新西兰交通事故调查委员会(TAIC)在完成对集装箱船"石岭号"的事故调查后,敦促政府制定明确标准禁止不合规船舶进入本国港口。
该船2023年曾两度因故障被救援拖回港口。
TAIC首席事故调查员纳文·科祖帕卡拉姆指出,低标准船舶不仅威胁船员安全,更危及引航员、码头工人等港口作业人员及新西兰海岸环境。
调查显示,"石岭号"存在多项缺陷记录,在新西兰水域航行时"几乎肯定不具备安全航行条件"。
**两次险情暴露系统性缺陷**
2023年4月15日,"石岭号"在引航员指挥下离开惠灵顿港时,突发全船断电导致主机停机。
船舶漂向浅水区,船员紧急抛双锚才避免搁浅,最终由港作拖轮拖回泊位检修。
调查发现事故根源在于辅发电机缸套裂纹——尽管该船持有海事部门和船级社的有效证书,但多个关键安全系统状况堪忧。
同年5月12日,该船再次出港后在新西兰外海避风时进入塔斯曼海域,又因舱底水污染润滑油导致主机故障。
船长发出遇险求救信号,恰巧新普利茅斯港有适航拖轮可用,才将其拖回惠灵顿。
TAIC报告指出,本应防止水油混合的橡胶隔膜多年未检已老化失效。
**监管漏洞亟待修补**
第二次事故后,新西兰海事局扣留该船强制检修。
TAIC现建议交通部立法赋予海事局禁止特定船舶入港的权限(目前澳大利亚海事安全局已具此权)。
委员会特别强调新西兰拖带救援资源匮乏——"石岭号"事件中恰有合适拖轮可用实属侥幸。
尽管政府已租赁远洋拖轮至2026年6月,并计划加强应急拖带能力,TAIC认为仍需建立更完善的海事事故响应体系。
报告同时揭露国际与本地监管体系对挂旗船的安全监督存在漏洞:船东可将运营安全责任转嫁他方而不受追责。
TAIC已要求新西兰海事局就此向国际海事组织(IMO)提请改革。

英文原文
The Transport Accident Investigation Commission (TAIC) has urged New Zealand to ban substandard ships under clear criteria, following its investigation into the container ship Shiling, which had to be rescued and towed back to port twice in 2023.
Naveen Kozhuppakalam, Chief Investigator of Accidents at TAIC, highlighted that substandard ships pose serious risks to their crews, New Zealanders working in ports and harbours, such as pilots, stevedores, and contractors, and to the country’s coastal environment.
According to the commission’s findings, the Shiling had a history of defects and was almost certainly unfit to sail safely while in New Zealand waters.
The first incident happened on 15 April 2023 when the Shiling was leaving Wellington under pilot guidance. As the ship began to turn into the harbour entrance channel, it suddenly lost all electrical power, which caused the main engine to stop working.
The ship drifted toward shallow waters, but the crew managed to prevent it from grounding by dropping both anchors. Harbour tugs then towed the vessel back to its berth for repairs.
Investigators found that the blackout was caused by a cracked cylinder liner in one of the ship’s auxiliary generators. Despite holding valid certificates from maritime authorities and classification societies, the Shiling had several safety-critical systems in poor condition.
After repairs, the ship left Wellington again on 12 May 2023. While sheltering from bad weather off the New Zealand coast, the vessel entered the Tasman Sea and suffered another engine failure. This time, bilge water had contaminated the lube oil, causing the main engine to stop.
The master sent a Mayday call for help. A tug capable of towing sailed from New Plymouth and brought the Shiling to sheltered waters before towing it back to Wellington for further repairs.
TAIC reported that rubber diaphragms designed to keep water out of the lube oil tank had deteriorated over time and had likely gone uninspected for years.
Following this second failure, Maritime New Zealand detained the Shiling for repairs and surveys. The ship eventually left New Zealand waters for Singapore in July 2023.
The commission is now urging the Ministry of Transport to consider laws that would give Maritime New Zealand the authority to ban certain ships from entering the country’s ports. This authority currently exists for the Australian Maritime Safety Authority.
TAIC also pointed out that New Zealand has limited towing and salvage resources. In the case of the Shiling, it was only by coincidence that a suitable tow vessel happened to be available in New Plymouth at the time.
Although the government has arranged for an open-ocean tug until June 2026 and is planning for better emergency towing, TAIC says more work is needed to build a strong response system for maritime incidents and improve rescue services.
TAIC also pointed out safety problems in how both international and local systems oversee foreign-flagged ships. It raised concerns that ship owners can shift their responsibility for safe operations to other companies without facing proper consequences. TAIC has asked Maritime New Zealand to take these issues to the International Maritime Organization for changes.
