On May 19, 2006, the Azerbaijani and Turkish Navy held a joint military exercise on safeguarding the security of oil and gas pipelines in Baku. The training session was observed by Azerbaijan Navy commander Shahin Sultanov and Turkish Armed Forces attaché Seyhan Ceyhan. The activities aimed to ensure the safety of the Baku-Tbilisi-Ceyhan pipeline (BTC), the main export pipeline to take Caspian oil to Turkey and further on to world markets, as well as on expanding cooperation between the two countries’ military forces. The exercises started with the clearance of mines on the seabed. This was followed by rendering harmless the traps planted in the area by symbolic terrorists. The training concluded with the practice of maritime and air operations.
