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.

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.

Membrane Tank Lng Carriers

Revue de l'Institut Français du Pétrole, 1996
This document describes the two membranes containment systems developed by the company Gaztransport & Technigaz for the transportation at sea of liquefied natural gas (LNG) and applied by several shipyards in Europe, United States, Japan and Korea.

Model Tests: LNG-Carriers in Ice

Volume 2: Ocean Engineering and Polar and Arctic Sciences and Technology, 2006
Approximately on third of the world’s known and not yet exploited reserves of natural gas are in Russia. The overwhelming majority of these reserves are in Artic and Subarctic areas. But not only in Russia, also in other areas like Canada and USA, natural gas reserves are found in harsh and ice covered environments.

Design for safe and efficient LNG Carriers

SNAME Maritime Convention, 2005
The market demands for larger freight volumes are pushing the LNG industry towards larger vessels, new concepts and new technical solutions. Alternative machinery installations are being investigated including one steam turbine, one/two slow speed diesel(s), one/two dual fuel engine(s), one/two gas turbine(s) and one/two diesel electric installation(s).

An introduction to the marine transportation of bulk LNG and the design of LNG carriers

Cryogenics, 1974
Abstract The special problems connected with building ships to carry liquefied natural gas are summarized and the different designs of ships at present in use are discussed. Other problems concerned with the marine transport of LNG such as handling, pumping systems, and dealing with boil-off are also considered.

Comparison between conventional LNG carriers and SRV- LNG carriers

2015
Up to the middle of the last decade LNG tankers were built only when the gas exploitation project as well as the market to sell it existed. Ships were operating on the basis of the long term Sales and Purchase Agreement, and predetermined terminals for LNG loading and unloading.

LNG Marine Carrier Construction

Marine Technology and SNAME News, 1972
The author describes the several concepts around which the existing marine LNG containment designs are formulated. The Kvaerner-Moss spherical containment system without secondary barrier is discussed in some detail. The design analysis of that system is presented in a step-by-step fashion as actually performed, along with descriptions of tank ...

Modeling underwater penetration of LNG carrier

Process Safety Progress, 2008
AbstractAn underwater breach of a tank in a double‐hulled LNG carrier poses several challenging questions to be addressed by an adequate model. This article describes a model that accounts for the following phenomena: (1) LNG tank vapor space pressure decreasing by the piston effect of outflow (the effect a decreasing water level pulling down the ...
