Built by STX Finland, at its Turku yard, and designed for cruising the shallow waters of the Finnish and Swedish archipelago, Viking Grace is the world’s largest LNG-fuelled ferry.
Having entered service in January 2013 the vessel will be able to operate in compliance with stringent 2015 Baltic regulations on gas emissions.
The NACOS Platinum bridge system comprises four S- and X-band radars linked to a series of five Multipilot, Chartradar and ECDIS pilot multifunction workstations for control of all main radar, ECDIS and conning operations, in addition to those for automatic steering and voyage planning.
Supplementary workstation consoles and displays are located at starboard and port wing areas as well as in the captain’s cabin. Secondary sensors, consisting of AIS, VDR, DGPS, doppler log and echosounder navaids, also include SAM’s new Bridge Navigational Watch Alarm System (BNWAS).
A dedicated communications network connects to multifunction workstations in the engine control room and on the bridge, while L-3 Valmarine’s Valmatic Platinum integrated automation system will provide control of all machinery, and includes added capabilities for vessel power management and emergency shutdown.
In addition, the system also includes four control/monitoring workstations around the vessel and a ship-wide network for monitoring access via portable multifunction workstations.
Also interfaced via redundant connections to the communications network is an Emergency Shutdown System (ESD). An independent facility based on the same platform, it operates its own process control station communications network, remote IO units, hard-wired control panels and associated workstations.
