An efficient and compact piston type hydraulic motor is designed to be fitted to the thruster strut as part
of the thruster hub. This motor has variable horsepower (constant torque) characteristics. The hydraulic
motor has optimum running clearances and hydraulic balance to assure sustained high efficiency over
the life of the motor. The inertia of rotating parts is low... parts are symmetrical, providing dynamic
balance and free of vibration.
The hydraulic thruster and propulsion systems are diverse and
include a number of unique, high precision systems, ranging from the
standard "Work Horse" fixed position hydraulic thrusters to the full
Azimuthing/Rotatable Thruster Systems for all subsea dynamic
positioning requirements.
The HPT is a "unique" series of SubSea Hydraulic Thruster Systems, designed to be integrated with an highly efficient piston type hydraulic motor and incorporated to fit to the mounting strut as an integral part of the thruster hub with the Nozzle constructed in fiber composite , high density material. They come complete with Nozzle, mounting bracket and are offered from 12 to 110 horsepower.
The hydraulic motor integrates/mounts to the thruster pod and baring
assembly, therefore extremely lightweight and compact. The design
speed of the propeller averages 28 meters/sec or less, offering efficient
and silent operation. Depending on the Model Series, either a 4 or 5
bladed propellers are used. The thruster systems are pressure
compensated and operational to all ocean depths.
All thruster pod assemblies are manufactured from a high density
...fiber composite with all attaching hardware either 316 stainless
steel or aluminum (hard anodized).
