Marine shipping is a crucial component of the global economy, responsible for transporting over 90% of the world's goods by volume. This includes everything from electronics and clothing to food and machinery.
The global shipping industry is estimated to be worth over $1 trillion annually, making it one of the largest industries in the world. The industry's size and scope are a testament to its importance in facilitating international trade.
The average container ship carries around 14,000 containers, each measuring 20 feet long and 8 feet wide. This is a staggering amount of cargo, and it's a reminder of the sheer scale of the industry.
The Suez Canal, a critical waterway connecting the Mediterranean Sea to the Red Sea, is used by over 17,000 vessels annually, with an average of 50 ships passing through every day.
Marine Shipping Basics
Marine shipping is a complex process that involves several key components. The first step is to understand the different types of marine shipping, which include container shipping, bulk shipping, and project cargo shipping.

Container shipping is a popular choice for transporting goods, with over 90% of non-bulk cargo transported in containers. Containers are designed to be stackable and can be easily transferred between ships and trucks.
The International Maritime Organization (IMO) sets safety and security standards for marine shipping, including regulations for container safety and security. The IMO also regulates the use of ballast water, which can harm marine ecosystems if not handled properly.
Shipping routes and schedules are critical to the success of marine shipping. The busiest shipping routes include the Strait of Malacca and the Suez Canal, which connect major trade hubs like China and Europe.

In 2015, Canada's international marine trade totalled $205 billion, with $93 billion being exports.
Marine shipping is essential to Canada's prosperity and plays a crucial role in the country's economy.
Canada's international marine trade includes both exports and imports, with $112 billion worth of imports in 2015.
From small independent retailers to global manufacturers, marine shipping is often the only way to get products to markets outside of North America.
Marine Shipping Industry
Marine shipping is a vital part of Canada's economy, allowing Canadians to export their products to the rest of the world. Canadians rely on ships to transport goods to international markets, which is essential to the country's prosperity.
Getting goods to international markets is a complex process, but marine shipping makes it possible. It's a necessity for businesses of all sizes, from small independent retailers to global manufacturers.
Marine shipping is used to transport a wide variety of products, including the top 15 marine export commodities by total value from 2006 to 2015.
Market Outlook
The marine vessels market is expected to reach a significant milestone by 2030, with a projected value of US$133.63 billion.
This growth is largely driven by the increasing demand for efficient transportation of goods, which in turn requires larger and more versatile vessels.
Global trade continues to fuel the demand for different types of ships, and the military navy growth has also been contributing to the expansion of the market.

The strategic fleet renewal remains critical for market improvement, with new and fuel-efficient vessels supporting the transition towards sustainable shipping practices.
Cruise lines are adding more ships to cater to the needs of travelers focusing on unique experiences, which is further driving the demand for fleet expansion and technology upgrades.
The international rules targeting reduced emissions are becoming increasingly important, and the marine vessels market is expected to adapt to these changing standards.
Liners and Tramps
Liners are ships that have a regular run and operate to a schedule, requiring better equipment to deal with potential delays like bad weather. They're generally higher powered than tramp ships with better seakeeping qualities, making them significantly more expensive to build.
One of the key characteristics of liners is their ability to carry a variety of cargo, including passengers, containers, mail, and general cargo. They're built with this versatility in mind.
Liners are often compared to tramp ships, which have no fixed run and go wherever a suitable cargo takes them. A tramp ship might be chartered to fetch a cargo of grain from Canada to Latvia, and then carry a cargo of coal from Britain to Melanesia.

Marine Shipping Careers
A career in marine shipping can be a rewarding and challenging experience. A ship's complement can be divided into four categories: the deck department, the engine department, the steward's department, and other.
The deck department is responsible for the navigation and operation of the ship, including tasks like steering and anchoring. The engine department is in charge of the ship's propulsion systems, including engines and generators.
Here are the four main categories of a ship's complement:
- The deck department
- The engine department
- The steward's department
- Other
Professional Mariners
As a professional in the marine shipping industry, you'll likely be part of a ship's complement, which can be divided into four main categories.

The deck department is one of these categories, responsible for navigating and maintaining the ship's hull and superstructure.
The engine department is another crucial category, handling the ship's propulsion and mechanical systems.
The steward's department is responsible for ensuring the crew's living and working conditions are comfortable and safe.
Finally, there are other categories that don't fit into the above three, including medical staff and security personnel.
Life at Sea
Spending time at sea can be physically demanding, with some cargo ships traveling over 20,000 nautical miles per year.
The crew of a cargo ship typically consists of 15 to 30 people, including officers, engineers, and deckhands.
Officer cadets can expect to work long hours, often exceeding 12 hours a day.
The living quarters on a cargo ship are often cramped, with shared bunks and limited personal space.
Cargo ships have some of the most advanced navigation systems in the world, including GPS and radar.

The galley, or kitchen, on a cargo ship is usually small and simple, with limited cooking facilities.
The crew of a cargo ship must be prepared for emergencies, including fires, floods, and medical emergencies.
Cargo ships often travel through rough seas, with waves reaching heights of over 30 feet.
The crew of a cargo ship must also deal with the physical effects of being at sea, including seasickness and fatigue.
The captain of a cargo ship is responsible for the safety of the vessel, its crew, and its cargo.

Infrastructure
Infrastructure plays a crucial role in marine shipping, and it's not just about having a dock. Docks, bollards, pilings, cranes, and bulk cargo handling equipment are just some of the essential components that support the role of the facilities.
Docks can vary in their capabilities, with some handling intermodal transport needs, such as container-ships linked to rail by cranes, while others are outfitted for bulk handling capabilities, like conveyors, elevators, and tanks for loading and unloading bulk cargoes like grain, coal, or fuels.
A harbor, seaport, or marina typically hosts watercraft and consists of components such as piers, wharfs, docks, and roadsteads.

Innovation and Development
The maritime industry is under pressure to decarbonize, and it's an area where innovation is crucial. Companies like DNV are helping to navigate these complex challenges by providing up-to-date information to turn uncertainty into confidence.
Decarbonizing shipping requires a multifaceted approach, and one key area of focus is reducing greenhouse gas emissions. The International Maritime Organization (IMO) estimates that carbon dioxide emissions from shipping were equal to 2.2% of the global human-made emissions in 2012.
To put this into perspective, consider the impact of shipping on the environment. The environmental impact of shipping includes greenhouse gas emissions, acoustic, and oil pollution.

One potential solution to reduce emissions is to transition to cleaner fuels. The IEA forecasts that ammonia will meet approximately 45% of shipping fuel demands by 2050.
The maritime industry is also exploring alternative modes of transport, such as water transport and freight transport. These options can help reduce emissions and improve efficiency.
Here are some key terms related to marine shipping innovation:
- Maritime transport
- Merchant navy
- Shipping
- Water transport
- Freight transport
