What Seaspan Corporation does

Seaspan Corporation is the world's largest independent maritime asset owner and operator, providing long-term fixed-rate vessel leases and integrated ship management services to major global shipping lines and automotive logistics customers. The company operates a fleet of approximately 247 vessels (as of March 2026, pro forma newbuilds) with roughly 2.5 million TEU capacity, including dual-fuel LNG, methanol-ready, and ammonia-ready container vessels, dual-fuel LNG Pure Car and Truck Carriers (PCTCs), Very Large Ethane Carriers (VLECs), and Open Hatch Gantry Crane vessels. Core technology assets include the proprietary SAVER (Seaspan Action on Vessel Energy Reduction) vessel designs and retrofit program (552 upgrades across 86 vessels, $226.5M invested), dual-fuel propulsion systems, and a digital fleet layer comprising third-party AI navigation (Avikus), IoT sensor platforms (Raa Labs), cloud-based chartering and emissions SaaS (Ankeri), and Starlink/OneWeb LEO connectivity.

Seaspan generates revenue primarily through multi-year fixed-rate charter agreements with global container liner operators including ONE, MSC, Maersk, CMA CGM, COSCO, Hapag-Lloyd, ZIM, Yang Ming, and Evergreen. A secondary revenue stream comes from integrated ship management services covering technical management, crew management, commercial management, and procurement through the Sea Sourcing joint venture (with Anglo-Eastern, covering 800+ vessels) and the ONESEA Solutions joint venture (with ONE). The company is a privately held wholly-owned subsidiary of Atlas Corp (NYSE: ATCO), with its primary corporate headquarters in Singapore and registered address at Seaspan Corporation Pte. Ltd., operating regional offices in Hong Kong, Mumbai, Vancouver, Denmark, Germany, France, Shanghai, and Taiwan.

Strategically, Seaspan is positioning for maritime decarbonization through methanol retrofits (Project SAVER CleanBlue with Hapag-Lloyd), LNG dual-fuel newbuilds, ammonia-powered feeder vessel designs (with Lloyd's Register AiP), SMR nuclear-propulsion research, and a target of 25% of TEU capacity running on alternative fuels by 2029. Recent equity developments include Ocean Network Express (ONE) increasing its stake in Poseidon Corp to 48.9%, Yangzijiang Shipbuilding acquiring a 10% stake for US$825.7 million, and Fairfax Financial retaining approximately 22% after partial monetization. Adjusted EBITDA has grown over 50% since 2021 to exceed US$1.8 billion, and S&P upgraded the credit rating from BB- to BB in December 2025.
