This chapter covers air conditioning for oceangoing surface vessels, including naval ships, commercial vessels, fishing boats, luxury liners, pleasure craft, and inland and coastal boats, as well as oil rigs. Although the general principles of air conditioning for land installations also apply to marine applications, factors such as weight, size, fire protection, smoke control, and corrosion resistance take on greater importance, and new factors (e.g., tolerance for pitch and roll, shipboard vibration, watertightness) come into play. The importance of shipboard air conditioning depends on a ship’s mission. On passenger vessels that focus completely on passenger comfort, such as cruise ships and casino vessels, air conditioning is vital and a significant energy consumer. Aboard commercial vessels (tankers, bulkers, container ships, etc.), air conditioning provides an environment in which personnel can live and work without heat stress. Shipboard air conditioning also improves reliability of electronic and other critical equipment, as well as weapons systems aboard naval ships. Air conditioning on oil rigs serves the same purpose as with commercial vessels (i.e., providing a suitable environment for workers), and for larger rigs with significant accommodation areas, the amount of cooling can be substantial, similar to passenger vessels. Oil rig applications also introduce the additional consideration of operating within areas classified as hazardous. This chapter discusses merchant ships, which includes passenger and commercial vessels, and naval surface ships. In general, the details of merchant ship air conditioning also apply to warships. However, all ships are governed by their specific ship specifications, and warships are often also governed by military specifications, which ensure air-conditioning system and equipment performance in the extreme environment of warship duty.
