ABB and Royal Caribbean Group collaborate to make emergency stops safer and more efficient
The world’s largest cruise ship Wonder of the Seas, departed on her maiden voyage in the beginning of March 2022, she was the first in the world to feature the new ABB Ability Marine Braking Assistance. Designed for safe and smooth emergency stops, the automatic braking system is the result of collaboration between supplier and owner, initiated at Royal Caribbean Group’s request, according to ABB's release.
Following full sea trials by shipbuilder Chantiers d’Atlantique and acceptance by the owner, the DNV-approved Marine Braking Assistance provides the latest example of how technology can be leveraged to improve safety for ships, seafarers and passengers.
Marine Braking Assistance, through the push of a button triggers an automated braking sequence, optimizing the angles and power of all the Azipod propulsion units based on vessel position, heading and speed to allow maximum braking efficiency. Critically, operators have time to attend to other urgent matters while retaining control over steering.
The Marine Braking Assistance can be compared to an automated braking system (ABS) whose safety benefits car drivers today expect as standard. Automation of the braking sequence also minimizes the wear and tear systems experience due to vibration cavitation and the heating up of braking transformers under manual control.
For a vessel equipped with podded propellers, the pod way emergency stopping procedure allows much faster stopping, with limited steering ability, but it demands step-by-step manual actions by the helmsperson, at a moment when other issues require immediate attention.
ABB’s Process Automation business is one of the leaders in automation, electrification and digitalization for the process and hybrid industries.
