Diesel/Dual Fuel Engine Service
Riding Crews – Goltens capabilities as an expert in comprehensive engine services are unquestioned. With 8 decades as an engine specialist, Goltens capabilities cover virtually all makes and models of larger bore 4 stroke and 2 stroke engines found in the marine market. Goltens engine service model is based on deploying highly trained teams or riding crews to effect the engine repair either alongside or on voyage to minimize the impact on schedules. Our teams travel will all tools required to overhaul components onboard negating the requirement to send components ashore.
Swing Set Model – To maximize efficiency and minimize downtime associated with overhauls, Goltens has implemented a “swing set” approach with certain operators. With this alternate approach to onboard overhaul, the owner secures an extra set of components that can be fully overhauled in Goltens’ workshop between overhauls and delivered onboard for the next scheduled maintenance. This limits onboard attendance, shortens overhaul/downtime periods and controls costs.
Major Casualties – Beyond routine maintenance, Goltens is known for its ability to restore engines from catastrophic casualties. Crankshaft, block and bedplate replacements are routine repair operations for Goltens and are done in the safest, most professional manner in the market.
