Fourth GPA 670 PSV deliveredVessel & ROV News // January 19, 2006
Guido Perla, Chairman of Guido Perla and Associates (GPA), has announced the delivery of Hector, the fourth of 10 GPA 670 PSVs designed by the company for Bourbon Offshore.
Hector marks the last of four original vessels ordered, but with the offshore support vessel market booming and with the successful construction of Guido Perla and Associates’ design, Bourbon Offshore has expanded the GPA 670 building programme to a total of 10 vessels, which will be built at Zhejiang Shipbuilding in Ningbo, China.
“We established an office in China to oversee the construction of Bourbon’s GPA 670 Class of vessels. The expansion of the project to ten vessels, demonstrates the satisfaction of the vessels owner to continue the rejuvenation of its offshore fleet,” said Guido Perla. “The GPA series of platform support vessels for Rigdon Marine Corporation and Bourbon Offshore has established our company as one of the leading designers of platform support vessels in the world.”
The GPA 670 PSVs are 240ft, diesel-electric vessels, which are equipped with two stern-mounted Kawazaki KST-200 360 degree azimuthing Z-drive, fixed pitch, 1,200 rpm powered, full range variable speed motors.
A further enhancement to the diesel-electric drives is the technologically advanced dynamic positioning system and the vessel management system that provides total redundancy, which is required for the DP 2 certification. Consequently, if a vessel system fails, it can be bypassed without the loss of control during cargo operations or while maintaining position at an offshore facility.
The GPA 670 vessel is capable of carrying 9,005 cubic feet of bulk material and 6,868 barrels of liquid mud in self cleaning oval tanks. The vessels’ pumps deliver mud to a height of 197ft above water. The 80-PSI air compressors can also deliver 50 tonnes of dry cement or barite per hour to the same height.
