The document discusses refitting exhaust systems on ships to meet requirements for noise reduction, back pressure control, space limitations, and regulations while managing costs and timelines. It describes balancing these factors and providing solutions within budget and on schedule. An example refitting project is described that used modular silencers to replace an old system, saving 69% time and 85% costs by avoiding dismantling other equipment and keeping the ship in the water.
