The incident also resulted in damage to a further 62 containers and damage to the ship’s gangway, superstructure and lashing bridges.
The 4,250 TEU vessel was on its way from Kaohsiung, Taiwan to Port Botany in Australia, when it was hit by severe weather conditions on June 1, according to a report by the Australian Transport Safety Bureau (ATSB).
While it was in a position about 16 nautical miles east-south-east of Newcastle, the ship experienced a period of quick, heavy rolling for about 60 to 90 seconds. The rolling was estimated by the ship’s master as having reached angles of up to 30º to port and starboard.
Shortly after the start of the rolling, several engineering alarms sounded and the main engine shut down with the rpm reducing to zero.
The second officer reported hearing loud noises on deck and suspected that there had been some cargo damage. He turned on the ship’s deck lights and observed that containers had been damaged and possibly lost overboard from the bays aft of the accommodation.
Soon after, the main engine was re-started and the engine telegraph on the bridge was placed at ‘dead slow ahead’ and then, almost immediately, placed at ‘stop’ again. The ship continued to drift in the gale force winds and seas for some two hours, when the main engine was started and the ship resumed passage for Port Botany.
In the morning, the ship’s crew conducted more detailed damage assessments and attempted to stabilise the damaged and collapsed containers on deck. The container loss and damage was found to be limited to bays 52 and 56.
Over the next few days, the Australian Maritime Safety Authority (AMSA), along with Roads and Maritime Services, NSW, continued to work with the ship’s owners and insurers to detect, identify and track containers and their contents on the NSW coast.
YM Efficiency eventually berthed in Port Botany on June 6 and over the next days it underwent a number of investigations. On June 11, the first damaged container was discharged and by June 21, all remaining damaged containers had been removed. YM Efficiency departed Port Botany for Melbourne on June 22.
ATSB launched an investigation to analyse the ship’s container stow and lashing arrangement, its stability condition, actions of the ship’s officers and crew following the incident and weather conditions at the time of the incident.
賴瑞比亞國旗的集裝箱船YM Efficiency在船外失去了81個集裝箱，並在烈風天氣條件下遭受結構性破壞。
事件還導致另外62個集裝箱受損，並損壞了船舶的舷梯，上層建築和固定橋。
根據澳大利亞運輸安全局（ATSB）的一份報告，這艘4,250標準箱的船隻正在從台灣高雄前往澳大利亞的波特尼港，當時它在6月1日受到惡劣天氣的影響。
當它位於紐卡斯爾東南偏東約16海裡的位置時，該船經歷了一段快速，重型滾動約60至90秒的時間。船長估計滾動到港口和右舷的角度達到30º。
在軋製開始後不久，幾個工程警報響起，主發動機關閉，轉速降至零。
據報導，副駕駛在甲板上聽到大聲的聲音，並懷疑有一些貨物損壞。他打開船上的甲板燈，觀察到集裝箱已經損壞，可能從船尾後面的海灣淹沒。
不久之後，主發動機重新啟動，橋上的發動機電報被放置在“慢慢前進”，然後幾乎立即再次“停止”。當主發動機啟動並且船停在波特尼港的通道後，這艘船繼續在大風和大海中漂流大約兩個小時。
早上，船員進行了更詳細的損壞評估，並試圖穩定甲板上受損和倒塌的集裝箱。發現容器損失和損壞僅限於52和56之間。
在接下來的幾天裡，澳大利亞海事安全局（AMSA）以及新南威爾士州的道路和海事服務部門繼續與船主和保險公司合作，檢測，識別和跟踪新南威爾士州海岸的集裝箱及其內容。
YM Efficiency最終於6月6日停泊在Port Botany，並在接下來的幾天內進行了多次調查。6月11日，第一個受損的集裝箱卸下，到6月21日，所有剩餘的受損集裝箱已被拆除。YM Efficiency於6月22日離開墨爾本的Port Botany。
ATSB展開調查，分析船舶的集裝箱堆朵和綁紮佈置，其穩定狀況，事故發生後船舶人員和船員的行為以及事故發生時的天氣狀況。
