The challenge
Inefficiency and lower oil prices lead to overcapacity of an existing gas turbine
With two oversized Gas Turbine main engines of 4.3 MW in total power each and the evident consequences of lower oil prices, our customer’s offshore platform power was highly inefficient.
One of the existing gas turbines had a considerably low efficiency of just 14%. With low oil prices also impacting activity levels, the platform was unable to use all of the 4.3 MW that was generated. The overcapacity was increasingly costly and with our customer facing considerable cost pressures, they needed a temporary solution fast.

The solution
Providing back-up power for remaining gas turbine with our gas generators using available APG
By turning off the inefficient turbine our customer needed a backup solution for their remaining online turbine.
They also had to consider if oil prices would go up as fast as they dropped, that they could respond quickly with available power to easily ramp up production. We installed two 2 MW gas generators in parallel with the customers remaining efficient main engine and right sized the power requirement, so the customer was guaranteed power with a higher efficiency.
Our solution can also meet any future production increase power demands as well as providing backup for their existing engine. As the platform used Associated Petroleum Gas (APG) for their gas turbines, we were also able to use the APG taking over the existing fuel for our gas generators, with some modifications for the offshore environment.
We modified the gas train to meet offshore safety specifications, pressure and extended our exhausts.
