The Gamma Propulsion System (TGPS), a completely new, innovative way to convert power (Watts of energy in) to thrust (Watts of energy out).


There are around 50,000 merchant ships trading internationally.

Fuel costs now account for up to 50% of operating costs… Shipowners therefore have a strong incentive to reduce their fuel consumption.

In 2006 there were more than 1,000 water parks in North America. Approximately 78 million people visited them over the summer.


A group of engineers have developed a completely new method of propelling a displacement vessel while using significantly less energy than that consumed by a traditional un-shrouded propeller, yet still maintaining the same performance.

Comprising a series of diesel electric units, strategically located completely INBOARD down both sides of the vessel, the Gamma Propulsion System (TGPS), is easy to build and very easy to retro fit to existing ships.

The Gamma Propulsion System (TGPS) will change the face of water propulsion forever by delivering:

  • A system, certified as being significantly more efficient.
  • A system capable of saving over 35% of propulsion fuel usage
  • A system that would emit over 35% less pollutants
  • A system capable of manoeuvring a displacement vessel in all directions – forward, aft, sideways, spin in its own length and crab – using its power range right up to full thrust.
  • A system purpose-designed as the main method of propulsion for freighters, bulk carriers, oil tankers and container ships.

Data collected from controlled testing, and certified by Lloyd’s Register clearly demonstrates that TGPS delivers significant thrust with previously unthinkable efficiency.

This same technology can also be utilised in large transfer pumps for the marine and irrigation industries, emergency flood pumping and the mining industry. Typically, volumes like 3, 5, 10 or even 20 cumecs can be pumped with these same efficiencies with scaled-up versions of the TGPS pump as tested by Lloyd’s Register.

The TGPS engineers also worked with the technical staff at the Wet-n-Wild water theme park on Australia’s Gold Coast. Their brief was to develop a more efficient circulating pump for the theme park’s Calypso Beach.

The TGPS pump delivered a 12% increase in performance but only used 2.04 kW, compared to the original 22 kW.  Note: Some of the efficiency gained is due to the improved delivery systems recommended by Gamma Light & Heavy Industries Ltd.
