The second semi-submersible rig to be built for SeaDragon Offshore will have a hull corrosion protection system designed and supplied by Cathelco Jotun.
The SeaDragon Offshore project involves the construction of two hulls which will be built in Russian yards and fitted out at Teesside in the U.K. The first of the
semi-submersibles is already under construction at the Sevmash yard for completion in 2008. The second hull is to be built at the Vyborg yard and delivered to Teesside in 2009.
Cathelco Jotun is supplying an impressed current cathodic protection system for the SDO II semi-submersible. Both of the
pontoons will have two transformer/ rectifiers serving a number of hull mounted anodes and reference cells to achieve the optimum current distribution.
