ABB And Royal Caribbean Group Collaborate To Make Emergency Stops Safer And More Efficient

  • ABB Ability™ Marine Braking Assistance helps ships minimize stopping time and distance, without compromising steering capability
     
  • Initially developed at the request of Royal Caribbean Group, the new digital solution improves safety for ships, seafarers and passengers
     
  • Automated braking saves wear and tear on critical ship control systems

As 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.

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.

“We at ABB take great pride in introducing new technologies to the industry to improve safety and add value for our customers. Marine Braking Assistance is a good example of a co-creation project where we, in close collaboration with Royal Caribbean Group, developed a solution that makes a real operational difference,” said Kalevi Tervo, Global Program Manager of ABB Marine & Ports. “The adoption of an automated process that improves safety holds special significance at a time when regulators are moving forward on rulemaking for autonomous ships.”

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.

Hard stopping a ship in an emergency situation can be highly stressful. Unlike slamming on the brakes of a car, for vessels with shaftline propulsion the turn to full astern results in losing steering ability. 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.

Anders Aasen, Vice President, Global Technical Operations, at Royal Caribbean Group states: “We have a long history of innovating to improve maritime safety. I am pleased to debut Marine Braking Assistance technology onboard our ships through close cooperation with ABB.”

Carnival Corporation: More Efficient and Sustainable

“Our number one goal is reducing our emissions,” said Bill Burke, a chief maritime officer at Carnival Corporation.

That goal is a 40 per cent reduction in the company’s carbon emissions by 2030 when compared to a 2008 baseline, with carbon levels peaking for Carnival in 2011.

It’s a combination of efficiency and sustainability, Burke said.

That involves not only new efficient ships but finding more efficient equipment for the company’s existing fleet, making sure ships are operated well, meaning the right speeds, with the right engine loads.

“Voyage planning is another area where we are focused,” Burke said. “That sort of thing is ‘free,’ if we can get it right, it’s free savings.”

Burke has his sights set on HVAC system improvements as a key area where the company can save money on fuel and cut carbon emissions.

“The efficiency of the equipment has increased in the last few decades. If we haven’t already, we change out chillers and HVAC equipment,” he said.

One megawatt of savings translates roughly to about $1 million annually in fuel, Burke said.

“It’s then the money we can use for other things … it’s seed money to make ships more efficient.”

New Ships Get Efficient

New ships are generally 20 per cent more efficient per passenger than the last class, and that starts with the hull design, Burke said.

Then it’s a process of looking for the best and most efficient equipment fleetwide, with Carnival Corporate Shipbuilding in the UK focused on the job.

With the new deliveries of the AIDAnova, Costa Smeralda, Carnival Mardi Gras and P&O Iona, Carnival sister brands now have four technically identical new ships on the Carnival XL platform. Expect a lot of note comparing.

“We will compare performance, but a lot of that comes down to the itinerary,” Burke said, noting variables such as the speeds the ships travel at plus climate conditions driving air conditioning use.

Trying to compare performance, the company uses climate zones to normalize energy use when reviewing data.

That data becomes easier to use with ships in port, without a propulsion load, with Carnival now asking its brands to operate on just one generator while in port.

“The brands will make adjustments and we will help them with targeted investments to reduce the hotel load to allow them to first operate on one generator (in port) and then get the load lower. We’ve dropped the electrical load down by several megawatts.”

Ships are compared against each other with adjustments for size and climate conditions, with Carnival using its own port power coefficient to measure power usage by ship while docked.

2030 Goal

By 2030 Burke envisions what he called a green fleet with nearly 20 per cent of Carnival Corporation ships powered by LNG.

“Both LNG and non-LNG ships would get some portion of their fuel from biofuels. Batteries would be on a number of ships for peak shaving and non-LNG ships would operate advanced air quality systems (scrubbers),” Burke said.

Those ships running scrubbers would have wash-water filtration and significantly reduced particulate.

“All ships would have achieved our port power coefficient goals and easily operate in port in all climate conditions on a single diesel generator, indicating efficient port hotel service operations.”

Another project is a single fleet-wide maintenance and procurement system.

“That will allow us to better leverage our scale and remove excess inventory.”

Burke also plans to add more courses to the company’s Arison Maritime Center (CSMART) in the Netherlands.

“In addition to operational team training for our officer core, we do have energy efficiency training and we will expand that.”

Many ships, continued Burke, will have air lubrication systems, adding that around 60 per cent of the fleet will be able to plug into shore power by 2030. Another three-quarter of the fleet will have advanced wastewater purification systems, and all ships will have food waste digesters.

“Our ships will be completely instrumented for measuring the efficiency of our largest power consumptions … you have to be able to measure (consumers) to know how you’re doing.”

Data will result in self-correcting behaviour that will improve operational efficiency, according to Burke, who said the ships will continue to get more sensors and measuring capability.

“We will be well on our way to designing and building our first zero emissions and zero discharge ship … that’s the biggest challenge and we hope our work with LNG will have us well prepared for that next fuel.”
