Wilhelmsen Ships Service’s smart ropes employ Nordic’s nRF52840 multiprotocol SoC to wirelessly transmit long-range load data to ship
Nordic Semiconductor today announces that Wilhelmsen Ships Service, a Lysaker, Norway-based shipping company, has specified Nordic’s nRF52840 Bluetooth® 5/Bluetooth Low Energy (Bluetooth LE) advanced multiprotocol System-on-Chip (SoC) for its ‘Timm Mooring Assistance’ smart ropes, designed to assist ship crews when mooring vessels in port.
The Timm Mooring Assistance set-up comprises up to 22 ropes—depending on the size of the vessel being moored—each fitted with a single load sensor to provide
feedback on safety and efficiency parameters. For example, the load and temperature data can alert crew members to the load distribution between individual ropes, safety alerts for potential rope snaps, as well as predicting the lifetime of individual ropes. Access to this data allows the crew to take immediate corrective action in case of a problem.
In operation, sensor data from the ropes is wirelessly relayed to a ‘collector box’ on the vessel using Bluetooth 5 technology’s long-range feature enabled by the nRF52840 SoC. The collector box comprises a Bluetooth LE-equipped Ethernet router which relays data to the vessel’s bridge via a wired local area network (LAN) for immediate analysis by crew members via a dashboard on a connected tablet or PC.
