Risks and contingency

Several potential risks have been identified:

  • Unstable hole conditions.
  • The presence of chert and/or turbidites that can impact core recovery.
  • Weather: although the expedition is scheduled to take place in the winter to avoid cyclone season, severe weather may still occur.
  • Sediments with high gas concentrations are expected to be recovered. This can lead to core expansion on deck. The cores may require degassing on the catwalk.

All of these factors may impact drilling and coring operations.
