This article is written specifically to address deployment of the Water Column Monitoring Equipment to Australia.
The WCM Equipment can be airfreighted to Australia via Antonov 124 or Ilyushin 76 airlifters. The equipment will require pre-mobilization checks at the storage facility in Houston, Texas and then transported via road to George Bush Intercontinental/Houston Airport (IAH) where at this point the equipment will be handed over to the Incident Owner and loaded into aircraft. The premobilisation checks, transport to IAH and loading of aircraft can typically take up to 72 hours. Fight time including technical stops is typically 49:30 hrs to Port Headland Western Australia as an example.
After unloading of the equipment at the destination it will require transport by road to the associated port where the deployment vessel will berth and take on the equipment. Mobilization of the WCM Equipment on a suitable vessel will require up to 48hrs to set up and conduct checks on deck before departure to incident location.
Vessel requirements for Water Column Monitoring Activities
Offshore WCM activities will require two vessels to be deployed:
- Primary vessel to undertake the WCM
- Runner vessel to transfer of samples and supplies between the WCM and shore.Water Column Monitoring Vessel

OSRL through a license agreement with Maritech Services Ltd allows Subsea Well Intervention Services (SWIS) subscribers to access to an offshore emergency response software platform (Sea/response). Sea/response provides subscribers with a real-time overview of vessels of opportunity specific to the requirements of the mission. A specific mission for WCM has been included in the software to provide input into response planning, exercises and actual events.
