The ship’s alarm and surveillance system provides information to the operator on the condition of the power plants, ancillary machinery and equipment. Peripheral panels with duty change watch system and alarm indication are integrated.
Panels are located in the engine control room, on the bridge, in public rooms and cabins. A bridge navigation and watch alarm (BNWAS) is also included.
Acon is integration/interface-ready for any vessel type and ship system or equipment via standard protocols. The Acon user interface is tailored to the ship and gives the user access to the underlying ship systems through an ergonomic standardised interface specifically designed for easy and safe operation.
Multifunctional displays allow the operator to choose which information is to be collected and presented together with class defined critical information.
All Rolls-Royce products are based on the common control platform and communicate via the Rolls-Royce ship integration network.
What next...
Integrated Automation System (IAS)
Acon products are normally delivered as integrated automation systems with multifunctional operator stations - Acon IAS. Third party equipment or systems like HVAC, fire and gas etc. are easily interfaced to Acon IAS for control and monitoring.
The Acon IAS user interface is tailored to the ship with access to the underlying ship systems through an ergonomic standardised interface specially designed for easy and safe operation.
Alarms
Alarm and monitoring can be a part of the Acon IAS or a standalone system. It is modular and suits all type of ships.
Peripheral panels with watch call system and alarm indication are integrated for operation with unmanned machinery spaces. A ‘dead man’ system with separate panels is part of the alarm product portfolio.
Cargo and Machinery Control
Control and monitoring of main machinery (fuel, lubrication, air, cooling etc) and power distribution are all controlled by the ACON system. Fuel control system for LNG fuelled engines can also be part of the system.
Cargo and machinery control are also part of the Acon systems capability. Pumps, valves, compressors etc. are monitored and controlled via the intuitive mimic pictures at the Acon operator stations.
The mimic pictures are tailored to the actual vessel cargo, machinery and LNG installation. Logical grouping of information combined with colour codes on the Acon screen makes the operator interface clear and easy to use.
Fuel System Control & Monitoring (LNG)
Our LNG control and safety systems handle the safe and secure supply of LNG to the engine. Additional systems include gas detection and shut down. Different operational modes like bunkering, supply and standby are supported.
Tank Sounding
A tank sounding system can be an integral part of the Acon IAS, or a standalone system, and are designed for both pneumatic sounding and/or any kind of electronic tank sensor.
The system is designed to respond to the Acon control when operating the cargo system by automatically prioritising sounding of the actual tanks. A number of tank views keeps the operator fully informed on tank status.
Bridge Navigation Watch Alarm System (BNWAS)
This system will monitor bridge activity in order to detect the operator’s inability disability to prevent marine accidents. The system is according to the requirements in IMO MSC 128(75), and DNV NAUT-OSV rules.
Central Alarm System is connected to equipment on Bridge, which makes audible alarms, and all alarms can be silenced from the Operator Panel. Bridge Watch System will ensure the continuous monitoring of the Bridge operator’s fitness during One Man Bridge operation. BNWAS will alarm the backup-up officers if no action is taken from bridge.
