Analysing the risk of LNG carrier operations

Reliability Engineering and System Safety, 2008
This paper presents a generic, high-level risk assessment of the global operation of ocean-going liquefied natural gas (LNG) carriers. The analysis collects and combines information from several sources such as an initial hazid, a thorough review of historic LNG accidents, review of previous studies, published damage statistics and expert judgement ...

Stern Slamming of an LNG Carrier

Volume 5: Materials Technology; CFD and VIV, 2008
Rational assessment of stern slamming of a large twin screw LNG carrier comprised prediction of hydrodynamic impact loads and their effects on the dynamic global structural behavior of the hull girder. Linear theory obtained regular equivalent waves that caused maximum relative normal velocities at critical locations underneath the ship’s stern ...

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 ...

Predicting Loads on a LNG Carrier With CFD

29th International Conference on Ocean, Offshore and Arctic Engineering: Volume 6, 2010
The Current Affairs Joint Industry Project was initiated to develop the understanding and tools for the assessment of current loads on offshore structures. CFD is one of these tools requiring a good understanding of the underlying physical and mathematical models.
