Walker's New Airsep Filter Clears the Air Walker Engineering's New CCE AIRSEP system is a closed crankcase systems available for marine diesel engines. Recently adopted as standard equipment for the new Cummins QSB and QSC marine engine series, the system is designed to offer a high-efficiency, replaceable coalescing filter, an integrated turbo silencer and a washable air filter. For years, AIRSEPs have kept engine rooms clean from blowby and significantly increased the time between engine maintenance intervals. The system can also be found on select Caterpillar marine diesels, and is available in an upgrade kit for existing engines equipped with the traditional AIRSEP system installed on any diesel engine.

Captain David Strickland was first introduced to Sword Marine in 2004 and was impressed with the JetPac's performance. He was looking for an outboard engine with great fuel economy, longevity and good handling. Since the JetPac is powered by a diesel engine, Strickland can also take advantage of available biofuels. "The JetPac has excellent fuel efficiency using regular diesel," he said. "By using a biofuel derived from vegetable oil, I still get great fuel economy, but with fewer emissions, and that's even better for the environment." The Sword JetPac combines a marinized automotive engine coupled to a waterjet via a toothed Kevlar drive belt, completely enclosed in a waterproof, fiberglass shell mounted to the exterior of the boat's transom. Built-in flotation reduces the boat's draft and eliminates drag. For more information, visit www.swordmarine.com J. Ray McDermott's Mid-East Lay Barge Since 1960, J. Ray McDermott's Middle Eastern facility has fabricated and installed more than 630 structures, 330,693ST of steel, and has installed over 2,610 miles of pipeline throughout the Arabian Gulf, Egypt, India, the Caspian, Africa and the North Sea. Recently the company upgraded one of its assets. The firm's Derrick Lay Barge-27, owned by Hydro Marine Services but operated by McDermott, now has an impressive set of specifications. At 420 x 128 x 28 ft. this is a big platform. The barge's main crane gives it some big capabilities. The Clyde Model 76DE-revolving crane is capable of lifting 1400 tons with its 235-ft. main boom at 115 ft. The auxiliary boom extends to 270 ft. and can lift 750 tons at 160 ft. while the whip extends to 300 ft. and will lift 250 tons. With the crane fixed over the stern it will lift 2400 short tons. The auxiliary electric power for the barge, which was originally built at the Kanrei yard in Tokushima Japan, is provided by four 1150 kW generators powered by 38-liter V-12 Cummins KTA38-D diesel engines. The generators sets produce 460 volt 60 Hz three phase power with the diesel engines turning at 1800 rpm. With the addition of these four gensets, the barge now has a total of 32 Cummins engines in various applications such as mooring winches, and auxiliary generator sets together with the heavy-lift crane. The barge refit work was carried out in Dubai Dry Docks. The refit was mainly for changing some hull plates and installation of the four Cummins gensets with Danway supplied synchronization and distribution panels. The final commissioning was done at the Dubai McDermott works. This repower was part of a rolling refit to extend the barge life by another 15 years. To build such a barge would take 18 months and cost in the range of $240 m. McDermott has six of these lift barges of various weights worldwide. And the game changes again.
