Leap29 is supporting a large-scale energy project in Italy. The work relates to a major gas development that includes offshore wells, subsea infrastructure, and upgrades to an onshore processing facility supporting long-term gas export operations. The scope covers new field development phases, flowlines, tie-ins, and reliability improvements across both offshore and onshore assets.

The Subsea Structure Engineer is responsible for engineering design, verification, installation support, and integrity assurance of subsea structures for shallow-water offshore developments. Typical structures include manifolds, PLETs, PLEMs, jumpers, tie-in frames, pipeline supports, and foundations.

Engineering Design and Analysis
• Perform structural strength, global and local analysis, and fatigue assessments.
• Evaluate hydrodynamic loading and soil–structure interaction.
• Review FE models using ANSYS, Abaqus, SACS, and OrcaFlex.
• Ensure all work complies with DNV, API 17D, API RP 2A, and ISO 13628 requirements.

Structural Layout and Deliverables
• Develop GA drawings, structural layouts, foundations, and mudmats.
• Review protection measures such as mattresses and rock placement.
• Prepare interface drawings for pipeline, controls, and umbilical systems.

Installation Engineering Support
• Provide input for lifting design, rigging, and handling operations.
• Review procedures for lowering, positioning, and tie-in activities.
• Support offshore campaigns covering load-out, transport, and installation.

Interface and Coordination
• Work closely with pipeline, controls, umbilical, and geotechnical teams.
• Support fabrication yard activities including welding, NDT, and coatings.
• Participate in HAZID, HAZOP, constructability reviews, and model reviews.

Material and Fabrication Support
• Review welding procedures, NDT plans, coatings, and fabrication tolerances.
• Support FAT and SIT for structural components.

Integrity and Operational Support
• Contribute to in-service integrity assessments.
• Review ROV and diver inspection reports and as-built documentation.
• Update structural models for life-of-field evaluations.

Required Qualifications
• Bachelor’s degree in Mechanical, Civil or Structural Engineering, or Naval Architecture.
• Master’s degree in Offshore, Structural, or Ocean Engineering (preferred).
• Five to twelve years of subsea or offshore structural engineering experience.
• Proficiency with ANSYS, Abaqus, SACS, or OrcaFlex.
• Strong knowledge of API, DNV, and ISO standards.
• Offshore experience in installation, inspection, or FAT/SIT activities (preferred).
• Strong communication and problem-solving skills with effective interface capability.
