Aerial Dispersant Spray (ADS) Service

Information relating to the procurement of the Aerial Dispersant Spray service including background information, upcoming events and links to resources.

Background 

As an Executive Agency of the Department for Transport (DfT), the Maritime and Coastguard Agency (MCA) supports the Department in developing and implementing the Government’s maritime safety and environmental protection strategy by:  

  • Setting standards and regulation  

  • Checking the standards of ships and seafarers  

  • Providing services to seafarers  

  • Monitoring our coasts and seas and responding to emergencies.  

We have two broad objectives:  

  • Safety: Through accident prevention and effective search and rescue coordination and response, improve the safety of ships and people at sea and at the coast  

  • Environment: Through our monitoring of ships and response to pollution incidents, protect the marine environment  

Our vision is to be a world-class organisation that is committed to preventing loss of life, continuously improving maritime safety, and protecting the marine environment. 

“Safer Lives, Safer Ships, Cleaner Seas”  

Aerial Dispersant Spray Service 

The MCA has a statutory responsibility to respond to marine oil spills throughout the UK’s Exclusive Economic Zone (EEZ). The EEZ extends to 200 nautical miles from the coastline or to the nearest median line with neighbouring coastal states. This equates to c. 17,000 km of coastline and c. 773,000 km2 of sea area. The MCA is also bound by an international agreement to assist neighbouring states which have requested support in responding to oil spills.  

The MCA has a number of contracts for services to support our objectives, including a contract for Aerial Dispersant Spray Services which can respond to oil spills. This service provides aircraft which are capable of carrying and rapidly applying large quantities of chemical dispersant to an oil slick. The chemical dispersants act to break up oil slicks and accelerate the process of biodegradation (the consumption of oil by microorganisms). Aerial Dispersant Spray is most suited to large oil spills in deeper water away from shore.

Current service 

The current Aerial Dispersant Spray Service consists of:

Model services contract

The Model Services Contract will be used as a basis for the contract for the Aerial Dispersant Spray Service. However, this is not the proposed contract but rather a starting point from which the MCA’s drafting will begin.  The base document will be amended and changed to match MCA’s requirements. Areas will be added, varied and deleted as required.
