VESSELSLEEVAC Shipyards Jennings LLC has signed contracts with Hornbeck Offshore Services, LLC for the construction of two (2) STX Marine SV 310 Multi-Purpose Supply Ves- sels; 302? x 76? x 26?, 12,070 BHP diesel electric powered MPSV?s. The boats will be the twenty-third and twenty- fourth vessels to be built by LEEVAC for Hornbeck. The SV 310 is a complex vessel with unique characteristics integrat- ed into the design by Hornbeck Offshore to meet subsea in- spection, repair and maintenance (IMR) support and heavy lift requirements. The vessels will be out tted with a 250 ton crane provided by Cargotech, and will be powered by four (4) Caterpillar Model 3516C Tier 3 IMO II Marine variable speed diesel propulsion generator sets rated at 2250 kw each. The propulsion drives and thrusters are being provided by Schottel. GE Power Conversion will provide the integrated electrical system, power management, vessel control, DP-2 systems, machinery alarms, power and propulsion systems. Marine Interior Systems has been selected for the joiner work and Marine Aluminum will be providing the helideck system rated for a Sikorsky S-92 helicopter. Built to ABS, USGC and SOLAS classi cations, the vessel will meet ABS A1 Offshore Support Vessel (FFV-1) notation for off ship  re- ghting capabilities and SPS (Special Purpose Ship). The Port of Houston Authority this month received the  rst of three high-performance  reboats to replace the current  eet. The new  reboats will equip the Port Authority?s  re-  ghting team with the most sophisticated  eet in the world. The new Firestorm 70 is a state-of-the-art command center and high speed response vessel. Built by MetalCraft Marine, each  reboat has powerful quad diesel inboard engines to pro- pel the vessel at a swift 45 knots top speed; critical when pro- viding  re protection for the 25-mile long Port of Houston. The new  reboats are maneuverable, make quick stops and change direction within three boat lengths. Part  rehouse, part  reboat, the vessel enables the crew to stay on station for extended periods. The cabin includes a primary care berth with four secondary berths in the cuddy. Portable berths can be positioned to handle the injured at an incident. Four  re-  ghting pumps can produce  ow meter results of 13,600 gallons per minute (GPM) at 150 pounds per square inch (PSI) and 17,000 GPM at 130 PSI and stream up to 450 feet with a roof mounted Stang monitor. As a shore hydrant, the FireStorm 70 can pump an impressive 7,000 GPM at 70 PSI through 1000 feet of hose from a 5? Storz outlet before stag- ing pumps are required. Each  reboat is 70?10? long with a breadth of 22?10? and a draft of 34 inches.
