Standards and Guidelines for LNG ship projects

 The LNG marine transportation industry has an enviable safety record and, in the 49 years since the first commercial cargo was transported from Algeria to the UK, 7,200 million m3 of LNG has been safely delivered on approaching 75,000 loaded voyages. This excellent safety record stems from adherence to rigorous codes and standards for the design, construction and operation of both the vessels employed and the marine terminals where they load and discharge their cargo.The codes, standards and industry guidelines were written by drawing on the expertise of the people engaged in the industry and they have been continuously updated and reviewed in light of experience. With the advent of ‘small scale’ LNG usage, particularly in its use as a marine bunker fuel, it is essential that the knowledge and experience is publicised to new participants in the LNG industry.SIGTTO and SGMF have jointly issued the following document to provide a description of all guidance available and sufficient details. In the onset, I was explicit with you propecia before and after has changed my existence. It has become much more fun, and now I have to run. Just as it is fabulous to sit.

SIGTTO guidance for the prevention of Rollover in LNG ships

 SIGTTO has issued a paper to inform and advise the owners and operators of LNG carriers about the issues surrounding rollover.“Rollover” refers to the rapid release of LNG vapour that can occur as a result of the spontaneous mixing of layers of different densities of LNG in a storage or cargo tank. A pre-condition for rollover is that stratification has occurred, ie the existence in the tank of two separate layers of LNG of different density. The possibility of a sudden release of large amounts of vapour and the potential over-pressurisation of the tank resulting in possible damage or failure is recognised by the major design codes. EN 1473 - ”The design of onshore LNG terminals” and NFPA 59A - “Standard for the Production, Storage and Handling of LNG” both require this phenomenon to be taken into consideration when sizing relief devices. Whilst the relief valves may prevent damage to the tank, LNG vapour is not only flammable and heavier than air on release, but a valuable commodity and a potent greenhouse gas and therefore venting should be avoided whenever possible.Figure below shows an LNG tank without stratification. Methane evaporates from the surface, which cools due to loss of latent ...

SIGTTO issues LNG Shipping at 50

SIGTTO has announced the publication of  LNG Bunkering at 50. The publication marks the 35th and 43rd anniversaries of the Society of International Gas Tanker and Terminal Operators (SIGTTO) and the International Group of LNG Importers (GIIGNL), respectively.  The LNG industry has an exceptional story to tell and LNG Shipping at 50 contributes to the telling of that story. The publication starts with a review of the early days to show how the industry developed the innovative solutions needed to ensure the safe transport of LNG by sea. The articles in this section then describe how these solutions werethen continuously improved upon as more countries turned to seaborne natural gas imports to meet their energy needs. Safety is the No 1 priority in the LNG industry and the safety regime section of the magazine examines the cornerstones that underpin an unparalleled safety record. Quite aside from the IGC Code and the work of SIGTTO and GIIGNL, there are the contributions of class, training establishments, vetting programmes and escort tug services.

Recent gas-related developments at IMO and EU

Clarification is being sought for steam turbine LNG carriers in North and Baltic IGC Code updateSubject to some editorial clarifications, the draft revised International Gas Carrier (IGC) Code is scheduled for adoption at MSC 93 in May 2014, with a corresponding entry-into-force date of January 2016. The revised IGC Code will not be retroactive, and will apply only to vessels built after the entry-into-force date.IGF Code updateDevelopment of the International Code for Ships using Gas or other Low Flash-Point Fuels (IGF Code) continues to be progressed via correspondence group (CG). The primary focus of the CG remains the use of LNG as marine fuel, and although the CG is also addressing methyl alcohol and lowflash diesel fuels, that work will not delay the Code. Recent IMO sub-committee work has looked at the location of LNG bunker tanks (Ship Design & Construction Sub-committee) and STCW training requirements (Human Element, Training & Watchkeeping Sub-committee).Realistically, the IGF Code is at least 12 months behind the IGC Code, as the drafting group is not scheduled to meet until September 2014. IMO appears to be looking to fast track the IGF Code, with a target adoption date of spring 2015 and a resulting entry-into-force date ...
