The SEVEN ATLANTIC has been specifically designed for saturation up to 350 métrés below sea level and features an integrated saturation diving System. Suitable for worldwide operation, she is the highest class DP vessel capable of operations in severe weather conditions. In order to enhance the FMEA safety case, the vessel is designed with full triplication of ail DP, propulsion and manoeuvring related Systems and subsystems, which allows the vessel to maintain DP3 operation with a System or component out of service. The integrated saturated diving System on the SEVEN ATLANTIC has a total capacity of 24 divers: eight diving teams with three members each. The maximum continuous working diver capacity is for divers deployed by two diving bells carrying three divers each. The diving System is designed for operations in depths of up to 350 métrés. The vessel has a total of five moon pools, two for the diving bells, two for the observation class ROVs, and one for lowering instruments and tools to the seabed. The vessel's stability significantly reduces dependency on port calls for crew change, and as an example, helicopter crew changes of 38 personnel hâve been safely conducted in force seven conditions. She can also operate at ease in fully developed sea conditions in excess of 4.5m Hs. The SEVEN ATLANTIC has surpassed her design objectives and has received a number of customer commendations, which is testimony to an exemplary design and a committed team, both onshore and offshore Purchaser Subsea 7 Delivery year 2009
