Eni Norge AS (Eni) has received consent from the Petroleum Safety Authority (PSA) for manned underwater operations related to the Goliat floating production, storage and offloading (FPSO) vessel.
Eni is the operator of the Goliat oil and gas field, 85 km north-west of Hammerfest. The field is being developed using Goliat FPSO of the Sevan 1000 type, along with subsea well templates.
According to the PSA, Eni will perform the underwater operations as part of the installation of the FPSO on the field. The operations will also include the installation of risers.
Water depth at the site is 370 metres. The FPSO has a draft of 19 metres and the underwater activities will not go deeper than 30 metres below the surface, the PSA says.
The diving operations will be performed by Technip Norge AS, using the Technip Seahunter light diving craft. The operations are set to start during the second quarter of 2015 and are scheduled to last for 26 days.
