GLASGOW, UK – Fugro has supplied a structural monitoring system to Exxon Neftegas, operator of the Sakhalin-1 consortium.
This is one of the world’s largest floatover platforms, designed so that the topsides are isolated from the base using friction pendulum bearings (FPBs).
The area is prone to 18-m (59-ft) waves, 2-m (6.6-ft) ice floes and temperatures ranging from -44ºC (-47.2°F) to +32ºC (90°F).
Fugro was asked to provide an integrated system to monitor the platform’s seismic response and the performance of the FPBs. The solution also had to satisfy the Russian GOST and GOST-Ex certification requirements, and to withstand the environmental conditions.
The contractor configured the equipment at its complex in Glasgow, Scotland, using a proven sensing and data acquisition equipment. The company’s SIMS data acquisition software allowed additional functions requested by the client to be incorporated during the system build.
Fugro adds that the factory acceptance test was witnessed by WorleyParsons, lead contractor for the project, before the equipment was shipped to the platform for installation.
