Stewart Technology Associates are experts in mechanical and geographical technology of the offshore industries seakeeping analysis processes. This is the essence of the STA marine strategies. This company has brought Jack-ups and liftboats to aid marine offshore businesses for years. It also provides information that leads to correct calculations in the preparation of shipping conditions.

As an expert in the field the president of this resourceful technology company, Mr. W. P. Stewart, is a leading person in the mariner field. Called upon in events concerning sea related accidents, Bill Stewart is a seasoned expert. This company developed the jack-up simulator, both physical and software simulators and provides the service of oil spill clean up. The company is involved with risk assessment for mariner equipment.

Established in 1986, STA is qualified in geotechnical technology. The company’s devices have improved the safety and methods of factoring mooring analysis for vessels and the use of training simulators. This company’s equipment is used to further the preparedness of water safety agencies in many countries. Seakeeping analysis has been a part of Mr. Stewarts training for over twenty years and remains a part of his expertise. This Houston based firm provides offshore training equipment for a long list of mariner companies.

Using the companies design and analysis services to improve sea operations this company caters to a number of clients around the globe, up grading the necessary software and equipment that keeps oil rigs and seafaring equipment moving. The mariner community is limited to a few experts and Bill Stewart of Stewart Technology Associates happens to be one of them. Developing tools that propelled shipping into a better industry, the jack-up simulator and the ballast control simulator, this company is standing on the forefront of mariner innovations.

Stewart Technology Associates has acted as a marine specialist making pipe/pump software packages, these items are updated by the company. Mariner developers around the world use the technology developed by STA, with Jack up simulators distributed as a separate item or connected with the full simulator.

Heavily qualified in Seakeeping analysis, STA has the ability to effectively determine if a vessel is able to maintain its integrity in the sea environment. People trained to deal with oceanic conditions are trained on simulators designed by Stewart Technologies Associates.

Ships and barges are a part of the scenery today out on the sea but these water vessels need trained people and strong materials to keep them afloat. This company has developed a strategy that test equipment, trains people and keeps equipment sea worthy, allowing them to test and calculate a vessels seaworthy ability before it is challenged by the oceans fury.

OrcaFlex Software Has Multiple Talents

Technology plays an important role in offshore and marine industries. OrcaFlex software has multiple talents to help with structural dynamics and hydrodynamic analysis of structures.

Designed by mechanical and software engineers, naval architects and mathematicians, this software was developed by Orcina Ltd. professionals to analyze diverse marine systems.

Some Features of This Software

This top-rated software assists in the design of the following marine systems.

  • Riser systems;
  • Mooring systems for offshore structures;
  • Installation plans for diverse scenarios;
  • Towed offshore systems; and
  • Defense systems, marine renewables and seabed stability solutions.

With its incredible power combined with a wonderful GUI, this software package is the optimum marine services program available today. Its sister software, OrcaLay and OrcaBend work in concert to provide pipe lay and bend stiffener design and analysis.


The software helps with design and installation of production risers. Needed to transfer fluids to and from vessels, these conductor pipe systems are essential to the efficiency of deep water production systems.

OrcaFlex software also offers assistance with both types of drilling risers. When designing and installing marine drilling risers, which typically are used by floating drilling vessels, and tie-back risers, used by fixed drilling platforms in conjunction with surface blowout preventers, help anchor either single high-pressure pipes or sets of concentric pipes.


Also known as single buoy moorings, single point moorings keep one or more tankers stationary while offloading gas or liquid from platforms. The software allows users to plan how to deploy the buoys for maximum efficiency.

CALM (Catenary Anchor Leg Mooring) buoys include multiple legs (tethers) and a turntable, allowing vessels to “weathervane” while accepting the transfer of fluids from platforms. Mooring tankers to these buoys gives platforms more flexibility to transfer gas or fluid in varied weather and sea conditions.

The software’s excellent GUI, graphically displays the alternative deployment options to most mooring designs, allowing users to visualize, analyze and evaluate the best choice for installation. Instead of costly trial-and-error methods, OrcaFlex shows the variety of available options for deployment.

Other Applications

Along with displaying multiple options for the vital deployment of risers and moorings, OrcaFlex offers other applications, making it one of the most versatile programs in the marine industry. Other valuable applications include the following items.

  • Installation evaluation and analysis;
  • Buoy system options;
  • Hose variations, including under-buoy, offloading and floating hose systems;
  • Defense issues, including minesweeping research and helicopter landing options; and
  • Renewable energy systems, including wave power and wind farm modeling.

It is evident that OrcaFlex software helps companies and consultants plan, design and deploy the primary marine systems applying to both vessels and offshore platforms. Stewart Technology Associates specializes in using this technology to deliver our outstanding marine consulting services.

Our extensive expertise, combined with this powerful software package, gives us the tools to design solutions to most marine-related issues. We also feature forensic analysis to identify prior problems or create evidence for expert testimony responsibilities. Combined with our riser and mooring experience, we offer a wide variety of efficient solutions for a myriad of structural and offshore marine systems.
