TECHNEWS ROBOT named Emily could save your life
CAT POWER for ALP’s four ocean-going AHTS CATERPILLAR MARINE will supply Cat power and propulsion solutions to four Ulstein SX157 design oceangoing Anchor Handling Tug Supply (AHTS) vessels currently under construction at Japan’s Niigata Shipbuilding & Repair for ALP Maritime Services, the Netherlands based company acquired by Teekay Offshore back in February. The vessels are specifically designed and developed for towing large structures such as oil rigs and floating production units over long distances. The bollard pull for each of the four vessels will be 300 tons, with the vessels capable of operating at full loads for 45 days without refueling.
Each vessel will have four MaK 9 M 32 C propulsion engines, rated at 4,500 bkW at 600 rev/min and three Cat C32 auxiliary generator sets rated at 940 ekW at 1,800 rev/ min, as well as one Cat C9 generator set to provide emergency power. All four vessels will each be equipped with two AEM shaft generators rated at 3,150 ekW at 1,200 rev/min. Each AHTS has two Cat BCP1330F main propellers, two BTT625 tunnel thrusters and two BTT419 tunnel thrusters. The MaK and Cat power and propulsion solutions will be delivered for the four ships over the course of the next year. marine.cat.com
FOR SEVERAL YEARS, Emily has been among the most popular baby names in the U.S. It also happens to be the name of a 25-pound high-tech, remote-controlled robot that could save a life at sea. Ideal for commercial shipping, cruise ships, oil rigs, private boats, pier/docks, and environments where flash floods are possible, the Emergency integrated Lifesaving LanYard (EMILY) is designed to provide flotation and assistance to multiple swimmers at a time. Designed by Hydronalix, EMILY, which measures 50 inches x 15 inches x 2 inches, weighs 25 pounds, acts like a jet ski reaching a top speed of 22 mph. The rescue device features a durable Kevlar reinforced hull and marine grade canvas to ensure product longevity. According to the company, the robot is “engineered to race through heavy surf;” can be deployed from a moving watercraft; features a “safe, internal propulsion [that] will not harm victim(s) or catch on rocks and sand; and can pull a recovery rescue line, up to 800 yards long, through strong currents and large surf.
PAIR OF WÄRTSILÄ LOW-SPEED GENERATION X ENGINES MAKE THE GRADE
A PAIR OF WÄRTSILÄ ENGINES have passed tests verifying each engine’s performance criteria. The Wärtsilä X72 and the Wärtsilä X62—both part of Wärtsilä’s Generation X low speed engine series—cover the mid-bore end of the market. The two-stroke engines feature Wärtsila’s electronically controlled, common rail system with controlled fuel injection—which 28 MARINE LOG July 2014
provide operators with excellent fuel efficiency and lower operational costs. The Wärtsilä X72 successfully passed the Type Approval Test (TAT). The passing of TAT shows that the engine fulfilled all classification society requirements and met all SOLAS standards, facilitating the engine’s introduction into the market. “The key value adding feature of this engine is that its high level of efficiency lowers the operational costs for owners, operators and charterers,” says Martin Wernli, Managing Director, Wärtsilä Switzerland and Vice President, 2-Stroke, Wärtsilä Ship Power. Meanwhile, the Wärtsilä X62 passed its Factory Acceptance Test (FAT). Passing the test indicates that the engine fulfilled all design requirements for performance and functioning, and has been accepted by
both the customer—in this case Greek ship owner, Kyklades Maritime Corporation–and classification society DNV GL. The X62 engines will power four 115k Aframax Product Carriers being built at the HHI Gunsan Shipyard for Kyklades. The ships will fully comply with IMO’s Energy Efficiency Design Index (EEDI). Compared to earlier generations, the Wärtsilä X62 achieves an additional 10 percent in daily fuel consumption and promotes the optimization of lubricating oil consumption. Wärtsilä’s Generation X engine line is designed for Afromax tankers, Panamax/ Kamsarmax bulk carriers, as well as Feeder container vessels. Both the Wärtsilä X72 and X62 are IMO Tier 2 compliant and will be available with Tier 3 options. www.wartsila.com
