Project Profile

Value: CAPEX US$6.2 billion (2009-2015), OPEX US$180 million (by ENI)
Location: PL229 BLock 7122/7, Barents Sea, Norway
Start-up Year: Q4 2013
Reserves: 180 million barrels of oil and 8 bcm (283 bcf) of gas
Production: 72,000 bopd (June, 2016)
Water Depth: 1,500m  

Goliat is 85km northwest of Hammerfest and 54km southwest of Snøhvit and the water depth in field is approximately 1,500m. The Norwegian Petroleum Directorate has revealed that the Barents Sea Goliat discovery contains as much as 200m boe, made up of 75% oil and 25% gas. The field could produce at plateau almost 100,000 boe b/d, of which 80,000 b/d would be oil. Goliat is likely to share some facilities with Snohvit. Gas could be initially reinjected into Goliat and then be connected to the Snohvit pipeline and transported to the Melkoya processing plant near Hammerfest, or alternatively a compressed natural gas (CNG) export solution could be considered. The project costs surged to 46.7 billion crowns (US$5.62 billion) from an original estimate of around 30 billion crowns in 2009, when the development plan was approved.

DNV GL: Contract is for a 3-year term, with an option for a 2-year extension, consisting of planning and carrying out inspections of static equipment, load-bearing structures, and offloading and anchoring systems aboard the Goliat floating production, storage, and offloading unit during its operational life

IKM (Norway): Subsea engineering and topsides work

Eureka Pumps AS: Contract to provide support to Eni Norge with service, overhaul and repair of pumps and related equipment, including but not limited to the following: installation, commissioning and start-up assistance; on-site services; onshore services; spare parts and training. The agreement is valid for three years with an option for two plus two year’s extension period.

IKM Elektro AS: Contract for the provision of overhaul and repairs of electric motors, generators and heaters on the Goliat platform. The contract has a duration of three years with options for extensions, and will be performed as an Integrated Operations project. Both companies expect that the contract will utilize local personnel and IKM Elektro will use the already established IKM facilities in Hammerfest as the operational hub.

Aptomar: Oil spill detection and combating capabilities and a holistic emergency response management system, focusing on rapid detection and controlled combating of a spill, in addition to protecting the safety and integrity of both personnel and assets onboard and around the FPSO. Aptomar’s field monitoring system on the Goliat field allows 360° surveillance coverage from the FPSO hull outward, plus the ability to detect small and large oil spills independent of light, wind and weather conditions, and estimates the relative thickness of a spill and where it is drifting.

Floatel International AB: Contract to hire Floatel Superior, an accommodation and construction support vessel, as a flotel for the Goliat field in the Barents Sea. Floatel Superior was built at the Keppel FELS shipyard in Singapore and completed in March 2010. The vessel is operated by Floatel International AB of Gothenburg. It is registered in Bermuda and classified by DNV GL.

Technip Norge AS: Manned underwater operations connected with the floating production, storage and offloading (FPSO) vessel of the Sevan 1000 type, along with subsea well templates. The operations will also include the installation of risers. Water depth at the site is 370 metres. The facility has a draft of 19 metres and the underwater activities will not go deeper than 30 metres below the surface. The diving operations will be performed using the Technip Seahunter light diving craft. The operations will begin during the second quarter of 2015 and are scheduled to last for 26 days.

First Subsea: Installation of bend stiffener connections for gas lift and production risers, power cables and umbilicals, for the Goliat FPSO in the Norwegian Barents Sea. The First Subsea Type II BSC comprises a ball and taper connector attached to a bend stiffener, which is pulled into a pre-machined I-tube. The connector is self-energising and self-aligning, and features First Subsea’s Automatic Release Clamp (ARC) enabling both diverless and ROVless bend stiffener connections.

ABB: Commissioned a subsea power link for Eni Norge’s field in the Barents Sea. The power link will supply power from the Norwegian grid to the new Goliat FPSO. The 105.5-kilometre subsea power cable system is the longest of its kind in the world. The 75 MW, 123 kV capacity link will supply about 50% of the platform’s electricity needs from shore, cutting carbon dioxide emissions by half as a result of reduced fossil fuel consumption in the gas turbines. ABB’s turnkey solution includes the design, engineering, supply, installation and commissioning of the cable system. The dynamic cable section hangs in the water between the platform and the seabed and has been specifically designed to withstand substantial mechanical stress and fatigue caused by currents, waves and the vertical movement of the platform.
