ESNAAD is a wholly owned subsidiary of ADNOC. The facility currently known as Mussafah Offshore Supply Base (MOSB) is strategically located at the Industrial hub of Mussafah approximately 40kms by road from the city center of Abu Dhabi. "ESNAAD" is not an acronym, as the Arabic name implies it means "Support".

The Base spreads over 148 hectares of fully developed land alongside the channel, with its state-of-the-art facilities. The company is well equipped to meet the challenge that lie ahead in supporting the oil and gas industry in the region operating in an era of modern technology.

The base operates 24 hours a day throughout the year and it provides security round-the-clock through an access control procedure and a highly sophisticated fire detection and fire lighting system.
