Senior Mechanical Engineer - Static

Assignment Type: Residential - Contract

Start Date: 1st August 2026

End Date: 31st July 2027

Location: Esbjerg, Denmark

Work Schedule: Monday - Friday - 8 Hours per day

Department: Engineering & Constructions (Eamp;C)

Location to Perform the Work: Full Time Onshore

Scope of Work

The Senior Mechanical Engineer - Static provides high-level mechanical engineering support within the Engineering amp; Construction department and supports other departments (such as Business Development, CFR, Field Operations) with experienced mechanical engineering assistance and guidance.

For modification projects on the existing installations, this role is responsible for mechanical engineering support to project managers and for following modifications through all phases from engineering until commissioning and startup.

The role involves providing experienced mechanical engineering support during detailed design phases, requiring a deep understanding of the mechanical systems on the existing platforms to ensure new modifications can be implemented safely and efficiently into existing systems.

The Senior Mechanical Engineer will review detailed design packages and assure the quality of the mechanical engineering elements with a strong focus on safety, layout and mechanical handling, constructability, pipe stress, and shutdown time and philosophy.

The work involves participation in design meetings with internal and external stakeholders, participation in risk assessments such as HAZOP and HAZID, participation in Factory Acceptance Testing (FAT), and potentially providing onshore or offshore support during construction, mechanical completion, commissioning, and start-up of facilities.

When new Requests for Modifications (RFMs) are initiated, this role is responsible for maturing the original suggestion into a conceptual solution, which involves a technical description of the recommended solution including initial estimates on budget and timeline (Statement of Requirements).

The Senior Mechanical Engineer will manage conceptual studies and feasibility studies, which typically involves management of external design contractors and liaising with several internal stakeholders.

Key Responsibilities

The following includes a list of typical activities:

• Define design basis and design premises
• Piping and equipment layout and design
• Stress calculations of piping systems and equipment, including nozzle loads and PSV/BDV relief load calculations
• Transient analysis of mechanical systems, such as vibrations, thermal changes, or stress during dynamic events
• Incident investigation of corrosion, vibration, and fatigue issues (for example, small bore branches)
• Fitness For Service (FFS) assessments, for example in accordance with API 579
• Ensure compliance with relevant ANSI/ASME, EN, ISO and manufacturer's standards
• Preparation of mechanical data sheets for valves, pressure vessels, tanks, pumps, special piping parts, and similar equipment
• Detailed design review and input to other disciplines
• Development and review of piping isometrics, pipe supports, and equipment layout drawings
• Discussions with vendors (for example, piping, control valves, pressure vessels, pumps)
• Technical involvement in the procurement process as Technical Approver
• Prepare Derogation Requests
• Provide input to FSS
• Participation in and close-out of actions related to:
  • Design Review
  • HAZOP
  • HAZID
  • Start-up review
  • Follow-up and close-out of HSE Synergi cases
  • Preparation of Investigation and Incident Reports, such as HSE Return of Experience (REX)

• Mechanical Completion, Commissioning, PIMS
• Participate in tests, such as FAT/SAT
• Offshore testing
• EPC contract preparation and review
• Project management
• Interface coordination with other disciplines and various stakeholders involved in the project
• Third party verification and close-out of comments
