Cummins KTA50

We worked on this project with some of our OEM partners to heavily modify a standard Cummins KTA50-G3 generator to meet Explosion Proof standards required for an operator on an Oil rig, while also being Diesel Dual Fuel capable.

By adding the optional Bifuel capability to the prime movers on an oil rig the operator can use associated gas to power the rig with upto 70% replacement of diesel and achieve not only cost optimization but also extreme environmentally friendly operation.

The conversion was carried out with full reporting capability and fuel monitoring of both diesel and gas.

In our nearly two decades of Dual Fuel conversion experience we have converted nearly every model of engine by most major manufacturers. 

BENEFITS OF DUAL FUEL ENGINES

In the oil and gas market, fuel is one of the largest contributors to total cost of operation. Dual Fuel engines allow for impressive reductions in these costs. The rapid expansion and abundance of natural gas in some areas of the world provides a dramatic cost advantage.

The integrated controls optimize substitution rate based on operating conditions, to seamlessly and automatically transition between diesel fuel and dual fuel modes. The ability to operate on 100 percent diesel fuel or dual fuel modes provides flexibility based on local availability of natural gas.

 

SUBSTITUTION RATE

A critical parameter for dual fuel operation is the substitution rate – the portion of total fuel energy provided by natural gas. A maximum substitution rate of 70 percent can be achieved with Dual Fuel for applications with high stable load factors.

Natural gas can be substituted for diesel fuel in varying proportions according to operating conditions. Dual fuel substitution rate is optimized with a system of sensors and control logic integral to the equipment package. Though many factors affect actual diesel substitution rates that can be attained, rates of 50 to 70 percent gas on an energy basis have been reported.
