GTT Inside #31 - July 2024


Message from Jean-Baptiste Choimet, CEO of GTT

JB Choimet GTT

Since June 12th, I have had the honour of serving as the Chief Executive Officer of GTT. I would like to take this opportunity to express my deep appreciation for everything that has been achieved so far and, more importantly, for the strong relationships that have been built over the years between GTT and its various partners.

My commitment is to maintain and further these trustworthy relationships by supporting licensed shipyards in building ships with our technology, assisting ship-owners using our tanks, and collaborating with charterers who trust our technology for transporting their cargo. Additionally, I am dedicated to continuing our efforts in innovation.

In this issue of GTT Inside, we highlight some of our recent innovations. Firstly, we have improved our sump designs to facilitate construction in shipyards, thereby reducing their costs. You will also find an article on ULEC, where we, together with our partners, have developed a design for a 150,000-m3 ethane carrier that significantly enhances the economics of ethane shipping. Lastly, we have secured General Approval for Ship Application (GASA) from both Lloyd’s Register and Bureau Veritas for GTT NEXT1, signifying the official commencement of this new technology's implementation.

I look forward to meeting with you to discuss these innovations in more detail, along with many other exciting developments.
 

A Major Qualification Step for the GTT NEXT1 Cargo Containment System

In early June 2024, GTT achieved a significant milestone with the award of key approvals from Bureau Veritas and Lloyd's Register for its GTT NEXT1 LNG cargo containment system. These approvals mark a pivotal moment for GTT, affirming the system's compliance with international standards.


Future Proofing Ultra Large Liquefied Ethane Carrier Design: Leveraging LNG-Ready Advanced Membrane Technology

As the ethane market matures, industry stakeholders are increasingly focused on transporting larger volumes of ethane across the oceans. This trend has led GTT to develop designs for vessels with greater cargo capacities, particularly a 150,000m³ Ultra Large Ethane Carrier (ULEC). This larger carrier enables a reduction of shipping cost per cubic meter while enhancing transported cargo volumes and improving petrochemical plant output. From an environmental perspective, large carriers also benefit from a reduced carbon footprint per cubic meter transported.


Enhancing LNG Pump Efficiency: GTT's Innovations in Sump and Bucket Solutions

The pumpable volume of liquefied natural gas (LNG) within cargo and fuel tanks plays a pivotal role in vessel design. For LNG carriers, it dictates the cargo quantity deliverable without compromising ballast voyages, while for LNG-fuelled vessels, it influences the navigational range achievable based on specific main engine consumption rates.
 


Enhanced Operations and Efficiency: Introducing GTT’s ‘Ballast-Split’ Design for LNG Carriers

GTT’s innovative 'Ballast-Split' design involves dividing ballast tanks to effectively reduce liquid motion and optimize boil-off rates. By strategically partitioning these tanks, GTT aims to address the challenges posed by partial cargo loading, particularly in the 10 to 40% tank height range where significant loads on the containment system are encountered. Through this article, we delve into the rationale behind the 'Ballast-Split' design, its operational implications, and its potential to set new standards for LNG carrier performance.
