GE Electric Propulsion Equipment for LNG Carriers
GE’s Power Conversion business has received a new order from Kawasaki Heavy Industries, Ltd. for electric power and propulsion systems for two LNG carriers. The LNG carriers will be built for the purpose of transporting LNG from Louisiana, U.S.A. Their construction is scheduled to be completed from 2017 through 2018. According to GE, from the perspective of improved performance, electric propulsion technology is optimal for LNG carriers. GE said its induction-based propulsion motor technology and high output power pulse width modulation (PWM) technology improve reliability and help lower maintenance costs for vessels. “GE has demonstrated a low risk solution to KHI…
Rolls-Royce, GPA Collaboration Pays Dividends
Rolls-Royce and Guido Perla and Associates, Inc. (GPA) collaborative efforts are delivering results for customers in North America. Rolls-Royce and GPA most recently teamed up last year to provide a highly innovative design and power & propulsion systems integration solution for two PSVs for Jackson Offshore Operators. Delivery of the first two GPA 675J PSVs, currently under construction at BAE Systems’ shipyard in Jacksonville, Florida, will be made in 2014. The option for two additional vessels of the same type was exercised earlier this year.
Rolls-Royce to Upgrade Dorothy Ann
Rolls-Royce Commercial Marine has been contracted to upgrade Interlake Steamship Company’s Tug Dorothy Ann. The 124-foot, 7,200-horsepower Z-drive tug is the largest Z-drive ATB tug built to date in North America and is mated to the barge Pathfinder. The duo is engaged in hauling bulk commodities on the Great Lakes. The upgrade will convert the Dorothy Ann’s Rolls-Royce/Ulstien azimuth thrusters from fixed-pitch to controllable-pitch propellers. The project will include replacement of the lower drive units as well as all thruster control systems on the vessel.
