Research & computing

Bringing offshore reality into the model.

Physical insight, numerical methods and purpose-built tools. Developed around the questions our engineers meet in practice.

Analysis with perspective

The sea sets
the questions.

An offshore system is never just a model. Its response depends on the environment, the connections, the installation sequence and the way it will be operated.

Our engineers bring those realities into the study from the outset. We connect hydrodynamic theory, numerical methods and practical offshore experience to decide what needs to be represented—and how much detail the question deserves.

Available measurements, model tests and engineering observations provide reference points. Clear assumptions and considered interpretation make the results useful to the people designing and delivering the work.

Connected methods

From a physical question
to an engineering decision.

Methods are selected around the behaviour to understand, the available evidence and the decisions ahead.

01

Represent the system

Connect geometry, environmental conditions, interfaces and operating assumptions. Identify where a simplified representation is useful and where more detail matters.

02

Examine the response

Use diffraction, coupled dynamic analysis or CFD as the question requires. Review numerical sensitivity and interpret the result alongside available physical evidence.

03

Compute with purpose

Our computing resources in France support demanding engineering studies and research. Through our sister brand Dynamics Computing, our infrastructure includes 2,048 CPUs.

Research in practice

Knowledge that grows
with the work.

Vessel knowledge

Nautilus Global Tanker Database

A research resource combining information on more than 30,000 tankers with hydrodynamic models for marine engineering studies.

It supports questions around mooring, berthing, CALM buoy design and risk assessment, bringing vessel information and response modelling into the same starting point.

A consistent basis for comparison

Floating wind benchmark

An ongoing comparison of floating wind concepts for turbine sizes from 5 to 20 MW.

A consistent hydrodynamic approach, load-case matrix and toolset help distinguish the behaviour of each concept. The aim is to inform technology selection on a comparable engineering basis.

Tools built
around the work.

Focused tools that help our engineers prepare cases, organise results and look more closely at system behaviour.

Free-span postprocessor

Identifies and classifies unsupported spans along laying routes for cables, pipes and umbilicals, bringing route geometry into the engineering review.

A multidisciplinary toolset.

Tool selection follows the scope and the questions the analysis needs to answer.

A habit of asking why

Knowledge grows
through exchange.

Reference material, engineering judgement and an open conversation all have a place beside the model. Our core team and specialist network connect research questions with the practical demands of offshore work.
