Proposal & quotation phase

• Analyse customer enquiries, specifications, and tender documents, often issued under high-spec Oil & Gas / Offshore standards, and translate them into technically robust proposal concepts.
• Prepare detailed technical and commercial quotations, including system configurations, scope definitions, assumptions, and exclusions.
• Develop accurate and transparent cost and price calculations, covering equipment, engineering, manufacturing, logistics, commissioning, FAT, and risk contingencies.
• Coordinate inputs from Engineering, Procurement, Service, and Projects to ensure proposals are complete, compliant, and executable.
• Ensure compliance with stringent customer requirements, class rules, and industry standards.
• Identify technical, commercial, and execution risks early in the proposal phase and ensure these are clearly documented and correctly priced.
• Support Sales during clarification rounds and technical negotiations with customers.
