Planning Ahead with our Planned Service Agreement
Unexpected repair costs and unplanned downtime can quickly impact schedules and profitability. A Planned Service Agreement (PSA) gives you a structured maintenance programme built around your vessel’s equipment, operational requirements and budget, with clear service support and predictable planning.
- Predictability: Payments spread across the duration of the contract.
- Guaranteed: Service engineer availability, often up to 50% lower in cost than the OEM.
- Assurance: Agreed spare parts availability to support operational certainty.
