Eastern Shipbuilding Group, Inc., Panama City, FL, recently delivered the 292 ft long Harvey Supporter, the first of three “Tiger Shark Class” Offshore Support Vessels for Harvey Gulf International Marine, LLC, New Orleans, LA. The vessel immediately went to work in the U.S. Gulf of Mexico under a long-term contract.
With an length of 292 feet, beam of 64 feet and depth of 24 feet 6 inches, the Harvey Supporter and its sister vessels, the Harvey Hauler and Harvey Champion, were designed by STX Marine Inc., which has offices in Houston, TX, and Vancouver, BC, Canada. The Harvey Hauler and Harvey Champion will be delivered in 2012 by Eastern Shipbuilding. The three “Tiger Shark Class” vessels are ABS classed, +A1, +AMS, + ACCU, +Circle E, Enviro +, Offshore Support Vessel and certified under SOLAS. ABS class includes +DPS-2 notation and FIFI 1.
The Harvey Supporter is believed to be the first first Offshore Support Vessel in the U.S. to be constructed to the rigid regulatory standards required for “ENVIRO+, Green Passport (GP)” certification by the American Bureau of Shipping (ABS), making it the most environmental friendly OSV in Gulf of Mexico. As such, the Harvey Supporter is in line with Harvey Gulf International Marine’s “Going Green” commitment. The ENVIRO+ notation means, among other things, that the vessel will have a trained environmental officer onboard at all times, implement required procedures to deal with ballast water, sewage and garbage management, keep a separate log of all relevant procedures and actions, with crew trained in those relevant procedures, comply with ISM and IMO requirements and have an approved contact with the marine casualty response center.
POWER BY CUMMINS
The Harvey Supporter is DP II SOLAS-class, with AC diesel-electric, twin Z-drive propulsion. Power and propulsion systems, controls, automation were supplied by Converteam, Inc. Propulsion power is supplied by four Cummins QSK60-DM 16-cylinder turbo-charged Tier II diesel generator engines that are rated 1,825 kW at 1,800 rev/min. Main propulsion is provided by two Schottel SRP 2020 FP Z-drives with nozzles rated at 2,500 kW at 1,025 rev/min each for a total of 6,704 hp. Schottel also supplied two STT 4 fixed-pitch tunnel thrusters rated at 1,180 kW at 1,170 rev/min each with direct coupled electric motors. The vessel is capable of top speeds in excess of 12 knots.
Total below-deck tankage capacities of the OSV include 275,000 gallons of fuel, 636,976 gallons of ballast water, 19,500 bbl of liquid mud, 14,350 cu. ft. of dry bulk mud, 1,700 bbl of methanol and 17,191 gallons of potable water.
Eastern Shipbuilding is also constructing a 302-foot-long light construction vessel Harvey Deep Sea for Harvey Gulf International Marine. The construction vessel will be ENVIRO, Green Passport (GP) certified. It will be equipped with an active heave-compensated 165-ton knuckle boom crane capable of lifting/setting 100 tons at depths up to 10,000 ft. The Harvey Deep Sea is scheduled for delivery in May 2013.
Meanwhile, Harvey Gulf International Marine is also breaking new technological ground with the construction of the first two LNG fuelled, U.S.-flag OSVs. Those vessels, being built by Trinity Offshore, New Orleans, LA, are also designed by STX Marine Inc. and will be ABS classed.
