The offshore operations require constant supply of materials and tools to facilitate daily work. ADMA-OPCO established the first supply base on Das in the early years of operations. The base was later moved to Saadiyat Island, off the city of Abu Dhabi, in the early 1970s. It continued its activity until the move in 1996 to the new base in Mussaffah area. Many activities take place at the base including receiving, dispatching, storing and shipping materials to all company sites and locations.
