Imperial Marine Company (the shipowner) and Deiulemar Compagnia di Navigazione Spa (the charterer) concluded a long-term NYPE time charter in 2003 for the bulk carrier George T. Disputes arose from 2005 onwards. The charterer supplied bunkers at Yeo Su, Korea that were out of specification, after which the vessel’s main engine suffered serious damage, leading to diversions, delays, and extensive repairs in Greece. Deiulemar treated the vessel as off-hire and commenced London arbitration alleging breaches of the owner’s obligations to deliver and maintain a seaworthy vessel. Imperial Marine disputed liability, blamed the defective bunkers, counterclaimed for unpaid hire, repair costs, and diminution in value. Further disputes arose regarding alleged unsafe port/berth damage at Richards Bay and extensive corrosion (allegedly caused by sulphate-reducing bacteria) discovered during later repairs. While arbitration was pending, Imperial Marine arrested two Deiulemar vessels, the Pasquale della Gatta and the Filippo Lembo, in South Africa under the Admiralty Jurisdiction Regulation Act 105 of 1983 to obtain security for its claims. Deiulemar opposed the arrests and sought counter-security for its own arbitration claims. The Western Cape High Court made mixed orders, prompting appeals and cross-appeals to the Supreme Court of Appeal.
