Abstract

A pad for an subsea installatin in connection with petroleum-related drilling operations, in which a flexible mat (10), or a number of flexible mats (10), arranged to prevent the whirling up of bottom sludge, is placed underneath the subsea installation (14), or around the subsea installation (14), and where the mat (10), or mats, cover an area of the ocean bed (12) which is larger than the installation (14) which is placed on the ocean bed (12).
