Oil in Kenya was first discovered by the British Company, Tullow oil, in the Lokichar basin in 2012. Since then, Kenya has signed sixteen Production Sharing Contracts (PSC) with the company. The PSC provides for decommissioning obligations but the decommissioning laws of the country are not yet fully developed to deal with environmental consequences. Decommissioning, if not well done may lead to serious environmental damage and economic loss. In order to come to a decision on the best decommissioning strategy for installations and structures in the oil field, a high degree of care is required so as to safeguard the environment, allow for safe navigation and the overall protection of the marine ecosystem.
