A converted tanker, Ideal X, sailed from Port Newark, New Jersey, to Houston carrying truck bodies that functioned as early containers. This showed that putting goods into standardized boxes could cut handling time and damage compared with traditional “break-bulk” loading of individual items. The idea became a foundation for the modern global container shipping network.
ISO 668 was introduced to classify and standardize key container dimensions and ratings for “Series 1” freight containers. Standard sizes made it easier for shipping lines, ports, railroads, and trucking firms to build compatible equipment (ships, cranes, railcars, and chassis). This technical change helped container shipping scale globally.
Mediterranean Shipping Company (MSC) was founded in 1970 by Gianluigi Aponte and Rafaela Aponte-Diamant. The company began with the purchase of its first ship, Patricia, and initially operated services linking the Mediterranean with East Africa. Over time, MSC expanded from small beginnings into one of the world’s largest container carriers.
Maersk’s large-scale move into containerization accelerated when Adrian Mærsk departed Port Elizabeth, New Jersey, on a fully containerized service. This step reflected how major established shipping firms were reorganizing fleets and routes around containers rather than mixed cargo methods. It helped expand reliable scheduled container links supporting global supply chains.
Jacques Saadé founded Compagnie Maritime d’Affrètement (CMA) on September 13, 1978, starting with a small team and an initial Marseille–Beirut service. CMA’s early focus was regional liner shipping (regular, scheduled routes) in the Mediterranean. This company later became the core of what would grow into CMA CGM, a major global container line.
In 1996, France’s state-owned Compagnie Générale Maritime (CGM) was privatized and sold to CMA. This purchase created the combined CMA CGM organization and moved the company from a regional carrier toward a larger global role. Consolidation like this was a key trend as container shipping firms grew to serve worldwide supply chains.
A.P. Moller (parent of Maersk Line) agreed to buy Sea-Land’s international liner shipping business in a major industry deal. The purchase included ships, containers, and terminal assets, increasing Maersk’s scale and network reach. These types of acquisitions helped a few very large carriers serve more trade lanes with bigger fleets and shared infrastructure.
CMA CGM acquired Delmas, a French carrier with strong Africa-related trade links, strengthening CMA CGM’s presence in key routes. This continued a broader industry shift toward fewer, larger carriers with wider geographic coverage. Greater route coverage supported the growth of global supply chains by offering more direct and frequent services.
Maersk, MSC, and CMA CGM announced plans for the “P3 Network,” a long-term vessel-sharing arrangement on major East–West routes. In June 2014, China’s Ministry of Commerce (MOFCOM) did not approve it, and the partners stopped the project. The episode showed how government competition reviews can shape the structure of global container networks.
After P3 ended, MSC and Maersk signed a 10-year vessel-sharing agreement covering the three main East–West trade lanes (Asia–Europe, Trans-Pacific, and Trans-Atlantic). Known as “2M,” it focused on operational cooperation—sharing ships and slots—rather than joint pricing or sales. This kind of alliance became a central way carriers improved coverage and efficiency without full mergers.
CMA CGM, COSCO, Evergreen, and OOCL announced plans to form the “Ocean Alliance,” aiming to coordinate vessel deployment and port rotations across major routes. The alliance model helped carriers offer more sailings and broader port coverage without each company operating a complete standalone network. It also signaled the industry’s move toward large, stable operating partnerships.
A new global limit on sulfur content in ship fuel oil took effect, commonly called “IMO 2020.” The rule reduced the cap outside designated emission control areas to 0.50% (from 3.5%), pushing carriers to change fuel use and operations. Compliance added costs and planning needs, showing how environmental regulation can reshape global shipping economics.
UNCTAD’s Review of Maritime Transport 2020 described how the COVID-19 pandemic disrupted trade and shipping operations and pressured maritime transport demand. It highlighted the sector’s role in keeping essential goods moving, while also facing health restrictions and supply-chain disruptions. By 2020, these stresses made container shipping reliability and resilience a major policy and business focus.
