Statoil chooses Allseas vessel to install Johan Sverdrup topsides

STAVANGER, Norway -- Statoil has signed a contract with Allseas for the installation of three platform topsides on Johan Sverdrup field. Allseas’ Pioneering Spirit will be installing the topsides for the drilling, processing and living quarter platforms.

Allseas will transfer the topsides to Pioneering Spirit before they are transported to Johan Sverdrup field. On the field, Pioneering Spirit will install the topside on the steel jackets.

The drilling platform topsides will be installed in 2018, and the processing and living quarter topsides will follow in 2019.

The vessel has a lifting capacity of 48,000 tons. The heaviest lift will be carried out during the installation of the processing platform topside that weighs around 26,000 tons.

After the topsides have been assembled onshore they will be transported offshore for installation. This allows more work related to completion and testing of the topsides to be performed onshore. The number of offshore man-hours will be reduced, which reduces both time and costs.

Constructed in South Korea, Pioneering Spirit is currently being completed in Rotterdam.
