How can I benefit from hydrodynamic analysis?

Published by Bill Stewart on April 3, 2016

The ever-increasing search for new and richer deposits of oil has led to oil platforms being constructed further and further offshore. These new offshore platforms have to reach unprecedented depths and have to do so safely with an eye for how the hydrodynamic forces at and below the water's surface will impact rig equipment.

Hydrodynamic analysis is an exciting oil and gas software that's been designed to help improve rig constructions. Here are some of the ways hydrodynamic analysis could benefit your group:

  • Better platform design.
  • The offshore platform is continually being subjected to tidal forces, ocean currents, winds, and wave actions. Such constant pressure against and around its structural components can cause fatigue that may lead to serious failures. Hydrodynamic analysis helps model these forces to help you design better platforms capable of withstanding a given site's elemental forces.


  • Improved riser design.
  • Risers are a critical component of any offshore facility as they are what connects the oil well to the above surface platform and enables extraction to occur. Should risers fail, it could lead to an environmental disaster, workplace injuries, and potentially even a total rig explosion. Using hydrodynamic analysis will ensure that rigs are using the right type of design and components, whether flexible or rigid, for a given worksite. This improves safety, productivity, and reduces wasteful spending.


Are there any Hydrodynamic Analysis technology experts?

Hydrodynamic analysis invariably proves to be a series of complex puzzles requiring painstaking data collection and careful attention to detail.

What are the main issues that can be resolved by Hydrodynamic Analysis?

Stewart Technology Associates provides consultancy services for marine and offshore engineering. As the market demands more energy, off shore equipment must be moored in more complicated settings. Companies now push rigs further offshore. But, safe operating conditions cannot be sacrificed for more oil. Our team approach to hydrodynamic analysis combines diverse experience, theoretical knowledge and continuing education from plenty of ongoing projects. We know predictability and reliable performance serves the demand for production in the long term.

Stability and safety. Those issues are the bottom line. Mooring services rely on solid hydrodynamic analysis of anchoring, leg choice, platform selection and implementation. STA has been delivering excellent service for almost thirty years for marine and offshore companies. We offer more experience, general skills and dedication than all other firms in the offshore engineering consultancy industry. We provide nothing short of the highest quality of services for all of our clients. We offer the management skills, resources and the knowledge that you need when it comes to fulfilling every mooring requirement. We use only the most advanced resources and the best software to give you a virtually flawless design and completely accurate analysis. We are certain that our services will meet and even exceed your utmost expectations.

How can I benefit from hydrodynamic analysis?

Hydrodynamic analysis is an amazing tool used to gain insight into the behavior of water and liquids and how they impact ships and other maritime facilities. This centers upon the study of fluid in motion and provides key benefits to people involved in major scale projects like solving complex problems with offshore facilities. The following are just a few of the ways in which you might benefit from hydrodynamic analysis:

  • Building in challenging waters. Offshore companies frequently have to go in harsh conditions, where there can be either extreme depths or shallow, unpredictable waters (like in the Arctic). Hydrodynamic analysis provides accurate predictions of wave loads to enable the safer construction of offshore platforms. This includes giving accurate calculations of needed strength and fatigue capacity. 

  • Offshore pipelaying. Whenever you put down pipes, it's integral to know how the underwater forces will act against their installation and removal. Hydrodynamic analysis is especially beneficial for those needing to know how best to operate a powerful DP vessel through shallow water for safe pipelaying.

  • Harbor and mooring design.  Knowing how tides and special underwater forces will work against set mooring and harbor designs is one of the biggest benefits of hydrodynamic analysis. When putting in a mooring field near an offshore platform, it's the harbor master's responsibility to ensure that lift and drag factors won't cause boats to be pushed into precarious locations. This type of analysis ensures that harbor construction and the installation of a mooring field meets all standards and is capable of withstanding the worst of an area's storms and tidal fluctuations.
