Seminars

Thursday 21st January 2027
Panel: Assembling the First Fleet: The Whole Supply Chain, in One Room, Live
8:30 am
  • Every link in the chain, owner, EPC, MEP, engineer, fabricator and QA, in one room naming their single biggest blocker
  • Stress-testing a real delivery sequence live, exposing where the first fleet actually breaks down
  • Agreeing on stage what each link needs from the others, the alignment you cannot get in any single-company meeting

Practical Takeaway: Leave with something you can get nowhere else: a live, room-tested view of where the whole delivery chain breaks first, who owns each fix, and exactly what every link needs from the others to commit to a real schedule.
