Steering gear is one of the necessary equipment in the ship, serves to help
ships turn to the left (port side) and right (starboard side). According to SOLAS,
1974, steering gear should be able to rotate the rudder from 35º right to 30º left or
vice versa within 28 seconds. To move the rudder, steering gear requires hydraulic
pressure enough. In operation, the steering gear is leaking hydraulic oil thus affecting
the performance of the operation of the steering gear.
In order for the safety and smoothness in motion if the ship is not impaired or
component damage is more severe, then in this paper, the authors use the method
approach Hazard Analysis and Operability Studies (HAZOP). HAZOP method used
in analyzing the hazards and risks inherent in a system. HAZOP method is a method
of systematic hazard identification thorough and structured to identify various
problems that disrupt the course of the process and the risks inherent in an equipment
which pose harm to humans or the facilities in the system.
After doing research using the Hazard Analysis and Operability Studies
(HAZOP), known impacts and risks as well as the cause of the hydraulic oil leak in
the steering gear. Therefore, it is necessary to encourage risk control makes the
operation of the steering gear does not affect all of the disadvantages that steering
gear becomes normal again. All that will be discussed in this paper the authors.
Keywords: Steering gear, hydraulic oil leak, the HAZOP method.
