Steel Predecessor News

Robert Allan Ltd. has developed a new all electric pilot boat for service involving short trips where the run to the ship is 5 nautical miles or less.An aluminum version of its steel predecessor, the RAlly 1600-E boasts a fully electric twin screw drivetrain and a substantial bank of high energy density batteries that are recharged from shore power. Twin small auxiliary generators give “get home” and range extension capability but are normally not running. The vessel runs quietly and emissions free and is capable of reaching speeds up to 20 knots.According to the designer…

GE’s Marine Solutions announced it has completed the acoustic attenuation and weight comparison testing between its new lightweight composite LM2500 gas turbine module and the steel enclosure. The results verified a 2,500-kilogram weight reduction and a significant improvement in noise attenuation—60 percent quieter—when compared to its steel predecessor. “The tests compared the noise and weight of the steel enclosure to the novel one piece composite design. Results verified that the new carbon fiber provides a significant reduction in the wall weight and noise, which is vital on weight- and size-constrained surface combatants,” said GE’s Brien Bolsinger, Vice President, General Manager, Evendale, Ohio.
