PREMIUM: Indonesian MCMVs make sweeping progress

Two new minehunters for Indonesia will be powered by MAN engines and an electric hybrid propulsion system.

Two mine countermeasures vessels (MCMV) for the Indonesian Navy are being constructed in Lemwerder, Germany by the shipbuilder Abeking & Rasmussen.

A $204 million contract for the 62m-long ships was concluded in January 2019, and a steel-cutting ceremony was held on 26 November 2020. Featuring a non-magnetic steel hull, the MCMV design is based on the Frankenthal class operated by the German Navy.

Once commissioned, they will allow retirement of the navy’s two Pulau Rengat-class minehunters built in the Netherlands. These entered service in March 1988, so they are already long in the tooth.

In the mid-1990s, Indonesia also purchased Pulau Rote-class MCMVs from East Germany, and six remain in service in the minesweeping role.

It is unknown what sensors the new MCMVs will have, but a sonar will be supplemented by remotely operated vehicles. The German Navy utilises a DSQS-11A mine-hunting sonar, Seafox I and Seafox C AUVs.

The MCMVs will be powered by a MAN hybrid propulsion package. According to a MAN Energy Solutions press release issued on 10 February, the vessels have two MAN 12V175D-MM engines with an output of 2,220kW at 1,900rpm; a MAN Alpha CPP twin-screw propeller that incorporates an Alphatronic 3000 propulsion control system; and an AKA hybrid PTI pure electric system for silent operation whilst hunting for mines.
