Okla. Stat. tit. 12A, § 12A-2-322: Delivery "Ex-Ship"

(1) Unless otherwise agreed a term for delivery of goods "ex-

ship" (which means from the carrying vessel) or in equivalent

language is not restricted to a particular ship and requires

delivery from a ship which has reached a place at the named port of

destination where goods of the kind are usually discharged.

(2) Under such a term unless otherwise agreed

(a) the seller must discharge all liens arising out of the

carriage and furnish the buyer with a direction which puts the

carrier under a duty to deliver the goods; and

(b) the risk of loss does not pass to the buyer until the

goods leave the ship's tackle or are otherwise properly unloaded.
