Subsea technology from Sonardyne that tracks the position of divers and remotely operated vehicles (ROVs) as they carry out surveys and inspections, has been selected by Vietnam-based Thien Nam Positioning JSC to supports its offshore activities in the region.
The Mini-Ranger 2 Ultra-Short BaseLine (USBL) acoustic tracking system, the first to be delivered into Vietnam, was supplied through Sonardyne’s subsidiary in Singapore. It has the capability to simultaneously and precisely track up to 10 underwater mobile targets and benefits from the same Wideband acoustic signal technology found in Sonardyne’s deep water USBL product family, but for significantly less cost.
Thien Nam Positioning conducts a wide range of geophysical surveys, pipeline and flowline installations, and maintenance operations in support of the country’s offshore oil and gas industry. Their divers and ROVs often work from vessels-of-opportunity, so survey equipment needs to be easy to install and easy to move from between vessels without affecting performance.
