ORCA Self Elevating Platforms
The design of the ORCA series of self-elevating platforms was a collaboration between Bennett Offshore and the Offshore Technology Development group of Keppel Offshore & Marine. The first ORCA 2500, customized for the Middle East and North Africa, was delivered to a Qatari rig operator in February 2016. A high-specification ORCA 3500 is under construction by Keppel FELS for delivery in Q4 2017. Pictured above is the ORCA 3500-WIND, designed for installation of offshore wind turbines.
