摘要：
A method of forming a mudline cellar includes positioning a mudline cellar forming member on a seafloor surface. The mudline cellar forming member includes an outer surface and an inner surface that defines an inner cavity. The method further includes driving the mudline cellar forming member into the seafloor surface, and excavating the inner cavity of the mudline forming member to establish the mudline cellar.
