Sea trials success [INDODEF16-D1]

01 November 2016

The future KRI Raden Eddy Martadinata, the first of two SIGMA 10514 Perusak Kawal Rudal (PKR) frigates on order for the Indonesian Navy (TNI-AL), has successfully completed sea trials ahead of delivery in early 2017.

Damen Schelde Naval Shipbuilding (DSNS) – as prime contractor – signed a contract in December 2012 with the Indonesian Ministry of Defence for the first PKR. An option for the second vessel was exercised in mid-2013.

Construction of the ships has been shared between the Vlissingen, Netherlands, facility of DSNS and the PT PAL shipyard in Surabaya. The 105m, 2,365-tonne PKR frigates are the largest SIGMA variants built to date.

Concurrent collaborative modular build has significantly reduced construction time, with manufacture activities for the ship only beginning in January 2014. “The success of the programme rested on the two yards working together with the end client operating almost as a single unit,” said DSNS in a statement. “The strong relationship also allowed the technology transfer programme to proceed smoothly, both in Indonesia and in the Netherlands.”

Each vessel is made up of six modules. For the first ship, four of these were built by PT PAL; the remaining two, comprising the bridge/ command centre and the main machinery space, were built, outfitted and fully tested by DSNS in Vlissingen before being shipped for final assembly at PT PAL.

Prior to the start of sea trials, the ship completed seven days of basin trials to ensure that the propulsion and safety systems were fully operational, before commencing passage from the PT PAL shipyard in Surabaya to the open waters of the Java Sea. The ship then completed a two-week period of sea trials during late August/early September, including tests of a weapon, sensor and command systems. Noise measurements and cavitation observations were also performed.

The main sea trials period concluded on 7 September. In a statement, DSNS said the trials were successful “with almost all the systems passing their assessments first time around”.

Minor changes, including modifications to accommodation, were implemented prior to three days of final testing at the end of September.

Raden Eddy Martadinata is on schedule for delivery at the end of January 2017 following the completion of three months of crew training.

Work continues at Vlissingen and Surabaya on the build of the second PKR vessel, to be named Gusti Ngurah Rai. Delivery is scheduled for October 2017.
