Most Common Types of Accidents in Maritime Container Transport and Prevention
Maritime container transport is the backbone of global trade. According to the latest data from the International Maritime Organization (IMO), over 90% of goods worldwide are transported by sea, with container ships forming the core of this system. In 2023 alone, more than 180 million TEU (Twenty-foot Equivalent Unit = 20-foot container) were transported across the world’s oceans. Modern container ships carry up to 24,000 TEU at once, making them among the largest moving objects ever created by humans.
Although the number of accidents has declined in recent decades thanks to technological development and safety protocols (source: Allianz Safety & Shipping Review 2023, IMO), the consequences of accidents are often catastrophic:
- Loss of life (e.g., fires and explosions on board the X-Press Pearl in 2021).
- Massive economic damage (the Ever Given case in the Suez Canal caused losses in the billions of dollars).
- Permanent environmental impacts (oil spills, loss of containers containing hazardous materials, etc.).
Understanding the causes and typology of accidents, prevention mechanisms, and proper implementation of safety measures is crucial not only for shipowners and crews, but also for cargo owners, insurers, government authorities, and all participants in the logistics chain. This dictionary offers a detailed look at the most common incidents in maritime container transport, their causes, and modern prevention methods.

Allision
What It Is
Allision is a type of accident where a vessel collides with a stationary object (pier, crane, bridge pillar, oil platform, anchored vessel). The key difference from collision is that at least one of the parties is at rest. Typical examples include:
- Impacts on port piers during maneuvering (often caused by poor assessment of speed/course).
- Collisions with coastal cranes (e.g., due to extreme weather conditions).
- Impacts on bridge pillars (e.g., the Francis Scott Key Bridge collapse case in Baltimore 2024).
Significance and Causes
Allision can take critical infrastructure (port, bridge) out of service for weeks to months. For the ship, it means the risk of hull perforation, flooding, fire, or fuel leak. The most common causes:
- Human error during maneuvering in confined spaces.
- Technical failure (e.g., rudder, engine).
- Insufficient communication between captain, pilot, and tugboats.
- Inadequate crew training or fatigue.
- Extreme weather (strong wind, currents).
- Lack of information about current port situation (e.g., AIS outage).
Prevention
- Modern navigation technology (GPS, AIS, ECDIS, ARPA).
- Assistance of experienced pilots and tugboats during maneuvers.
- Regular maintenance and testing of propulsion and control systems.
- Careful planning of port operations (including simulations).
- Extended crew training on crisis situations.
- Real-time monitoring of weather and port conditions.
Safety Protocols
What It Is
Safety protocols are a set of rules, procedures, and measures that regulate ship operations with the aim of minimizing the risk of accidents. They are anchored in international agreements and standards, such as:
- ISM Code (International Safety Management Code) – mandatory for all commercial ships over 500 GT.
- SOLAS (Safety of Life at Sea) – regulations for ship construction, equipment, and operation.
- IMDG Code – rules for the transport of dangerous goods.
Significance and Content
- Emergency procedures: Plans for fire, explosion, DG leak, ship abandonment, man overboard rescue.
- Operating procedures: Safe loading/unloading, work in confined spaces, DG handling.
- Maintenance and inspection: Plans for regular checks of engines, fire-fighting equipment, containers, rescue equipment.
- Training and exercises: Regular drills and crew training on all crisis scenarios.
Prevention
- Implementation of protocols into daily practice – mere existence on paper is not enough.
- Strict enforcement and control (audits, third-party inspections).
- Support for safety culture – safety takes precedence over commercial interests.
- Regular review and update of protocols based on new findings and incidents.
Collision
What It Is
Collision is a collision of two moving vessels, often with fatal consequences. Most common in areas with heavy traffic, poor visibility (fog, rain), or communication/navigation failure.
Significance and Causes
- Loss of life (e.g., BC Ferry Queen of the North, 2006 – 2 dead).
- Environmental damage (fuel leak, DG loss).
- Financial losses (ship damage, cargo delays, fines).
- Causes:
- Non-compliance with COLREGs (International Regulations for Preventing Collisions at Sea).
- Human error (inattention, fatigue, poor decisions).
- Equipment failure (radar, AIS, autopilot).
- Poor communication between vessels (language barrier, radio noise).
- Adverse weather.
Prevention
- Strict compliance with COLREGs.
- Modern technology (radar with ARPA, AIS, ECDIS).
- Simulation training and regular exercises for navigators.
- Multilingual communication on the bridge.
- Real-time monitoring of ship traffic (VTS – Vessel Traffic Service).
Human Error
What It Is
Human error is the most common cause of maritime accidents (up to 80%, source: Allianz). It is not just individual failure, but a complex problem involving:
- Inadequate training, poor shift planning, fatigue.
- Errors in technology design (e.g., complicated navigation interface).
- Poor corporate culture (pressure for speed over safety).
- Stress, isolation, language barriers.
Significance in Container Transport
- Navigation errors (collision, grounding).
- Poor container securing (cargo loss, damage).
- Neglected maintenance (equipment failure).
- Errors in DG handling (fires, explosions).
Prevention
- Holistic approach: ergonomics, training, crew well-being support.
- Robust safety protocols and their enforcement.
- Quality, frequent, and repeated training.
- Monitoring of work load and shift planning with regard to fatigue.
Loading and Unloading
What It Is
The process of moving containers between ship and terminal. It involves the use of giant cranes (STS), automated vehicles, and handling techniques.
Significance and Risks
- Container drop: crane failure, twistlock failure, operator error.
- Improper stowage: leads to ship instability, risk of capsizing.
- Container damage: denting, perforation, contamination.
- Personnel injury: falling objects, equipment accidents, falls from height.
Prevention
- Stowage planning (stowage planning software), automation.
- Regular inspection of cranes, twistlocks, lifting equipment.
- Operator training, compliance with safety zones, use of PPE.
- Inspection of container integrity before loading.
Hazardous Materials
What It Is
Substances that by their nature (flammability, toxicity, explosiveness, radioactivity, corrosiveness) pose a risk to health, safety, and environment. Transport is governed by strict IMDG Code rules.
Significance and Risks
- Improper declaration: main cause of fires and explosions on ships (e.g., Maersk Honam 2018).
- Poor packing/labeling: DG leak, contamination, contact with incompatible substances.
- Chemical reactions: generation of toxic/explosive gases.
Prevention
- Strict compliance with IMDG Code (classification, packing, labeling, documentation, separate storage).
- Systems for documentation control and DG stowage planning on ship (separation from living quarters and other DG).
- Special crew training (chemical fire fighting, leak response).
- Regular audits and inspections of DG shipments.
Container Damage
What It Is
Any disruption of structural integrity or functionality of a container – visible (holes, dents, rust) or hidden (corrosion, seal damage).
Significance and Types
- Structural damage: perforation, deformation, cracks, often during handling.
- Corrosion: long-term exposure to sea air and moisture.
- Door/lock damage: threatens cargo security (theft, contamination).
- Contamination: cargo residue, chemical leak, biological contamination.
Prevention
- Regular inspection (automated gates with OCR and AI).
- Immediate repair of identified defects.
- Use of quality and certified containers (ISO, CSC).
- Careful handling during loading/unloading and transport.
Foundering / Sinking
What It Is
Sinking is the complete loss of buoyancy and submersion of the ship below the surface – the most serious type of accident.
Significance and Causes
- Loss of ship, cargo, and lives.
- Environmental catastrophe (fuel/DG leak).
- Most common causes:
- Extreme weather (storms, waves, cargo shift).
- Collision/allision (hull perforation).
- Fire/explosion (structural weakening, flooding during extinguishing).
- Structural failure (material fatigue, poor maintenance).
Prevention
- Robust ship construction and maintenance (regular inspections by classification societies).
- Use of systems for real-time monitoring of stability and flooding.
- Effective emergency plans and trained crew.
- Route planning away from extreme weather areas (use of meteorological models).
Capsizing / Listing
What It Is
Capsizing – the ship turns on its side or upside down. Listing is dangerous tilting to one side, which can lead to capsizing.
Significance and Causes
- Rapid progression, minimal time for evacuation.
- Most common causes:
- Improper cargo distribution (heavy containers on top).
- Free surface effect (water movement in tanks/deck).
- Extreme weather (waves, wind).
- Sharp maneuvers.
Prevention
- Software for real-time stability calculation.
- Stowage planning (container stowage).
- Ballast operation control.
- Monitoring of cargo and fuel movement during voyage.

Twistlock and Corner Castings
Twistlocks and corner castings are much more than simple metal components—they are the foundation upon which modern global commerce is built. Their standardized design, proven reliability, and continuous development have made them essential to the shipping industry. Understanding how they work, what types are available, and the importance of proper installation and maintenance is essential for anyone involved in container operations. Whether you manage a fleet, operate a port, or simply ship goods internationally, the humble twistlock deserves recognition as one of the most important innovations in the history of logistics.
Moisture from Cargo in Shipping Containers
Cargo moisture in shipping containers refers to the water vapor and liquid moisture present in a closed shipping container that originates directly from the cargo itself, packaging materials, pallets, and ambient air during loading and transportation. Unlike external water from rain or seawater, cargo moisture is an inherent source of moisture that becomes problematic when temperature and humidity fluctuations cause condensation on the surface of the container and cargo.
The Pallet Wide Shipping Container Can Hold Up to 30% More Pallets
A Pallet Wide (PW) shipping container is a specially designed shipping container designed to carry a larger number of European pallets than standard containers. These containers feature an internal width of approximately 2.438 meters (8 feet), which is approximately 9 centimeters more than standard ISO containers.
How do weather and climate conditions affect temperature and humidity in shipping containers?
Container rain, often called “container sweating” or “container rain,” is a critical phenomenon in global shipping, costing the international supply chain an estimated $6-8 billion annually.
