GTT has received the Final Approval for its NO96 Super+ technology from classification societies Bureau Veritas, DNV and Lloyd’s Register.

The new NO96 Super+ technology is an evolution of the NO96 containment system maintaining its principal features, in particular the double Invar metallic membranes and the mechanical anchors fixing the insulation panels to the hull.

NO96 Super+ offers the advantage of reducing the heat ingress inside the tank by integrating insulating Reinforced Polyurethane Foam (R-PUF) panels instead of plywood boxes. Thermal performance is additionally improved by the addition of Glass Wool joints, inserted between adjacent foam panels.

With this innovation, GTT provides a solution to reduce the evaporation of the cargo, with NO96 Super+ guaranteeing ship-owners a daily Boil Off Rate (BOR) of 0.085% of volume for the current standard size design of LNG Carrier of 174.000m3.

Philippe Berterottière, Chairman and CEO of GTT declared, “As a result of these Final Approvals, GTT is able to offer its ship-owner and shipyard partners the new NO96 Super+ technology, an innovative containment system with a greatly reduced Boil Off Rate. Reducing Boil Off Rate is essential for the industry as ship-owners and shipyards face ever increasing economic and environmental challenges.”
