The EXMAR OPTI® series
With the increasing demand for re-deployable, fast lead- time-to-production units, EXMAR’s OPTI® series of semisubmersible platforms have been designed as an optimized and scalable solution for floating production systems (FPS). OPTI-EX® with 6,000 metric tonnes of payload was successfully deployed in the Gulf of Mexico in 2011, with its much larger successor the OPTI 11,000® hull (11,000 metric tonnes) also delivered to the satisfaction of the same client for Delta House in 2014. In-house designs are also under development for 16,000 and 22,000 metric tonne units. The OPTI® series is fully scalable to meet specific load requirements.
Features of the design include unique 5-sided columns connected to a ring-pontoon which provide superior motion characteristics, reduced steel weights, and allow for the use of EXMAR’s FAST™ (Fully-Aligned Stress joint Trimming) riser pull-in method. This permits the safe, reliable and highly efficient installation of production and export risers, which significantly reduces overalls cost and lead time for FPS deployment in the world’s harshest deep water environments.
EXMAR Offshore has also designed, built, installed, and operated the floating production, storage, and offloading (FPSO) unit Farwah with 900,000 bbl storage capacity.
The vessel, which was commissioned by TOTAL in 2003, was operated by EXMAR OGIS in the Mediterranean off the North African coast.
