GENERAL DESIGN OF MAIN PROPUSION FOR LNG CARRIERS

ABSTRACT

Natural gas is a clean, high calorie and low pollution gas fuel. With our rapid economic growth, energy demand is also growing rapidly. Natural gas is an ideal fuel. It is the first time that our country set up a big receiving terminal in GUANGDONG province to meet the economic growth demand of the southeast coastal. When natural gas is cooled down to its boiling point of–1620C and liquefied to LNG, its volume is co

ndensed to only one six hundredth (1/600) of gas volume. This is an advantage as a ship cargo. The liquid gas is imported from Australia and cross-ocean shipping needs the special LNG carriers to carry out. This time, HuDong-ZhongHua shipbuilding group has won the tender to build LNG carriers; it is great honors because it is the first time to build a LNG carrier in our shipbuilding history. Such high-tech ships’ building means great challenge and risk, how to delivery the carrier on schedule and guarantee the quality is a complete new and hard task. One of main features of LNG carriers is steam turbine propulsion. This article analyzes and studies recent steam turbine propulsion and is hoped to be a

reference for the developing, designing and building LNG carriers’ main propulsion. Chapter 1 introduces background of the article; expound the purpose and mainly task. Chapter 2 introduces the physics characters of natural gas and ways of liquid gas transportation. Also briefly explain the GUANGDONG project. Chapter 3 reviews the history of LNG carriers and types of cargo tanks, and then introduces present status of steam turbine propulsion. Chapter 4 first analyzes several main propulsion plants of LNG carrier and then draws a comparison from the economical evaluating viewpoint. Chapter 5 focuses on researching the components and principle of steam turbine propulsion, for instance, steam boiler and steam turbine, etc. meanwhile, analyzes the heat cycle, illustrates typical examples and heat lines. Chapter 6 on the basis of previous chapter and the situation of GUANGDONG project, explains the main features of LNG carriers’ steam turbine propulsion and analyzes the related systems. Also shows the detailed heat line and draws the preliminary engine room arrangement for reference. KEY WORDS: natural gas, liquid natural gas, LNG carrier, steam turbine propulsion, steam turbine, dual fuel boiler
