Abstract

The present invention concerns a method for applying insulation to a combined cylindrical tank for storage of liquefied gas. One or more layers of a polymer foam (2) are sprayed onto the exterior surface of the tank shell (1). Crack barriers (4) are mounted on top of certain layers of the polymer foam (2), wherein the crack barriers (4) are anchored to the exterior surface of the tank shell (1). The invention also concerns a corresponding combined cylindrical tank for storage of liquefied gas, as well as the use of such a combined cylindrical tank for storing and/or transporting a liquefied gas.

IPC Classes  ?

• F17C 3/04 - Vessels not under pressure with provision for thermal insulation by insulating layers
• F17C 3/02 - Vessels not under pressure with provision for thermal insulation

Abstract

The invention relates to a marine vessel cryogenic barrier which is formed of a plurality of individual panels, each panel being arranged to align with an adjacent panel on an inner surface of a hold space of a marine vessel and comprising a single coupling means at the centre of the panel and an impervious layer on a surface of the barrier facing the hold space.

Abstract

The invention relates to an insulation arrangement for a liquefied gas carrying ship wherein the ship has a primary barrier for containing a liquefied gas and a hull, and where the hull is spaced from said primary barrier to define a void between the hull and primary barrier. The hull is insulated with an insulation layer, said layer comprising a plurality of individual tessellating insulation panels.
