Statoil: Njord A towed to Kværner Stord

Published by
Oilfield Technology,

Oil and gas production on Njord should in fact have ceased a long time ago. When the field was developed, it was scheduled for production until 2013.

“We have been able to recover more of the reserves than originally expected, and following new discoveries and the Snilehorn development, field production will continue for at least ten more years. This is a big and important project and Statoil is working closely with the partners and suppliers to succeed,” says Snorre Grande, project director for the Njord Future project.

The commercial basis for the Njord A renovation still requires production from Njord and Hyme, where we have identified 177 million boe remaining to be produced.

Scheduled for tie-in to Njord, the Snilehorn discovery contains 66 million bbls. These two fields combined will provide more recoverable resources than the Gina Krog field, which is currently under development on the Norwegian continental shelf.

To enable Njord A to receive these resources, the hull must first of all be reinforced. Extensive renovation on board the platform will also be made.

A new chapter in the history of Njord

Njord has been on stream for 6821 days and 54 wells have been drilled, including exploration wells. A total of 167 million bbls of oil and 41 billion Sm3 of gas have been produced since the start-up almost 20 years ago.

We are about to pass a key milestone in the history of Njord as the Njord A platform comes ‘home’ to Kværner Stord, where it was constructed in 1997. At that time the yard was called Aker Stord. In April this year Kværner Stord was awarded the framework contract for renovation of the platform and pre-engineering will continue throughout this year. The framework contract also includes an option for the platform renovation work.

“We have been preparing the platform on the field since March. Marine operations have been carried out safely and successfully, and well within the planned execution period. It has been great to take part in the Njord A platform’s voyage to Klosterfjorden, where Kværner is now taking over,” says Knut Lorang Alvheim, project manager for marine operations on board Njord A.

The Njord Future project will also be prepared for further phasing-in of third-party fields. A new and fortified Njord platform may furthermore become a field centre in the future for new discoveries in the area.

Njord Bravo

Production on Njord and Hyme was shut down in June and preparations for the Njord A tow-in have continued through the summer, including tasks such as securing of wells and facilities before the actual disconnection.

The Njord Bravo storage vessel arrived at Umoe Sterkoder in July. Extensive work is currently being made to examine the vessel’s condition closely. A decision will be made this year whether it is possible to extend the life of the storage vessel or we need to construct a new vessel.
