Below you will find some of the interesting offshore projects I have been involved in. For other interesting jobs or projects please click here. Would you like to have my CV? Please send me an e-mail and I will revert back to you with a copy.

The unit is a pure production and quarter's semi-submersible (PQ). It is designed for the Atlantis Field in the Gulf of Mexico. It has favorable motion characteristics for SCR fatigue. The accesses to all production risers are vertical. A large deck area for storage of cargo is also provided.

The  original scope of work for GVA was to design the hull. The scope was increased to include site support during construction, commissioning  and  installation support. I was cost control manager and responsible for change management. 

The design work was done in Gothenburg and Houston. Client was located in Houston. Several trips to USA
