Jet engine designs are frequently modified for non-aircraft applications, as industrial gas turbines or marine powerplants. These are used in electrical power generation, for powering water, natural gas, or oil pumps, and providing propulsion for ships and locomotives. Industrial gas turbines can create up to 50,000 shaft horsepower. Many of these engines are derived from older military turbojets such as the Pratt &amp; Whitney J57 and J75 models. There is also a derivative of the P&amp;W JT8D low-bypass turbofan that creates up to 35,000 Horse power (HP)
