Eastern Shipbuilding Group Inc. launched the HOS WARLAND on March 6 for Hornbeck Offshore Services LLC. The HOS WARLAND is the first of two 302’x76’x26’ multipurpose service vessels. The second HOSMPSV 310ES, the HOS WOODLAND, will be launched this summer.

The launch was held at Eastern’s Allanton, Fla., facility. The HOS WARLAND was the first ship christened using Eastern’s newly constructed 425’ rocker beam system installed on the northeast corner of Allanton’s 760’ launch basin. In addition, Eastern recently completed construction of a 300’x100’ new warehouse as part of the ongoing Allanton facility improvements.

Carl G. Annessa, Hornbeck’s executive vice president and chief operating officer praised the quality of workmanship, the ongoing vessel deliveries and the great operational performance of the eight HOSMAX 300/310-class platform supply vessels delivered. The remaining two HOSMAX 310s are being converted at Eastern’s outfitting facility to HOSMAX 310EQHs with enhanced capabilities to support the oil field specialty market, including helicopter landing decks and the flexibility to quickly add berthing for 50 to 130 people in five different habitability configurations. The HOSMAX 300/310-class was awarded a Significant Boats of 2014 award at the International WorkBoat Show in December.

The HOS WARLAND was the 11th Hornbeck vessel launched in the last 22 months at the Allanton facility.

Prior to the launch, Eastern’s President Brian D’Isernia commented about the vessel’s size, the onboard 250-MT subsea construction crane, the twin remote operated vehicle (ROV) capabilities and thru-hull moon pool features. He thanked all Eastern employees for their ongoing commitment delivering high quality vessels, on-time and on-budget, the continued growth of Eastern Shipbuilding and its long-term relationship with Hornbeck Offshore.

The two MPSVs will be U.S.-flagged, Jones Act-qualified, with 9,000 kW of installed AC diesel electric power, twin azimuthing Z-drive, DPS-2 MPSVs and designated HOSMPSV 310ES by Hornbeck. Each vessel is ABS-classed Hull and Machinery, Oceans Service and reviewed for the U.S. Coast Guard under the Alternate Compliance Program (ACP 2-95), SOLAS/IMO, ABS A1, AMS, with the following class notations: ACCU, DPS-2, UWILD, FFV-1, Circle E, Offshore Support Vessel (HNLS, HDC, HLC), GP, RRDA, HELIDK, ENVIRO, CRC, SPS (Special Purpose Ship).

These high-tech vessels feature four Caterpillar 3516C 16-cylinder turbocharged EPA Tier 3/IMO II diesel generator engines that are each rated 2,250 kW at 1,800 rpm. Main propulsion power will be provided by two GE Energy-furnished Hyundai 2,500-kW 690VAC motors driving two Schottel SRP 2020 FP Z-drives with nozzles rated at 2,500 kW at 1,025 rpm each for a total of 6,704 hp. Schottel also will provide three STT fixed pitch variable speed tunnel thrusters — two forward and one sternthruster — each rated at 880 kW, with direct coupled Hyundai 690VAC electric motors. A third bowthruster will be a swing down electric azimuthing variable speed thruster model TCNS 73CP rated at 880 kW provided by Rolls-Royce.

GE Energy Power Conversions provided the complete integrated diesel electric package, including the propulsion and thruster drives, four 2,250-kW generators, motors, control systems, Duplex Series C DP system, switchboards, motor control centers, automation and navigation/communication electronics. The vessels are designed with one Caterpillar C9 238 kW at 1,800 rpm emergency generator provided by Louisiana Cat.

Each vessel will have accommodations with 73 berths, galley and mess areas, a three-berth sick bay, a cinema/conference room with seating for 18 and a fully outfitted gym. The ROV control room, client operations center and a second conference room with seating for 12 is located on the 01 deck. The bridge will have a full complement of the latest electronics, communication and DPS-2 redundant operation stations. Each vessel shall be equipped with an octagonal shaped 21 meter diameter aluminum helideck manufactured by Helidex. The helideck is sized for a Sikorsky S-92 helicopter with a helicopter reception with seating for 18.

For heavy offshore subsea construction work, the vessel will be outfitted with a MacGregor HMC 4240 LKO 350-40 250-MT active heave compensated knuckle boom offshore crane with 3,700 meters of main wire. A second electro-hydraulic deck crane manufactured by North Pacific Crane Company will be installed. The North Pacific model 327 can lift a minimum of 1,500 lbs. at 27 ft. radius and shall be used to handle gangways and vessel stores.

Each vessel is designed with a 15’x18’ moon pool and hydro-acoustic hull penetrations. The vessel’s electrical system is arranged to power twin ROV/LARS systems. The vessels are fitted with an anti-heeling system and stability tanks to counteract the heeling moments associated with heavy crane lifts over the sides of the vessel.
