The details were released in the July 2015 edition of a quarterly staff newsletter published by the TNI-AL's communications office, Cakrawala .
The capabilities will include an autonomous underwater vehicle (AUV) and a remotely operated vehicle (ROV) able to collect samples from the ocean floor.
Rigel is the first of two 60 m OSVs ordered from French shipbuilder OCEA SA under a USD100 million contract signed in October 2013.
The OSVs are powered by two MTU 8V 4000 M53 engines driving two fixed-pitch propellers. The vessels have a top speed of 14 kt and a standard range of 4,400 n miles at 12 kt, and can operate in up to Sea State Six. They can accommodate a crew of 30 and 16 mission personnel at sea for 20 days. The OSVs carry one Rheinmetall 20 mm main gun and two stern-facing 12.7 mm machine guns.
Survey equipment includes Kongsberg's EA 600 single-beam echo sounder, and the company's EM 2040 and EM 302 multibeam systems. The survey suite enables detection of underwater objects and keel clearance (among other hydrographic functions) at the TNI-AL's naval bases.
The vessel is also equipped with Kongsberg GeoAcoustics' Sonar 2094 side-scan sonar system for underwater mapping.
The AUV capability is provided by Kongsberg Maritime's Hugin 1000, which is capable of performing high-speed survey missions at depths of up to 1,000 m. Rigel is equipped with one Ocean Modules' V8 ROV, which is fitted with a manipulator arm that can collect underwater samples for analysis.
IHS Jane's understands that Rigel is currently based with the TNI-AL's Military Sealift Command (KOLINLAMIL) in Tanjung Priok, North Jakarta. The vessel is scheduled to be joined by sister ship KRI Spica (934) in September 2015.
The Indonesian Navy's first new oceanographic offshore support vessel KRI Rigel (933) arrived at Jakarta International Pier Container Terminal (JICT) 2.
