MANOEUVRING SYSTEMS HYDRAULIC BOW AND STERN THRUSTERS There are seven models of hydraulic bow thrusters in the VETUS sales programme, featuring as standard a hydraulic motor. This hydraulic motor is driven by a hydraulic pump (see page 149). If a hydraulic pump and associated tank are already installed on board, then, in most cases, this assembly can be used for driving the bow thruster too. Some marine engine manufacturers, e.g. VETUS DEUTZ, supply as standard a special P.T.O. (Power Take Off) connection, which greatly simplifies the installation of the hydraulic pump. In addition to the pump and the hydraulic storage tank, VETUS can also supply the required load sensing and control devices, as well as the high-pressure hydraulic hoses, complete with end fittings. All these hydraulic bow thrusters may be fitted to GRP steel or aluminium tunnels or used as a stern thruster using the appropriate installation kit. The three most powerful VETUS hydraulic bow thrusters can also be driven in a safe and efficient manner, using a specially prepared diesel engine, instead of a pump on the main engine. Please see the VETUS powerpacks on page 154. In this case, the matching hydraulic pump will be supplied as part of the powerpack. Installing a powerpack on board can considerably reduce the required generator set capacity, by operating hydraulic functions which are normally electrically powered.
A VETUS powerpack type PM 415 of 24.3 kW (33 hp) is suitable to drive a VETUS bow thruster of 310 kgf. The 410 kgf bow thruster can be powered with the VETUS powerpack type PM 417 of 30.9 kW (42 hp) and the 550 kgf model requires the VETUS powerpack type PVH 465 of 48 kW (65 hp). Please see page 154.
