Drummond Co. affiliate Interocean has notified customers for coal it exports from Colombia that it has been forced to declare Force Majeure as a result of the Colombian government’s decision to halt—effective January 13—all coal shipments from its operations within the country, company officials announced on January 10. The company, which suffered from a two-month labor strike in 2013, said last year’s work stoppage caused a delay in the construction of its new port. Drummond expects a conveyor system that loads ships directly to be ready in March of this year.
