Theme 2 : Shipbuilding and leisure boat building

On board ship, safety is a major concern. Surveillance systems and alarms contribute to safety by providing crew members with permanent and effective means of vessel monitoring. These safety systems operate using sensors positioned throughout the ship to provide information on its functioning – checking for leaks, gauging tank levels, monitoring navigation lights and engines, verifying smooth running of pumps, etc. The sensors relay the captured data via cable to communication interfaces that can be accessed by crew or passengers. The complex network of cables involved is costly to produce, install and maintain and adds significantly to the vessel’s weight.

As a way of lightening ships and thereby reducing energy consumption, the SAPHIR project will develop a wireless network to be installed on board and linking sensors and alarm units. Working with the architects responsible for ship fitting, the project will incorporate the network into ship design from the drawing board stage, enabling it to be reliably and more cheaply upgraded and maintained throughout its life cycle.

While onshore wireless communication can now call on well-developed technologies, its application at sea continues to rely heavily on the interior layout of ships and the ease of radioelectric wave propagation in their complex and confined environments.
