Abstract

A device for preventing soil wash out during subsea drilling is shown and described, having means for retaining the soil around a sub sea anchor foundation (7). The means comprises at least, one flap member (7') hingedly (11) mounted adjacent to the lateral walls of a subsea anchor foundation (7) and adapted to receive a well bay insert (8). The flap member (7") is adapted to be in a substantially vertical position during the lowering to the seabed and remain in substantially horizontal position, parallel to the sea bed (2) during drilling operation and acts as a lid or a lock for physically holding the soil in position.
