When Overseas Shipholding Group (OSG) sought to install a ballast water treatment system on one of the Florida company’s tankers as it operated in Asia, the shipowner thought the equipment would arrive 21 days before work was scheduled to start at a shipyard in South Korea.

But a deeply congested container supply chain sent the shipment along a series of clogged transport legs, and the cargo arrived six weeks late.

“The container movement out of Fort Lauderdale to reach Korea was like a Jules Verne novel,” OSG chief executive Samuel Norton told TradeWinds.
