BLOG: Using tech to generate sustainability in cruise by theICEway

AdobeStock_376229935 (1).jpeg
In IT for cruise, there is a burning question to answer as we approach 2023. How can we leverage technology to generate sustainability within the cruise industry? Recent tech innovation has led to increases in bandwidth, huge changes in the guest experience and so much more. But how many IT-related developments have had a positive impact on the environment? How many initiatives have been green? Here we look at key examples of companies using tech to generate sustainability in cruise.

Cruise Lines Aim For Net Zero

Before we get to examples of ‘green technology’, it is important to look at where the industry is right now. What are the main objectives? Cruise Lines International Association (CLIA) cruise lines are working towards net zero carbon cruising by 2050. There are three key areas to work on to achieve that objective:

  • Reducing the carbon footprint of ships at berth and at sea
  • Investment in advanced environmental technologies onboard
  • Working with cities and ports on sustainable destination management

Similarly, there are three key strategies being deployed around fuel, electricity and wastewater.

Fuel

Liquified Natural Gas (LNG) has virtually zero sulphur emissions and offers a 95% to 100% reduction in particulate emissions. Further to that, it also has an 85% reduction in NOx emissions and up to a 20% reduction in greenhouse gas emissions. More cruise lines are therefore increasing the number of ships that can utilise LNG for primary propulsion.

The cruise industry is also exploring other sustainable marine fuels and propulsion techniques. Biofuels, biodiesel, methanol, ammonia, hydrogen, and electric batteries are just a sample of what is currently being investigated. Hybrid solutions are another tactic being implemented to lower the carbon footprint of voyages. According to CLIA, over 15% of new vessels being launched in the next five years will be equipped to incorporate fuel cells or batteries.

Electricity

Cruise lines are investing heavily in shoreside electricity solutions, with the majority of new ships able to plug in to shoreside electricity. Further to that, 98% of new build capacity through to 2028 is committed to be fitted with shore-side electricity systems or will be configured to add shore-side power in the future.

Wastewater

According to CLIA, advanced wastewater treatment systems are often equivalent to the best shoreside treatment plants. Currently, 78% of the CLIA cruise line fleet capacity is served by advanced wastewater treatment systems. It should also come as little surprise to then note that 100% of new ships on order are specified to have them.

Innovations To Support These Strategies

Using tech to generate sustainability and achieve a greener future has seen the cruise industry also embracing further innovations and practices, including:

  • Exhaust gas cleaning systems
  • Air lubrication systems for ship hulls
  • Energy-efficient engines
  • Advanced recycling systems and practices
  • Tinted windows, higher efficiency appliances, HVAC systems, LED lighting and more

How Technology Can Be Leveraged To Generate Sustainability Within The Cruise Industry

Let’s look then at some examples of ‘sustainable tech’ in action. There are far too many to cover in full here, but we believe some of the most impressive companies using tech to generate sustainability are as follows:

  • Virtual anchoring from Aurora Expeditions
  • A heat power system designed to convert engine heat to electricity from Virgin Voyages
  • Sea Dream Yacht Club’s silent, emission-free battery pack
  • Hurtigruten’s battery-hybrid powered ships
  • Viking ships renewing energy onboard
  • Celebrity Cruises’ many sustainable onboard features
  • NCL’s Sail & Sustain program
  • Royal Caribbean’s Hydrothermal Oxidation Technology

Aurora Expeditions

With the Greg Mortimer Expedition Ship, Aurora boldly claims to have “redefined expedition cruising for the future.” They may be not far off the truth in that, as the impressive ship has some fantastic facilities and technical features. These include virtual anchoring, achieved via a combination of GPS, steering technology, propellers and then also thrusters. Greg Mortimer can essentially hold its position without a traditional anchor, thus minimising damage to the sea floor.

Virgin Voyages

In a bid to maximise fuel savings, Scarlet Lady features a Climeon heat power system. The system generates clean electricity via the use of low temperature wasted heat from engine cooling water. It includes six 150 KW modules and has an overall electric power generation of 0.9 MW. Traditional heat power solutions operate at higher pressure levels and are larger in size and less efficient at low temperatures. The Climeon system can effectively deliver up to 50% higher efficiencies than the other solutions currently available.

Sea Dream Yacht Club

Sea Dream Yacht Club received a $1.8m (£1.2m) grant from Enova SF, a state enterprise owned by the Norwegian Ministry of Climate and Environment. The grant was awarded to help them build the ultra-luxury SeaDream Innovation. Launched in 2021, the ship incorporates technologies that are considered to be extremely environmentally friendly. These include a battery pack enabling the ship to sail silently and without emissions for up to three hours.

Hurtigruten

Hurtigruten’s battery-hybrid powered ships can sail with electric propulsion for 15-30 minutes. The technology combines with the construction of the hull and an effective use of electricity on board to reduce fuel consumption and CO2-emissions from the ships by up to 20%. Effectively, this equates to over 3000 metric tons of CO2 per year.

Viking

Many of Viking Line’s ships renew energy onboard, meaning that the heat emitted from their engines is not wasted. The company has also invested $447 million in two new vessels, Viking Grace and Viking Glory. Each one reduces carbon dioxide emissions by up to 30% per nautical mile. Powered by LNG fuel, Viking Grace reduces emissions of nitrogen and particulate matter by 85 per cent and greenhouse gas emissions by 15 per cent*. Viking Glory actually produces 10 per cent fewer emissions than its sister ship.

*Compared to vessels running on oil fuel

Celebrity Cruises

Celebrity ships have a variety of sustainable onboard features. For example, their LED lights last longer than halogen bulbs and give off less heat. Energy-efficient appliances including coffee makers and ice makers are complimented by energy-efficient windows that help air conditioning run more efficiently. They have also deployed water-reduction technology in showerheads, cabin sinks and dishwashers. Their Solstice ships are outfitted with solar panels to help with renewable energy onboard.

NCL

Norwegian Cruise Line is committed to preserving the oceans. Their mission is to protect the environment, people, and communities on every NCL voyage. They have injected sustainability into all day-to-day operations, with a core focus on three areas:

  • Water Stewardship & Conservation
  • Waste Mitigation
  • Energy Conservation

The NCL Sail & Sustain programme utilises new technologies and innovations such as the Exhaust Gas Cleaning System (EGCS). This reduces SOx emissions by up to 99% by cleaning emissions before they are then released from the stack.

Royal Caribbean Group

Royal Caribbean Group installed Hydrothermal Oxidation Technology on Celebrity Apex in 2020. The pilot for this prototype for food waste treatment ran throughout 2021 and was designed to enable ships to treat food waste without discharging it to sea.

The practice of using tech to generate sustainability is becoming ever more commonplace, and with good reason. Corporate Social Responsibility (CSR) is being embraced with increasing fervour by organisations both large and small. Gone are the days of excess where potentially damaging practices are acceptable, replaced now by a genuine desire to be responsible. What then does the future hold? Only time will tell, but it is clear that cruise is heading in the right direction.
