The Suez Canal, a vital waterway connecting Europe and Asia, experienced a significant disruption in March 2021 when the container ship Ever Given ran aground, blocking the canal for six days. The incident resulted in a backlog of over 360 vessels, with estimated losses of $9.7 billion per day, according to a report by Allianz Global Corporate & Specialty. The blockage also led to a 10% increase in global shipping costs, highlighting the vulnerability of global supply chains to disruptions in critical waterways. The International Maritime Organization (IMO) has implemented various measures to enhance safety and efficiency in the Suez Canal, including the adoption of Resolution MSC.465(101), which requires ships to have an approved voyage plan in place before transiting the canal.

The Suez Canal Authority (SCA) has also implemented new regulations, including the requirement for ships to have a minimum of two tugboats accompanying them during transit, as outlined in SCA Circular No. 8/2021. This regulation aims to reduce the risk of grounding and enhance the safety of ships transiting the canal. Furthermore, the SCA has increased the number of pilots and tugboats available to assist ships during transit, which has resulted in a reduction of transit times by an average of 30 minutes, according to data from the SCA. The implementation of these measures demonstrates the efforts being made to mitigate the risks associated with transiting the Suez Canal and to enhance the resilience of global supply chains.

The importance of the Suez Canal to global trade cannot be overstated, with over 17,000 vessels transiting the canal in 2020, accounting for approximately 12% of global trade, according to data from the United Nations Conference on Trade and Development (UNCTAD). The canal's strategic location and the high volume of trade that passes through it make it a critical component of global supply chains. As such, disruptions to the canal can have far-reaching consequences, highlighting the need for carriers and ship owners to develop contingency plans to mitigate the risks associated with transiting the canal. The development of these plans is critical to ensuring the resilience of global supply chains and minimizing the impact of disruptions to the Suez Canal.

Supply Chain Disruptions

The disruption to the Suez Canal in 2021 highlighted the vulnerability of global supply chains to disruptions in critical waterways. The incident resulted in significant delays and increased costs for carriers and ship owners, with some vessels being diverted around the Cape of Good Hope, adding up to 15 days to their journey. The diversion of vessels around the Cape of Good Hope also resulted in increased fuel costs, with some estimates suggesting an additional $100,000 to $200,000 per vessel, according to a report by the International Chamber of Shipping (ICS). The IMO has implemented various measures to enhance the safety and efficiency of ships, including the adoption of the International Safety Management (ISM) Code, which requires ships to have a safety management system in place to identify and mitigate risks.

The ISM Code, which was implemented in 1994, requires ships to have a safety management system that includes procedures for identifying and mitigating risks, as well as procedures for responding to emergencies. The code also requires ships to have a designated person ashore (DPA) who is responsible for ensuring that the safety management system is implemented and maintained. The implementation of the ISM Code has resulted in a significant reduction in the number of accidents and incidents at sea, with a 25% reduction in the number of reported incidents between 2015 and 2020, according to data from the IMO. The code has also resulted in a reduction in the number of detentions of ships in ports, with a 15% reduction in the number of detentions between 2015 and 2020, according to data from the Paris Memorandum of Understanding (Paris MOU).

The development of contingency plans by carriers and ship owners is critical to mitigating the risks associated with disruptions to the Suez Canal. These plans should include procedures for diverting vessels around the Cape of Good Hope, as well as procedures for responding to emergencies, such as the grounding of a vessel. The plans should also include procedures for communicating with stakeholders, including customers and regulatory authorities. The BIMCO (Baltic and International Maritime Council) has developed a number of standard contracts and clauses that can be used by carriers and ship owners to mitigate the risks associated with disruptions to the Suez Canal, including the BIMCO Canal Transit Clause, which provides for the diversion of vessels around the Cape of Good Hope in the event of a disruption to the canal.

Contingency Planning

The development of contingency plans by carriers and ship owners is critical to mitigating the risks associated with disruptions to the Suez Canal. These plans should include procedures for diverting vessels around the Cape of Good Hope, as well as procedures for responding to emergencies, such as the grounding of a vessel. The plans should also include procedures for communicating with stakeholders, including customers and regulatory authorities. The IMO has implemented various measures to enhance the safety and efficiency of ships, including the adoption of Resolution MSC.1/Circ.1591, which provides guidelines for the development of contingency plans.

The guidelines, which were implemented in 2020, provide a framework for the development of contingency plans, including the identification of potential risks and the development of procedures for mitigating those risks. The guidelines also provide a framework for the communication of contingency plans to stakeholders, including customers and regulatory authorities. The classification society, DNV GL, has also developed a number of guidelines and recommendations for the development of contingency plans, including the DNV GL Contingency Planning Guidelines, which provide a framework for the development of contingency plans and the identification of potential risks.

The development of contingency plans is critical to ensuring the resilience of global supply chains and minimizing the impact of disruptions to the Suez Canal. Carriers and ship owners should work closely with regulatory authorities and other stakeholders to develop and implement these plans, which should be regularly reviewed and updated to ensure that they remain effective. The International Chamber of Shipping (ICS) has also developed a number of guidelines and recommendations for the development of contingency plans, including the ICS Guidelines for Contingency Planning, which provide a framework for the development of contingency plans and the identification of potential risks.

Implementing Resilience Measures

The implementation of resilience measures is critical to ensuring the resilience of global supply chains and minimizing the impact of disruptions to the Suez Canal. Carriers and ship owners should work closely with regulatory authorities and other stakeholders to develop and implement these measures, which should include procedures for diverting vessels around the Cape of Good Hope, as well as procedures for responding to emergencies, such as the grounding of a vessel. The measures should also include procedures for communicating with stakeholders, including customers and regulatory authorities.

The SCA has implemented a number of measures to enhance the safety and efficiency of ships transiting the Suez Canal, including the requirement for ships to have a minimum of two tugboats accompanying them during transit, as outlined in SCA Circular No. 8/2021. The SCA has also increased the number of pilots and tugboats available to assist ships during transit, which has resulted in a reduction of transit times by an average of 30 minutes, according to data from the SCA. The implementation of these measures demonstrates the efforts being made to mitigate the risks associated with transiting the Suez Canal and to enhance the resilience of global supply chains.

The development and implementation of contingency plans and resilience measures is critical to ensuring the resilience of global supply chains and minimizing the impact of disruptions to the Suez Canal. Carriers and ship owners should work closely with regulatory authorities and other stakeholders to develop and implement these plans and measures, which should be regularly reviewed and updated to ensure that they remain effective. By working together, the maritime industry can reduce the risks associated with disruptions to the Suez Canal and enhance the resilience of global supply chains.
