Sagem (Safran) has won the contract from OSI Maritime Systems Ltd. against an international field of bidders, to provide the inertial navigation systems for the Royal Canadian Navy’s six Harry DeWolf class offshore patrol vessels.(1)
Each of these arctic patrol boats will be outfitted with two BlueNaute® attitude and heading systems from Sagem.
The new-generation BlueNaute® system is based on a proprietary Sagem technology, the hemispherical resonator gyro (HRG). Initially used for space applications, this technology offer a major improvement in terms of maintenance and total cost of ownership compared with previous generation navigation systems.
The BlueNaute® system is capable of operating in the harshest environments, which means that it is ideally suited for the long-duration missions in arctic zones – up to four months – assigned to these Canadian patrol boats. The system is highly reliable, featuring mean time between failures (MTBF) exceeding 100,000 hours. It also provides services that fully match commercial shipping needs, in compliance with the requirements of the International Maritime Organization and the SOLAS (Safety of Life at Sea) treaty.
This latest contract consolidates Sagem’s success in the inertial navigation market for offshore vessels: the US Coast Guard had already selected the BlueNaute® system in 2015 to modernize its Reliance class medium-endurance cutters and the Juniper class seagoing buoy tenders.
The BlueNaute® system is produced in Sagem’s plant in Montluçon, in the Auvergne region of south-central France.
A world leader in navigation systems and equipment, Sagem understands and applies all inertial technologies: mechanical, laser, fiber-optic, vibrating, MEMS. It has over 60 years of experience in making navigation systems for civil and military applications, deployed worldwide.
(1) The Henri DeWolf class offshore patrol boat, previously known as the Arctic Offshore Patrol Vessel, is part of Canada’s national icebreaker vessel replacement program. Commissioning is now scheduled to start in 2018. The ship is 103 meters long (340 ft) and displaces about 6,300 metric tons.
