Industry: Offshore

Structural analysis for offshore structures and equipment.

Independent analysis of structures, installation systems and modifications under environmental, operational and accidental loading.

Offshore decisions combine structural analysis with the actual configuration, operating history and condition of the structure.

From installation equipment to continued operation.

AeroMech can support jackets, jack-ups, lifting tools, monopile handling systems, vessel modifications, cable handling equipment, boat impact and lifetime extension.

The work can be a new analysis, an independent review of an existing model or a second opinion on the governing structural issue.

Relevant systems

Examples of offshore structural questions.

The images illustrate equipment types for which global behaviour, local strength and operational load paths can all matter.

Typical engineering questions

Questions AeroMech can help answer.

Is the natural frequency of the structure outside the wave-excitation frequency range?
What are the structural consequences of construction in an earthquake area?
Is vortex-induced vibration an issue?
How can compliance with the applicable standards be checked quickly?

Finite element assessment of a ship or barge cross-section, illustrating global and local structural behaviour.
Lifetime extension

Use operating history and inspection evidence.

A lifetime-extension assessment combines the original design basis with actual loading, modifications, corrosion, inspections and updated analysis.

AeroMech can also draw on aerospace experience in fatigue and damage tolerance. Crack-growth thinking, residual strength and inspection planning provide useful principles, while offshore-specific wave loading, corrosion and access limitations remain part of the assessment.
