PDL our markets

PDL is internationally recognised as a leading authority in delivering advanced global analysis on increasingly complex engineering projects. Our engineers continue to drive innovation by establishing new procedures and methodologies that increase both the efficiency and cost-effectiveness of our client’s projects.

By using a variety of cutting-edge analysis tools, we are able to accurately model the inherently non-linear response of subsea equipment in both the time and frequency domain. Specifically, our engineers have a proven track record in the following areas:

 Rigid and Flexible Risers

 Rigid and Flexible Subsea Jumpers

 Mooring Systems and Sea-fastening

 Installation Analysis

 Drilling Risers

 Subsea Umbilicals

 Renewable Power Cables

 Vessel hydrodynamics

The use of industry-leading software, coupled with an expert knowledge of engineering principles, means that our engineers are able to provide robust solutions for the most advanced of engineering challenges. Furthermore, our team has developed comprehensive automation procedures that negate the need for repetitive calculations, allowing bespoke solutions to be realised in a relatively short space of time. This gives our clients the peace of mind that optimal results will be achieved whilst staying well within specified time and budget constraints.

Our highly qualified engineering team draws upon a wealth of experience to conduct advanced global analysis for our customers, adding significant value to projects and ensuring all regulatory frameworks are adhered to (DnV, API etc.).  We benefit from a multi-disciplinary pool of talented professionals who are able to approach each project in a different way to achieve real results. 

While we are confident in the scope of our global analysis work, we understand that in some cases, a fully integrated modelling approach is required. Therefore, where necessary, we seek to validate or strengthen our global analysis by drawing from our other core skill-sets. Some examples of recent cross-disciplinary analysis include:

 An integrated global and local analysis of subsea bend restrictors.

 An integrated global and local analysis of a free-hanging flexible hose.

 The development of a CFD model to determine drag amplification factors for flow around a monopile, which were then used in a full global analysis.
