|Damage Prevention Program|
The West African Gas Pipeline suffered a catastrophic loss of containment in early 2007 due, apparently, to damage by a ship's anchor. As a result of the incident, risk analysis was undertaken and effort expended on Public Awareness, Marine Risk Mitigation strategies and Marine Protection measures which culminated in the offshore Damage Prevention Programme (DPP).
Since April 2007, WAPCo and the WAGP Authority have been conducting Safety Awareness Publicity across the region to sensitize the maritime communities on the safety and security precautions for safe transmission. WAPCo's awareness campaign has been well established in the four main ports on the pipeline route. All Port and Naval officials are cognizant of the pipeline and the need to ensure it is protected from marine damage. The campaign is also a continuous process intended to cover all coastal communities especially the fisher folks along the pipeline rout. WAPCo has additionally trenched the two branches of pipeline in Togo and Benin under the sea bed that were recognized as vulnerable pipeline sections.
In conjunction with WAGP Authority Regulations, and as part of the risk mitigation measures a one nautical mile Exclusion Zone either side of the pipeline known as Pipeline Protection Zone (PPZ) has been adopted across the four countries to minimize the chances of causing damage to the pipeline. This zone and the pipeline are published in new editions of Admiralty charts especially Chart Number 1383 and 1384 which all mariners are encourage to consult when operating within the West Coast of Africa. Special marker buoys equipped with AIS transmitters and MMSI numbers are also installed at selected sections of the pipeline where shipping traffic is relatively heavy such as close to the ports of Takoradi, Tema, Lome, Cotonou and the Benin/Nigeria frontier.
Activities which constitute potential risk to offshore pipeline damage and which are strictly forbidden within the PPZ include but not limited to:
In line with our offshore pipeline safety requirements, WAGPA and WAPCo deem it important that the maritime community is made aware of the inherent dangers to human lives and property as well as the safety of the pipeline, should there be any violation of the identified safety precautions.

WAPCo and the WAGP Authority would appreciate public support in the dissemination of the above information to ensure safety of the public and a reliable gas supply system from producers in Nigeria to customers in Ghana, Togo and Benin.
