Owners claimed a balance of T/C hire in an LMAA SCP arbitration. Charterers counterclaimed in respect of underperformance, but Owners argued that the counterclaim was not advanced within the mandatory time frame of Paragraph 5(g) of the SCP, obliging the Tribunal to shut it out. The Tribunal ruled that 5(g) was not a barring provision but nonetheless it could not adjudicate the counterclaim, as the T/C provided that in the event of a speed and consumption dispute, performance was to be analysed by “a mutually agreed weather routing company …whose findings will be final and binding” - which was absent. Owners were awarded their balance of hire claim (with some adjustments) and costs, but the Tribunal reserved jurisdiction to deal with Charterers’ counterclaim in the future, if advanced with a qualifying weather routing company analysis.
