Indoor Climate in Ships

Abstract

In the modern world the share of passenger traffic on the ship is not great. Basically passenger ships are used for the entertainment cruises. As regards cargo ships people are responsible for delivering cargo so comfortable indoor conditions should be created for people as well as for cargo.

Life on shipboard has own specific features and specific problems which are not close to problems of life on shore. It’s necessary to realize that seafarer spends a lot of time in confined space so requirements for ships are stricter than for buildings. Thesis contains information about indoor air conditions established in Russian and European norms. In addition general information about lighting, use of synthetic materials and specifics of water supply during the voyage is provided. Besides that thesis contains information of specific features of seafarers’ life such as an effect of ship vibration and ship motion.

Another important feature of seafarers’ life is noise mainly caused by shipboard power plant and different mechanisms. These mechanisms (fans) are included to shipboard ventilation and air conditioning system so noise can spread widely through duct line system. There are several ways to prevent future noise problems and solve existing problems. Main preventive way is to conduct acoustic calculation with calculation of expected noise levels. Thesis contains example of acoustic calculations and comparison of results with Russian and European standards. Solution of existing noise problems are mostly construction solution methods - coatings, insulations, dampers etc.
