MAN Diesel & Turbo warns of faulty accumulator parts

MAN Diesel & Turbo has issued product safety warnings about faulty Total Solutions & Power (TSP) accumulators with the 10L design, fitted to the hydraulic system on MAN B&W two-stroke diesel ME-type engines with 300-bar working pressure.

In a circular, MAN said the part has suffered from breakage due to a failure in the thread design, causing parts of the accumulator body to be ejected into the engine room, causing damage to the engine itself.

The faulty component constitutes what MAN called a “serious potential threat to property and persons and may potentially even result in bodily injuries and/or fatal casualties”.

What is more, tests by TSP have shown that the protective guard solution for the 10L-design accumulator is not an effective protection measure. TSP has circulated an action plan on how to exchange affected 10L accumulators with a new improved version. The plan can be read here.

“Based on the information provided by TSP, we therefore strongly recommend to inspect the accumulators installed on your engines at the very first opportunity possible in order to verify whether and to what extent your engines have accumulators installed that are made by TSP,” MAN advised.

MAN said accumulators fitted to its Alpha Lubricator system and to the MC-type engines are not affected.
