Stewart Technology Associates (STA) founded in 1986,
provides a wide variety of services in the offshore and
marine industries.
STA undertakes structural dynamic and
hydrodynamic analysis
of many structures and systems using a variety of
engineering software tools.
Orcaflex is generally the
software of choice for riser design and
riser analysis, mooring
design and mooring analysis,
single point moorings
top tensioned risers, flexible
risers, drilling and production risers,
steel catenary risers
and cable dynamics problems
in general.
STA
is a US Agent for Orcina Software, including OrcaLay for

STA provides jack-up analysis
and jack-up design and review services.
The Irish Sea Pioneer, a 4-legged jack-up was designed
by STA in 1996 and built at Bollinger Shipyard, Louisiana,
for Halliburton. This vessel now works the Liverpool Bay
Project, UK. STA developed a jack-up analysis program, STA
JACKWAVE, beginning in 1987.
STA LIFTBOAT is a
similar program used by liftboat designers for preliminary
design of liftboats. The US Coast Guard also use it for
liftboat design reviews.
STA has proprietary software and designs for
marine training simulators used
for improving emergency preparedness of crews on jack-ups,
semi-submersibles, and liftboats. STA now helps US clients
with CE marking in conformance
with the 98/37/EC Machinery Directive.

Mr. Stewart has acted as an expert witness on many occasions,
providing expert testimony associated with
marine accident
investigation, mooring
failures, riser failure,
single point moorings,
liftboat design,
anchor analysis,
pile anchors, anchor failures,
suction pile failures, cable
dynamics, seakeeping
analysis, and marine collisions and capsize.
An interesting expert
witness marine litigation case involved a bottom-founded
barge that capsized while resting on-bottom of a lake in
relatively benign environmental conditions. This case involved
an understanding of naval architecture, mechanical engineering
and geotechnical engineering, all contributing to an unusual
stability failure.

STA clients have been increasingly interested in renewable
energy, particularly from wind farms and wave power systems.
STA has assisted clients with wind farm installations
using liftboats,
jack-ups and crane barges.
STA has used Orcaflex for
design and analysis of
wave power systems, and proprietary tension-leg platform-mounted
wind turbines.

They are the pipeline that transports the gas and oil from the ocean floor to the platform or oil rig for packaging or transport. The oil and gas is pumped up through the risers to the platform or boat where it is transported to be used by businesses.
