Rolls-Royce rolls out sophisticated situational awareness for navigators

Rolls-Royce is pioneering a major advance in ship safety with the introduction of our new Intelligent Awareness (IA) system.
IA is an advisory system that enhances the situational awareness of vessel surroundings, critical to decision making, through intelligent data fusion.
This enables safer operation in challenging and complex environments and improves operational efficiency.
Rolls-Royce is a pre-eminent engineering company focused on world-class power and propulsion systems.

Helping crews see the bigger picture :
Our pioneering Intelligent Awareness (IA) system represents a major advance in ship safety.
The system is the first of our Ship Intelligence, remote and autonomous solutions to be developed for commercial marine application.
Combining multiple sensors with intelligent software, IA is designed to mitigate the risks navigators face, especially in poor weather conditions, congested waters or at night.
Essentially, it gives the master and bridge personnel a supreme understanding of the ship’s surroundings.
IA builds on our extensive experience in research into autonomous vessels, gained through participation in the Advanced Autonomous Waterborne Applications project.

Seeing what the human eye cannot :
IA is particularly beneficial for the safe navigation of busy ports or challenging environments, such as dense fog causing poor visibility in busy shipping channels.
The system builds a 3D map of the vessel based on light detection and ranging (LIDAR), which uses a pulsed laser beam to measure distances.
Already in use in autonomous road vehicles, it links to GPS data to create 3D environments, allowing crews to ‘see’ what the human eye can’t.
LIDAR creates a ‘point cloud,’ firing about 300,000 beams of light from a laser and then measuring the time taken to reflect them back to source to render a 3D map.

Further spatial information is gathered from on-board HD cameras, linked to software which can identify vessels or objects and apply learning algorithms to determine characteristics, such as how fast a vessel travels or stops.
LIDAR, GPS, camera data, radar and AIS combine through what we refer to as “data fusion” to provide those controlling the ship with a complete overview of its surroundings.
A ship’s crew can then switch between a 3D map rendered by LIDAR, a radar overlay or a topographical view of the seabed.
