The state-of-the-art 57m Bhagwan Dryden was built in a collaboration between Bhagwan Marine and Neptune, with the hybrid catamaran boasting Neptune-supplied permanent air diving inspection and survey capabilities.

Other specs include 260 square metres of clear deck space, a DP2 dynamic positioning system, four-point mooring system, emergency hybrid capability, firefighting capabilities and a 21 tonne deck crane and 20t A frame.

The vessel is also built to operate in shallow waters, offering operational efficiencies at these depths, and is fitted out with a light work class Comanche remotely operated vehicle.

Dryden will be based in Australia working mainly on the North West Shelf and has already completed its first job, a mooring system inspection by the ROV for a key client.

More jobs are to come in October, when the vessel will begin operations for another key client as part of a five-year contract with a three-year extension.

Bhagwan Marine managing director Loui Kannikoski said the vessel would "without a doubt become our flagship vessel and cement our position as industry leaders in designing and delivering purpose-built vessels to our clients".

"The arrival of the Dryden in Australia reflects our successful collaboration with Bhagwan to jointly build a unique, purpose built vessel for projects and clients operating on the North West Shelf," Neptune CEO Robin King said.

"The combination of Bhagwan's vessel building expertise and our specialist services, offers clients a locally based complete solution for their inspection, repair and maintenance requirements."
