Perseus 1B Rig Mob Main ChallengesPerseus 1B Rig Mob Main Challenges• New crews, access to crews• Access to engineering support• Reinstating rig contractor• Project implementation management• Productivity early on• Procurement turnaround• Brownfield “growth”• Critical path in derrick• Platform requirements:

– Hot work– Concurrent activity– Inductions– Travel booking system

SuccessesSuccesses

• HSE and Teamwork Offshore• Early start strategy• Focus on critical path• Engaging workforce in critical path• Worked estimate in detail at the outset• Engaging stakeholders

Project Project LearningsLearnings

• Cost Engineers more versatile and project focussed than accountants

• Planners spend considerable time manipulating Primavera and need to be focussed on critical path

• Need to understand estimating jargon: “Norms, Productivity, Non-prods, Growth, Contingency, Probabilistic”

• Project quality processes need to be focussed on project objectives

• Project Execution Plan: Very good document• Toll-gate reviews have to be managed carefully
