Management of Change – Drilling Operations BP’s DWOP required that any significant changes to a drilling plan “shall be documented and approved via a formal management of change (“MOC”) process.” 436 This requirement was reinforced by the BP golden rules, which require that “work arising from temporary and permanent changes to organization, personnel, systems, process, procedures, equipment, products, materials of substances, and laws and regulations cannot proceed unless a MOC process is completed.” BP required the MOC process to include: (1) a risk assessment conducted by all affected by the change; (2) a work plan that included details regarding control measures to be implemented for equipment, facilities, process, operations, maintenance, inspection, training, personnel, communication, and documentation; and (3) authorization of the work plan by responsible person(s). 437 Despite the company’s careful documentation of the importance and necessity of the MOC process, the Macondo team did not use this process to manage important changes occurring in day‐to‐day drilling operations.
