Contractors:
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.
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.
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.
