Sevan deepwater drilling rigs for harsh and arctic environments

The three existing Sevan deepwater drilling rigs provide a robust and stable platform for drilling operations. The enclosed moonpool, the large load carrying capacity and fuel efficient dynamic positioning (DP) operation are valued by operators. Based on the experience from our existing deepwater drilling units, we have developed units for operation in harsh and arctic environments. These units are winterized and have ice-strengthened hulls, in addition to having the same benefits as the existing Sevan units. The main focus in the design development has been to provide an efficient drilling factory with minimum environmental footprint. Reduced emissions are achieved by use of hybrid power solutions, variable speed drives and waste heat recovery.
