Shipbuilding Under the first agreement, Eastern Shipbuilding Group will build two STX Marine-designed 340 ft x 73 ft x 29.5 ft heavy lift construction vessels for HGIM. To be named the Harvey Sub-Sea and the Harvey Blue-Sea, the vessels will each have a 250-metric ton active heave compensated crane,12,000 ft2 of usable deck space, accommodations for 120 and a heli-deck. The two vessels are in addition to a STXCV 310 Light Construction Vessel, the Harvey Deep-Sea, set for delivery from Eastern Shipbuilding next month. Under the second agreement, HGIM exercised an option with TY Offshore for the construction of the sixth dual fuel offshore vessel. This addition will enable Harvey Gulf to become the largest owner/operator of clean burning LNG OSVs in the world. The last deal is for the purchase of 11 DPS-2 offshore supply and fast supply vessels from Gulf Offshore Logistics. With the latest addition, HGIM will own 46 deepwater, DPS-2 vessels with an average age of less than five years old.

HORNBECK, TIDEWATER INKED DEALS WITH LEEVAC Hornbeck Offshore Services (HOS), Covington, LA, signed a contract with Leevac Shipyards Jennings LLC, Jennings, LA, for the construction of two 302 ft x 76 ft x 26 ft, 12,070 bhp diesel electric-powered MPSVs based on an STX Marine SV 310 design. Leevac President and CEO Christian Vaccari, says, the contract will extend the shipyard’s backlog into early 2016. Leevac is currently building two Z-Tech 2400 Class Escort Tugs for G & H Towing Company, one MMC 879 PSV, two Leevac Design Services (LDS) 300 DE PSV’s for Tidewater Marine, and two LDS 270 DE PSV’s for Aries Marine. The two 300 ft x 62 ft x 24 ft diesel electric platform supply vessels for Tidewater includes options for two additional vessels. Vaccari said, “Activity in Gulf Coast shipyards has significantly increased and the availability for shipyard slots is starting to disappear.” Last year, HOS signed a deal with Bollinger Shipyards, Lockport, LA, to stretch six 200 Class DP1 OSVs to 240 Class DP2 vessels. Other operators such as Gulfmark Offshore, have used a similar tack to enhance their fleets. Conrad Shipyards, Morgan City, LA, completed the third of three lengthenings for Gulfmark earlier this year, delivering a 230 Class vessel. Its the sixth such project Conrad has completed for Gulfmark. The publicly traded operator is now set to lengthen 10 more vessels to 260 Class.

FERRY INVESTMENT Ferries have and will continue to be a vital part of the U.S. public transportation, particularly in major metropolitan regions such as New York and Seattle, which combined serve upwards of 55 million commuters and tourists on an annual basis. New York has one of the largest publicprivate ferry networks in the U.S., with some 20 routes that carry 30 million passengers annually. The largest ferry by annual ridership is the Staten Island Ferry operated by the New York City Department of Transportation (NYCDOT). Like other vessel operators, the NYCDOT is under tremendous pressure to reduce operating costs, while meeting stricter environmental regulations on emissions. The solution to that conundrum is at the heart of a pilot project to convert an Alice Austen Class ferry to burn Liquefied Natural Gas (LNG). Converting the ferry to burn LNG as opposed to ultra-low sulfur diesel fuel could reduce fuel costs by as much as 40 percent, says Captain James C. DeSimone, COO, Staten Island Ferry. “CO2 is expected to be reduced by 20 to 30% and SOx and NOx close to zeroed out,” he says. The pilot project would validate these assumptions, as well as others such as expected fuel consumption, horsepower,

emissions and overall cost. Officials from the FDNY accompanied DeSimone on a recent visit to Norway to assess gas-fuelled ferries and research operational issues such as bunkering. The trip was also intended to expose the FDNY to gas-fuelled vessels and allowed them to meet with the City of Bergen Fire Department to discuss their concerns about LNG. There is currently a moratorium on the transport and storage of LNG in New York City. The moratorium dates back to a 1973 accident when 37 workers were killed while repairing an empty LNG tank at a Staten Island site. DeSimone says the FDNY is working with the NYDOT on fueling options for the LNG ferry. LNG fueling could possibly be performed via tanker truck on Staten Island. Another option available, says DeSimone, would be to fuel the ferry in New Jersey. The pilot project is funded by a $2.3 million grant and additional money from New York City and would be accomplished as part of a normal dry docking. The success of the conversion of the 1 , 2 0 0 - p a s s e n g e r A l i c e Au s t e n C l a s s ferry—either the John Noble or the Alice Austen—to gas-only operation could have broader implications for the Staten Island Ferry fleet. The city wants to replace its
