Purpose As Senior Marine Engineer, you deliver safe, robust and operable marine and utility system designs for offshore floating facilities such as FPSOs and FSOs. The role provides technical ownership of assigned marine systems throughout the project lifecycle, from proposal and FEED through EPC, yard execution, commissioning and operations support, ensuring compliance with classification, regulatory, client and SBM requirements. Responsibilities You act as system engineer or system owner for defined marine and utility systems on FPSO projects across proposal, FEED, EPC and brownfield phases – including direct interface with shipyard. You develop marine system designs including PFDs, P&IDs, UFDs, system descriptions and engineering philosophies. You perform system sizing, utility demand calculations and equipment selection for marine and auxiliary systems. You prepare and review technical requisitions, datasheets and vendor documentation for marine packages. You act as package engineer for assigned marine systems, supporting procurement, fabrication, FAT, SAT and yard activities. You interface closely with Naval Architecture, Hull, Piping, Mechanical, HVAC, Electrical, ICSS and Process disciplines to ensure integrated and operable designs.
