State of the Art Features of the Harvey Gulf International

ENVIRO PLUS, GP, ABS Class Notation: In keeping with the Harvey Gulf International mission to provide our customers excellent marine service and value while causing no harm to people, assets or the environment, we have again taken the lead by building these new vessels to the rigid standards of the ABS “ENVIRO PLUS Notation”. These certified “GREEN” by design vessels will be classed by the ABS as having met all of the exacting requirements under their “ENVIRO PLUS Notation”. These Harvey Gulf vessels are the first vessels to be constructed to this ABS Regulatory Standard. Accordingly these vessels will comply with “Green Standards” resulting in an environmentally friendly ship that would be most welcomed by domestic and foreign customers. A synopsis of the advantage of the certified “ENVIRO Notation” on these vessels is as follows:

Intent is to reduce any adverse impact on the environment.

The vessel will have a trained environmental officer onboard at all times.

The vessel will implement required procedures to deal with ballast water, sewage and garbage management.

The vessel will keep a separate log of all relevant procedures and actions.

The vessel crew will be trained in all relevant procedures.

The vessel will comply with ISM and IMO requirements.

The vessel will have an approved contact with the marine casualty response center.

The vessel will be constructed of environmentally friendly materials.

The vessel will hold an ABS Class notation GP (Green Passport).

The vessel bridge layout will comply with the technologically advanced and safer electronics packages as required under ABS NBLES notation.

Ballast tanks will be constructed to minimize accumulation of sediment.

There will be no fuel oil against the skin of the vessel (IMO resolution 12A).

All fuel tanks will have high level alarms.

Approved oily bilge water separators will be in place.

Containments at fuel oil tank vents are enhanced.

Ballast and cargo tanks are segregated.

The vessel will be fitted with an IMO MEPC.159(55) approved sewage system to treat grey and black water and an approved management plan.

The vessel will have a garbage and ballast water management plan.

The vessel’s anti fouling paint will be biocide free.

All diesel engines will meet international and domestic emissions standards.

All refrigerant will be environmentally friendly and the vessel will have a refrigerant management plan.

Firefighting systems will not contain Halon or perflourcaborns.

The vessel will be fitted with a food stuff garbage grinder.

Next Generation “GREEN” Offshore Support Vessels Propulsion: Diesel electric propulsion, consisting of (4) 1825KW generators driving (2) 2500KW azimuthing main propulsion and (2) 1180KW bow thrusters. The (4) generators also provide ship’s service electrical power.

All (4) generators are “Tier II” compliant meeting all current U.S. and IMO emissions standards.

Diesel electric power configuration is the most efficient power system available for commercial marineapplications and significantly reduces fuel consumption and emissions footprint.

The diesel electric propulsion system can operate during low power demand periods with only (1) of the (4) 1825KW generators in operation reducing emissions, noise and vibration footprints while conserving fuel when such low power settings are acceptable.

Onboard Liquid Mud Circulation: The vessels capacity to transport much larger quantities of liquid mud (up to 19,500 bbls.) and the longer holding time onboard associated with deep water operations influenced Harvey Gulf to reengineer the traditional onboard liquid mud circulation system. Our state of the art liquid mud circulation system is the result of hundreds of hours of computational fluid dynamics (CFD) analysis using various liquid mud properties, flow rates and pressures, pump types and nozzle sizes and orientations and tank sizes to maximize circulation capability up to four weeks. Cargo Handling: Liquid and dry bulk muds, water and fuel cargoes are discharged via high capacity redundant pumps controlled electronically from a PLC at the pilothouse that includes mimic board displays with double check confirmation required to perform any function. All cargo values and actuators are high quality, reliable and manually operable as a backup. Propulsion and Bow Thrusters: The two (2) 1560 H.P. bow thrusters are fitted with the largest diameter skewed propellers available for the applica-tion so as to produce the most thrust as efficiently and quietly as is possible. The two (2) 3350 H.P. stern thrusters rotate 360° for maximum vessel control and are fitted with kort nozzles for maximum thrust in the dynamic positioning mode and maximum speed in the underway mode. Cargo Deck Safe Havens and Walkways: Four (4) covered “safe zones” are provided on the main deck outboard of the cargo rail for crew or industrial worker safety. A 5’ wide space is reserved port and starboard sides outboard of the cargo rail for a safe walkway for full length of the cargo deck. Off Ship Firefighting System: The vessel is fitted with two (2) separate firefighting monitors located atop the pilothouse, each connected to a 663 H.P. electric motor driving a pump and each capable of delivering 5284 gallons of water per minute. This system is ABS classed FIFI I.

Vessel Design:General design has been developed from decades of practical experience operating offshore vessels and under-standing the requirements of our customers and the safe and flexible vessel capabilities to meet or exceed those requirements. The vessels’ cargo delivery systems and crew accommodations are built upon an exceptionally stable platform particularly suitable for the long distance, all weather operational requirements associated with deep water operations. The vessels cargo systems can deliver over 5,600 dead weight tons of cargo at loadline to these remote locations at approximately 12.5 knots speed.
