Perdido GOM Platform Safety System Design

During the Front End Engineering & Design (FEED) phase the assumptions and conclusions of the pre-FEED were checked and updated. The basis for the FEED was the Basic Engineering Design Data with system sizing and documentation developed sufficient for Yokogawa to produce an detailed proposal to the EPC.
The basis for the FEED was the Basic Engineering Design Data and met the following objectives:
▪ Review the scope of work, basis of design and other design input data to determine if there are changes in the assumptions and conclusions.
▪ Provide a system design with sufficient detail to move to the EPC phase of the project.
▪ Development of the project design specifications and technical details in accordance with the engineering requirements, standards and specifications.
▪ Support the project team in completion of the required phase gate review and deliverables to enable project sanction.
▪ Support the procurement process through RFQ preparation to determine industry market costs and schedules for equipment for Long Lead Items.
▪ Perform capital cost estimates for the project, adequate to meet project sanction requirements.
▪ Contribute to the Project Execution Plans for the implementation phase of the project, including an organization chart showing resources, engineering description, procurement, fabrication, installation, commissioning and hand-over activities.
▪ Contribute to the Master Project Schedule.
▪ Preparation of documents needed for the implementation phase of work; requirements for the design, fabrication, installation, commissioning and start-up of the facility.
