Raytheon Anschütz reports that it has completed the supply of gyro compass systems to two 25,000 dwt polar class heavy transport vessels for operation north of 70° latitude.

{mprestriction ids="1,2"}The vessels, Audax and Pugnax, were built at Guangzhou Shipyard International (GSI) in China for Red Box Energy Services in accordance with DNV NAUT-AW rules and the highest ice class notations.

Both are capable of operating year round in polar conditions – including temperatures below  -40° C . The vessels have since been deployed for module transportation for the Yamal LNG project in Russia.

Raytheon Anschütz supplied the vessels with a dual gyro compass system and steering gear control system, along with a NP 5500 fully adaptive autopilot. This includes automatic speed- and latitude error correction, an individual speed error correction mode, and an independent transmitting magnetic compass path.{/mprestriction}
