Subsea Pipeline Engineer (Installation & Construction)

ISS International SpA is seeking a highly skilled Subsea Pipeline Engineer (Construction & Installation) to support the offshore execution of a multiphase sealine.

As a Subsea Pipeline Installation Engineer the successful candidate will be responsible for overseeing the full construction and installation lifecycle of an offshore multiphase pipeline, including pipeline manufacturing, CRA cladding technologies, offshore pipelay operations, trenching, subsea tie ins, and detailed engineering reviews, ensuring seamless technical execution across vessels, fabrication yards, subsea structures, and all EPCI contractors involved.

Roles and Responsibilities

Pipeline Manufacturing & Metallurgy (CRA Focus)

• Oversee pipeline manufacturer conditions, ensuring adherence to project specifications for Corrosion Resistant Alloys (CRA).
• Verify manufacturing, inspection, and testing protocols for Mechanically Lined Pipe (MLP), Hot Roll Bonded (HRB) clad pipes, and Weld Overlay (WOL) components.
• Manage technical risks associated with thermal expansion mismatch and metallurgical bonding during the fabrication and reeling of CRA pipes.

Construction & Installation Oversight

• Monitor and supervise daily offshore pipelay operations (S-Lay, J-Lay) aboard contractor vessels for the multiphase line.
• Direct and approve welding methodologies specifically for subsea tie-in spools and risers connecting to the brownfield Sabratha platform.
• Review and consent to the EPCI Contractor’s Installation Manuals, Method Statements, and lay-ability analyses (e.g., tension settings, stinger configurations).
• Oversee critical offshore operations including shore approach pull-ins, A&R (Abandonment & Recovery), and subsea tie-ins (PLETs, PLEMs, ILTs).

Trenching & Seabed Intervention

• Evaluate and oversee the contractor's method to perform trenching between the two platforms across the subsea route at approximately 100m water depth.
• Verify the selection of seabed intervention equipment (plows, mechanical trenchers) based on geotechnical data and pipe protection requirements.

Detailed Engineering Review (Phase 2 Readiness)

• Review detailed pipeline structural and installation analysis (on-bottom stability, free span, buckle initiation) submitted by EPCM contractors.
• Interface & Contractor Management.
• Resolve technical queries (TQs) regarding offshore welding, NDT, and Field Joint Coating (FJC) applications for CRA and clad pipes.
• Ensure Company standards are not compromised by contractor schedule pressures during critical offshore tie-ins.

Qualifications, Experience, Knowledge and Skills

• Bachelor of Science Degree (BSc) in Mechanical, Marine, or Pipeline Engineering.
• Work experience of twelve (12) years in the Oil & Gas sector, with at least seven (7) years specifically dedicated to offshore pipeline installation and construction oversight .
• Proven field and manufacturing experience with CRA cladding technologies (MLP, HRB, WOL).
• Strong practical knowledge of deep-water trenching methodologies, tie-in spool fabrication, and riser installation.
• Demonstrated capability in detailed offshore pipeline analysis (software familiarity such as Abaqus, CAESAR II, or SESAM will be an advantage).
• Good command of English.
