The floating production, storage and offloading (FPSO) vessel, Prof. John Evans Atta Mills, which will produce and store oil from Ghana’s Tweneboa-Enyenra-Ntomme (TEN) offshore oil fields, has sailed away from Singapore following it's conversion. The vessel departed the Tuas shipyard in Singapore on Saturday 23 January and her voyage to Ghana will see her sail westward across the Indian Ocean before rounding the southern tip of Africa and sailing up the West African coast.
