Activity 9 - Propulsion and Auxiliary Systems

Steering system

The B-Class Atlantic 85 Class Lifeboat is fitted with the

‘Seastar’ Hydraulic Steering System as standard. It is

the same system that is fitted to the B-Class Atlantic 75

Lifeboat. The steering wheel is fitted to a hydraulic pump,

which transfers hydraulic fluid from one side to the other

of a two-way hydraulic steering ram, which is fitted to the

port engine.

‘Seastar’ hydraulic steering system

The ‘Seastar’ Hydraulic Steering System comprises three

main items:

•  A combined helm and resevoir unit.
•  An emergency by-pass valve.
•  A steering cylinder.

As the hydraulic system operates at a comparatively

low pressure, all three items are connected with simple

thermo-plastic pipes.

It should be noted that the operating system can be

operated up to a maximum pressure of 1000psi. At this

pressure the pressure relief valves in the combined helm

and resevoir unit will lift.

A by-pass valve is fitted which, when opened, allows a

free flow of hydraulic fluid from one side of the steering

cylinder to the other.

Should a failure occur in the system, the boat can be

steered manually by opening the bypass valve and fitting

an emergency tiller to the starboard outboard engine.
