A new boil-off gas re-liquefaction system for LNG carriers based on dual mixed refrigerant cycle

Cryogenics (Guildford), 2018
A new boil-off gas (BOG) re-liquefaction system for LNG carriers has been proposed to improve the system energy efficiency. Two cascade mixed refrigerant cycles (or dual mixed refrigerant cycle, DMR) are used to provide the cooling capacity for the re ...

Modification of LNG Carriers for Regasification

Offshore Technology Conference, 2003
Introduction This paper addresses the issues surrounding the modification of existing Liquefied Natural Gas (LNG) carriers to act as floating storage and provide regasification facilities. In the context of studies undertaken, 'existing' may refer to an LNG vessel of any age ranging from one in excess of 20 years ...

Financing LNG carriers

Marine Policy, 1979
Abstract The author examines the various methods of finance for LNG carriers at each stage of funding. First, he describes the various factors involved in the funding of LNG carriers, and continues by highlighting the different methods of finance. He concludes by summarizing the prospects for shipping finance in a severely depressed ship sale and ...

A Novel LNG Tank Containment Design for Large LNG Carriers

Day 2 Thu, October 20, 2005, 2005
new concept for Large LNG carriers is proposed. This design utilizes membrane tanks with a cross section that reduces the liquid free surface inside the tanks. This reduced free surface results in lower sloshing impact loads on the tank membrane and insulation, extending membrane technology to larger LNG carriers than have hitherto been possible ...

The effects of LNG-tank sloshing on the global motions of LNG carriers

Ocean Engineering, 2007
Abstract The coupling and interactions between ship motion and inner-tank sloshing are investigated by a time-domain simulation scheme. For the time-domain simulation, the hydrodynamic coefficients and wave forces are obtained by a potential-thoery-based three-dimensional (3D) diffraction/radiation panel program in frequency domain.

Reliability assessment of reliquefaction systems on LNG carriers

Reliability Engineering & System Safety, 2008
The paper gives an introduction to reliability assessment of reliquefaction systems for boil-off gas (BOG) on LNG carriers with focus on redundancy optimization and maintenance strategies. The reliability modeling is based on a time-dependent Markov approach. Four different system options are studied, with varying degree of redundancy.

Propulsion Solution for Icebreaking LNG Carriers

Offshore Technology Conference, 2021
Abstract Since 2007 the traffic volumes in the arctic seas have substantially increased, especially in the North-East Passage following the development of major oil and gas projects. In development of icebreaking LNG tankers the selection of propulsion system is playing a major role determining the vessel performance, safety and ...
