What Does Ship By Sea Mean?

  • by

“Ship by sea” is a phrase that is frequently used in the fields of logistics and transportation. It refers to delivering items or cargo over bodies of water, such as oceans, seas, rivers, or canals, using maritime boats. Over several centuries, this mode of transportation has been a vital component of international commerce.

It provides an efficient and economical method for transporting vast quantities of products between countries and continents. In this article, we will delve into the complexities of shipping by sea, discussing its benefits, difficulties, and the role it plays in the contemporary economy of the entire world.

What Does Ship By Sea Mean?

When commodities or cargo are transported by ships across bodies of water, such as oceans, seas, rivers, or canals, the term “ship by sea” refers to how this is accomplished. It is a common mode of transportation for international trade, and it provides a means that is both efficient and cost-effective for moving vast amounts of commodities between countries and continents.

Over several centuries, this mode of transportation has been an indispensable component of international trade, and it continues to be an important component of the contemporary economy.

Here are some more examples of what “shipping by sea” entails:

  • Exporting automobiles manufactured in Japan to various destinations around the world by loading them onto cargo ships and transporting them across oceans.
  • Importing raw materials like crude oil from oil-producing countries in the Middle East to refineries located in other parts of the world via tanker ships.
  • Sending large machinery and equipment, such as wind turbines or industrial boilers, from manufacturing facilities in one country to construction sites or factories in another country by sea freight.
  • Shipping perishable goods like fruits and vegetables from agricultural regions to distant markets using refrigerated containers on container ships.
  • Transporting consumer goods, electronics, clothing, and other products manufactured in countries like China to retail markets in Europe, North America, or other regions via container ships.
  • Exporting bulk commodities like grain, coal, iron ore, and minerals from resource-rich countries to global markets by loading them onto bulk carriers for sea transport.

These examples illustrate the diverse range of goods and commodities that are transported by sea, highlighting the importance of maritime shipping in facilitating global trade and commerce.

How Long Is Shipping By Sea?

The duration of shipping by sea can vary widely depending on several factors:

  • Distance: Naturally, the farther the destination, the longer the shipping time. Shipping from one continent to another typically takes longer than shipping within the same continent.
  • Route: Some shipping routes are more direct and efficient, resulting in shorter transit times, while others may involve longer routes with multiple stops or detours.
  • Speed of the vessel: The speed at which the vessel travels can impact the duration of the journey. Faster vessels can cover distances more quickly but may come at a higher cost.
  • Weather and sea conditions: Adverse weather conditions such as storms or rough seas can delay voyages, while favourable conditions can speed up travel times.
  • Port congestion and delays: Congestion at ports, as well as delays in loading and unloading cargo, can prolong the overall shipping time.

Shipping by sea can take anywhere from a few days to several weeks or even months, depending on these factors. For example, a transatlantic voyage between Europe and North America might take around 7 to 14 days, while shipping from Asia to Europe or North America could take 2 to 6 weeks. However, it’s essential to check with shipping companies or logistics providers for specific transit times for your shipment.

Is It Cheaper To Ship By Air Or Sea?

Shipping by sea is typically cheaper than shipping by air for most types of cargo. Here’s why:

  • Cost per unit weight: Sea freight costs are generally lower per unit weight compared to air freight. Ships can carry a large volume of cargo, spreading the cost across many items, whereas aeroplanes have limited space and weight capacity, leading to higher costs per unit.
  • Fuel and operational costs: Ships consume less fuel per ton-mile than aeroplanes, making sea freight more fuel-efficient and cost-effective for transporting large quantities of goods over long distances.
  • Handling charges: Air freight often involves more handling and processing at airports, which can incur additional fees. Sea freight may have fewer handling charges, especially for containerized shipments.
  • Insurance premiums: Insurance premiums for shipping by sea are typically lower than for air freight due to the lower risk of damage or loss during transit.
  • Speed versus cost trade-off: While air freight is much faster than sea freight, the expedited service comes at a significantly higher cost. Businesses often opt for sea freight when they can afford longer transit times in exchange for lower shipping expenses.

However, there are exceptions. For urgent or time-sensitive shipments, air freight may be the preferred option despite the higher cost. Additionally, certain high-value or perishable goods may justify the expense of air shipping to ensure timely delivery and minimize the risk of damage or spoilage.

Ultimately, the choice between shipping by air or sea depends on factors such as budget, transit time requirements, type of cargo, and specific logistical needs.

How Much Is Shipped By Sea?

Shipping goods around the world via sea accounts for a sizable chunk of the overall value of all trade. There are items worth trillions of dollars that are transported each year by water, according to statistics from groups like the International Maritime Organisation (IMO) and the United Nations Conference on Trade and Development (UNCTAD).

Variations in economic circumstances, global trade patterns, and other factors might cause exact data to fluctuate from one year to the next. The rising importance of marine transportation in promoting international trade and commerce has been reflected in the constantly increasing value of products moved by water in recent years.

Verified sources specialising in marine trade and logistics, such as the International Marine Organisation (IMO), the United Nations Conference on Trade and Development (UNCTAD), or similar organisations, give accurate and current figures on the value of commodities moved by sea. Data and analysis on shipping patterns worldwide, including the value of products transported by sea, are usually available from these sources.


Trade and business on a worldwide scale rely on shipping by water, which enables the conveyance of various goods and commodities via rivers, canals, and oceans. The capacity to transport huge or heavy things at a low cost, as well as access to landlocked or distant places through networked rivers, are all benefits of this mode of transportation.

Sea transport has always been essential in bridging cultural divides and facilitating the worldwide dissemination of ideas, goods, and technology. Manufacturing, agriculture, retail, and construction are just a few of the many modern-day industries that rely on it.

Although sea freight is typically less expensive than air freight, it typically takes more time to deliver. Nevertheless, improvements in infrastructure, logistics management, and technology are constantly making maritime transportation more efficient and dependable, reducing the impact of problems like port congestion, weather delays, and security threats.

The significance of maritime transportation is anticipated to persist in the face of ever-changing global trade patterns, fueling expansion, promoting collaboration among nations, and adding to the interdependence of the global economy.

Companies may improve their supply chains, expand into new markets, and take advantage of chances for long-term growth in today’s globally linked economy by making use of the extensive system of maritime routes and infrastructure.
