This is a reprint of a paper presented at the recent Ships in Lay-Up Conference held in Sandefjord dealing with the search for cheap methods of ship conservation during lay-up periods. Thorough protection of an engine room and its components can be achieved by dehumidification, since corrosion of unprotected steel ceases below 50% RH. The same applies to electric apparatus in general and to decay and rot. AB Gotaverken undertakes complete dehumidification installations as package deals, according to type of ship, climatic conditions, etc. The dehumidification process can be based on cooling and condensation of the water or absorption in regenerative silica gel dryers, in particular what are termed Hunter dryers with rotating drying wheels. These devices bring about a reduction in the absolute humidity in the air compared with heating methods, which merely reduce the RH but keep the dewpoint constant. Other methods, such as smearing with oil, are also briefly reviewed and conservation of various parts of the ship is dealt with separately.
