Statoil has announced that construction works on the Johan Sverdrup riser platform have started at the Samsung Heavy Industries yard in South Korea.
In January last year, Aker Solutions secured the contract for engineering and procurement management for the processing platform and riser platform for the field, following which preparations for the riser platform construction started.
The 124m long riser platform is 28m wide, 42m tall, and weighs 23,000t.
Statoil operates Johan Sverdrup with a 40.0267% stake. Other partners are Lundin Norway (22.6%), Petoro (17.36%), Det norske (11.5733%) and Maersk Oil (8.44%).
Johan Sverdrup project director Kjetel Digre said: "As we are starting the riser platform construction, we are taking another important step in delivering the Johan Sverdrup project on schedule.
"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."
The riser platform will receive land-based power that is expected to maintain operation on the Johan Sverdrup field for more than 50 years.
From Johan Sverdrup reservoir on the platform gas will be exported to Kårstø processing plant and oil to Mongstad refinery in Norway.
The Johan Sverdrup offshore project has more than 2,500m² of free deck space, which will be used for equipment and technology and also for realising measures for improved recovery and phasing with regard to future phases of the development.
Construction of the processing platform for Johan Sverdrup is set to begin this month.
