The contract includes delivery of new equipment as well as maintenance and storage of existing materials. Aker Solutions will provide new tapered stress joints and a complete tension system for the Heidrun tension leg platform. Furthermore, it includes refurbishment and preservation of numerous stress joints, tensioning cylinders, tensioner frames and associated components.
The work will be carried out by Aker Solutions' drilling technologies business in Horten, Norway, and the storage will be in Kristiansund on the Norwegian west coast.
The four-year contract, whose value was not disclosed, can be extended for another four years.
(Production risers are vertical pipelines between the seabed and a floating production facility. They are used to transport produced hydrocarbons, as well as production materials, such as injection fluids, control fluids and gas lift.)
