HTMS Krabi (OPV-551) is an offshore patrol vessel (OPV) of the Royal Thai Navy. She is a modified River-class patrol vessel, and was built by Mahidol Adulyadej Naval Dockyard, with design and technology transfer support from BAE Systems Surface Ships.[3] Additional construction took place at the Royal Thai Navy Mahidol Dockyard in Sattahip.[4]
The contract for the construction of Krabi was signed in June 2009,[3] and construction began in August 2010.[5] Krabi was launched on 3 December 2011 in a ceremony attended by Princess Maha Chakri Sirindhorn.[5] After launch, she began outfitting, and entered service in 2013.[4][5] The Thai Navy plans to use Krabi to patrol Thailand's Economic Exclusion Zone (EEZ), as well as for fishery and natural resource protection and disaster relief.[5]
Krabi is 91 meters in length, and carries an Oto Melara 76 mm main gun and two MSI 30mm secondary guns for primary defense, as well as machine guns.[3][4] It is able to operate an AgustaWestland AW139 helicopter flying from a 20 metres (66 ft) flight deck.[3] Her top speed is expected to be over 25 knots (46 km/h; 29 mph),[4] and she is powered by two MAN 16v 28/33D diesel engines, making about 7.2 megawatts (9,700 hp).[3] She is equipped with a Thales Variant surveillance radar, a Thales Lirod Mk2 fire control radar and the Thales Tacticos combat management system.
