Job summary

Aventa is seeking an Installation Analysis Engineer to lead the numerical modelling of shallow water cable installations. You will build and run OrcaFlex-based models, derive load cases, and determine operational parameters for tension and touchdown windows.

You will develop and document analysis methodologies, prepare client-ready reports for Marine Warranty Surveyor review, and collaborate with installation engineers to translate results into actionable procedures. Paris office preferred.

Qualifications

3-8 years of offshore or subsea installation analysis experience.
Hands-on OrcaFlex modelling ability; independent setup of cable installation models.
Strong knowledge of cable and offshore structural mechanics.
Experience producing analysis reports for MWS review.
Nice-to-have shallow water installation analysis experience.
Familiarity with Python/MATLAB for automation.
Experience with DNV Sesam or ANSYS Mechanical is a plus.
French and/or German language capability beneficial.

Responsibilities

Build, run, and interpret OrcaFlex (or equivalent) models for shallow water cable lay operations: static catenary configurations, dynamic load cases, bottom tension, touch-down point behaviour, lateral buckling tendency, seabed friction interaction
Develop the load case matrix for each installation campaign: define the governing environmental conditions, operational headings, cable pay-out rates, and vessel motion inputs required to bound the installation design envelope
Derive and document operational parameters: maximum allowable tensions, minimum bend radius (MBR) verification under static and dynamic conditions, touch-down monitoring setpoints, weather operational limits
Conduct cable pull-in analysis for beach approaches and HDD exits: tension in the cable during pull, sag‑bend behaviour, seabed contact forces, cable protection requirements at the pull‑in point
Perform cable abandonment and recovery analysis: catenary and tension behaviour during hold and re‑lay operations, weather window derivation for abandonment events
Carry out parametric sensitivity studies to bound the effect of environmental and operational uncertainties on key installation parameters
Produce installation analysis reports to a standard suitable for client delivery and Marine Warranty Surveyor (MWS) review: clearly documented assumptions, methodology, load cases, results, and operational limits
Prepare engineering calculation notes and technical memoranda supporting installation procedure development
Support the Lead/Senior Installation Engineers in the preparation of MWS technical submissions: provide the numerical substantiation behind operational parameters
Maintain and version‑control analysis models throughout the project lifecycle — from early‑phase feasibility to final pre-campaign approval
Work closely with the Installation Engineers to translate analysis outputs into practical operational parameters and installation procedures
Participate in installation engineering reviews (HAZID, HAZOP, design reviews) to ground analysis outputs in operational reality
Develop and maintain internal analysis templates and model libraries to improve consistency and efficiency across projects
Contribute to lessons‑learned processes: compare pre‑campaign analysis predictions against as‑installed monitoring data and identify model improvement areas
