Average Most Probable Discharge (AMPD) Coverage Services
From Vessels Services
Situation No. 2: Cargo Operations Away From an MTR Facility (i.e. STS Lightering):
Dependent upon the transfer location you may be required to contract for Oil Spill Removal Organization (OSRO) AMPD resources to insure their availability as required under your Vessel Response Plan (VRP).
- For nearshore locations (< 12nm from shore), special OSRO arrangements will be needed for AMPD coverage.
- For major offshore lightering zones (and >12 nm offshore) special arrangements for AMPD coverage are normally not required as both OSROs (Marine Spill Response Corporation and National Response Corporation) have positioned resources to meet AMPD requirements.
- However, we strongly recommended that you advise your OSRO at least 24-hours in advance of all intended operations for STS lightering of cargo (location, date, and time). Your OSRO will, in turn, advise if contracting arrangements are needed to ensure availability of AMPD resources.
