Aluminium outfitting

aasta hansteen

General info

The Aasta Hansteen field will be run from Harstad, Statoil’s new Operations North organisation. The supply base will be located in Sandnessjøen and the helicopter base in Brønnøysund. The planned field development includes a SPAR platform, which will be the first such installation on the Norwegian continental shelf. SPAR is a floating installation consisting of a vertical column moored to the seabed. The installation features conventional topsides with processing facilities.

Structural engineering

The topside equipment consists of many aluminium structures and outfittings, where the design and engineering has been awarded to Bayards. Among these structures are: stair towers, wind shields and miscellaneous platforms. My primary role for this project is to create the basis of design documents, where all of the structural requirements and input parameters are set. This includes complex project specific load definitions, such as wave run-up, green water, acceleration loads and blast loads.

Calculations

I performed full structural calculations for the antenna tower, which is clearly visible on top of the living quarter of the topside. Also, the platform connected to the helideck and a cantilevered staircase are engineered.
