Based on 10 years of field experience, we offer a complete and tailor-made service concept for oil lubricated stern tube seals and for CPP, bow thrusters, stern thrusters, and azimuth thrusters. For stern tube seals, we offer our own spare parts, compatible with the maker.

Technical support to give you options: We are available 24/7 to help you out with any technical questions you may have about the bow thruster, CPP, or stern tube, whether related to managing an immediate leakage issue, malfunctioning, planning of service/ repairs, the use of EALS, you name it.
