Tidewater Marine's New PSV's to Fit MacGregor Equipment

Cargotec has secured a comprehensive MacGregor offshore equipment contract for six platform supply vessels (PSVs) from Fujian Southeast Shipyard in China.

The vessels are being built for leading US offshore support vessel owner, Tidewater Marine LLC, and the equipment is scheduled for delivery between the first and fourth quarters of 2013.

Each 75m vessel will feature a MacGregor equipment package comprising a number of auxiliary winches such as anchor windlass, capstans and tugger winches, a single deck crane and a bulk handling system. "This type of cargo system has been well proven in service on over 60 ships and demonstrates Cargotec's ability to provide integrated ship-type solutions," says Francis Wong, Director of Sales and Marketing for Cargotec Marine's Offshore Segment. "An integrated approach to key equipment leads to optimised operations, allowing the vessel to function efficiently and safely, exactly as intended."

The PSVs will each have a total dry bulk capacity of 226m3, provided by four 56.5m3-capacity holds designed for cargo with a maximum specific gravity of 2.5.  "Our system is equipped with a programmable logic controller and a graphic operator interface for controlling and supervising the loading/ unloading process. This offers a high degree of automation and operational reliability; requiring minimal input from the operator.

"Instead of individual cabling, a Field BUS communication system is used between the controller and the control valves on the tanks and compressors. This makes the installation process easier and substantially quicker. A closed circuit dust handling system ensures pollution free operations, significantly reducing the environmental impact." he adds.
