The purpose of the insulation system is to minimize boil off rate by limiting the heat ingress. LNT Marine offers alternative insulation systems for IMO type C tanks. All with unique properties for use in different environments with different surface materials to optimize the function of the system. A LNG deck tank and a LNG cargo tank in a controlled atmosphere are exposed for very different condition and requires different properties of the surface for optimal function.
All systems are fully bonded spray foam insulation systems tailormade and optimized for the client’s needs and have the same basic thermal insulation design based on spray foam with variable densities and two layers of imbedded crack barriers. The insulation is flexible enough to follow the tanks contraction and expansion. There is no space for accumulation of moisture between containment structure and insulation, and there are no through-going joints. This has proven to be the most efficient insulation system and requires no maintenance.
LNT Marine offers spray foam insulation systems for newbuildings, repairs and conversion/upgrades.
