Crowley Alaska Tankers, a part of Crowley Maritime Corporation, has completed the purchases of three tankers from ExxonMobil subsidiary SeaRiver Maritime with the intention of chartering the vessels back to Sea River.
The deal was first announced in November last year.
Crowley is renaming all three of the vessels after states along the west coast of the US.
The former Liberty Bay (114,814 dwt, built 2014) will now be called Washington, the former Eagle Bay (114,756 dwt, built 2015) will be California and the former American Progress will be Oregon (46,103 dwt, built 1997).
Liberty Bay and Eagle Bay had been transporting crude oil from Alaska to US west coast refineries, whereas American Progress had been delivering refined petroleum from the Gulf of Mexico to US east coast ports.
Jones Act-compliant Crowley has been operating in Alaska since 1953 and Crowley Alaska is headquartered in Bellingham, Washington, with a field office in Valdez, Alaska.
Parent company Crowley Maritime was founded in 1892 and is based in Jacksonville, Florida.
SeaRiver is headquartered in Spring, Texas.
