I’m not sure if I need a new liner for my shaft seals and want to avoid the expense of buying one that potentially I do not require. What are my options?

Unlike most OEM supply we accept returns of liners that you don’t need. There is a cost for this service but a small insurance to make sure you have contingency spares for whatever you may find in dry dock.

I have booked one of your engineers to come and service/calibrate my oil water separator monitor, what happens if it needs a factory repair?

Don’t worry, our engineers always carry a service exchange item, so we will have you up and running in no time. We will take your defective unit away, repair it and make available for the next vessel attendance.

I’m not sure what spares I need for my Thruster/CPP system/Shaft Seal etc.

We have extensive knowledge of propulsion equipment and know exactly what spares you need, in most cases. Just pass us the equipment details and we can provide you a detailed offer.
