With fuel savings between $1.50 and $2.00 per diesel gallon equivalent (dge), LNG-fueled trucks are being used by fleets for their most demanding routes: heavy haul, double-shift operations where truckers can consume 200 gallons per day, the World LNG Fuels conference concluded in January.
By using domestic LNG, operators can save as much as $75,000 annually in fuel costs, enough to pay for the cost of LNG equipment in 18 months.
Hindering this, however, is the higher weight of the LNG-fueled trucks, which weigh between 1,800 and 2,000 pounds (820 and 910 kg) more than their diesel counterparts. By law, most tractor-trailer combinations are limited to 80,000 pounds. Once the weight of the truck and trailer are deducted, payload capacity can be as little as 35,000 pounds. Thus, an increase in truck weight of 1,800 to 2,000 pounds can wipe away profits.
Truckers like Hoopes Transport President Preston Hoopes would like the U.S. DOT to consider waivers for the extra weight, given the benefits of the cleaner, domestic fuel.
“We need the government to allow extra weight. If the government wants us to use domestic LNG and CNG, they’ve got to give us weight help on our trucks,” Hoopes told World LNG Fuels 2013, held in Houston.
“We’re trying to get another trucking company in Pennsylvania to use LNG. They said ‘we can’t afford the extra weight, 2,000 extra pounds, which over a year’s time costs $20,000 in lost revenue,’” he said.
Hoopes operates some 50 trucks, 16 of which are LNG fueled, for a variety of cargos. In recent months, management has assigned their LNG units to their most fuel-intensive routes. They would like to move into the LNG-fuel supply business if the issue of weight can be resolved.
The AMC Connector, the largest and most advanced cable- and pipe-laying vessel for deep ocean operations has arrived to Stavanger, Norway, to undergo modifications. The vessel will be docked at GMC Yard in Buøy outside Stavanger until March 11th 2012.
The 156-meter long multi-purpose vessel, AMC Connector, is an advanced ship with a high cargo capacity, a variety of special equipment and more than 190 kilometres of cable length. GMC Yard will modify the ballast tanks and building sponsoons under the hull. Work to be carried out includes adding a new auxiliary keel, installing a new stabilising tank and a new VLS tower on the vessel.
“The job is shared between GMC Yard, STX in Florø and the ship owner, Aker Marine Contractors. All already have workers on site for the stay in Buøy, says Operations Manager Kjell Olsen of GMC Yard. A total of 200 people are engaged in modifying the AMC Connector in this period.”
GMC Yard has docking capacity for vessels up to 280 meters, and the AMC Connector has no problem fitting into the large Dock 2 at Buøy. The vessel will be used for laying the power cable from land to the Goliath-field in the Barents Sea.

The Skandi Achiever makes a stop at the Port of Pensacola on Wednesday for a crew change.
by Katie McFarland
The Port of Pensacola continues to be busy with the arrival of a specialized diving vessel Wednesday morning.
The Skandi Achiever, a dive-support boat, is stopping in Pensacola for an equipment and crew change, said Buddy McCormick, director of business development and public relations for Offshore Inland.
The saturation dive system allows 18 divers to trade off staying in four, three-man decompression chambers. The divers can descend and perform work on equipment like offshore rigs then recover from deep-water diving, McCormick said.
The 350-foot vessel arrived at the port at about 6:30 a.m. Wednesday after a trip from Europe, he said.
The vessel, owned by French oil and gas infrastructure giant Technip, will be at the port for four to five days before going on its next three- to four-week job in the Gulf of Mexico. It will return to Pensacola to pick up equipment after the job.
Technip recently purchased Global Industries and now owns the Global 1200 pipe-laying vessel that recently was berthed at the port and is scheduled to return Oct. 27.
Technip will have almost 30 vessels working in the Gulf of Mexico, McCormick said.
Offshore Inland leases a warehouse at the port and has the right of first refusal for vessels docking at berths one and two.
McCormick said he’s pleased with the recent influx of vessels at the port and hopes to create jobs by bringing even more into the port.
The massive catamaran-style lift with double golden arches that arrived at the port Oct. 7 is scheduled to depart today, port officials said.
The Versabar 10,000 stopped in Pensacola for routine maintenance because of high winds and seas in the Gulf. It was scheduled to depart Oct. 11, but made one trip into the Gulf and returned for a second stop Saturday.

Arctech Helsinki Shipyard has started construction of two new icebreakers for Russia’s largest shipping company Sovcomflot. The two Multifunctional Icebreaking Supply Vessels (MIBSV) are planned to be ready by spring 2013 and will be used as supply vessels for Exxon Neftegas’ platform at the Sakhalin-1 field, Regnum reports.
Both vessels will be similar measuring 99.2 m in length and 21.7 m in breadth. Their four engines have the total power of 18,000 kW. The vessels are designed for extreme environmental conditions and will be operating in thick drifting ice in temperatures as cold as – 35°C. They have an icebreaking capability of 1.7 m thick ice and are also equipped for oil combating, fire fighting, and rescue operations.

Ulstein Sea of Solutions is nominated for the Dutch HME Maritime Innovation Award 2011 for their SOC 5000 vessel design.
The SOC 5000 is a self propelled heavy lift crane vessel design, measuring 180,9 m by 46.4 m with a lifting capacity of 5.000 metric tons. Based on this design two customized versions have been developed which are currently under construction for Subsea Seven and Heerema.
The prize is presented annually to the most innovative maritime supplier of the Netherlands and will be presented at the Maritime Awards Gala that takes place on Thursday 3 November.
