Racal-Decca ISIS Engine Room Monitoring Systems Chosen For Aramco Arabian Gulf Support Fleet

Racal-Decca Marine has won a contract to supply ISIS 250 engine room monitoring systems for a new series of vessels (four docking tugs and two mooring boats) being built for Saudi Aramco tanker-handling operations at Ras Tanura in Saudi Arabia. The four docking tugs will be 134.5 feet (41 m) long and will be used for tanker docking, while the two 107- foot (32.6 m) vessels will be used for heavy weather mooring services. All six vessels are currently under construction at the Belgian Shipbuilders' Corporation yards at Fulton and Langebrugge with the first vessels scheduled for delivery in the second half of 1994. The ISIS 250 alarm and monitoring systems being supplied by Racal-Decca will employ a distributed system in which Local Scanning Units are mounted adjacent to the machinery under surveillance. The systems will monitor the main propulsion and auxiliary machinery on all of the vessels and also provide generator controls aboard the larger tugs. System information is presented to the operators through the use of enhanced trending and graphic displays which take advantage of the increased capabilities of the new ISIS 250 Master Series VDU workstations. The new contract brings the total number of ISIS-equipped vessels in service with Saudi Aramco at Ras Tanura to 11. For more information on Racal-Decca,
