The Challenge
Cost and limited space
Aggreko was contacted by General Dynamics Electric Boat to help power the overhaul of a US nuclear submarine, the USS Hartford. After an initial consultation, we knew that their request to use traditional diesel generators would be an inefficient and expensive solution. The high demand on the existing infrastructure in the US shipyard was putting pressure on their facilities. There was simply no room to fit the number of generators needed for the job.
Key Facts
The Solution
Aggreko technical expertise
Rather than choosing a diesel solution that would’ve cost them millions in fuel costs, we proposed and engineered a solution that involved stepping-down their high-voltage on-site power, whilst reducing emissions and noise at the same time. We installed specialty 2,500 V power transformers to help them get the power they needed to a usable voltage and distributed it around the site.
The Impact
Millions of dollars saved at a General Dynamics Electric Boat shipyard
Due to Aggreko Sales and Engineering’s quick and out-of-the-box thinking, we saved our customer millions on rental and fuel costs. We helped our customers see the full picture and keep their environmental footprint down to a minimum.
