Technip
designs, constructs and installs in
deep or shallow waters, fixed and floating
platforms for the production and processing
of oil or gas. The floating platforms
are anchored at the offshore production
site and are mainly of two types: those
designed for developments with subsea
trees, and those using dry trees.
Technip
is experienced in the engineering
and project management of fixed and
floating surface facilities and
offers
unique technological solutions such
as floating production and storage
systems, self-installing drilling
platform decks not requiring the
use
of cumbersome separate installation
equipment such as floating cranes
(Unideck TPG) and the streamlined
platform for exploiting marginal
fields
(MOSS).
The
TPG 500 is a self-installing fixed
platform which is constructed, equipped
and tested onshore and then towed
to site. Once on site, the platform’s
legs are jacked down to the seabed
up to 500 feet below the surface (suitable
for many North Sea fields) and the
hull is subsequently raised into its
final position. Although the TPG 500
is a fixed and not floating structure,
the installation can be reversed and
the platform re-installed at a new
site. In 2000, we delivered our second
operational TPG 500 platform (For

The
SPAR is a deepwater
drilling and production platform.
The structure comprises a vessel
with
a circular cross-section that sits
vertically in the water and is
supported
by buoyancy chambers at the top and
stabilized by a midsection structure
hanging from the hard tanks. If necessary,
stability may be supplemented
by solid
ballast placed in compartments at
the keel. The vessel is held in
place
by a taut catenary mooring system,
providing lateral station keeping.
The SPAR platform uses ‘‘dry-tree’’
technology, where the wellhead equipment
is principally located on the platform
rather than on the seabed, reducing
the cost and time involved in common
maintenance work. (For

In addition to the large fixed and
semi-submersible platforms
described
above, Technip is also active
in the design and installation
of
Floating Production, Storage and
Offloading Systems (FPSO).
These systems, in
which production and storage facilities
are housed in a ship hull,
are appropriate
for developing deposits in deep or
shallow waters, in order to
start
early production for operators’
needs, and also adapted to areas
where few subsea infrastructures
exist such
as in West Africa or offshore Canada,
in Newfoundland. (For
