1.1 The Background to the Study

Sea tides have a significant impact on port performance, affecting the safety, efficiency, and sustainability of maritime operations. tides can influence the depth of water, currents, and waves, making it challenging for ships to navigate and berth safely (Pianc, 2018). This paper discusses the implications of sea tides on port performance Safety Risks, Sea tides can pose safety risks to ships, crew, and port infrastructure. For example, high tides can cause ships to collide with quay walls or other vessels, while low tides can expose hidden obstacles or shallow waters (IMO, 2019). tides can affect the operational efficiency of ports by influencing the time and manner in which ships can enter or leave the port. For instance, high tides can limit the draft of ships, while low tides can restrict the accessibility of certain berths (UNCTAD, 2019).

Sea tides can also have environmental implications for ports, such as increased erosion, sedimentation, and water pollution. For example, high tides can cause flooding in nearby coastal areas, while low tides can expose sensitive habitats (IPCC, 2019).  Many ports are investing in infrastructure adaptations, such as dredging, seawall construction, and quay wall reinforcement, to mitigate the impacts of sea tides (World Bank, 2020), advanced tide prediction and monitoring systems are being implemented to provide real-time information on tide levels, currents, and waves, enabling ports to optimize their operations and minimize risks (IHO, 2020), the global port community is promoting sustainable port management practices, including the use of renewable energy sources, reduction of greenhouse gas emissions, and implementation of environmentally friendly technologies (ESPO, 2020), Sea tides have significant implications for port performance, affecting safety, operational efficiency, and environmental sustainability. As the global port community continues to address the challenges posed by sea tides, it is essential to prioritize collaboration, innovation, and sustainability to ensure the long-term resilience and competitiveness of ports worldwide.

Africa’s coastal regions are home to many of the continent’s most important ports, which play a critical role in facilitating international trade and economic development. However, these ports are also vulnerable to the impacts of sea tides, which can affect their safety, efficiency, and sustainability. Africa’s coastline stretches for over 46,000 kilometers, with many countries having extensive coastlines along the Atlantic, Indian, and Mediterranean oceans (African Development Bank, 2019). The continent’s ports handle a significant proportion of global trade, with many countries relying heavily on maritime transport for the import and export of goods. Sea tides have significant implications for African ports, affecting their safety, operational efficiency, and environmental sustainability. Sea tides can pose safety risks to ships, crew, and port infrastructure. For example, high tides can cause ships to collide with quay walls or other vessels, while low tides can expose hidden obstacles or shallow waters (IMO, 2019). Tides can affect the operational efficiency of African ports by influencing the time and manner in which ships can enter or leave the port. For instance, high tides can limit the draft of ships, while low tides can restrict the accessibility of certain berths (UNCTAD, 2019), Sea tides can also have environmental implications for African ports, such as increased erosion, sedimentation, and water pollution. For example, high tides can cause flooding in nearby coastal areas, while low tides can expose sensitive habitats (IPCC, 2019).

 The coastal regions of West Africa, including countries such as Nigeria, Ghana, and Senegal, are particularly vulnerable to the impacts of sea tides. High tides can cause flooding in coastal areas, while low tides can expose hidden obstacles or shallow waters (African Development Bank, 2019), The coastal regions of East Africa, including countries such as Kenya, Tanzania, and Mozambique, are also vulnerable to the impacts of sea tides. Tides can affect the operational efficiency of ports, such as the Port of Mombasa in Kenya, by influencing the time and manner in which ships can enter or leave the port (UNCTAD, 2019), The coastal regions of Southern Africa, including countries such as South Africa, Namibia, and Angola, are also affected by the impacts of sea tides. For example, high tides can cause erosion in coastal areas, while low tides can expose sensitive habitats (IPCC, 2019). Sea tides have significant implications for African ports, affecting their safety, operational efficiency, and environmental sustainability. The impacts of sea tides vary by region, with different countries facing unique challenges and opportunities. As the global port community continues to address the challenges posed by sea tides, it is essential to prioritize collaboration, innovation, and sustainability to ensure the long-term resilience and competitiveness of African ports.

Cameroon is a Central African country with a coastline along the Gulf of Guinea. The country’s coastal regions are home to several important ports, including the Port of Douala and the Port of Kribi. These ports play a critical role in facilitating international trade and economic development in Cameroon. However, they are also vulnerable to the impacts of sea tides, which can affect their safety, efficiency, and sustainability. Cameroon’s coastline stretches for approximately 400 kilometers along the Gulf of Guinea. The country’s ports handle a significant proportion of the country’s international trade, with the Port of Douala being the largest and busiest port in the country (Cameroon Ports Authority, 2020). Sea tides can pose safety risks to ships, crew, and port infrastructure. For example, high tides can cause ships to collide with quay walls or other vessel Geographical scope: The study is limited to the Douala Sea Port in Cameroon and does not consider other ports in the region. The study collects data over a period of one-year, Low tides can expose hidden obstacles or shallow waters (IMO, 2019). As per the Operational Efficiency, tides can affect the operational efficiency by influencing the time and manner in which ships can enter or leave the port. For instance, high tides can limit the draft of ships, while low tides can restrict the accessibility of certain berths (UNCTAD, 2019). Sea tides can also have environmental implications for Cameroonian ports, such as increased erosion, sedimentation, and water pollution. For example, high tides can cause flooding in nearby coastal areas, while low tides can expose sensitive habitats (IPCC, 2019).

The Littoral Region, where the Port of Douala is located, is particularly vulnerable to the impacts of sea tides. High tides can cause flooding in coastal areas, while low tides can expose hidden obstacles or shallow waters (Cameroon Ports Authority, 2020). The South Region, where the Port of Kribi is located, is also affected by the impacts of sea tides. Tides can affect the operational efficiency of the port by influencing the time and manner in which ships can enter or leave the port (UNCTAD, 2019) The Port of Douala is the largest and busiest port in Cameroon, located in the Littoral Region of the country. The port plays a critical role in facilitating international trade and economic development in Cameroon, as well as in the Central Africa. The history of the port of Douala, was established in 1907 by the German colonial administration, and it has since undergone several expansions and modernizations. In the 1960s, the port was expanded to accommodate larger vessels, and in the 1980s, a new container terminal was built. The infrastructure of the port of Douala has a total area of approximately 200 hectares, with a quay length of 2,500 meters.

 The port has 12 berths, including 4 container berths, 2 oil berths, and 6 general cargo berths. The port also has a range of facilities, including warehouses, cranes, and tugboats. The Port of Douala operated as a multipurpose port, handling a wide range of cargo, including containers, oil, timber, and general cargo. The port is open 24 hours a day, 7 days a week, and it has a team of experienced staff and modern equipment to ensure efficient and safe operations. The Port of Douala is a critical component of Cameroon’s economy, but it faces several challenges, including congestion, infrastructure limitations, and corruption. The port is also vulnerable to the impacts of sea tides, which can affect its safety, operational efficiency, and environmental sustainability. Addressing these challenges and mitigating the impacts of sea tides will be essential to ensuring the long-term resilience and competitiveness of the Port of Douala. (Cameroon port authority 2020) Sea tides have significant implications for Cameroonian ports, affecting their safety, operational efficiency, and environmental sustainability. The impacts of sea tides vary by region, with different ports facing unique challenges and opportunities. As the global port community continues to address the challenges posed by sea tides, it is essential to prioritize collaboration, innovation, and sustainability to ensure the long-term resilience and competitiveness of Cameroonian ports.

1.2 Statement of the Research Problem

The Port of Douala, Cameroon’s largest and busiest port, is facing significant challenges in its operations due to the impacts of sea tides. Despite its critical role in facilitating international trade and economic development in Cameroon, the port’s performance is being compromised by the increasing frequency and severity of sea tides. The resulting flooding, erosion, and disruption of operations are not only affecting the port’s efficiency and safety but also having negative impacts on the environment and local communities. Therefore, this research seeks to investigate the implications of sea tides at berth on the performance of the Port of Douala, with a view to identifying strategies for mitigating these impacts and ensuring the long-term sustainability of the port.
