Driveline Engineering for Superyachts & Commercial Vessels

Complete driveline projects require more than replacing individual components. Every engineering decision affects the performance of the propulsion system as a whole.

Marine Propulsion undertakes complete driveline engineering projects for superyachts and commercial vessels, supporting scheduled maintenance, propulsion upgrades, major refits and complete driveline replacement programmes.

Project scope is developed in consultation with captains, chief engineers, yacht management companies, naval architects and boatyards well before engineering work begins.

Engineering Scope

Driveline engineering capability includes:

  • Complete driveline replacement

  • Propulsion system upgrades

  • New driveline installations

  • Gearbox installation and replacement

  • Shaft removal and installation

  • Stern tube servicing and repairs

  • Bearing replacement

  • Coupling installation and alignment

  • Propeller shaft repairs

  • Driveline fault diagnosis

  • Vibration investigations

  • Propulsion system commissioning

  • Sea trial support

Engineering scope may form part of a larger refit programme or be delivered as a standalone project.

Engineering Approach

Every driveline project begins with an assessment of the propulsion system as a whole.

Engine, gearbox, shafting, bearings, stern tube and propeller are assessed together before engineering recommendations are made. This allows underlying issues to be identified early and ensures engineering decisions are made within the context of the complete propulsion system rather than a single failed component.

The result is an engineering solution aligned with the vessel's operating requirements and the wider project scope.

Typical Project Involvement

Driveline engineering is regularly undertaken as part of:

  • Complete propulsion replacement programmes

  • Scheduled superyacht refits

  • Commercial vessel maintenance programmes

  • Gearbox replacement projects

  • Shafting replacement

  • Stern tube replacement

  • Propulsion commissioning

  • Vibration investigations

Many of these projects begin well before the vessel arrives in New Zealand, allowing engineering scope, procurement and scheduling to be coordinated in advance.

Common Project Questions

  • Complete driveline projects are commonly planned six to eighteen months before a vessel arrives in New Zealand. Early engagement allows engineering scope, procurement and scheduling to be coordinated before refit work begins.

  • Yes. Complete driveline replacement projects are undertaken from initial engineering review through to installation, commissioning and sea trials.

  • Yes. Vibration investigations form part of Marine Propulsion's broader driveline engineering capability. Assessment extends across the complete propulsion system to determine the underlying engineering cause before remedial work is recommended.

  • Yes. Marine Propulsion is regularly engaged as the specialist propulsion engineering contractor within larger refit and maintenance programmes, delivering defined engineering scope alongside the wider project team.

  • Yes. While many projects are completed during scheduled refits in New Zealand, international project support is also available where specialist propulsion engineering expertise is required.
