A vessel with a storage capacity of two million barrels of oil has exploded off the coast of southern Nigeria’s Delta state, raising fears of an environmental disaster and concerns about the fate of its crew. Al Jazeera quotes the Shebah Exploration & Production Company Ltd as saying that flames had engulfed the Trinity Spirit, a floating production, storage and offloading vessel can process up to 22,000 barrels of oil a day, following a blast a day earlier. Images published by local media showed thick black smoke billowing from a sinking ship engulfed by flames.
