The platform has a vertical shaft wall in which the casing is supported and a first packing which seals between the casing and the shaft wall. Swingable claws releasably interconnect the upper tension leg element to the casing, and a second packing surrounds the upper tension leg element and releasably seals between the upper tension leg element and the shaft wall.
