Bunnrammekonstruksjon for boring av olje- og gassbrönner under havflaten

摘要

There is disclosed a subsea foundation/template construction comprising a polygon, preferably square central body (1), to which body (1) there exists at least one horizontally hinged arm (2) so that the arm(s) (2) may be pivoted from a mainly vertical to a mainly horizontal position over an angle of about 90 DEG . The present foundation/template construction comprises parts which may be assembled on the drilling site and which may be submerged through a conventional moonpool of a drilling rig without the need for special vessels for transporting or mounting the foundation/template.
