Abstract (en)
The present invention provides a marine seismic survey vessel, which vessel includes at least one propeller for propelling the vessel, and driving means for driving the or each propeller, said driving means being capable of driving the seismic survey vessel at a selected surveying speed through the water (e.g. of up to nine knots) and the or each propeller being selected such that substantially no cavitation occurs adjacent thereto at said selected surveying speed. Preferably the marine seismic survey vessel includes a propulsion system comprising a first prime mover, and a second prime mover, the first and second prime movers being operably connected to the propeller(s) and the first prime mover being an electric motor or a diesel electric motor. Preferably, the propellor(s) of the marine survey vessel are highly skewed. Preferably, the hull form of the marine seismic survey vessel is arranged to produce low wake field turbulence, in particular by suitably streamlining a skeg(s) of the propeller(s) of the vessel.
