Rolls-Royce Extends TBO Intervals of MTU Series 4000 Engines for Commercial Marine Application

Tarih: Issue 111 - December 2021

Rolls-Royce is introducing significantly extended engine running times of up to 96,000 hours between overhauls (TBO) for the latest generation of its MTU Series 4000 engines for commercial marine. In general, all marine engines of the latest generation of MTU Series 4000 can now run for up to 25 years before they need a major overhaul, depending on the duration and intensity of use. That is seven years more between overhauls than previously recommended. 

The company thus not only makes an important contribution to sustainability and resource conservation but also allows its customers to significantly reduce operating costs as well as enabling better plannability and higher availability of tugs, ferries, and workboats. This is made possible by the almost legendary reliability and robustness that Series 4000 engines have been demonstrating for 25 years and Big Data analysis of tens of thousands of real engine data sets, which enables Rolls-Royce to accurately predict engine and component running times. The new TBO intervals and maintenance schedules, which Rolls-Royce will present for the first time at the International Workboat Show in New Orleans, apply to new engines of the type 4000 M05.
