Marine Bow Thruster
Application
Bow thruster provide thrust to the vessel to move sideways. Bow thruster are divided into: controllable pitch bow thruster(CP), fixed pitch bow thruster(FP), contra-rotating propeller bow thruster, single propeller bow thruster and retractable bowthruster. The contra-rotating propeller bow thruster realizes the smaller propeller diameter of the same power products, the larger thrust of the same diameter design of bow thruster. At the same time, the left and right thrust are basically coincident.
According to the source of power, there are three types: variable-frequency driven, hydraulic driven and diesel engine driven. According to the drive types, there are L-drive bow thruster and Z-drive bow thruster.
From the design stage to dispatch, our internal quality assurance systems fully comply with marine class standard. In addition, third- party surveyors will check the process of design and fabricating to ensure the marine winch complies with all relevant specifications.
