In London Arbitration 7\/25<\/a><\/em>, a key issue before the tribunal was the vessel\u2019s performance under an amended NYPE 1993 charterparty. The dispute centred on whether the vessel had breached the speed and consumption warranty, how performance should be assessed in relation to weather conditions, and whose evidence\u2014master or weather routing company\u2014should prevail. The arbitrator\u2019s analysis provides valuable guidance on the interpretation of performance warranties and the allocation of evidentiary burdens in time charter disputes.<\/p>\n The charterparty included a detailed additional clause on performance, stating that the vessel was warranted to achieve:<\/p>\n Performance was expressly stated to apply \u201c<\/strong>in good weather conditions (abt to mean +\/- 5%) and up to Beaufort Force 4 (BF4) and Douglas Sea State 3, with no adverse current.\u201d Calculations were to be based only on such \u201cgood weather\u201d days, and \u201call details\u201d were given \u201cabout\/in good faith and without guarantee.\u201d<\/p>\n This clause raised several interpretive issues:<\/p>\n The arbitrator approached the clause by referencing industry standards and previous case law:<\/p>\n The charterers alleged that the vessel underperformed, relying heavily on a report from a weather routing company (WRC). They argued the report showed the vessel had failed to achieve the warranted speeds during good weather conditions and claimed the master had sailed at \u201ceco speed\u201d without justification. Additionally, they hinted that hull fouling may have impacted performance.<\/p>\n The owners challenged these assertions, stating:<\/p>\n The arbitrator ruled decisively in favour of the owners:<\/p>\n This case underscores several important points for both shipowners and charterers:<\/p>\n The performance analysis in London Arbitration 7\/25<\/em> serves as a practical guide for interpreting and applying speed and consumption warranties in time charter disputes. The case confirms that where clear definitions exist in a charterparty, tribunals will apply them strictly, and unsupported claims of underperformance<\/a> will not suffice. Parties must, therefore, ensure they have accurate, consistent records and a proper understanding of the contractual terms if they are to assert\u2014or defend against\u2014claims of non-performance.<\/p>\n At Lester Aldridge, our maritime law specialists<\/a> provide clear, practical advice on charterparty disputes, vessel performance claims, and arbitration matters.The Performance Clause and Its Key Terms<\/h2>\n
