Damage Prevention Program


The West African Gas Pipeline suffered two main line breaches offshore since its inception, first offshore Cotonou in 2007 due, apparently, to damage by a ship's anchor. The second breach took place offshore Lome in 2012. This was also caused by the Tanker MT ENERGY CENTURION which was boarded and hijacked by a gang of criminals at the Lome anchorage and forced to sail into deeper waters without allowing the vessel to weigh anchor. In the process the vessel drag her anchor across the pipeline severing it into two. It took WAPCo about eight months to return the line into full operation.

Since the lunch of the Damage Prevention Programme (DPP) after the first incident in 2007, WAPCo in conjunction with the West African Gas Pipeline Authority (WAGPA) has been analyzing and reviewing the risk of damage to the pipeline from time to time with the view to improving the risk mitigation measures needed to prevent any future damage to the line. WAPCo, with the support of WAGPA 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 also 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 which serves to remind inhabitants of the coastal communities especially fisher folks of the need to avoid practices that may be inimical the pipeline. There is currently the WAGP Standing Safety Committee, whose membership comprises representatives of WAPCo, WAGPA, the Navies, Maritime Authorities, Ports and Harbours Authorities and the Marine Police of the WAGP States. It meets at least once a year to review threats to the safety of the pipeline and cause to implement policies that leads to overall safety and security at sea in general and the WAGP in particular.

WAPCo has additionally trenched the two branches of pipeline into 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 Admiralty charts especially Chart Number 1383 and 1384 which all mariners are encouraged to consult when operating within the West Coast of Africa. Special marker buoys equipped with AIS transmitters and MMSI numbers that were 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 are being replaced by virtual buoys. The physical buoys have suffered irreparable damage due to wrong usage by seafarers and hence the need for their replacement.

Activities which constitute potential risk to offshore pipeline damage and which are strictly forbidden within the PPZ include but not limited to:

  • Anchoring
  • Bottom Trawling 
  • Ship Anchor Drag and trawl board impact.
  • Illegal Fishing Methods such as use of dynamite
  • Construction
  • Mining including sand winning
  • Any activity that risk the chance of making physical contact with the sea bed within the zone and involves a risk of damaging the pipeline.
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.
Mariners are particularly advised not to anchor or trawl within the PPZ as gas from a damaged pipeline could cause an explosion, loss of vessel buoyancy or other serious hazards. It must also be noted that the main pipeline is not buried and it may reduce charted depths by up to 2 meters especially at the Tees where the valves are encaged.

The pipeline has also spanned seabed undulations and may cause fishing gear to become irrecoverably snagged putting a vessel in severe danger. Mariners are further encouraged to report any unusual observations to the various Maritime Authorities, Ports and Harbours Authorities, or Navies of the 4 affected countries.
