Marine and Subsea

As an extension to our activities within Oil & Gas, we have experience and capabilities to meet unique challenges within marine and subsea applications, such as wave loading, trenching and reliability assessment.

Software and Consulting

We have worked on a large number of sea-based materials handling projects, involving significant structural stress and fatigue analysis. Typically, structures are fabricated assemblies so we have to pay special attention to welded and bolted connections, including mounting systems to FPSOs & other vessels and wave-derived loading conditions. We are familiar with the requirements of API 16F for marine drilling riser equipment.

We have helped some of our consulting clients develop their own in-house FEA capabilities through the supply of Ansys software, training and on-going technical support.

Likewise, our fluid dynamics team has undertaken a range of valve, subsea stab connector and ship-based fluid transport simulations considering both flow and thermal issues. We have also supported umbilical connector clients who use Ansys electromagnetic capabilities to study electrostatic and eddy current effects.

Considering the large capital costs of subsea equipment together with the challenge of maintenance, our ReliaSoft tools help clients apply reliability techniques in accordance to practices recommended by API RP 17N. We provide gap analysis and full consulting services to help equipment manufacturers and operators plan and manage their technical risk strategies.

For operations involving the movement of sea-bed sand and soil, such as trenching or development of foundations, we support subsea companies to undertake stability and settlement analysis using leading geotechnical software. PLAXIS offers several material options for undrained soil behavior encountered offshore, such as the NGI-ADP and soft-soil creep models.


We have worked with a large number of  companies involved in marine and subsea applications, including:

Balltec | Babcock Marine & Technology | BG Energy | Halliburton | Moffat 2000 | OneSubsea
Parkburn Precision Handling Systems | Rolls-Royce Marine | RSA | Siemens Subsea (Tronic)
Soil Machine Dynamics | Transvac Systems | Trelleborg | UTEC Geomarine

Fast response and very knowledgeable staff, an excellent all-round service.

London Marine Consultants

Fantastic support - I have contacted a few times and have always had the problem solved. Professional, friendly and reliable service! The engineer I dealt with has been of great help!

Monition Ltd

Wilde’s integrated scope of material testing, material modelling and model validation provides an excellent base for our FE analysis, allowing our in-house analysis team to focus on providing high-quality analysis of our products.

Siemens Subsea

We are very satisfied with the CFD consultancy project that Wilde completed for us, and found our contact with them very rewarding. The project deadline was extremely tight so we especially appreciated Wilde’s quick response, and the fact they completed the work to a very high standard even sooner than requested. Having an independent third party such as Wilde to validate our data provided important reassurance for our client.

Dunlop Oil & Marine

Very good course. Communicates a huge complex package simply and effectively……A rounded course covering a range of topics, presented by a very knowledgeable tutor.

Technip Umbilical Systems

Excellent training (1 – 1 training)

Soil Machine Dynamics Ltd (SMD)

On completion of the design, Wilde, being a preferred partner of Parkburn, was enlisted to carry out independent verification. After specifying the design requirements and objectives of the analysis, Parkburn can rely on Wilde to provide reliable results in a presentable format ready for review by design approval agencies.

Parkburn Precision Handling Systems

Wilde have given a first-rate service enabling us to prove and improve critical design features.

Moffat 2000

Wilde quickly understood the analysis that needed to be done on the Forward Tooling Assembly and used their FEA and CFD expertise to develop a new design to optimise the efficiency of the new vehicle within the required time scales.

Forum Energy Technologies

An engaging and interesting course… A most useful course which covered everything we needed at this stage. I’d hope to take some more advanced training in the future with this tutor.

Soil Machine Dynamics Ltd (SMD)

An excellent course which has given me plenty of extra tools to ensure success in complicated models

Siemens Subsea (Tronic)

The training I received was professional and practical and provided by a competent and knowledgeable engineer. A very good course and a great introduction to ANSYS


Excellent training provider in ANSYS CFD modelling with in-depth experience and expertise.

Rolls-Royce Marine

The course enabled me to get a good grasp of the of the key functions to ANSYS Workbench which I found intuitive and with a user friendly interface. The material was well presented and the tutorials reinforced learning ….tutor has a huge amount of knowledge of ANSYS. Very Professional.

Babcock Marine & Technology

ANSYS enables us to calculate stresses and FEA limits to optimise our design solutions and provide confidence in our products. By using this software, we have not only saved costs and time within our projects but also improved the reliability of our products.
