Oregon Revised Statutes Shipping and Navigation § 783.350

If the owner of the vessel is nonresident of and not within Oregon, service of the summons and complaint shall be made upon the master or person in charge of the vessel, with the same force and effect as though made by publication. In such event the owner shall be required to appear and answer to the complaint within the same time as though the owner were served personally. In such event no personal judgment against the owner shall be rendered in the action, but only an order of sale of the property attached, or, in event of such property being released upon undertaking, then judgment shall be rendered against the obligors thereon. In the event of the vessel belonging to nonresidents, defects in the names of parties defendant shall not in any respect affect the validity of the proceedings or of any judgment rendered therein.
