IOTA Group is looking for an experienced FPSO Topsides Structure and Weight Control Engineer to join the teams of a leading international energy company and contribute to a major ultra-deepwater FPSO development.

Designed to operate at approximately 3,000 metres water depth, the FPSO will have a production capacity of around 160,000 barrels of oil per day and will be connected to up to 40 subsea wells.

The position will initially be based in Paris, followed by potential assignments in Singapore and Geoje, South Korea, throughout the different phases of the EPSCC project.

As FPSO Topsides Structure and Weight Control Engineer, you will be responsible for ensuring the structural integrity and weight compliance of the FPSO topside modules throughout the EPSCC phases.

Working closely with the Topsides Structural Lead, contractors, vendors and multidisciplinary engineering teams, your main responsibilities will include:

• Monitor and validate structural design and weight control activities performed by contractors and vendors.
• Ensure the evolution of topside weight and centre of gravity remains within the applicable marine and structural constraints.
• Review contractor deliverables, including structural drawings, calculation notes, finite element analyses and lifting or marine operation reports.
• Track and validate weight data and centre of gravity evolution using dedicated weight control tools and registers.
• Support the Topsides Structural Lead in managing technical interfaces and ensuring compliance with project specifications.
• Participate in multidisciplinary design reviews, including 3D model reviews, HAZID and HAZOP sessions.
• Coordinate with process, layout, piping, marine and other engineering disciplines.
• Interface with contractors and subcontractors to ensure constructability and compliance with structural and weight requirements.
• Support the management of deviations, design changes and anomaly reports related to topside structures and weight control.
