STUART, Florida – CSA Ocean Sciences Inc. (CSA) has added the R/V Dolphin to its coastal survey fleet.

The 15-m (49-ft) multi-purpose vessel has been specially configured to support marine geophysical surveys.

The R/V Dolphin’s layout includes a large aft working deck, a raised wheelhouse with 360° viewing windows, and a multi-use salon area below deck.

The vessel is powered by twin Detroit Diesel 8-71 motors and a 20-kW generator. On deck are two high speed integrated research winches, each with six-pass slip rings to support custom instrument interfacing. Each winch is capable up to 1,500 lbs pull with electronic controls for local or remote operation.

A 1,500 safe working load articulating A-frame is located on the vessel’s transom. The legs are spaced 3 m (10 ft) wide for the launch and recovery of large towed instruments. Two modular J-frames are incorporated on the outboard side of each cross member to provide additional tow points and wider spread for the simultaneous deployment of towed gear.

The R/V Dolphin is currently configured to simultaneously tow a transverse marine gradiometer and side-scan sonar, with an additional magnetometer concurrently operating multi-beam, single-beam, and sub-bottom profilers, and an ultra-short baseline transceiver.

Kevin Peterson, CEO of CSA, said: “This is a rugged, long range vessel that has been designed and outfitted with the latest technology and equipment to ensure safe and reliable operations in water depths ranging from hundreds of meters to shallow nearshore sites.”
