Lloyd's Register, Shell, and GTT have jointly undertaken the examination of the design of hybrid electric ships with a capacity of 200,000 cubic meters for transporting liquefied natural gas (LNG). This project aims to enhance LNG transportation efficiency and reduce greenhouse gas emissions in the energy sector.
Project Goals and Technologies Used
The project will investigate how to utilize advanced technologies such as GTT's NEXT1® cargo containment systems and hydroelectric systems to improve the efficiency and flexibility of LNG ships. By integrating these two technologies, the main objective is to increase loading capacity, optimize operations, and respond to the changing needs of the energy industry.

Safety Development and Assessment
As part of this project, collaborating partners will develop and validate the safety of hydroelectric systems on the ships. The focus will be on system architecture, redundancy philosophy, and battery integration. The commercial evaluation of this technology will also be based on the total cost of ownership (TCO) model. Additionally, the integration of GTT's NEXT1® cargo containment technology will be examined as part of the overall ship concept.
This project will also establish requirements and technical guidelines for the application of hydroelectric systems in LNG ships to provide a better technical understanding of this technology.
Expert Opinions
Constantinos Chatzis, Global Gas Director at Lloyd's Register, stated: "The industry is under increasing pressure to move more energy with lower emissions and greater operational flexibility. Concepts for larger capacity ships are being explored, and this project will examine how hydroelectric and cargo containment technologies impact their technical and operational performance from a TCO perspective."
He added: "By gathering expertise from across the LNG value chain, we are developing a technical foundation that can aid in further evaluating LNG ship concepts in the future."
