Comment

Clive Carver, Chairman said

"That a major international oil company considers chartering the Caspian Explorer to be the most technically and commercially advantageous option for the development of their field in the Caspian Sea reinforces the board's view that the Caspian Explorer will be a major contributor to the Group."
