Lloyd\u2019s Register (LR) has issued an Approval in Principle (AiP) to GTT for new elongation criteria applicable to LNG carrier hulls fitted with the NO96 cargo containment system.<\/p>\n
The approval confirms that GTT\u2019s revised criteria governing allowable hull deformation beneath the NO96 membrane and insulation system meet LR\u2019s classification requirements and relevant international regulations. The assessment covered operational, thermal and hull-induced loads to ensure continued structural integrity of the containment system.<\/p>\n
Developed as part of GTT\u2019s ongoing innovation programme, the revised elongation criteria are intended to give designers greater flexibility in hull structural design while maintaining established stress limits, fatigue margins and membrane performance.<\/p>\n
LR\u2019s review included detailed structural and hydrodynamic analysis based on a representative LNG carrier design. This examined compatibility across NO96 variants and alignment with applicable load cases and hull geometries.<\/p>\n
The updated criteria enable more efficient structural optimisation for NO96-equipped vessels, with potential benefits for lightship weight while maintaining safety and regulatory compliance.<\/p>\n
NO96 remains one of the most widely used cargo containment systems in the LNG fleet and is also relevant to complex, high-specification gas carriers and other marine vessel designs where structural assurance is critical.<\/p>\n
Constantinos Chaelis, Global Gas Segment Director, Lloyd\u2019s Register<\/strong>, said:\u00a0\u201cThis approval is about giving confidence at an early stage. Our review confirmed that GTT\u2019s updated NO96 elongation criteria remain within established safety margins while allowing designers greater flexibility.<\/em><\/p>\n \u201cThis kind of technical validation is essential as vessel designs become more optimised and structurally demanding.<\/em>\u201d<\/p>\n Fran\u00e7ois Michel, CEO, GTT<\/strong>, said: \u201cLloyd\u2019s Register\u2019s Approval in Principle confirms the technical robustness of the latest NO96 developments. These enhanced design criteria provide greater flexibility for ship designers while preserving the highest standards of safety and membrane integrity.<\/em>\u201d<\/p>\n About Lloyd\u2019s Register<\/p>\n Trusted maritime and energy sector advisors, partnering with clients to drive performance across the ocean economy.<\/p>\n Lloyd\u2019s Register (LR) is a global professional services group specialising in marine and offshore engineering, technology and digital solutions.
