Oakland to Colombo shipping route.

The shipping route from Oakland, United States to Colombo, Sri Lanka covers 9,041 nautical miles port to port, via Strait of Malacca. On a globe the two ports sit 14,534 km apart, so the ship sails 1.15 times the straight line distance. On the way the vessel passes Strait of Malacca.

Pure steaming time is 26.9 days at 14 knots. A carrier that slow steams at 12 knots to save fuel needs 31.4 days, and a fast 18 knot string about 20.9. Container transit time on a liner service is longer than the steaming time: ships call at other ports on the rotation, and cargo may transship at a hub. Add terminal time at Oakland and Colombo to plan the full ocean transit time.

The next option is via Sunda Strait, 9,616 nautical miles, 575 nm longer than the main route. Carriers pick it when Sunda Strait is congested or closed.

348 nm of the route, 4% of it, lies inside North American ECA. In an emission control area ships must burn fuel with no more than 0.1% sulphur or clean the exhaust with scrubbers. That fuel costs more, and carriers add it to the ocean freight bill as a low sulphur or ECA surcharge.

Container freight rates on Oakland to Colombo move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Colombo (LKCMB) carriers give about 5 free days before demurrage and detention charges start, so plan the truck or rail pickup before the box lands.

Of the 65 port to port routes from Oakland in this directory, Colombo is the 52nd shortest. Closer destinations include Gdansk (8,903 nm), Marsaxlokk (8,729 nm) and Lagos (Apapa) (8,631 nm).
