The ONE Apus Accident: Carrier and Consignees Awaiting Final Resolution

Imagine dispatching a vital shipment of high-value goods across the Pacific, only to learn that nearly 2,000 containers have been lost overboard in a sudden storm, leaving your supply chain in limbo for years. This nightmare became reality for countless shippers and consignees following the ONE Apus accident on November 30–December 1, 2020. As logistics professionals in Hong Kong, we understand the profound frustration of protracted claims processes, uncertain insurance recoveries, and the ongoing wait for closure that persists even into 2026. In this detailed analysis, we dissect the incident, its causes, impacts, and enduring lessons for sea freight operations.

Key Takeaways from This Post

• Gain insights into the largest container losses in history and how the ONE Apus incident ranks among them.
• Understand the technical causes, from parametric rolling to lashing failures, to better secure your cargo.
• Learn proactive strategies to mitigate risks, protect against claims delays, and ensure resilient supply chains.

This table highlights the scale of the ONE Apus accident, second only to the MOL Comfort in terms of containers lost, underscoring the vulnerabilities in ultra-large container vessel (ULCV) operations.

Incident Overview: What Happened Aboard ONE Apus

The ONE Apus, a 14,000 TEU Japan-flagged containership operated by Ocean Network Express (ONE), was en route from Yantian, China, to Long Beach, California, when disaster struck approximately 1,600 nautical miles northwest of Hawaii. Between November 30 and December 1, 2020, the vessel encountered severe weather conditions, resulting in the loss of 1,816 to 1,841 containers overboard, including 64 carrying dangerous goods. Additionally, around 983 to 1,000 deck containers out of 3,593 were damaged due to stack collapses, totaling nearly 2,800 affected containers or about 4,500 TEU equivalent.

Following the incident, the vessel diverted to Kobe, Japan, arriving on December 8, 2020. Over the subsequent weeks and months, approximately 1,000 damaged containers were discharged for inspection and handling. The ship did not resume its original voyage until March 16, 2021, imposing significant delays on consignees who were left waiting for cargo release and damage assessments.

From our experience supporting clients in high-volume sea freight routes across Asia-Pacific, such events expose the fragility of global trade lanes. We have seen similar disruptions amplify costs and timelines, but the ONE Apus case stands out for its sheer magnitude and the prolonged uncertainty it created for all parties involved.

Root Causes: Insights from the JTSB Investigation

The Japan Transport Safety Board (JTSB) released its final report (MA2024-02) on February 29, 2024, providing a meticulous analysis of the probable causes. Severe rolling motions, reaching up to 25–27 degrees, were triggered by 5–6 meter northwest to north-northwest swells. This led to parametric rolling—a phenomenon where a vessel's natural rolling period aligns with wave encounters, amplifying motions beyond securing device limits.

Key findings included:

• No issues with the hull, engines, or overall vessel condition.
• Cargo lashing adhered to the approved program and manual, with checks and retightenings every three days.
• Initial collapses caused secondary failures, resulting in bent lashing bars, deformed containers, and overboard losses.
• Hull damage encompassed bent deck fittings, fractured hatch covers, pipe disruptions, and abrasions from container impacts.

Weather conditions were cloudy with winds of 5.5–7.9 m/s and good visibility—not extreme by Pacific standards, yet sufficient to overwhelm deck stacks on this ULCV. Importantly, no crew casualties occurred, but the report emphasized safety enhancements rather than liability attributions.

In our advisory role for sea freight clients, we stress that while weather is unpredictable, proactive lashing reinforcements and weather routing can mitigate such risks. The incident propelled the International Maritime Organization (IMO) to mandate lost-container reporting, effective around 2023, reflecting broader industry adaptations.

Carrier Response and Operational Fallout

Ocean Network Express managed the crisis by diverting to Kobe for extensive unloading and storage, incurring substantial costs. No immediate General Average (GA) declaration was made, though it was anticipated initially. GA, a maritime principle requiring shared losses among stakeholders, could have compelled consignees to contribute to recovery expenses.

Resuming voyage after months highlighted the operational strain on carriers. High costs for unloading, storage, and reloading underscored the financial burdens of such incidents. For carriers navigating busy transpacific lanes, these events demand robust contingency planning.

At FreightAmigo, our Sea Freight solutions provide economical high-volume options with integrated risk assessments, enabling clients to select vessels and routes with proven stability records.

Consignee Challenges: Delays, Claims, and Uncertainty

Consignees faced delays exceeding one month, with some cargo deemed unrecoverable. Insured parties prioritized recoveries through underwriters, while uninsured shippers risked GA contributions and port fees. As of late 2020, no clear timelines emerged for final goods receipt or claims settlements.

Estimated losses ranged from $90 million to over $200 million, averaging $50,000 per container, constrained by Hague-Visby Rules limits tied to vessel value. Cargo insurance played a pivotal role, with underwriters subrogating claims against vessel interests.

We empathize with consignees enduring this limbo; our platform equips you with Cargo Insurance to safeguard against loss, damage, and transport risks, streamlining claims and providing peace of mind on volatile routes.

Litigation and Insurance Landscape

Legal proceedings consolidated into Multidistrict Litigation (MDL) No. 3028 in the U.S. District Court for the Southern District of New York in June 2022, under Judge Paul A. Engelmayer. Involving 49 actions plus nine related cases, it pitted NVOCCs, shippers, and consignees against the vessel's Japan-based owner, Panama bareboat charterer, and South Korea operator.

Focus areas included causation and liability, with alternative service on foreign entities ordered in 2022. Reports from 2021 noted claims piling up, including notable cargo like Crocs footwear, but no public resolutions or settlements have surfaced through 2026. Trade publications hinted at nearing settlements years ago, yet marine disputes often drag on for multi-party complexities.

This protracted process illustrates why comprehensive insurance and real-time visibility are non-negotiable. Our Track & Trace service offers end-to-end shipment visibility, allowing early detection of risks before they escalate into losses.

Industry Lessons and Preventive Measures

The ONE Apus accident illuminated risks in ULCV operations: weather-induced parametric rolling, deck stack vulnerabilities, and lashing limitations. It spurred advancements like enhanced reporting and weather-optimized routing.

Preventive strategies we recommend include:

• Reinforced lashing protocols beyond standard manuals.
• Dynamic weather routing using advanced forecasting.
• Insurance coverage tailored to high-risk Pacific trades.
• Real-time monitoring via IoT-enabled Track & Trace.

Furthermore, diversifying modes—combining sea with rail or air—builds resilience. Clients using our Sea Freight platform benefit from sailing schedules up to eight weeks ahead, aiding informed decisions.

This table summarizes actionable mitigations drawn from the JTSB findings.

Current Status in 2026: Still No Final Word

As of April 2026, no public announcements confirm full claims resolutions, payouts, or GA finalizations. Litigation remains drawn out, typical for international marine disputes. Carriers and consignees continue navigating uncertainties, with processes rooted in 2020–2024 records showing no closure.

For businesses reliant on transpacific sea freight, this underscores the need for forward-looking tools. Our Duties & Taxes Calculator and Customs Clearance services ensure compliance, reducing secondary delays in recovery scenarios.
