  Heerema Reel Transport Challenge: Simulation to Deal with Increased Complexity

  • Noortje Sturm, presenter, Heerema Marine Contractors, Netherland

  HMC is investing in a new vessejl the Aegir for installing complex deep water infrastructure and pipeline projects (completed mid 2013). This will be the first reel-lay vessel for HMC. Reel-lay is a method for installing rigid subsea pipelines. Long pipe segments are welded onshore and then spooled onto a large vertical pipe reel in one length. Where competitors have their reel fixed on the vessel, HMC decided to implement a concept of shuttling reels between the installation vessel and the pipe production yard. The Aegir stays in the field and can install pipelines continuously, while competing vessels have to sail to the yard to refill the reel in critical project time. The aim is to be more competitive. By shuttling reels the project logistics become more complex, because an extra non-critical product flow is introduced. This puts an effort in making the reel supply cost-efficient and robust. Robust as different risks/uncertainties can influence the result: weather downtime, breakdown and/or rework. The risks vary per project: different materials, region, etc. By using simulation the aim is to search for both a cost-efficient as a robust concept with respect to potential risks/uncertainties. Scenario simulation and sensitivity analysis support to understand the robustness and boundaries in order to reduce the choice options. Now HMC is at a point on where simulation could support in project preparations, in which multiple departments are involved. User friendliness and presentation of the results becomes more and more important. This is a challenge we would like to discuss.

  Deploying a Risk-Based Planning and Scheduling (RPS) Solution for Lockheed Martin Aeronautics

  • Steve Pare, presenter, Simaco
  • Dennis Pegden, Simio LLC

  Despite recent media reports, the production rate of the F-35 Lightning II aircraft is increasing. Over a period of 4 years, the yearly number of aircraft produced will have increased 6 fold. In order to plan its production activities and better control its costs, Lockheed Martin is deploying a Risk Based Planning and Scheduling solution. This presentation will provide insight into the complexity of producing a modern day fighter, its planning challenges, the production system's vulnerability to randomness and the need for a risk focused planning environment. This will be followed by a description of the new system's Simio based architecture, the system's deployment history and finally its benefits.
