Global maritime traffic and the numerous sea routes around the world are both fascinating and important. They not only affect companies engaged in maritime activities but also have an impact on all industries and consumers. These sea routes are used by a wide array of vessels, facilitating the transportation of diverse commodities from cargo owners and producers to their respective customers and consumers. The British economist David Ricardo was among the pioneers to recognize the significance of global trade. In the 1800s, through his studies, he formulated the classical theory of comparative advantage in 1817.
Microsoft’s CoPilot defines global trade as "a dynamic force that connects us, fuels prosperity, and enriches our lives by bridging cultures, economies, and aspirations." Since the dawn of civilization, humans have engaged in trade with one another. Initially, this was limited to neighboring communities. However, as transportation methods improved, allowing for longer distances to be traversed via sea, air, roads, railway tracks, etc., goods and cargoes began to be shipped to all corners of the globe.
Global trade enables consumers and countries to access goods and services that may not be available domestically or are more costly locally, as different countries possess varying assets and natural resources (land, labor, capital, technology). By engaging in global trade, countries can specialize in producing goods more efficiently and distribute them to where they are most needed.
Straits, canals, and narrow waterways play a critical role in global maritime transportation, facilitating significant ship movements each year owing to their strategic locations and economic importance.
Safe navigation and the security of the seas are regulated by the United Nations through the specialized agency IMO (the International Maritime Organization). The United Nations Convention on the Law of the Sea (UNCLOS) has established a global legal framework for maritime traffic, which includes rights to pass through important straits within countries' national territories.
The right for a transit passage is specified in Article 38 of UNCLOS, regulating the most important straits for international maritime traffic:
Although the Kiel Canal stands as the world's busiest artificial waterway, with nearly 30.000 vessels transiting annually, it is not regulated by the UNCLOS laws at Sea.

Let's delve into the distances between the Far East and Europe, as well as the Far East and the US Gulf (USG), and examine the diverse sea route options. These routes present differing sailing distances and associated risks.
Table 1: Distances for different distances
Different types of vessels have varying service speeds, which directly impact the duration of voyages. One of the primary motivations behind the construction of the famous Suez Canal (opened in 1869) and Panama Canal (opened in 1914) by the French was to shorten the distance and reduce the number of days required to transport goods from East to West and vice versa.
Hence, for global maritime traffic, ensuring the accessibility and safety of these maritime straits is of utmost importance. These straits play a critical role in reducing sailing distances between production sites and markets, ultimately facilitating efficient transportation of cargoes and goods.
The closure of certain straits due to wars or anti-shipping activities results in increased transportation costs for bulk cargoes or consumer goods. This is because vessels are forced to navigate longer sailing distances, bypassing these closed straits by traveling around South Africa in open international waters, and/or higher insurance premiums to the heightened risks associated with alternative routes.
South Africa serves as a safe spot or waypoint for vessels sailing from East to West and vice versa, located in international waters and offering a secure passage for maritime traffic.
Here is how the speed influence number of days to perform a sea route:
Table 2: How the speed influence number of days to perform a sea route from Rotterdam to Chiba
Table 3: How the speed influence number of days to perform a sea route from Houston to Chiba
According to historical AIS, the average service speed (from the AIS) for different type of vessels larger than 10 000 dwt during the last 6 months are:

According to Maritime Safety Information there were reported 185 anti-shipping activities in 2023, and in 2022 there were 248. So far in 2024 there have been reported 123 anti shipping activities. Every time an anti-shipping activity is reported, the ship and cargo owners, ship and cargo operators and their brokers, knows their business might be changing.
The people involved in maritime business follow the news and continuously search for information in real-time to be pro-active, mitigate losses and look for opportunities. However, historical information is important to better understand real-time activities and compare these with previous events, helping them make more qualified decisions without taking on too much (new) risk and additional costs.
There are several sea route options to/from the Far East (incl Middle East) to North Europe. In ShipIntel you will find a sea route calculator helping you study different sea route alternatives, showing you nautical miles, time, costs and risks involved, enabling you to quickly find which sea-route you want to plan for your vessels.
The sea route from Aden to Suez to Gibraltar is the most frequently used route from the Far East to Europe and vice versa, while the most popular alternative route is via Cape of Good Hope.
Due to attacks by the Houthi group on vessels in the Bab el-Mandeb Strait (Strait of Aden), maritime traffic is avoiding the commonly used route through the Suez Canal. This avoidance is causing significant losses for Egypt, as revenue from sea passages through the Suez Canal is Egypt’s primary income source. As of January 2023, monthly revenue from the Suez Canal reached 23 billion Egyptian pounds (approximately 743 million U.S. dollars) (Source: CoPilot).
Looking at table 2, sailing around Cape of Good Hope from Chiba to Rotterdam at 15 knots takes an additional 9 days compared to passing through the Suez Canal. Assuming vessels consume 35 mt (metric tons) of fuel per day, this equates to 315 mt for one leg, and over 600 mt for both legs. This results in an increase in carbon emissions of 985 mt (for just one vessel) compared to sailing through the Suez Canal. In 2023, more than 20,000 vessels passed through the Cape of Good Hope.
The graphs below show the selected sea routes for all type of vessels in 2022 and 2023, and in January 2024.
It's evident that the Houthis control of Bab-el-Mandeb Strait, the Israeli war and the Panama Canal facing water shortages due to climate change, numerous vessels, regardless of type, opt to sail around the Cape of Good Hope.
This results in more carbon emissions, higher tax for carbon emissions, higher bunker costs and then higher freight rates.
The graphs above shows number of passages (East/West or North/South) for LPG, Dry cargo, tankers, LNG, Chemicals, Container and car carriers distributed on each month in 2022, 2023 and Jan/Febr 2024.
No, not necessarily. Different types and sizes of vessels may follow different sea routes. Container vessels and dry bulk vessels, for example, have distinct trading patterns. However, they all share a common desire to avoid interference in war and conflicts.
The type of sea route selected by different types of vessels depends on various factors, including war risk, the risk of delays and potential penalties, fees for canal passages, availability and cost of bunker fuel along the sea route, weather forecast, and insurance premiums.
In ShipIntel, users have access to historical trade data as well as real-time AIS data for vessels. This enables users to quickly obtain an overview of any fleet or type of vessels they are interested in. With real-time AIS data, users can track vessel movements as they happen, allowing for up-to-date monitoring of maritime activities. Additionally, users have the option to set up notifications for specific vessels or lists of vessels, ensuring they are informed about any changes in trading patterns as they occur.
