GTT receives an approval in principle from Bureau Veritas for “shear-water”, a new concept for a ballast-free LNG bunker & feeder vessel

GTT has been awarded a new approval in principle from Bureau Veritas, for the “Shear-Water” concept, a new ballast-free LNG bunker and feeder vessel.

The majority of merchant vessels worldwide use ballast water when they are empty or partially loaded in order to maintain seaworthy conditions. Therefore, a considerable quantity of ballast water is carried by ships every day.

Even when ballast water is treated, there is a risk of transferring harmful aquatic organisms and pathogens from one area to another. The solution developed by GTT eliminates this risk completely. In addition, removing the ballast water treatment system also reduces the energy consumption and CO2footprint of the vessels. GTT has been developing an approach to eliminate altogether the requirement for ballast water.

The GTT “Shear-Water” concept is based on the currently proven vessel of 18,700 m3 capacity with two membrane tanks. The design also features a new hull shape, in a “V”, which differs from the standard square shaped mid-ship sections traditionally used for LNG carriers.

An exhaustive testing campaign has been carried out at the HSVA Hamburg tank test facility in connection with power-speed, maneuverability and sea keeping. A sloshing test campaign has also been carried out by GTT to ensure the technical feasibility of the project: the excellent results obtained helped approve the concept.

GTT and Bureau Veritas play an active role globally to support safer and cleaner shipping. For many years both companies have been involved in significant developments including innovative LNG bunker and feeder vessel designs, as well as dedicated systems for this specialized and growing market segment.

Philippe Berterottière, Chairman and CEO of GTT, said: “We are proud to have developed “Shear-Water”, an innovative ballast-free design for LNG bunker and feeder vessels. This new technological solution allows a reduction in investment and operating costs, simpler operations as well as a reduction in corrosion supporting a longer service life. Obtaining this approval by Bureau Veritas constitutes recognition of the ecological relevance and performance of our technological solution.”

Mathieu De Tugny, Vice-president of Bureau Veritas said: “Bureau Veritas has given approval in principle to this new design, which has clear performance and environmental benefits: delimination of the need for ballast water treatment systems and equipment; easier maintenance of the void spaces surrounding the cargo, and reduced propulsion power requirements. Bureau Veritas has monitored and reviewed all the test results performed to support its approval in principle.”

The gas processing/LNG sector is investing in new technologies to mitigate carbon emissions from both operations and its supply chain.
Industry Focus: Maximizing the performance of your ETRM system
-Teresa Kroh, Brad York
Energy trading and risk management (ETRM) systems are vital for the support of business processes associated with trading energy commodities such as crude oil, refined products, natural gas, natural gas liquids (NGLs) and electric power, as well as facilitating the movement and delivery of those energy commodities and associated risk management activities.
Sustainability
-Oz Rodriguez, Catriona Penman
More than 100 participating countries at the 26th UN Climate Change Conference of the Parties (COP26) signed the Global Methane Pledge, in which they agreed to take action to reduce methane emissions at least 30% by 2030 vs. 2020 levels.


Optimizing Gas Distribution: Accounting for Changeovers, Regulators, and More

Gas distribution systems are critical to the effective operation of many industrial facilities around the world. Despite the importance of these systems, however, opportunities to improve their performance and cost-effectiveness are often missed or misunderstood. Increasing changeover pressure may seem like a good way to improve system flow, for example, but it often does so at the expense of bottled gas. Adding regulators may help you control supply pressure, but it also adds cost to your system. So, how do you know what the ideal gas distribution setup is for you?

Attend this webinar to:

  • Gain a basic understanding of the fluid dynamics that affect pressure control in gas distribution systems, learning to interpret flow curves and recognize phenomena like lockup, droop, and supply pressure effect (SPE)
  • Learn how inlet pressure affects regulator performance and when to specify certain regulator types and configurations to effectively control gas system pressures

Understand the inherent trade-offs between gas utilization and flow capacity and how to select both the right changeover pressure and automatic changeover panel design for your operations.
