GLHI develops new energy efficient propulsion system

30 April 2012

Australia based Gamma Light and Heavy Industries (GLHI) has developed a new method of propelling a ship which is claimed to save at least 75% of energy consumption without reducing performance.

The Gamma Propulsion System (TGPS) can be outfitted in exiting vessels, and according to the company, can replace a 4,000 HP engine with a maximum 1,000 HP TGPS while maintaining the same thrust.

The TGPS will feature a series of diesel electric units, which can be fitted completely inboard down both sides of the vessel, in the cargo hold on retro fits occupying a space of 8m3.

Gamma Light & Heavy Industries CEO Doug Bruce said when TGPS is strategically positioned inboard along each side of the hull a ship can manoeuvre itself in all directions -- forward, aft, sideways, spin in its own length and crab -- using its power range up to full thrust.

"TGPS positioning delivers built-in redundancy for the unlikely event of an electric motor failure, where a motor can be easily and inexpensively replaced, even en-route. Servicing is also inexpensive and simple to perform, as everything is located inboard," Bruce said.

The propulsion system can power freighters, bulk carriers, oil tankers and container ships while the system is capable of propelling a vessel in all directions - forward, aft, sideways, spin in its own length and crab.

AS the TGPS will consume less fuel leading to 75% less pollutant emissions, GLHI claimed.

The test of the system was carried out in Queensland, Australia, on behalf of Douglas Bruce/Pacific Paramount to verify the performance of the electrically-driven pump units for ship propulsion.
