This Subsea emergency preparedness slide deck is an initial operator aid for when reviewing emergency response plans for a specific subsea portfolio.
It is not intended to provide major incident response guidance but does illustrate the industry’s present capacity to provide a rapid response to these scenarios. It also does not provide guidance on pre-planning for an intervention support structure as it was not considered possible to design a ‘one size fits all’ structure and there is insufficient commonality to justify developing guidance.
The document covers seven scenarios that have been assessed for possibility not for probability. Each sub scenario has extremely low probability. The more complex interventions could have a response time comparable to drilling a relief well.
