Marine Propulsion undertakes bow and stern thruster projects for superyachts and commercial vessels as part of scheduled refits, propulsion upgrades and planned maintenance programmes.

Engineering scope ranges from routine servicing through to complete overhauls, component replacement, reinstatement and commissioning. Projects are delivered as standalone engineering assignments or incorporated into larger refit programmes.


Engineering Scope

Bow and stern thruster capability includes:

  • Planned maintenance

  • Fault diagnosis

  • Complete overhauls

  • Thruster removal and reinstallation

  • Gearbox repairs

  • Bearing replacement

  • Seal replacement

  • Shaft repairs

  • Component inspection and measurement

  • System reassembly

  • Propulsion commissioning

  • Sea trial support

Engineering scope is tailored to the requirements of each vessel and project.

Overhaul & Reinstallation

Complete thruster overhauls frequently involve removal, inspection, component assessment, repair, reassembly and reinstatement as part of a larger engineering programme.

Marine Propulsion undertakes thruster projects requiring close coordination with other propulsion engineering activities, ensuring work is completed in line with the wider refit schedule.


Supporting Major Refit Programmes

Bow and stern thruster engineering is regularly incorporated into larger refit projects undertaken in New Zealand.

Engineering scope is developed alongside the vessel's overall maintenance programme, allowing components, specialist resources and workshop activities to be coordinated before work begins.

International project support is also available where specialist thruster engineering capability is required.

Common Project Questions

Planning a Refit in New Zealand?

Bow and stern thruster projects are often planned well before a vessel arrives in New Zealand.

Early engagement allows engineering scope, component procurement and project scheduling to be coordinated before refit work begins.
