A typical offshore platform
has several major components. The “DECK” is
the uppermost part of the structure located above the
sea
surface. The deck is
welded to the “JACKET” which extends from
about 10 ft above sea level all the way down to the sea
floor. Steel
pilings are driven through
the hollow corners of the jacket into the sea floor to
depths that may exceed 100 ft. It is these pilings that
secure
the platform to the sea
floor and enable it to withstand the forces of winds and
seas. Demex International Inc. severs these pilings between
15 and 20' below mudline.
