Under the contract that OSRL have with the Service Provider, there are a number of options available to OSRL to allow a fast and effective response.
During daylight hours dedicated OSRL aircrew are on standby at Doncaster Sheffield Airport, UK with a dedicated aircraft. OSRL will task the aircraft within 30 minutes (i.e. inform the Service Provider of the requirement to conduct an aerial surveillance flight). The mobilisation time for this service should be within 60 minutes (this mobilisation time includes the 30 minutes tasking time). If required, the Boeing 727 can be wheels up within 4 hours with Dasic Slickgone NS dispersant (UKCS only*) for a dispersant spraying flight during the day and can be mobilised during the night for spraying at first light.
*For any other mobilisation or for greater volumes of dispersant, response times will be as per the Participant/Associate Membership Agreement.
