The Marianas is docked at Walvis Bay undergoing inspections. The destination (Ghana) is incorrect. As for the gas case, gas is valuable, Namibia has to import it. The amount that is discovered will determine the value. If a commercial proven amount is found it could shelve the KUDU gas to power project for good as the Walvis basin is closer to land and higher population areas. The gas would be used for power generation which Namiba needs.
Hope this helps
