Second JHSV Completes Builder's Trials
Joint High Speed Vessel (JHSV) 2, the future 'USNS Choctaw County', successfully comes through Austal USA's sea trials. Builder's trials are a significant step in the construction and delivery of a ship to the fleet and are the first opportunity to operate the ship underway and test overall system performance prior to demonstration to the Navy's Board of Inspection and Survey (INSURV). "JHSV 2 is the second ship in this class to go through rigorous builder's trials testing," said Strategic and Theater Sealift Program Manager Capt. Henry Stevens. "At this stage, JHSV 2 is more complete than the lead ship, and we are benefitting from JHSV 1's lessons learned.
LCS 2 Independence Completes Builder's Trials
LCS2 Independence, the high-speed trimaran combatant ship being constructed by shipbuilder Austal USA in Mobile, Alabama, as part of the General Dynamics Littoral Combat Ship Team, successfully completed a series of tests known as builder's trials on October 18 in the Gulf of Mexico. The trials included more than 50 demonstration events that rigorously test the ship and all of its systems in preparation for final inspection by the Navy before delivery. Notable achievements during the trials included reaching a sustained speed of 44 knots during the required four-hour full-power run…

Now the Carousel Ship
Technical proposals for the shipment of natural gas under compression rather than in the refrigerated, liquefied state have surfaced from time to time over the years, but have received a lukewarm response from the marine industry. The considerable cost of the shipboard containment methodology has been a major stumbling block. Now, a Canadian engineering contractor has come up with an altogether more economic solution to the cargo carrying needs of compressed natural gas (CNG), and pitched at relatively short-distance sea transport applications. Instead of the prohibitively expensive pressure bottles that have earlier been central to CNG transport concepts…
Salacia Returns to Boston
Boston Harbor Cruises recently completed the first successful ferry service between St. Thomas and St. Croix in the U.S. Virgin Islands. Salacia, the largest of the company’s high-speed catamarans, built by Gladding-Hearn Shipbuilding, returned to Boston, having carried from 200 to 700 passengers daily between the islands from November til early May. Until now, islanders normally traveled between the islands by plane. While not the first vessel to attempt this run, Salacia is the first to succeed. “This is probably the most difficult ferry route in the country,” explained Chris Nolan, Boston Harbor Cruises’ managing partner. “The easterly winds blow 15 to 20 knots. The seas were three to five feet eighty percent of the time and would frequently increase to six to eight [feet].
