At Oceanology International 2012, two Motion Reference Units from Kongsberg Maritime’s position reference specialist division, Kongsberg Seatex, Norway, have been showcased. The MRU 3 is a completely new model within Kongsberg Seatex’s 5th generation of roll, pitch and heave motion sensors. It is especially designed for heave compensation applications including real-time heave compensation of echo sounders and active heave compensation of offshore cranes. It provides heave measurements to meet IHO standards and achieves high reliability by using solid state sensors with no rotational or mechanical parts.
Another new model to the fifth generation of MRUs, the new MRU E, is specially designed for use in marine applications that require an extended temperature range. It can operate at ambient temperatures from -25 to +70°C and can be installed on open decks, inside cabinets or on bulkheads.
