function/task analysis and simulations were carried out, mapping issues and testing design optimisations. Ten participants were typically used for each hour-long simulation study, says Bjørneseth. Results and data continue to be received


from the first functioning iteration of the Unified Bridge concept on Stril Luna, but its captain, Lars Aure, has said: “Controls are easy and logical to handle and information presented on the screens is clear,” adding that “the Unified Bridge takes the working environment seriously, and helps to give better working conditions onboard and safer operations.”


Ongoing developments The Unified Bridge system has been delivered to two megayachts used for leisure purposes that are also capable of undertaking luxury expedition support. Tese vessels have been fitted with forward facing Unified Bridge consoles holding two workstations, one for navigation and one for monitoring and support. Te bridge consoles have four large 26” displays in close proximity to the operators and some smaller 10” touch displays for smaller applications. Rolls-Royce has delivered an ACON automation system, Rolls-Royce dynamic positioning system and the propulsion system including levers for DP and manoeuvring control, all with the new Unified Bridge design. In addition, the Rolls-Royce ACON


Bridge Control (ABC) system has been delivered. This system allows operators


to control the windscreen wipers, lanterns, search lights, CCTV, bridge ceiling lights and decklights from a software application on one of the 10” touchscreens. There is also a single interface for alert, easing the captain’s workload and increasing comfort. An overhead console supplements the


floor mounted consoles, and is situated in the ceiling in front of the operators. Tis holds larger 26” monitors to give a good placement to display the vessel’s CCTV cameras feeds, conning display and DP system monitoring. “Te bridge concept provides the captain and his bridge crew with a state of the art user experience both during navigation and other activities and fits the vessel’s operational profile perfectly,” says Rolls-Royce. Another Unified Bridge has been


installed on a 128m long subsea Inspection Maintenance and Repair (IMR) and construction vessel. Te vessel is equipped with a Unified Bridge on all bridge workstations (forward, aft and bridge wings). The aft workstations are where the


operations on the aſt deck are monitored and controlled, and where it is important that the operator has a good working environment to support them through their watch. An overhead console gives the operator full overview of information which is mainly for monitoring purposes. The vessel features two separate aft workstations equipped with Rolls-Royce dynamic positioning systems, Rolls-Royce UniCon (unified propulsion control), the


Rolls-Royce ACON automation system, and the ABC system for controlling auxiliary equipment. The forward workstations, of which


there are also two, have divided duties; one is for navigational purposes and the other is for watch keeping and support with access to manoeuvring control and the DP system. To aid accessibility, the Integrated Navigation System (INS) equipment is within easy reach for the operator and the display unit configuration is as described above (both forward and aſt) with large 24”/26” monitors mounted in the consoles within easy reach. Monitors utilised for radar/ECDIS purposes must be 26” to adhere to the regulations. Te wing stations are smaller stations


with a smaller overhead console and a smaller Unified Bridge console adapted to wing operations (docking, operations from the flank of the vessel). UniCon and ABC systems are available in addition to a sensor display. Tis is a collection of different sensors gathered in one display to save space and to move space demanding equipment to a secondary location, optimising the operator experience. For this vessel an additional feature called


Unified Monitoring was included in the ABC system. Tis feature enables operators to bring up any application on any display unit (depending on classification), easing communication across the bridge. Following further research into


ergonomic requirements the latest consoles are height adjustable and can be adjusted to the height of any operator while complying with standards NORSOK S-002, ISO 11064 and NAUT-AW, NAUT-OSV. The consoles can be combined with the typical Unified Bridge consoles for forward/aft bridge and also utilised to form an office landscape on the bridge for large vessels (e.g. cruise vessels) where this might be a requirement.

system in a rolling programme of research that may potentially lead to new console development and a focus on bridge office space. Te company is currently analysing the suitability of its Unified Bridge concept for MPVs, large construction vessels, drill ships, anchor handling vessels, PSVs, as well as passenger vessels. NA
