The Obvious Idea that Slashes Shipping's Climate Impact

Revolutionizing Shipping with Slower Sailing

The shipping industry, responsible for around 2% of global CO2 emissions, faces a critical challenge: how to reduce its environmental impact. One effective strategy is slower sailing, which has shown promising results in reducing emissions and saving costs.

A Case Study: The California Traffic Jam

In late 2021, a massive containership traffic jam off the coast of California highlighted the benefits of slower sailing. Ships received queue numbers to time their port arrivals, reducing congestion and cutting CO2 emissions by approximately 460,000 tonnes. This experience suggests that a broader implementation of slower sailing could significantly benefit the environment.

The Blue Visby Solution

The Blue Visby Solution aims to optimize ship arrivals by tracking port traffic and weather conditions. This system helps ships convert waiting time into sailing time, reducing emissions without delaying overall transport times. A recent trial showed CO2 reductions of 7.9% to 28.2%, demonstrating the system's potential.

Overcoming Challenges

Slower sailing faces logistical and economic hurdles. The "sail fast, then wait" approach is driven by economic incentives to ensure timely cargo deliveries. However, innovations like Blue Visby Solution can address these challenges by ensuring precise scheduling and minimizing delays.

Broader Implications

Beyond slower sailing, the shipping industry can adopt other measures to reduce emissions. These include using wind-capturing devices, applying smoother hull coatings, and optimizing routes. However, political and economic barriers, such as geopolitical instability and market pressures, must be addressed to ensure widespread adoption.

Conclusion

Slower sailing presents a viable path to reducing shipping emissions and achieving climate goals. With continued innovation and strategic implementation, the shipping industry can navigate its way toward a more sustainable future.

 Slowing down ships can significantly reduce shipping emissions and save costs. This strategy, trialed successfully during the 2021 containership traffic jam off California's coast, highlights a promising way to make shipping more sustainable.

FAQs

1. How did slower sailing help reduce emissions during the 2021 traffic jam off California?

• Ships were given queue numbers, enabling them to time their arrivals when berths were ready, instead of rushing and waiting. This reduced average sailing speeds and saved approximately 460,000 tonnes of CO2 emissions.

2. What are the potential benefits of implementing slower sailing more widely?

• Slowing down ships by 10% can cut emissions by around 20%. This not only reduces CO2 emissions but also saves fuel costs.

3. What challenges does slower sailing present?

• Slower sailing can cause logistical and economic challenges, such as longer journey times and the need for accurate scheduling to ensure timely port arrivals.

4. How does the Blue Visby Solution address these challenges?

• Blue Visby Solution helps ships time their arrivals by tracking port traffic and weather conditions, converting waiting time into sailing time without delaying overall transport times.

5. What were the results of the Blue Visby Solution trial?

• In a trial with grain ships, CO2 emissions were reduced by 7.9% to 28.2%. Although there were minor communication hiccups, the trial was considered successful.

6. Why is the "sail fast, then wait" approach still common?

• Economic incentives drive this approach to ensure ships are ready when needed. Delays can be costly for industries reliant on timely cargo arrivals.

7. Are there other methods to reduce shipping emissions?

• Besides slower sailing, ships can use wind-capturing devices, smoother hull coatings, and optimized routes to avoid tidal currents and adverse weather.

8. What are the barriers to adopting slower sailing?

• Political instability, such as Houthi attacks in the Red Sea, forces ships to take longer routes, increasing emissions. Economic forces also push for faster sailing to meet demand and manage freight rates.
