The Irish Sea Pioneer, a 4-legged jack-up was designed by STA in 1996 and built at Bollinger Shipyard, Louisiana, for Halliburton. STA provides jack-up analysis and jack-up design and review services. STA provides mooring design and analysis services for pier and quayside moorings, single point moorings (SPMs), multi-buoy moorings (MBMs), spread moorings in shallow and very deep waters. STA has used OrcaFlex for design and analysis of wave power systems, and proprietary tension-leg platform-mounted wind turbines. STA has assisted clients with wind farm installations using liftboats, jack-ups and crane barges. The MRE Committee has been producing a new document for Civil Engineer involved with MRE projects. The ASCE COPRI Marine Renewable Energy Committee was formed in 2009 and Bil Stewart was appointed Chairman. View SUT Offshore Renewables presentation by Bil Stewart in September, 2018. STA clients have been increasingly interested in renewable energy, particularly from offshore fixed and floating wind farms, in-stream hydrokinetic devices and wave energy converters. This case involved an understanding of naval architecture, mechanical technology and geotechnical technology, all contributing to an unusual stability failure.
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.Īn 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. OrcaFlex is used by STA for DRILLING RISER ANALYSIS and for DYNAMIC MOORING ANALYSIS.
STA has other in-house tools for cable dynamics, and a range of bespoke STA software offered for sale. OrcaFlex is generally the software of choice for riser design and riser analysis, mooring design and dynamic mooring analysis, single point moorings, top tensioned risers, flexible risers, drilling and production risers, steel catenary risers and cable dynamics problems in general. We specialize in advanced applications in Excel with extensive use of graphics and VB macro coding. STA undertakes structural dynamic and hydrodynamic analysis of many structures and systems using a variety of technology software tools. We de-risk offshore and marine projects using advanced simulation and analysis. Stewart Technology Associates (STA) founded in 1986, provides a wide variety of services in the offshore and marine industries. Structural, Marine and Offshore Specialists
