WSC Efforts Aim to Further Reduce Low Levels of Containers Lost at Sea

Despite several high profile incidents recently, a new survey of the container shipping industry by the World Shipping Council (WSC) reports that the incidents of containers lost overboard has been on the decline and is a small percentage of the total annual volume. The WSC also outlines a number of initiatives to further enhance container safety.

Containers lost overboard represent less than one-thousandth of one percent of the roughly 226 million containers transporting $4 trillion in cargo currently shipped each year according to the WSC. Looking at data for the past 12 years contributed by shippers that represent approximately 80 percent of the industry, and extrapolating it to represent all shipping, the WSC reports that the three-year moving average is declining, halved to an average annual loss of 779 containers lost overboard between 2017 and 2019.

The WSC concludes based on data from the past 12 years that half of all containers lost at sea are attributed to a limited number of major incidents that have occurred during those years. Some carriers reported no lost containers while others noted significant incidents where hundreds of containers were lost in a single accident. With more than 6,000 ships around the world carrying containers at any point in time, the WSC previously distinguished catastrophic losses as 50 or more containers lost in a single incident. However, the 2020 data no longer differentiates catastrophic losses.

In the period between 2008 and 2019, the WSC estimates that there were on average a total of 1,382 containers lost at sea each year. The lowest point was between 2008 and 2010 with an average of 675 losses per year, quadrupling to an average of 2,683 between 2011 and 2013, declining to an average of 1,390 between 2014 and 2016 and again down to an average of 779 between 2017 and 2019. The numbers were however impacted by several significant losses, including 900 containers on the Rena (2011), 4,293 containers on the MOL Comfort (2013), 517 containers on the El Faro (2015), and a few incidents in 2018 and 2019 that each lost more than 100 containers.

Summary of containers lost at sea - World Shipping Council

Recognizes that all containers lost at sea represent safety and environmental hazards regardless of how and when those containers were lost, the WSC points to efforts between government and other stakeholders to enhance container safety. Among these, they highlight the 2016 changes to the SOLAS convention that require verification of container weights before packed containers may be loaded aboard ships. The WSC also anticipates efforts to further revise and enhance the 2014 code of practice for packing of cargo transport units as well as future revisions to the 2015 ISO standards for container lashing equipment and corner casting.

The WSC repeats a proposal it made to the IMO in 2019 to align container stacking requirements to eliminate discrepancies that might have significant safety implications. It says that those discrepancies might contribute to the potential for the collapse of container stacks and container loss at sea. 

At the same, the WSC is also participating in efforts to revise the IMO guidelines for the inspection programs for cargo transport units including containers, and is also co-sponsoring with the European Union a proposal to the IMO for mandatory reporting of containers lost at sea. 

The World Shipping Council concludes the survey report saying that carriers will continue to explore and implement preventive and realistic measures to bring container losses as close to zero as possible and welcome continued cooperation from governments and other stakeholders to accomplish this goal.
