Retrofit of a steering system with an obsolete drive
Modernisation of the hydraulic steering drive, keeping the vessel's original structural interfaces.
Execution
The sequence applied and the engineering decisions taken
The order below reproduces how the work was actually carried out, including the points where the condition found required a change of scope.
- Full survey of the existing interfaces: fixings, strokes, loads and hydraulic connection points.
- Design of the new drive around current-production components with replacements available in Brazil.
- Manufacture of bases, supports and mechanical adaptors to reuse the original structural fixings.
- Replacement of the power unit and the control block.
- Installation, hydraulic interconnection and flushing of the lines.
- Commissioning with response time and rudder angle verified to port and starboard.
Comparison
Condition before and after the intervention
Drag the slider to switch between the two recorded conditions.
- Before
- Drive built on components out of production, with spares dependent on imports.
- After
- Modernised drive on locally available components, using the original structural interfaces.
Result
What the intervention delivered
The vessel now runs on components with replacements available in Brazil, removing the dependence on imports. No structural alteration to the engine room was needed, and the response times met the design requirement.
