INDEPENDENT PLATFORM RIG

Fast Moving Workover Rig

The FMWR has been designed as a self-erecting, independent platform rig.

– Small footprint, 12m x 30m. Its flexibility allows a set-up and skidding on beams from 9 to 14m spacing

– Self-erection with its own dynamic load service crane (15mT@20m). This crane is mounted with a classic 8mT jacket crane

– Reduced rig-up / rig-down time thanks to a modular concept

– Independent power plant

– Zero discharge rig

– Meets most stringent requirement of regulatory groups including ABS, DNV, BV, Lloyd’s

DIETSWELL has been covering the whole value chain for this particular project, covering design from scratch, detail engineering, procurement and contracting activities, construction follow-up. The construction has been performed in France, includind preliminary tests and commissioning. Then this modular and independant platform rig has been packaged and sea transported to be installed on a platform offshore Lybia. It has remained in operationnal state ever since. Such project stresses the capacities of DIETSWELL to deliver fit-for-purpose engineering in the energy industry.
