Advanced Offshore Installation Analysis.

High-fidelity analysis of dynamic cable, riser and umbilical installation campaigns. We assess tensions, curvatures, seabed interaction and operability to de-risk installation, support planning decisions and enable safe offshore execution.

• Dynamic installation and pipelay analysis
• Tension, curvature and fatigue assessment
• Touchdown and seabed interaction modelling
• Installation method and equipment selection
• Vessel operability and weather sensitivity

We plan, simulate and verify complex offshore heavy-lift operations, integrating vessel motions, crane behaviour and operational constraints. Our analysis supports safe execution, realistic lift windows and optimised installation methodologies for challenging offshore environments.

• Offshore, subsea and ship to ship crane lift analysis
• Load-out analysis
• Seastate RAOs, sheltered effects and advanced hydrodynamic modelling.
• Rigging, slings and lift geometry verification
• Installation methodology optimisation

We assess the feasibility, safety, and weather limits for floatover operations, covering standby, mating, and exit phases. Using high-fidelity numerical simulations, we evaluate vessel motions, relative movements, mooring tensions, and impact loads to ensure safe topside installation and optimised offshore execution.

• Standby, mating, and exit phase assessment
• Vessel motion and relative movement evaluation
• Impact loads on LMUs/DSUs
• Mooring design and tension analysis
• Weather window and operational limit verification

Technical assessment of floating and subsea hookup operations to optimise method and operability. Our work focuses on method optimisation to realistically utilise assets and the development of valid operational limits to reduce offshore risk and cost.

• Floating hookup analysis
• Subsea tie-in analysis
• Installation methodology and asset validation and optimisation
• Sequencing optimisation based on asset and environment
• Collaboration with project engineers for offshore execution planning

Assessment of vessel operability, weather exposure and schedule risk for offshore installation campaigns. We quantify operational windows and downtime drivers to support realistic planning, risk mitigation and improved offshore efficiency.

• Asset selection – vessel motion and operability analysis
• Weather window and downtime assessment
• Metocean sensitivity studies
• Schedule and risk optimisation
• Offshore contingency planning

Advanced analysis of coupled systems, multi-vessel operations and non-standard installation scenarios. We integrate hydrodynamics, statistical tools, structural response and operational constraints to de-risk complex offshore campaigns.

• Coupled and interacting system analysis
• Multi-vessel installation scenarios
• Novel or non-standard installation methods
• FEED and detailed engineering support
