The GPA 640 PSV, measuring 64 meters in length and providing accommodations for 22 crew members, is equipped with environmentally friendly diesel-electric propulsion, resulting in lower fuel consumption than direct drive systems, thus producing far less pollution.
The vessel provides liquid mud tank capacities and delivery capabilities typically found only in much larger vessels. Oval liquid mud tanks with a self-cleaning system provide maximum circulation and are more cost effective to clean than traditional square tanks. The deck equipment may include an optional 1.8 mt @ 10 m electro-hydraulic telescopic boom deck cargo crane. The DPS-2 and FFV-1 certified GPA 640 PSV is designed to provide exceptional maneuverability and maintain a speed of 15 knots at loadline, which is up to 30% faster than most existing vessels of equal size.
Ten of the GPA 640 PSVs were delivered by Bender Shipbuilding and Repair in Mobile, Alabama to Rigdon Marine in 2005, and are currently serving the Gulf of Mexico shelf and deepwater production markets. Two GPA 640 PSVs were ordered in September 2006 by Trico Marine and were both delivered by Bender Shipbuilding and Repair in 2008.

The GPA 654 PSV, measuring 54 meters in length and providing accommodations for 12 crew members, is the smallest of the GPA Platform Support Vessel series and is equipped with environmentally friendly diesel-electric propulsion, resulting in lower fuel consumption than direct drive systems, thus producing far less pollution. The vessel provides liquid mud tank capacities and delivery capabilities typically found only in much larger vessels. Oval liquid mud tanks with a self-cleaning system provide maximum circulation and are more cost effective to clean than traditional square tanks.
The deck equipment may include an optional 1.8 mt @ 10 m electro-hydraulic telescopic boom deck cargo crane. The DPS-2 and FFV-1 certified GPA 654 PSV is designed to provide exceptional maneuverability and maintain a speed of 13 knots at loadline, which is up to 30% faster than most existing vessels of equal size. Currently, 24 GPA 654 PSVs are on order and currently under construction at Dayang Shipyard in China for Bourbon Offshore while ten GPA 654 PSVs are under construction for Rigdon Marine at Bender Shipbuilding in Louisiana with the first launched in spring 2007.

The GPA 670 MKII Special Products, measuring 73 meters in length and providing accommodations for 23 crew members, is equipped with environmentally friendly diesel-electric propulsion, resulting in lower fuel consumption than direct drive systems, thus producing far less pollution. The main difference between this vessel and the original GPA 670 PSV is its capability to carry 174 m³ in specially designed tanks located at the aft end of the vessel that can carry special products, such as methanol.
The vessel provides liquid mud tank capacities and delivery capabilities typically found only in much larger vessels. Oval liquid mud tanks with a self-cleaning system provide maximum circulation and are more cost effective to clean than traditional square tanks. The deck equipment includes an electro-hydraulic telescopic boom 2 mt @ 16 m deck cargo crane. The DPS-2 and FFV-1 certified vessel is designed to provide exceptional maneuverability and maintain a speed of 15 knots at loadline, which is up to 30% faster than most existing vessels of equal size
The GPA 670 PSV MKII Special Products is very similar to the original GPA 670 PSV design but it provides the possibility to carry up to 167 m³ special products, such as methanol, in specially designed tanks located in the aft end of the vessel.

The GPA 670 MKII ROV, measuring 73 meters in length and providing accommodations for 40 crew members, is equipped with environmentally friendly diesel-electric propulsion, resulting in lower fuel consumption than direct drive systems, thus producing far less pollution. The vessel provides liquid mud tank capacities and delivery capabilities typically found only in much larger vessels. Oval liquid mud tanks with a self-cleaning system provide maximum circulation and are more cost effective to clean than traditional square tanks.
The deck equipment includes a heave compensated 9 mt @ 18.5 m deck cargo crane and a 150 mt A-Frame. The DPS-2 and FFV-1 certified vessel is designed to provide exceptional maneuverability and maintain a speed of 13 knots at loadline, which is up to 30% faster than most existing vessels of equal size. Currently, four GPA 670 MKII ROVs are under construction at Zhejiang Shipyard for Bourbon Offshore with an expected delivery date for the last one in September 2009.

The GPA 696 IMR, measuring 100 meters in overall length and 21 meters in maximum breadth, are currently the largest in the GPA-designed PSV fleet. The multipurpose vessels will be equipped with two deck cranes and a helideck designed for a Super Puma Helicopter EC225.
The configuration of the environmentally friendly diesel-electric propulsion system of the Fifi-1 certified GPA 696 IMR, which will be equipped with Z-Drives, tunnel bow thrusters and azimuthing bow thrusters delivered by Schottel, creates fully redundant engine rooms and thruster compartments and also results in reduced maintenance cost and improved station-keeping at offshore installations, and significantly increases crewmember safety, which has been GPA standard for all the GPA 600 and 200 series of offshore support vessels.
In February of 2008, GPA signed a contract with Bourbon Offshore to build ten of the GPA 696 IMR vessels at Zhejiang Shipyard in China.
