Construction start on Johan Sverdrup riser platform

Following the commencement of the platform construction work at the beginning of June 2016,work has now started on the Johan Sverdrup riser platform.

The preparations for the riser platform construction have been in place since January 2015, when Aker Solutions was awarded the contract for engineering and procurement management for the processing platform and the riser platform for Johan Sverdrup.

“As we are starting the riser platform construction we are taking another important step in delivering the Johan Sverdrup project on schedule,” said project director for Johan Sverdrup Kjetel Digre.

“As of today Samsung Heavy Industries will gradually be given more responsibility for ensuring that the riser platform is built without any HSE incidents and that the platform is delivered according to plan and cost. We have an ambitious project plan for Johan Sverdrup, and we depend on high-quality and precision work from Samsung and more than 100 equipment package suppliers when they are delivering the riser platform and the processing platform topsides,” says Kjetel continued.

The riser platform is to be of key importance on the field centre, as it will be the receiver of land-based power that will maintain operation on the Johan Sverdrup field for more than 50 years. From this platform the oil and gas from the huge Johan Sverdrup reservoir will be exported to land, to Kårstø (gas) and to Mongstad (oil).

Future possibilities

The riser platform also represents the future of the Johan Sverdrup field.

“Our Johan Sverdrup development is based on 40 years of experience from the Norwegian continental shelf. We know that by working hard every day we are able to improve the oil and gas recovery and extend the life of our fields.

During the 50 years of production from Johan Sverdrup, innovation and new technology will open up new possibilities. That is why we, for the first time in an offshore project, have more than 2500 m2 of free deck space, which will be used for equipment and technology that may improve recovery and extend the life of Johan Sverdrup,” said Digre.

The free space will be used for realising measures for improved recovery and phasing in future phases of the Johan Sverdrup development, and any other future discoveries on the Utsira High.

The riser platform is the largest of the four platforms constituting the Johan Sverdrup field centre. The platform will be 124 m long, 28 m wide, 42 m tall, and have a total weight of 23 000 t.

Construction of the processing platform (P1) for Johan Sverdrup will start during July 2016.
