Research Vessels

With frequent operations in polar and coastal environments, a requirement for water lubricated propulsion is often expected. Typically, vessels will have water lubricated shaft lines with composite bearings meaning zero risk of any hydrocarbon (even EAL type) leaking into the ocean. Furthermore, operation in a polar environment means the vessel must be capable in ice fields – which requires additional strengthening of the ship structure to break through the frozen seas. 

When sailing through ice, the regular impacts on the vessel give high shock load accelerations – for which the propulsion system needs to be prepared. The composite type bearings used in water lubricated shaft line applications are far more robust in such shock applications than their oil-lubricated white metal bearing alternatives.
