Subsea 7 has selected BMT Scientific Marine Services (BMT), a subsidiary of BMT Group, to supply the riser monitoring system for the Aasta Hansteen Spar, about 300km off the coast of Norway.
The integrated system includes an innovative suite of remotely operated underwater vehicles (ROV) deployed strain, motion and position sensors to monitor steel catenary riser (SCR) response in the Touch Down Zone (TDZ). Data acquired by the riser monitoring system will be used to validate both the spar and SCR design.
The Aasta Hansteen Spar will be the world’s largest spar platform and the first of its kind on the Norwegian continental shelf. Furthermore, the spar will be the first ever deepwater floating production platform (+1000m) installed in the harsh environment north of the Arctic Circle utilizing SCRs.
