Whether during detailed design, independent verification or pre-contract award studies the main engineering design activities required are:

• Development of the Design Basis
• Global configuration design
• Design for strength
• Fatigue assessment
• Corrosion fatigue
• Interference analysis and clashing assessment
• Auxiliary equipment design
• On-bottom stability for route turns at base of catenary
• Model set-up
• PLET/PLEM design
