ASI Groups Scott Black will present at the 2019 Cutting Edge Conference

Scott Black is Vice President at ASI Marine. He has over 35 years of experience in the marine industry and 10 years in the tunneling industry. Scott is presenting alongside Steve Skelhorn at the Cutting Edge ConferenceTuesday, November 19 at 11:30 am. Scott will be presenting “Hyperbaric Interventions – Preventative or Reactive.” Read the full abstract below:

On all tunnel projects, much effort is focused on how to access the cutter head of the tunnel boring machine (TBM) for repairs and maintenance. Common industry acumen is as follows (and in the following order):

  1. Free air entry is better than hyperbarics. (Hyperbarics are a last resort)
  2. Specify / provide one or more safe havens along the tunnel drive
  3. Specify / provide equipment to facilitate the easy entry into the cutter head
  4. Specify / provide hyperbaric equipment on the TBM
  5. Design equipment to allow speedier repairs
  6. Draft highly prescriptive specifications to ensure the work will be carried out to the highest standard

This presentation looks at this conventional wisdom and concludes that perhaps it isn’t so wise after all.

We want to challenge the above with the following statements:

  1. Hyperbarics is not a “Tow Truck”
  2. Safe Haven are rarely havens
  3. Equipment to facilitate head entry often leads to the need for head entry
  4. Hyperbaric equipment is highly specialised and sophisticated and is then mounted to a TBM
  5. Focus design on durability, not replaceability
  6. Best design + best equipment + lowest bidder = highest cost?
