Honeywell ( has been awarded a $2.5 million contract from TonenGeneral Sekiyu (Tokyo, Japan) to oversee the company’s Wakayama Control House consolidation project, which will combine the oil refinery’s existing process control operations into one central location. In addition, TonenGeneral Sekiyu has selected Honeywell to monitor the projects for three other subcontractors who will manage distributed control system (DCS) relocation, civil structural, electrical, and instrumentation work. Honeywell also will provide its next-generation safety instrumented system (SIS), Honeywell Safety Manager, to ensure safe startup, operation, and shutdown.

TonenGeneral Sekiyu, a Japanese affiliate of global oil and gas company ExxonMobil, produces 917,000 barrels of oil a day at sites at Kawasaki, Wakayama, and Sakai. The company operates a chain of gas stations across Japan under the Esso, General, and Mobil brands.

Existing plant operations at Wakayama are distributed into three control buildings, which requires a large number of operating personnel. The site will relocate both the DCS and SIS to the central house to improve communication among the operation teams and increase system reliability.

Safety Manager — a component of Honeywell’s process control and automation platform, the Experion Process Knowledge System (PKS) — is the ideal safety solution for managing critical process control and safety shutdown functions. It integrates process safety data, applications, system diagnostics, and critical control strategies to ensure safety measures are effective in protecting people, the plant, and the environment.

Safety Manager will relay signals from the local control houses to the central control house. At the local control houses, Safety Manager will interface with existing emergency shutdown systems, which are based on relay logics.
