The EXMAR OPTI® series
With 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 6000 metric tonnes of payload was successfully deployed in the Gulf of Mexico for the Who Dat field in 2011. The larger OPTI 11000® hull was utilized for the Delta House FPS installed in 2015 and the King’s Quay is currently under construction for Murphy Oil. In-house designs are also under development for 4,000 up to 30,000 metric tonne units. The OPTI® series is a standardized design and fully scalable to meet specific load requirements in all environments.
Features of the design include unique 5-sided columns connected to a ring-pontoon which provide superior motion characteristics, reduced structural 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 overall cost and lead time for FPS deployment.
As part of its commitment to continual improvement and the implementation of lessons learned, improvements to the OPTI® design include un-manned capability, carbon capture readiness and offshore renewables applications.
