FLEET CAPACITY
Growing with scale, flexibility, and quality.
Seaspan boasts the industry’s largest owned and operated chartered containership fleet, consisting of 218 vessels and approximately 2,300,000 TEU capacity, on a fully delivered basis. Our track record of investing in our fleet through an ambitious newbuild program, coupled with our SAVER vessel series and ongoing modifications and retrofits, demonstrates our commitment to enhancing efficiency, loadability, performance, and safety.
Seaspan has one of the youngest fleets globally, with 70 state-of-the-art vessels joining its fleet between 2021 and 2024, and dozens more on order. Our newbuild vessels are equipped with the latest technological advancements and are more efficient in terms of fuel consumption and maintenance. These modern ships are designed to optimize cargo space and efficiency, resulting in increased loadability and lower operating costs.
FUEL TRANSITIONING
Investing in alternative fuels for the future.
Seaspan is also leading the industry in the transition to cleaner-burning alternative fuels, including LNG, methanol, and ammonia.
This proactive approach aligns with our customer’s decarbonization goals and global efforts toward a greener, more sustainable shipping industry.
By 2029, approximately 25% of Seaspan’s TEU capacity will run on alternative fuels.
INNOVATION & DECARBONIZATION
Charting a course to emissions reduction.
Seaspan’s journey to decarbonize is not about a single event or cost but many actions over time—all framed and aligned around a common strategy and goal.
We are an industry leader in developing modern and efficient vessels and fuel solutions, leveraging technology and innovative ideas to accelerate the transition to a greener shipping industry.
Our team collaborates with customers, technology partners, innovation incubators and leading shipbuilders to invest in cutting-edge research and development of low and zero-carbon technologies. Our approach includes implementing retrofits, transitioning to alternative fuels, enhancing ship design, performance monitoring, regulatory reporting, and more, to achieve our decarbonization goals and assist our customers in achieving theirs.
Energy Efficiency Upgrades
The best way to save fuel and reduce emissions is not to burn it. In this regard, Seaspan pays particular attention to the overall efficiency of its vessels, meaning maximizing cargo loadability and reducing fuel consumption, often referred to as our SAVER initiative. Seaspan offers a wide range of cargo loadability, machinery, and hydrodynamic upgrades.
Radical Derating of Large Bore Engines
Seaspan is working with partners to develop a solution for the radical derating of large-bore main engines. This groundbreaking retrofit solution will reduce the bore size of engine cylinders by 25%, enhancing combustion efficiency and significantly lowering fuel consumption and greenhouse gas emissions. With a new, optimized combustion chamber design, the modified vessels will run at optimal loads with state-of-the-art fuel efficiency.
Designing an Ammonia-Fueled Container Vessel
To help our customers achieve their decarbonization goals, Seaspan has partnered with the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping to develop a concept design for a 15,000 TEU ammonia-powered container vessel. Developing an ammonia-fueled vessel is a key step in decarbonizing the maritime sector.
Fuel Conversion Retrofits
Methanol and LNG Conversions
Seaspan is working to retrofit a series of vessels for conversion from conventional S90 engines to dual fuel engines capable of running on methanol. Each conversion can provide a CO2 reduction of 50,000 –70,000 tonnes each year when operating on green methanol.
Beyond the current methanol conversion retrofits Seaspan is currently executing, we also offer LNG vessel conversions. Retrofitting is a necessary component of emissions abatement, and is an effective way to deliver fuel flexibility to our customers.
Next Generation Feeder Ship
Lloyd’s Register has awarded Approvals in Principle to Seaspan for its innovative Next Generation Feeder Ship Design for LNG and ammonia vessels.
Through working with partners in innovation, we have developed a solution to meet future market decarbonization demands and have laid the groundwork for future advancements in ammonia-powered feeder vessel technology.
