Salalah to Seattle shipping route.

Ships leaving Salalah for Seattle head north and cover a sea distance of 10,550 nautical miles (19,539 km), via Strait of Malacca. The straight line between the ports is 12,823 km; coastlines and shipping lanes add the rest. On the way the vessel passes Strait of Malacca.

Pure steaming time is 31.4 days at 14 knots. A carrier that slow steams at 12 knots to save fuel needs 36.6 days, and a fast 18 knot string about 24.4. 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 Salalah and Seattle to plan the full ocean transit time.

The next option is via Sunda Strait, 11,134 nautical miles, 583 nm longer than the main route. Carriers pick it when Sunda Strait is congested or closed.

548 nm of the route, 5% 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 Salalah to Seattle move with fuel prices, ship capacity and the season. Compare several carriers before booking: the cheapest sailing is often the slowest one. At Seattle (USSEA) carriers give about 3.94 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 Salalah in this directory, Seattle is the 62nd shortest. Closer destinations include Manzanillo (10,021 nm), Callao (9,718 nm) and Houston (8,730 nm).
