Installation of a GE Jenbacher J624 reciprocating engine into an existing facility that previously housed a Wärtsilä reciprocating engine. The project team had to utilize the existing facility and BOP utilities to support the installation of the GE engine. This included removing the wall for the installation of the engine, modifying the cooling water, fuel gas, lube oil, and exhaust piping. The wire and cable was removed and replaced to support the new engine. In addition to the new wire, a new switchgear section and loadbank was added to the facility to support supplying the power to the grid.
