More gas from Gullfaks C

From the autumn of 2001 it will be possible to transport four times the amount of gas from Gullfaks C as at present. Capacity will be expanded to 16 million cubic metres per day.

The increase will occur in connection with the development of the Gullfaks South and Rimfaks satellite fields in the North Sea. Production from the Gullfaks C platform is shut in from 16 to 30 October due to modifications in connection with the Gullfaks satellites phase 2. Another three turnarounds will take place in the course of the next two years.

Platform manager Leif Løchen says that 35,000 work-hours will be spent during the 14 days of this first turnaround. Contractor Aker Offshore Partner has about 180 personnel on the platform. This means that there are 400 people currently living and working on board.

"The living quarters can actually only accommodate 330 people, so it's a full house here now. This demands flexibility, consideration and vigilance on the part of everybody," says Mr Løchen.

He points out that this is important in order to create an atmosphere of collaboration and satisfaction, and to avoid accidents and injuries. According to the platform manager everything has gone very well so far.

The Gullfaks satellites will help to make Gullfaks C a major gas exporter from 1 October 2001. The project has a cost framework of NOK 6.8 billion, of which 1.5 billion will cover conversion of the platform. This includes a facility for gas production and upgrading of several systems. Production and export pipelines will be pulled into the platform.The project also includes installation of subsea templates with well equipment and drilling and completion of nine wells. Two flowline bundles totalling 14 kilometres will be built and installed. These lines will transport gas and oil from the satellites to Gullfaks C.

Gas will increasingly take over from oil towards the end of the field's lifetime. In the final 10 years of the production period, gas production will dominate. The satellite fields contribute strongly to extending the lifetime of the Gullfaks field by about 10 years. The field is expected to produce until 2020.
