Marine diesel engine service & repairs in Sydney

Sydney-based onboard and workshop support for low, medium and high-speed marine diesel engines—from fault-finding and urgent repairs to planned maintenance, major overhauls and return to service across NSW, Australia and the Pacific.

Marine diesel support in Sydney and where the vessel needs it

From its Rozelle base in Sydney, Nauti Diesel supports commercial vessels, workboats, passenger vessels and private operators alongside, at anchor, in dry dock and in the workshop. The work is scoped around the engine condition, operating requirements, available service history, access and the time available to return the vessel to service.
