LNG Fuel Tanks_Pressure and Temperature Strategies for Gas Fuelled Vessels (TGN17-02)

LNG Fuel Tanks_Pressure and Temperature Strategies for Gas Fuelled Vessels (TGN17-02)

  • ISBN: 978-1-7398703-9-3

The ongoing goal of Working Group 17 is to provide operationally focused guidance based on lessons learnt in the adoption and ongoing use of LNG as a marine fuel. Working Group 17.2 was formed with a diverse group of members across the whole spectrum covering new market entrants who are taking ownership of a gas fuelled ship for the first time to experts with decades of experience. This Technical Guidance Notes again demonstrates what can be achieved when different individuals and organisations come together and collaborate with a single goal. I am extremely proud and feel privileged to have Chaired this working group in delivering this first of a kind guidance. The concept of tank temperate and pressure management and in particular boil off gas management is a like an iceberg. Whilst on the surface the idea is simple, the underlying understanding and issues are complex made even more so by the diverse nature of the vessels and operating modes reflected by the maritime fleet outside of LNG Carriers. This guidance note provides operational guidance primarily aimed at this organisation operating gas fuelled ships to better understand the challenges and potential solutions for operating gas fuelled vessels. It also provides useful information on how to mitigate some of these challenges starting at the design stage. PRE-ORDER NOW

LNG as a marine fuel - A Bunkering Compatibility Assessment Methodology (TGN19-01)

LNG as a marine fuel - A Bunkering Compatibility Assessment Methodology (TGN19-01)

  • ISBN: 978-1-7395354-0-7

Compatibility assessments are common in the conventional LNG carrier industry for Ship-to-Ship and cargo terminal operations, but the assessments for LNG bunkering operations differ significantly and require standardisation. The constantly increasing fleet of GFVs has imposed challenges for the bunker suppliers to process the required technical information to ensure compatibility with their bunkering facilities. Similarly, technical managers of GFVs are often asked to provide the same information to multiple suppliers in a variety of formats, resulting in a growing workload for both suppliers and receivers. This is why the standardisation and simplification of the process is essential. Bunkering Compatibility Assessment Methodology provides clear guidance on compatibility and the assessment process to produce time efficient and safe assessment results.

BASiL Gas Dispersion Tool - 3 x Reports

BASiL Gas Dispersion Tool - 3 x Reports

BASiL (Bunkering Area Safety information LNG) is SGMF’s automated LNG gas dispersion tool. It can be used to manage bunkering on a consistent basis through the definition of a safety zone that depends on the type of bunkering operation being undertaken. Access to this tool is now available to non-Members. A copy of the publication ‘Recommendation of Controlled Zones during LNG bunkering (ISBN: 978-0-9933164-8-7) will be sent by courier as part of this purchase. It is strongly recommended that users of BASiL read and fully understand this publication as well as the BASiL User Guide before running any reports. For this reason there is a delay of 7 working days from the date of purchase before you can access the tool via this website.

Contractual Guidelines - Quantity and Quality

Contractual Guidelines - Quantity and Quality

  • ISBN: 978-0-9933164-1-8

This publication provides an overview of the custody transfer process of LNG to marine vessels. This guide describes the variables required to be measured for the main marine engine types. The later sections of this guide describe the proven techniques available for measuring both LNG quantity and quality. . It describes several methods, all of which provide sufficient accuracy and auditability to support the custody transfer process. Its aim is to educate and inform and not to be prescriptive.

LNG as a marine fuel - Safety and Operational Guidelines - Bunkering (Version 3.0)

LNG as a marine fuel - Safety and Operational Guidelines - Bunkering (Version 3.0)

  • ISBN: 978-1-9996669-7-2

This 2021 edition is taking a new and holistic approach to LNG bunkering. The reader is taken through a journey starting from the Design stage of the vessel and the supply bunkering facility, via the Planning and Preparation stages of the bunkering location and operations to be completed by the fuelling Operational stage of the of an LNG-fuelled vessel. Along each stage recommendations are provided to all the stakeholders involved in the bunkering of ships with Liquefied Natural Gas (LNG) with the focus on ensuring that gas fuelled ships are bunkered safely, reliably, efficiently and to prevent undesirable fugitive gas emissions during operations.

Simultaneous Operations (SIMOPs) during LNG Bunkering

Simultaneous Operations (SIMOPs) during LNG Bunkering

  • ISBN: 978-0-9933164-7-0

A new publication that looks at undertaking typical ship operations in port whist transferring fuel at the same time (SIMOPS). Whilst it is imperative that safety is not compromised when using LNG, it is also important that other operations can be undertaken so as to allow efficient and in some cases, improved efficiencies in port. This publication looks at the issues involved and describes clearly the process of how the risks can be managed.

Recommendation of Controlled Zones during LNG bunkering

Recommendation of Controlled Zones during LNG bunkering

  • ISBN: 978-0-9933164-8-7

The publication details a leading piece of work related to how to effectively determine the location and size of so-called controlled zones around the bunkering equipment itself.

Bunkering of Ships with LNG - Competency and Assessment Guidelines version 2.0

Bunkering of Ships with LNG - Competency and Assessment Guidelines version 2.0

  • ISBN: 978-0-9933164-5-6

The aim is that the suggested guidelines can be used by any individual, organisation or authority, on either side of the transfer process to identify what tasks will be conducted by themselves, their personnel, or within their scope and hence be able to identify the knowledge, understanding and competencies that they require.

Operation of ships with Liquefied Natural Gas (LNG) - competency and assessment guidelines

Operation of ships with Liquefied Natural Gas (LNG) - competency and assessment guidelines

  • ISBN: 978-1-9996669-5-8

This document focuses on all the activities relating to the preparation, storage, handling and use of gas as a fuel – from the storage tank through to delivery to the consumer – and the competencies required of those personnel engaged in undertaking the related tasks. It therefore covers the full scope of competencies that we believe a skilled engineer and supporting team need to have to be able to operate the gas fuel system through the complete voyage cycle (from dry-dock to dry-dock). It therefore goes beyond the scope of the IMO’s Standards of Training Certification and Watchkeeping (STCW) and should be used accordingly.
