Built in South Korea, the unmissable bright red Goliat undertook a 63-day journey around southern Africa before arriving in the Barents Sea in spring 2015 – when it became the area’s first oilfield in production. This FPSO represents record numbers, advanced technologies and respect for the environment.
The long journey to Norway
Jan: FPSO passes all tests and inspections off the Korean coast.
Feb: FPSO is towed aboard the Dockwise Vanguard.
Apr: FPSO arrives in Norway, at the end of 63 days at sea.
Construction of the Sevan 1000 FPSO is completed at the Hyundai construction site in Ulsan, Korea. The platform is launched and towed out of the construction area.
Workplace safety is a fundamental principle that we share with employees, contract workers and local communities. For that reason, we implement all necessary measures to avoid accidents, including organisational models to assess and manage risk, training programmes, skills development and the promotion of a culture of safety.
Production and injection rely on a subsea system comprising 22 wells connected to the structure via a system of underwater cables.
Goliat’s design incorporates numerous innovations to ensure it operates with complete safety and stability. Operating in the Arctic means working in a highly complex environment, given its rich biodiversity and particularly vulnerable local ecosystems. The project makes use of technical systems that pose a low risk to the environment and to the personnel employed – despite the area’s extreme conditions.
The platform’s assets
The Sevan 1000 floating unit, better known as Goliat, is a 64,000-tonne platform, 107 metres in diameter, with 14 anchor lines and a 100,000 b/d production capacity. To transport it from Korea to the Barents Sea we used the semi-submersible transport ship Dockwise Vanguard.
Following a design contest, Vår Energi, operator of the Goliat Licence PL229/229B, and its partner Statoil, now known as Equinor, selected the model that best met the demanding requirements of offshore facilities. The successful design comprises a circular structure containing a production plant, oil storage capacity and accommodation. Water used is fed back into the tank and the oil produced is temporarily stored before being transported to market by tanker.
Environment and community
Goliat is powered by onshore energy sources via an underwater electric cable, along with energy generated on board the platform. The electrification of Goliat was designed to be safe for people and the environment, reducing CO2 emissions by 50 per cent. Vår Energi’s aim is to maximise the reduction of CO2 emissions, which is why the platform is powered by electricity sourced onshore. The emergency Oil Spill Contingency Plan in the Goliat field has been specifically adapted to the coastline and a fleet of local fishing boats helps monitor impact on the sea.
Eni has never conducted oil and gas exploration and development activities within the boundaries of natural sites included on the UNESCO World Heritage List. In May 2019, we formally committed never to do so and officially instated a biodiversity and ecosystem services (BES) policy as part of our transformation journey. We are committed to long-term investment – looking beyond short-term profit to find ways to help create a more sustainable planet – as recognised in our new company mission, which is in turn inspired by the UN’s Sustainable Development Goals.
