Indonesian Ministry of Defence Delegation Visited DOEN Waterjet Engine Factory in Australia

Doen WaterJets was a pleasure to host a delegation from the Indonesian Ministry of Defence (MOD) at their company. The company is supplying a DJ450B-DT waterjet (impeller dia. 1145mm) to PT Palindo Marine, which is commissioned by the MOD to design and construct the new generation 68m fast attack craft for the Indonesian Navy (TNI Al). The equipment, configured as a booster jet will be coupled to MAN Energy Solutions’ 20V175D-ML diesel, rated at 4400kW. The intake tunnel is fabricated from the hull matching steel plates and is tailored to suit the contours at the bottom of the boat, further simplifying welding/integrating it into the hull. And the entire pump assembly, including the impeller casing and the discharge nozzle, is made of stainless steel, underpinning best-in-class durability and sustained performance.

The DJ450B-DT is Doen’s exclusive Direct Thrust (DT) variant – which is no coincidence as all our waterjet products in service by the Indonesian Navy are the same type and the Navy is extremely satisfied with the extra level of reliability and simplicity associated with DT waterjets. The MOD’s delegation successfully concluded the Pre Shipment Inspection (PSI) on DJ450B-DT, which was significantly facilitated/expedited by the fact that

  • Doen WaterJets is an hashtag#ISO9001 company and has stringent quality assurance procedures in place.
  • DJ450B-DT is built to the requirements of the Bureau Veritas Group (BV) classification society.

The Indonesian Navy embarked on the steel-cutting ceremony for its new generation 68m fast attack craft variant at the Palindo Marine shipyard in Batam on March 25. This milestone event marks the commencement of construction for two vessels based on the design of Large Patrol Craft (LPC) sourced from Turkiye’s TAIS Shipyards, a deal secured during the Indo-Defence Expo 2022. The vessel boasts a beam of 9.45 meters and a draft of 2.55 meters, with an estimated displacement of around 660 tonnes. Powered by two diesel engines, the vessel can attain a maximum speed of 27 knots. Moreover, at its cruise speed of 19 knots, the vessel exhibits an impressive maximum range of 1,500 nautical miles or a 7-day endurance.

Tailored to meet the specific operational requirements of the Indonesian Navy, notable adaptations have been made to the original LPC blueprint. While the original design featured a twin-barrel 40 mm cannon at the aft, the Indonesian version has opted for a Rigid Hull Inflatable Boat (RHIB) station in its place. Additionally, two 12.7 mm heavy machine gun stations have been incorporated atop the ship’s rear superstructure. Although the 2×2 launchers for the Atmaca anti-ship missiles remain unchanged, the positioning of the anti-submarine rocket launcher has been relocated to the top of the ship’s bridge. Indonesia is set to integrate advanced naval technologies supplied by Turkish defense firm Havelsan.
