessel will be equipped with radar and infrared cameras to detect and monitor any oil spills in any lighting conditions, making it possible to follow the movement of any oil and collect it. The standby vessel may also be used in rescue operations. Two small high-speed boats can

be launched at a few minutes’ notice to rescue personnel from the sea. The standby vessel will also have additional engine power to enable it to assist in towing operations. To prevent any oil spills reaching land, the Goliat field will have an efficient coastal oil spill contingency system. Eni Norge has for several years collaborated with the Fishermen’s Association in northern Norway, Statoil and the Norwegian Clean Seas Association for Operating Companies (NOFO) to enable local fishing vessels to be approved as part of the regular oil spill contingency apparatus. Nobody knows the weather and current conditions as well as their crews, and they can be at the scene rapidly if the worst should happen. About 30 fishing vessels will be equipped so that they can participate in oil spill protection work, and their crews will receive regular training. Oil spill protection equipment will be adapted to this type of vessel and the assignments which the different vessels may be given. Involving the fishing fleet in this way is something new on the Norwegian shelf, but has been tested in other parts of the world. Eni is also providing support for research into new oil spill protection technology. An example of this is a type of “vacuum cleaner” for cleaning beaches, which is being developed by a company called “Vakumkjempen” in Tromsø. However, as has already been stated, the golden rule is to prevent discharges from ever happening.

Electrical power from land Goliat will soon boast the world’s longest submarine power supply cable of its type, which will ensure that emissions of the greenhouse gas, CO2, are halved. The Goliat floater will be supplied with electrical power from land. This is the most environmentally friendly energy supply solution. Electrification in this way will reduce emissions of CO2 by an average of 115,000 tons annually, compared with a solution involving generation at the installation. If Goliat were to produce all its own energy, the emissions would be approximately doubled. The electricity will be transmitted by underground cable from Hyggevatn near Hammerfest and then by submarine cable entering the sea at Kvalfjorden and out to the Goliat platform. The submarine cable itself will be about 106 kilometres long, making it the longest of its type in the world. A transformer station will be built at Hyggevatn, which will be designed by an architect with an eye to the best possible adaptation to the terrain. The cable will be buried in the seabed or covered with stone or heavy fill to prevent trawl nets or other fishing equipment from snagging on it. Does this mean that there will be a shortage of electricity on land? The answer is no. For one thing, the power supply from shore “At its maximum consumption, the Goliat field will use as much electrical power as the households of Hammerfest, Kvalsund and Hasvik use on a normal winter day”

will be combined with supply from a gas turbine generator aboard the floater. If there is a shortage of power, the generator will ensure that there is enough to maintain parts of the production from the field. Secondly, the supply grid in the Hammerfest area will be upgraded. Thirdly, studies of the grid capacity indicate that Goliat can obtain the power it needs for production without overloading the existing supply system. In normal production, Goliat will use between 20 and 40 MW supplied through the cable, with some variation over the lifetime of the field. As a result the available capacity for any other industrial projects will be somewhat reduced. Statnett has submitted a licence application for the construction of a new transmission line between Balsfjord and Hammerfest. An expansion of this type will upgrade the supply grid and improve the local power supply. This may have considerable significance for the future development of renewable energy sources in Finnmark. Most of the electrical power supplied to the platform will be used to power large compressors, pumps and electrical heaters needed for carrying on production. Some will be used to provide light, heating and ventilation. The cable will be arranged with additional capacity making it possible to obtain more power from the onshore supply when the grid capacity has been upgraded. Eni Norge will look into the possibility of full electrification, i.e. the supply of all electrical power from shore. “The power cable is as long as the distance from Oslo to Hamar”


Optimism Whatever you may feel about petroleum operations in the Barents Sea, Goliat will contribute to development, income and interest in settling in Finnmark. The development of Goliat will lead to greater activity both locally and regionally. It means the creation of several hundred new jobs, the purchase of local goods and services, and support for important cultural activities and projects. Just as we feel it is valuable to recruit local manpower, Eni Norge wishes to make use of local suppliers. Although local suppliers may have difficulty offering what we need for the construction of the platform things will be different when operations commence in 2013, and being close to the production site will then be an advantage. Previous experience of similar projects indicates that of the total operational expenditure of NOK 1 billion per year, 30 per cent is passed on to local and regional trade and industry. We already have contact with a number of local suppliers, among other things in the fields of energy, impact studies and graphic design. In addition, we are arranging for local and regional suppliers to be involved in competition for contracts. Invitations for tenders must always be published, and even if local suppliers are unable to offer what we need, we have ensured that contracts will stipulate that suppliers awarded major contracts shall facilitate the use of

local subcontractors and shall participate in supplier seminars. We co-operate with PetroArctic, which is a suppliers’ network with many members representing northern Norwegian trade and industry. The network receives first-hand information about all contracts which are entered into. Companies which are awarded contracts meet to provide information about the content of the supplied goods and services, so that local suppliers are given the opportunity to become subcontractors. We care. We respect the environment, the people and the culture in those places where we operate. We wish to increase people’s interest in settlement in the area, and we therefore support business development and cultural activities in northern Norway, such as: the Varanger Festival, Ingøydagene, SlowFood and the Sea Fishing Festival on Sørøya, the Women’s Conference “Frodig focus” (Fertile Focus) in Kirkenes, the Nordkapp Film Festival, the Snø og Ild (Snow and Fire) Musical Festival, the Insomnia Music Festival in Tromsø, the Reindeer Racing World Cup and the Reindeer Portal. In addition to several northern Norwegian projects in the field of oil spill protection, we have also provided considerable financial support to other research projects, such as: waste management in the arctic environment at several research institutions in Troms, and the Arctic Seas Biodiversity Project, which is managed from Tromsø. Experience from similar projects indicates that during the period of operations, local and regional businesses can make supplies to the Goliat project worth approximately NOK 300 million per year.
