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.

    Marine equipment like oil drilling rigs, oil tankers, oil risers, mooring systems, pump systems, anchors, underwater pipelines, hydroelectric systems and off-shore wind farms must be designed properly to withstand the forces at work in a marine environment, including wave action, tidal forces, high winds, variable temperatures, high pressures and inclement weather. Failure to properly compensate for any of these forces the design of marine equipment can lead to increased maintenance costs, premature failures, environmental damage or even accidents and injuries.

    Hydrodynamic analysis can be used to test the design and function of such equipment in simulated conditions that reliably mimic real-world scenarios, allowing any flaws in the design to be corrected before production and eliminating many of the costs involved in development and testing. It can also be used to evaluate existing designs or to determine an exact point of failure after a marine accident.

    To perform a comprehensive hydrodynamic analysis, experts with plenty of experience in the marine industry are required, as well as specialized software and equipment. It is typically more cost-effective to have a professional perform a hydrodynamic analysis than make the investments in equipment and personnel necessary to do it yourself.

  • How can I benefit from hydrodynamic analysis?

    Published by Bill Stewart on October 13th, 2015

    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.
