Summary
The High Court in The “Tian E Zuo” ([2018] SGHC 93) arose from two related collisions in Singapore waters on 12 June 2014 involving three principal vessels: the plaintiffs’ vessel Arctic Bridge, the defendant’s vessel Tian E Zuo, and the anchored vessel Stena Provence. The collisions occurred in the Western Petroleum Anchorage B and resulted in hull damage to varying extent. The parties had earlier settled with Stena Provence, agreeing between themselves that Stena Provence was not at fault, and that both sides would assume equal responsibility for Stena Provence’s damage, while preserving rights of indemnity between the parties.
In the present action, the plaintiffs sought a finding that the defendant was wholly to blame for the related collisions. The defendant, by counterclaim, argued that the plaintiffs were responsible and should bear 100% blame. The court’s central task was to determine whether each vessel committed “serious faults” and, crucially, whether any fault was causatively potent in producing the collisions. The court also considered whether the plaintiffs could rely on the defence of “agony of the moment” if the court found faults on the part of Arctic Bridge. Where the evidence could not determine the extent of blame, the court indicated that liability would be apportioned equally under section 1(1) of the Maritime Conventions Act 1911 (Cap IA3).
What Were the Facts of This Case?
The factual matrix was unusual and unfolded against a backdrop of congestion in an anchorage and adverse weather conditions. The collisions were preceded by an earlier incident involving the defendant’s vessel Tian E Zuo, a bunker barge Marine Liberty, and an oil tanker DL Navig8. At the material time, Tian E Zuo was anchored in the Western Petroleum B Anchorage. She was anchored by a single port anchor, six shackles deep, with a north-westerly heading. Marine Liberty was made fast to Tian E Zuo by mooring lines to her starboard side.
During a squall, Tian E Zuo dragged her port anchor. As a result, Tian E Zuo and Marine Liberty drifted into close proximity with DL Navig8. The extract records that at about 0308 hours Marine Liberty collided with DL Navig8, and at about 0314 hours Tian E Zuo collided with DL Navig8. These interactions created a predicament: the vessels became hampered by the presence of each other such that they could not unilaterally manoeuvre to clear and break free. This state persisted from about 0330 hours until between 0402 and 0406 hours, when Marine Liberty was freed at about 0402 hours. The extract notes that it was unclear precisely when DL Navig8 could safely move away, potentially between 0402 and 0406 hours.
Against this developing scenario, the principal collisions in dispute involved Stena Provence and two other vessels. The first related collision was between Stena Provence (at anchor) and Tian E Zuo. The second related collision was between Stena Provence and Arctic Bridge. The court’s analysis therefore required it to look at how the anchored and underway vessels interacted over time, and whether the chain of events leading to the collisions was continuous or whether there was a break in causation.
The court also described the relevant vessel characteristics and crew evidence. Arctic Bridge was a Korean-built chemical/oil tanker constructed in 2005, with gross tonnage of 30,053 and a bow thruster of 950 kW. She was partly loaded with 19,543 tonnes of gasoline. Two crew members testified: the master, Captain Erik Khuzhin, and the chief officer, Alexander Ignatyuk. Tian E Zuo was newer and larger, built in 2012, with gross tonnage of 43,718 and loaded with 56,114.984 tonnes of naphtha. Four crew members testified: the master, Captain Zou Zhizi, the chief officer Wu Binggao, the second officer Liu Bo, and an able-bodied seaman Zhang Guangyan.
Weather and tide conditions were also central. At 0245 hours, West Control broadcast a warning to all ships about strong winds and advised vessels to keep a good anchor watch. The squall was said to last from 0245 to 0320 hours (per the defendant’s Preliminary Act). Visibility remained moderate, and the court noted that those on board Arctic Bridge and Tian E Zuo could visually see each other for most of the incident. The experts agreed on tidal steam direction towards 119° true, with rates between 1.25 and 1.62 knots between 0245 and 0430 hours. The court accepted that prevailing wind direction was generally westerly to south-westerly after 0246 hours.
What Were the Key Legal Issues?
The first legal issue was fault: whether there were “serious faults” attributable to Tian E Zuo and/or Arctic Bridge in relation to the two related collisions. The plaintiffs’ case was that Tian E Zuo was negligent in permitting her anchor to drag initially, and that this earlier anchor drag triggered a chain of events culminating in the collisions approximately one hour and twenty minutes later. The defendant’s position was that the involuntary towage of Tian E Zuo effectively propelled her into contacting Stena Provence twice, thereby making Arctic Bridge responsible for the resulting damage.
The second legal issue concerned causation and whether the “but for” test could be applied in the manner urged by the plaintiffs. The plaintiffs relied on earlier events and argued there was no break in the chain of events, particularly because Arctic Bridge was forced to move away from her safely anchored position and had to dredge her port anchor due to the consequences of Tian E Zuo’s dragging. The court therefore had to evaluate whether the factual sequence was sufficiently continuous to treat the initial anchor drag as causatively potent for the later collisions.
The third legal issue was the applicability of the defence of “agony of the moment” if the court found faults on the part of Arctic Bridge. This defence typically arises where a vessel faces sudden and urgent circumstances requiring immediate action, and the law does not judge the vessel’s decisions with the same hindsight scrutiny as it would in ordinary circumstances. The court indicated it would examine whether the defence applied to the two occasions identified by the plaintiffs’ expert witness.
How Did the Court Analyse the Issues?
The court approached the dispute by focusing on causative potency and blameworthiness rather than merely identifying that something went wrong. It framed the question as whether one party was wholly to blame, or whether one party was “by far the most at fault”. This analytical framing is consistent with collision jurisprudence, where the court assesses not only the existence of fault but also the degree to which each fault contributed to the collision outcome.
On causation, the court scrutinised the plaintiffs’ reliance on the “but for” test. The plaintiffs’ theory depended on the proposition that the initial anchor drag by Tian E Zuo set in motion a chain of events that remained unbroken until the collisions with Stena Provence. The court therefore examined the timing and sequence of events, including the unusual circumstances in which Arctic Bridge was compelled to move away from her safely anchored position and had to dredge her port anchor. The court also noted that time references differed between parties’ sources, but held that exact timing differences did not affect the outcome because the precise timing of certain occurrences was immaterial to liability.
In evaluating the factual narrative, the court relied on multiple evidential sources, including AIS data and Voyage Data Recorder (VDR) reconstructions. The extract explains that the defendant’s expert produced plots using AIS data, and that the court also had graphical reference plots drawn from VDR data from the relevant vessels. However, the court cautioned that such reconstructions show what might have happened rather than what did happen, referencing its earlier decision in The “Dream Star” [2018] 4 SLR 473 at [13]. This caution is important: it signals that the court treated reconstructions as aids, not definitive proof of the precise manoeuvres or causal dynamics.
Weather and visibility were treated as part of the fault analysis. The court accepted that the anchorage was congested and that West Control had warned vessels to keep a good anchor watch due to strong winds. The court also assessed whether the conditions were such that the crew could reasonably observe each other and take appropriate precautions. The extract shows that there was some dispute about visibility and wind direction, but the court resolved these disputes by accepting the prevailing wind direction generally westerly to south-westerly after 0246 hours, and by noting that visibility was moderate and that crew members could observe other vessels for most of the incident. This reasoning would bear on whether any alleged navigational decisions were made under conditions that required heightened vigilance.
Regarding the defence of “agony of the moment”, the court indicated it would examine whether it applied to two occasions identified by the plaintiffs’ expert witness. Although the extract does not reproduce the full discussion, it shows that the expert’s depiction of the conditions at the relevant times was inconsistent with other evidence. For example, Captain Walker’s supplemental report suggested that at 0337 hours conditions remained dark, heavy rain, strong winds, and congested anchorage with another vessel dragging and colliding. Yet the court noted that Captain Walker’s earlier report stated winds had abated to a fresh breeze at 0337 hours, and that the plaintiffs’ Preliminary Act recorded visibility as moderate. The court also relied on Captain Khuzhin’s own testimony that he could observe other vessels a mile out prior to 0337 hours. This illustrates the court’s method: it tested expert narratives against contemporaneous records and direct testimony before deciding whether the “agony of the moment” threshold was met.
Finally, the court addressed the scenario where the evidence might not allow it to determine the extent of each party’s blameworthiness. In that event, it indicated that liability would be apportioned equally under section 1(1) of the Maritime Conventions Act 1911. This statutory approach is significant because it provides a structured fallback when fault is established but the court cannot quantify relative contribution with sufficient confidence.
What Was the Outcome?
The extract provided does not include the final dispositive orders. However, the court’s stated framework makes clear that the outcome depended on (i) whether the court found serious faults on the part of Tian E Zuo and/or Arctic Bridge, (ii) whether those faults were causatively potent in producing the collisions, (iii) whether the defence of “agony of the moment” applied to any fault found on Arctic Bridge, and (iv) if blame could not be determined with sufficient precision, whether equal apportionment under section 1(1) of the Maritime Conventions Act would follow.
Practically, the decision would determine whether the plaintiffs could shift liability entirely to Tian E Zuo, whether the defendant could succeed in obtaining a 100% blame finding against Arctic Bridge, or whether the court would apportion liability (potentially equally) between the parties for their indemnity exposure arising from the earlier settlement with Stena Provence.
Why Does This Case Matter?
The “Tian E Zuo” is instructive for practitioners because it demonstrates how Singapore courts approach complex collision causation in congested anchorage settings, especially where an initial incident (anchor drag) leads to later collisions after a significant time lapse. The judgment’s emphasis on causative potency and blameworthiness reflects a mature collision analysis: fault is not assessed in isolation, and the court scrutinises whether the alleged fault actually produced the collision outcome in a legally meaningful way.
The case is also useful for evidential practice. The court’s discussion of AIS and VDR-based reconstructions, and its caution that such materials may show what might have happened rather than what did happen, is a reminder that technical reconstructions must be treated with appropriate caution. Lawyers should therefore ensure that expert evidence is anchored in contemporaneous records and consistent with direct testimony, and should anticipate judicial scepticism where reconstructions are presented as definitive.
Finally, the judgment highlights the operational relevance of statutory fallback rules. The Maritime Conventions Act’s equal apportionment mechanism becomes critical where the court cannot determine relative blame. This matters for settlement strategy and for litigation risk assessment: parties may prefer to settle indemnity disputes when the evidence is unlikely to support a clear allocation of blame, because the statutory default may lead to equal sharing even where each side believes it is the primary wrongdoer.
