PSA gives trio go-ahead for manned underwater operations

Offshore staff

OSLO, Norway Statoil, Gassco, and ExxonMobil have received consent from Petroleum Safety Authority (PSA) Norway to perform manned underwater operations for one year. Statoil has signed framework agreements with Technip Norge AS and Subsea 7 Norway AS to provide these services.

The consent applies to manned underwater operations down to 180 m (590 ft) and covers both planned and undefined operational and project tasks, as well as emergency repairs. 

The PSA is to be informed in advance when the individual planned tasks are to commence. Before potential operational and project tasks or activities linked to emergency repairs begin, the companies must provide the PSA with supplementary information about the specific activities.

Technip will be using the dive support vessels (DSV) Skandi Arctic and Wellservicer, and the light diving craft (LDC) Technip Seahunter. Subsea 7 will be using DSVs Seven Falcon, Seven Atlantic, and Seven Pelican and LDC Seven Spray.

Statoil has applied for consent for its own activities and on behalf of Gassco. In addition, ExxonMobil has submitted its own application to supplement Statoil’s. The PSA has given consent to all three to emphasize that the individual company is responsible for ensuring that the consent is adhered to properly and in accordance with regulations.
