- GTT and HD Hyundai Heavy Industries launched two JDPs to improve LNG carrier design and performance.
- One project introduces a trapezoidal forward cargo tank for better hull fit and increased capacity.
- The second project focuses on a flush deck liquid dome to enhance ergonomics and simplify piping.
- Both companies aim to meet evolving maritime requirements through practical, energy-efficient innovations.
GTT has signed two Joint Development Projects (JDPs) with HD Hyundai Heavy Industries (HHI) to improve LNG carrier designs. This partnership focuses on optimizing membrane-tank integration to boost onboard ergonomics and enhance vessel performance. The projects demonstrate both companies’ commitment to creating practical solutions that address the changing technical, economic, and environmental demands of the maritime sector.
Focus Areas of the Joint Development Projects
The two JDPs will target key innovations in LNG carrier design:
Convergent trapezoidal cargo tank No. 1: This forward tank concept features a convergent trapezoidal shape combined with GTT’s Mark III membrane system. Its unique geometry offers better hull alignment than traditional constant-section tanks, maximizing cargo capacity.
Flush deck liquid dome: An innovative flush deck liquid dome will be positioned where the membrane tank meets the cryogenic piping. This design improves trunk-deck ergonomics, simplifies onboard piping, and makes maintenance easier.
Philippe Berterottière, Chairman and CEO of GTT, stated that these projects reflect a shared ambition to develop practical innovations that meet the environmental, economic, and technical needs of LNG maritime transport. He emphasized the importance of advancing technology and sustaining innovation momentum.
Ryu Hong-Ryeul, Head of Technology at HD Hyundai Heavy Industries, expressed satisfaction with the collaboration, highlighting how their combined expertise will drive vessel innovations that boost energy efficiency and ergonomics while supporting the growing demand for LNG carriers.
