Eastern Shipbuilding Group, Inc. launched the HOS Warland (Hull 241) on Friday March 6, 2015 for Hornbeck Offshore Services, LLC. The HOS Warland is Eastern’s first of two 302’x76’x26’ multipurpose service vessels (MPSV) launched with the Hornbeck designation HOSMPSV 310ES. The second vessel, the HOS Woodland (Hull 242), will launch this summer.
The launching event was held at Eastern’s Allanton facility with hundreds of Eastern employees and guests in attendance. The HOS Warland was the first ship to christen 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.
Attending from Hornbeck Offshore Services was Carl G. Annessa, executive vice president and chief operating officer, who spoke about the long term commitment, partnership and future of the two companies: “Hornbeck Offshore Services has come to consider the men and women of the Eastern Shipbuilding Group as the best shipbuilders that we’ve enjoyed the pleasure of working with,” he said.
Annessa 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 two remaining HOSMAX 310’s are being converted at Eastern’s outfitting facility to the HOSMAX 310EQH configuration, 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 persons in five different habitability configurations.
Also attending the launch ceremony was Bill Krewsky, director of engineering and project management, manager of projects Jim O’Kane, project manager Jim Clendenon and operations personnel of the Hornbeck Team, who witnessed the 11th Hornbeck vessel launched within 22 months at Eastern’s Allanton facility.
Operations manager, Captain George McCoy, an 18-year employee of Hornbeck Offshore, and his wife Joyce were the Hornbeck honorees who christened the vessel. Deacon Earl Mirus of Saint John’s Catholic Church of Panama City, Florida, performed the blessing of the vessel.
Prior to the launch, Eastern’s president Brian D’Isernia said a few words about the vessel’s size, the onboard 250MT subsea construction crane, the twin remote operated vehicle (ROV) capabilities and thru-hull moon pool features. He thanked all his 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 and the offshore marine industry.
