02To Our Customers

We recommend managing running hours of components.

Critical parts are subject to defined life span, wear limits, tolerance, lift, leak amount, etc, and the management of maintenance history helps prevent issues proactively.
When requesting maintenece and repair for parts, we may ask for confirmation of runnning hours. Your cooperation in this matter is greatly appreciated.

Our inspection reports note running hours informed by the customer, which helps in the management of component maintenance history.

We recommend using manufacturer's genuine parts.

If unauthorized or modified parts are installed, it will be impossible for us to perform repairs.
We would ask for your intention to replace with the original part or to continue usage.
We would recommend to use genuine parts and keep proper maintenance interval to keep reliability of machinery and prevent from any troubles.

We recommend following the specified maintenance intervals.

Regular maintenance based on specific interval by manufacturer helps user keeping machinery in good order.

We recommend maintenance before unexpected trouble occurs.

Sludge accumulation or minor damage may progress without any sign, even when the machinery works well.
Performing maintenance in advance, while the system is functioning properly, can prevent unexpected issues and save costs.

For NIMONIC and DURA exhaust valve spindles, welding repair will not be possible in case burn-out amount exceeds the limit.
Welding repair within the limit will help to reduce operation cost and contribute to extend lifetime of the parts.

Crew burden reduction

Our service will contribute to make ship crew work load lower, or just manage maintenance history.
