CONCEPTS OF REFRIGERATION CYCLES AND CRYOGENICS FOR LNG TANKERS

This paper represents an overview about cryogenics applications in the maritime field and onboard commercial vessels. Basics thermodynamics in general and cryogenic refrigeration in particular are theoretical knowledges which become compulsory when we are dealing with complex processes like liquefaction, re-liquefaction and boil-off. The papers aim is to familiarize the students/crew members onboard LNG tankers with the basic concepts of refrigeration cycles and cryogenics.
