Tidewater plans series of diesel electric PSVs

Tidewater Marine is planning to construct a series of 12 diesel-electric platform supply vessels (PSVs) based a design from a Polish naval architectural firm.

The series is based on the MMC 887 PSV design from MMC Ship Design & Marine Consulting Ltd. The PSVs are being built in China at Fujian Mawei Shipbuilding Ltd. The offshore service vessels will have an overall length of 87.2 m, beam of 18.8 m, depth of 7.4 m, scantling draft of 6.2 m and design draft of 5.9 m. Each vessel will have a fresh water capacity of 660 cu.m, ballast water/drilling water 1,800 cu.m, fuel oil capacity of 945 cu.m, lquid mud capacity of 2,491 cu.m, and a dry bulk capacity of 400 cu.m.

The aft work deck area will be 1,000 m2, with a deck cargo capacity of 1,000 tonnes.

Prime movers will be four 2,145 hp diesel engines. The PSV's will have a speed of 14.2 knots.

Tidewater says the propulsion choice was specified as it offers greater operational flexibility and efficiency. The flexibility of diesel-electric propulsion allows for a one or more of the engines to be shut down when full power is not required.

The first of the MMC-887 PSVs will be delivered in the fourth quarter of 2010. Each of the Vanuatu-flagged vessels will be classed by ABS as +A1 (E) Offshore Support Vessel, +AMS, +DPS 2 and +FFV Class 1.
