Electric ships spur natural-gas-tanker boom

By GE Reports

Electric cars are still rare, but giant electric ships are a different matter. "We started the marine electric propulsion story," says Jean-Philippe Chaignot, a leader in GE's power conversion unit. Electric motors built by GE engineers power some of the biggest and most sophisticated vessels, from aircraft carriers and destroyers to tankers, cruise ships, and Queen Mary 2, the largest ocean liner ever built and the fastest one in service.

Electric ship propulsion is also helping to stoke a global boom in liquefied natural gas (LNG). Ten years ago, the power conversion unit built a propulsion system for the first electric LNG tanker. Today, the GE technology is powering 30 such ships. These seafaring behemoths will soon have more company. Korean ship builders Daewoo and Hyundai just ordered motors and other technology for 23 new LNG ships. "All those ships will have a fully electric propulsion," Chaignot says.

Modern ships have employed different modes of propulsion, from steam turbines and diesel engines to nuclear reactors. The first electric ships sailed a century ago. In 1914, the collier USS Jupiter became the U.S. Navy's first electrically propelled ship. But the early systems were bulky, and ship builders largely stuck with steam and diesel.

But Converteam, a century-old French specialist in building heavy-duty systems that convert mechanical motion into electrical energy, kept improving on electric ship propulsion. Now part of GE, the company slimmed down and perfected the technology, and in the 1980s started making electric motors for cruise vessels.

The concept took off. Today, there are more than 70 electric cruise ships with GE propulsion, and dozens of other merchant, military, and offshore vessels. Cruise lines and navies like electric propulsion because it cuts weight, noise, and vibrations, improves ship efficiency, and saves precious space. "Having an electric propulsion system allows you to mechanically disconnect the power generator from propulsion," says Chaignot. "You don't have to have the main engine right next to the propeller." As a result, the ship's engines and the motor with the propeller can be located in different parts of the ship and connected with electrical cables. This can save shippers as much as 5% in cargo space.

Electric ships make their own electricity; imagine a floating power plant below deck. Each of the new LNG ships has four engines that burn both natural gas and diesel. The engines spin generators that produce electricity. The electricity powers GE electric motors that drive the gearbox, the shaft, the propeller, and other equipment. The GE propulsion systems inside the new tankers will generate a combined 700 megawatts of electricity, enough to power more than 600,000 households.

Power conversion has many other applications. Outside shipping, GE power conversion technology is helping utilities smooth out variable power produced by wind farms and feed it to the grid. Steel makers use the technology to control high-precision rolling mills.
