The riser platform construction start was marked at the Samsung Heavy Industries yard in South Korea.
The preparations for the riser platform construction started already in 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.
The platform construction work commenced in the beginning of June 2016.
“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 Digre.
The riser platform will play a key role 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).
The free space will be used for realizing 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 metres long, 28 metres wide, 42 metres tall, and have a total weight of 23,000 tonnes.
Construction of the processing platform (P1) for Johan Sverdrup will start during July 2016.
