Job Title: Senior Mechanical Engineer
Client: Global Supermajor (Oil And Gas)
Assignment Type: Residential - Contract
Start Date: ASAP
End Date: 31st July 2027
Location: Esbjerg, Denmark
Work Schedule: Monday - Friday - 8 Hours per day
Department: Engineering & Constructions (E&C)
Location to Perform the Work: Full Time Onshore
SCOPE OF WORK
The Senior Mechanical Engineer - Static position is responsible for:
Provides mechanical engineering support both within the Engineering & Construction
department, but supports also other departments (e.g. Business Development, CFR, Field
Operations) with experienced mechanical engineering assistance and guidance.
For modification projects on the existing installations, be responsible for the mechanical
engineering support to the project managers and follow the modification through all phases
from engineering until commissioning and startup.
Providing experienced mechanical engineering support during e.g. the detailed design
phases, requires a deep understanding of the mechanical systems on the existing platforms
to ensure the new modifications can be implemented safely and efficiently into the existing
systems. The mechanical engineer will review the detailed design package and assure the
quality of the mechanical engineering parts with focus on e.g. safety, layout & mechanical
handling, constructability, pipe stress and shutdown time & philosophy.
The work involves participation in design meetings with internal and external stakeholders,
participation in risk assessments e.g. HAZOP, 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 RFM's are initiated (Request for Modifications), be 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).
Manage conceptual studies and feasibilities studies, which typically involves the
management of external design contractor and liaising with several internal stakeholders.
The following includes a list of typical activities:
Define design basis/design premises
Piping and equipment layout and design
Stress calculations of piping systems and equipment e.g. nozzle loads, PSV/BDV
relief load calculations
Transient analysis of mechanical systems e.g. vibrations, thermal changes, or stress
during dynamic events
Incident investigation of corrosion, vibration and fatigue issues e.g. small bore
branches
Fitness For Service (FFS) assessments e.g. in accordance with API 579
Compliance with relevant ANSI/ASME, EN, ISO and manufacturer's standards
Preparation of mechanical data sheets e.g. valves, pressure vessels, tanks, pumps,
special piping parts etc.
Detailed design review and input to other disciplines
Piping Isometrics, Pipe Supports and Equipment layout drawings
Discussions with vendors (e.g. piping, control valves, pressure vessels, pumps)
Technical involvement in the procurement process as Technical Approver
Prepare Derogation Requests
Input to FSS
Participation in and close out of actions:
o Design Review
o HAZOP
o HAZID
o Start-up review
o Follow up and close-out of HSE Synergi cases
o Prepare Investigation & Incident Reports e.g. HSE Return of Experience
