About Shikoku Operations

Shikoku Operations

Shikoku Operations has worked actively to upgrade, expand, and also rationalize its operation to respond to different demands for petroleum. For steady progress in the future, Shikoku Operations believes that "petroleum, which is widely utilized not only in our daily life but also in industrial activities, must be supplied stably and must be of good quality and be environment-friendly." Shikoku Operations is ISO 9001 (quality management system) and ISO 14001 (environmental management system) certified.
