Electro/Engine Driven Hydraulic Powerpack
In Electro/Engine drive system, an Electric Motor driven / Engine Driven Powerpack, is providing the pressurised oil to the system. Hydraulic pump is coupled to a shaft, driven by Engine/Electric Motor
This type of Electro-Hydraulic Powerpack Driven by Electric Motor, are used in Heavy Barges and Mini Ships, where Generators are used to power the steering system
Photograph below shows a typical Engine Driven Powerpack fitted in a fishing vessel, with sea-water cooled oil cooler.

Pair of Semi-Balanced Hydraulic Steering Actuators
A Pair of Semi-Balanced Hydraulic Linear Actuators are planned, to turn the tiller-arm to both sides of the vessel, smoothly and precisely. Oil supply ports are provided on both sides of the these actuators, through which ,oil can be supplied to the pistons of the actuators.
As pressurised oil is supplied from Helm pump to the Linear Acuator, the piston-rod will move forward or backward depending on to which supply port ,oil is provided The pistonrod-end/Ram-end of this actuator has a flexible connector ,which can be coupled to the Tiller-Arm As the driver rotates the steering wheel to oneside oil filled in the circuit flows from one side of the circuit to the other side of the circuit,enabling the Piston rod of Actuator to move from one side to the other . When the driver rotates in opposite direction the same process will repeat resulting piston-rod movement in the opposite direction

Oil Transmission System
Flexible Hoses, as well as Coated Seamless Steel Tubes are recommended for transmission of oil from the Helm Pump to the Hydraulic Actuator.
In small boats, Flexible Hoses will be sufficient. But in longer vessels,Coated Seamless Steel tubes are recommended between Flexible Hoses at the Helm Pump-end and Actuator-end.
