Steps to Reduce Carbon Emissions in the Shipbuilding and Shipping Industry

5 ноября 2021, 10:28

The COVID-19 pandemic has been an ongoing struggle for the maritime industry, but it’s not the only concern. Decarbonization of shipping has also been a significant challenge and can potentially reduce GHG emissions. 

The shipyards are thus taking necessary steps to decarbonize with new and improved technologies. At the same time, manufacturers have invested heavily into electric engines that charge up quickly on shore power or batteries, so they’re useful when needed out at sea. 

For instance, the Marshall Islands intends to reduce emissions by 100% in twenty years, while India and Saudi Arabia want no cap on emissions. Here are some strategies that may help the entire industry accelerate reduction in carbon emissions:

1. Focusing on Data and Seeking Alliances

The IMO has a good solution for achieving decarbonization. The use of data is crucial to monitor greenhouse gas emissions and identity sources with real-time precision. These aims will no longer be deadlines set in the future. Satellites, remote sensing technologies, and artificial intelligence will clarify worldwide emissions at every moment while pinpointing them down to specific locations like ports/ships/businesses, etc. 

The initiation of alliances aimed at zero emissions is a milestone for the industry and plays an essential role in the development of green shipping. One such cooperation, Getting To Zero Coalition (GZC), has been building momentum in recent years by developing collaborative efforts with various stakeholders across their field. 

GZC was founded due to a call for action in support of decarbonization which called out 70 leaders from maritime companies and banks and other players who have pledged support towards achieving this goal over three phases up until 2030. 

2. Route Optimization

The shipping industry had to resort to route optimization in the quest to find new ways to cut back on carbon emissions. According to a study by the Norwegian University of Technology (NTNU), route optimization would cause limited disruption but improve emissions per vessel as high as 5%. This method includes improving hull design, propeller optimization, and waste heat recovery. 

3. Focus on Renewable Energy

Wind power is an ever-present source of renewable energy, but it has few applications for everyday life. However, innovators like Cargill and Wessels have trailed kite systems to harness wind’s potential as a means of propulsion after years of research and development.

Overall, the maritime industry—historically known for being a high CO2 emitter—must now face the challenge of complying with IMO regulations before 2030 and 2050. The effects will not be felt only by owners and charterers. Shipyards might also need to update their designs to stay competitive with performance improvements over time.
