Rigdon christens number three

Larry T. Rigdon, President and Chief Executive Officer of Rigdon Marine, announced today that the third of its ten platform supply vessels, M/V ROYAL, was recently christened and delivered for service.  The ROYAL was immediately deployed to begin work for a prominent oil and gas company in the Gulf of Mexico.

Mrs. Mathilde Currence, the wife of Richard Currence Jr., Vice President, Operations christened the ROYAL at Bender Shipbuilding & Repair Company., Inc. of Mobile, Alabama.

The "ROYAL" now joins the company's two other vessels, the BOURBON and the ORLEANS, which are also working for clients in the Gulf.  

"We are extremely pleased that drilling and seismic companies with operations in the Gulf of Mexico have vetted our vessels as being the most cost effective and operationally efficient ships available today," said Larry Rigdon. "Their acknowledgement of our vessel's increased payloads and speed with reduced fuel consumption has come in the form of contracts to employ these technologically advanced ships."

The Guido Perla and Associates designed (GPA 640) vessels are equipped with two stern-mounted Steerprop SP 20 azimuthing Z-drive units that are driven by two Alconza 2,100-hp variable-frequency AC electric motors, which provide the main propulsion.

A technologically advanced dynamic positioning system and vessel management system from Alstom Power Conversion provides the total system redundancy required for the DP-2 certification.

Consequently, if a vessel system fails, it can be bypassed without loss of control during cargo operations or while maintaining position at an offshore facility.

The cargo capacity of these vessels has also been increased due to the space saving diesel-electric engine room, which houses two 1,825 kW (2,500 hp) generators driven by Cummins QSK 60 engines and a third 910 kW (1,200 hp) generator driven by a Cummins KTA 38 engine. Furthermore, the fuel burn of the system has been rated at 230 gallons-per-hour (gph) at 13 knots when fully loaded, and only 88 gph at 10 knots. The diesel electric system provides a significant fuel savings over conventional, direct-drive, diesel propelled vessels.

The GPA 640 vessels have the capability to carry 7,133 cubic feet of bulk material and 5,100 barrels of liquid mud in self-cleaning oval tanks.  The vessels' two Mission Magnum 5"x4"x14' pumps deliver mud to a height of 196 feet above water. The two 80-PSI air compressors can also deliver 50 metric tons of dry cement or barite per hour to the same height.
