From break bulk to mega vessels<\/strong><\/h2>\n\n\n\nBefore containerisation, cargo was shipped as break bulk\u2014barrels, crates, and sacks manually loaded into ship holds. This method was slow, labour-intensive, and prone to damage and theft. Ships could spend weeks in port, making global trade inefficient and costly.<\/p>\n\n\n\n
In 1956, American trucking entrepreneur Malcolm McLean launched the Ideal-X<\/em><\/a>, the world\u2019s first container vessel, a converted oil tanker that carried just 58 containers. The impact was revolutionary with loading costs dropping from around $6 per ton to just 16 cents. By the 1960s, standardised containers known as a Twenty-foot Equivalent unit (TEUs) and intermodal transport reshaped shipping, improving efficiency, security, and affordability.<\/p>\n\n\n\n![\"\"](\"https:\/\/abl-group.com\/abl\/wp-content\/uploads\/2025\/10\/A-large-ship-in-the-water-AI-generated-content-may-be-incorrect_-1.jpg\")
<\/figure>\n\n\n\nThe 1970s saw the adoption of the container begin to grow with purpose-built fully cellular container ships being built, and ports developing the container cranes to handle them. These vessels such as the Liverpool Bay class carried up to 2,500 TEU.<\/p>\n\n\n\n
Through the 1980s and 1990s, ship sizes were constrained by the dimensions of the Panama Canal, about 32 metres, a design known as Panamax. But with China\u2019s rise as a global exporter, larger vessels became viable. Maersk led the charge with the 8,000+ TEU Sovereign Maersk<\/em> in 1997 and the 14,000+ TEU Emma Maersk<\/em> in 2006. By the mid-2010s, Ultra Large Container Vessels (ULCVs) became the norm, with the Ever Alot<\/em> breaking the 24,000 TEU barrier in 2022.<\/p>\n\n\n\nModern risks and operational challenges<\/strong><\/h2>\n\n\n\nExtreme weather<\/h3>\n\n\n\n
Despite technological advances, container shipping faces persistent risks. Container losses at sea remain a concern, with spikes in recent years due to extreme weather. Diverted routes around the Cape of Good Hope, prompted by Red Sea security threats, increase exposure to rough seas and the likelihood of cargo loss.<\/p>\n\n\n\n
Parametric rolling<\/h3>\n\n\n\n
Parametric rolling\u2014a violent side-to-side motion triggered by specific wave conditions\u2014is particularly dangerous for large container vessels. Though underreported, it can lead to catastrophic outcomes if not properly managed. Enhanced weather routing software and crew training are helping mitigate these risks.<\/p>\n\n\n\n
Cargo securing gear<\/h3>\n\n\n\n
Container securing gear has also evolved, with automatic and semi-automatic twist locks replacing manual systems. However, these can release unintentionally in bad weather as the lifting forces used to release them could be replicated by the vessel\u2019s motion in rough seas.<\/p>\n\n\n\n
Fire<\/h3>\n\n\n\n
Fire risks are rising, often linked to misdeclared dangerous goods. In 2023, container fires occurred every 9 days according to statistics from Cargo Incident Notification System (CINS)<\/a>. Fires also had significant impact in the first six months of 2025 with the Nordic Association of Marine Insurers<\/a> reporting that, of claims above $10 million, nearly 60% were fires, with four of those claims exceeding $20 million.<\/p>\n\n\n\nLithium-ion batteries are a particular concern, with recent incidents off India\u2019s coast resulting in fatalities and massive claims. Fires also cause environmental damage, with firefighting efforts releasing pollutants and microplastics into the sea.<\/p>\n\n\n\n
Ongoing solutions<\/h3>\n\n\n\n
Detection and prevention technologies\u2014such as thermal imaging and hydro-pen systems\u2014are being deployed. Ports are enhancing inspection protocols, and the IMDG Code<\/a> is mandating stricter training and enforcement. AI and blockchain tools are helping flag suspicious cargo bookings, while misdeclaration fees now range from around $15,000\u2013$30,000 per incident.<\/p>\n\n\n\nGeopolitical threats and cyber resilience<\/strong><\/h2>\n\n\n\nGPS jamming is an escalating threat, particularly in regions of geopolitical tension and conflict. It works by overpowering satellite signals with strong radio frequencies, disrupting navigation systems like AIS, GMDSS, autopilot, ECDIS, and radar. This creates a barrage of alarms on the bridge, overwhelming crews and compromising safety.<\/p>\n\n\n\n
In May 2025, the MSC Antonia<\/em> ran aground on a well-charted reef in the Red Sea, an incident linked to GPS jamming. In the Eastern Baltic, crews reported outages in satellite TV and mobile services, halting windfarm operations reliant as their dynamic positioning systems relied heavily on GPS.<\/p>\n\n\n\n\n![\"\"](\"https:\/\/abl-group.com\/abl\/wp-content\/uploads\/2025\/10\/A-large-ship-with-containers-on-it-AI-generated-content-may-be-incorrect_.jpg\")
