More details on Rigdon's First and TenVessel & ROV News // August 24, 2007
First and Ten - first of Rigdon Marine's new GPA 654s PSVs.
First and Ten is a diesel electric vessell, designed by Guido Perla.
As previously highlighted in Offshore Shipping Online, Rigdon Marine in the US has recently taken delivery of the first of 10 new GPA 654 PSVs, the first vessel being appropriately named First and Ten. The vessel was delivered from Bollinger Shipyards in Louisiana. Another 22 of the vessels of the same 190ft design are on order by Bourbon Offshore from a Chinese yard.
As with earlier Guido Perla-designed supply vessels, the diesel-electric propulsion power in these vessels is being supplied by Cummins Mid-South LLC of Kenner Louisiana.
For these vessels the diesel electric package consist of two Cummins KTA-50DM1-powered 1,235 KW and one Cummins KTA-19DM1-powered 425 KW main propulsion generators and one 6BTA5.9G-85 KW SOLAS emergency standby generator.
First and Ten is a 190ft x 46ft x 18ft PSV with two azimuthing vertical electric drives and one fixed electric L-Drive aft as well as two large tunnel thrusters forward.
The redundancy of propulsion systems on these vessels earns them DP 2 status.
They are fully diesel electric with Silicon Controlled Rectified (SCR) DC drives.
A unique feature of the design has the engine room at the first deck level.
Not only does this allow for more bulk storage capability under the main deck but it also allows for ease of maintenance and repair by vendors such as Cummins and AVK.
The engines are connected to the vessel management system by means of a Mod Bus arrangement supplied by Cummins Mid-South using Auto Maskin panels. They tier into a Techsol vessel management system and a Frank L Beier DP system.
Electric Power Design of Houston Texas and Yangzhoa China provided the entire vessel power management system including all motor control centers, SCR system and the actual drive motors themselves.
Karl Senner of Kenner, Louisiana supplied the Steer Prop steerable propeller systems.
All vendors will remain constant on all 32 vessels to be constructed both in the US and China.
The vessels were designed under the guidance of Guido Perla and Associates.
The Rigdon 4000 PSVs have capacity for up to 4,000 barrels of liquid mud in an independent and fully segregated, self-cleaning oval tank system.
The design allows them to deliver 100 per cent of their mud cargo to an offshore rig while reducing the client’s expense of tank cleaning.
Since her delivery in early August the First and Ten has been working under charter in the Gulf of Mexico out of Port Fouchon, Louisiana.
The balance of the ten vessels from Bollinger will deliver throughout 2007 and 2008.
