(Redirected from Darussalam class offshore patrol vessel)

The Darussalam-class offshore patrol vessel is a class of four offshore patrol vessels in Brunei Darussalam, constructed for the Royal Brunei Navy (RBN; Malay: Tentera Laut Diraja Brunei, TLDB).[1][2] They are the largest and most capable ships of the Royal Brunei Navy, and often participate in international naval exercises.[3] The lead ship in the class is KDB Darussalam (06).

Nakhoda Ragam contract dispute

edit

Prior to the Darussalam-class, three Nakhoda Ragam-class corvettes were built to order by BAE Systems Marine (now BAE Systems Maritime – Naval Ships) in the United Kingdom for the Royal Brunei Navy (RBN). The contract was awarded to GEC-Marconi in 1995, and the ships, a variant of the F2000 design, were launched in January 2001, June 2001 and June 2002, at the then BAE Systems Marine yard at Scotstoun, Glasgow in Scotland. Brunei refused to accept the three Nakhoda Ragam-class corvettes from BAE Systems. The contract dispute became subject to arbitration, and was ultimately settled in BAE System's favour. The vessels were handed over to Royal Brunei Technical Services (RBTS) in June 2007. In 2007, Brunei contracted the German Lürssen Werft shipyard to find a new customer for the three ships, and the ships were eventually purchased by Indonesia.

Offshore patrol vessel programme

edit

Brunei ordered the Darussalam-class offshore patrol vessels (OPV) from Lürssen Werft, the same company that Brunei contracted to sell the disputed Nakhoda Ragam-class corvettes. Keel laying for the first two vessels of this new class took place on 26 June 2009 at Lürssen shipyard in Germany. The first tranche of two vessels were launched 12 November 2010 and delivered to the Royal Brunei Navy in January 2011.[1][4][5] The first two were jointly commissioned by the Sultan of Brunei, Hassanal Bolkiah on 7 May 2011; 13 years ago (2011-05-07).[1] The second subsequent tranche of two vessels were delivered two phases, the final vessel arriving in Brunei in 2014.
