SIGTTO Recommendations for Valves on Liquefied Gas


Carriers updated The Society of International Gas Tanker and Terminal Operators (SIGTTO) has published the updated version of the Recommendations for Valves on Liquefied Gas Carriers.


The document presents an overview of the existing valve design standards and summarizes the essential requirements. It offers recommendations aimed at addressing specific issues to enhance safety and promote environmental protection.


This new document consolidates and replaces two previous editions: - The Selection and Testing of Valves for LNG Applications (2008) - The Selection and Testing of Valves for LPG Applications (2012)


This update takes advantage of advancements in safety philosophy, technological improvements, and lessons learned, and the recommendations pertain to carriers transporting liquefied petroleum gas (LPG) and liquefied natural gas (LNG). In this document, LPG refers to liquefied gas cargoes carried within the temperature range of 0°C to -104°C, including substances like ammonia and ethane. The term LNG is used for cargoes transported at an approximate temperature of -162°C.


While the guidance in this document is useful for cargoes that might react with valve components, additional considerations may be necessary due to the nature of the product.

SeaBubbles hydrofoil enters commercial


service in France The Bubble is being used as an electric passenger ferry on Lake Annecy as part of a two- month pilot project. French start-up SeaBubbles has announced that its ‘flying’ hydrofoil boat, the Bubble, has entered commercial service as part of a pilot project on Lake Annecy in France.


The new mode of transportation will offer a


regular passenger service in collaboration with the Grand Annecy conurbation. Operating eight rotations per day for a period of two months, the initiative is projected to save an impressive 100 tonnes of CO2 emissions on Lake Annecy, SeaBubbles claims.


The Grand Annecy, renowned for its picturesque landscapes and commitment to environmental conservation, has taken a significant step towards sustainable mobility by introducing the electric shuttle service on France’s prime lake. The initiative aims to combine the region’s natural attractiveness with a responsible transport mix that includes free seasonal buses, self-service bicycles, and now, SeaBubble hydrofoil boats.


The four-seater SeaBubble employs an electric propulsion system and hydrofoil wings to lift the vessel out of the water, significantly reducing drag and enhancing speed. Passengers can anticipate an exhilarating journey as they glide smoothly across the water, offering breathtaking views of the surrounding landscapes.
