McDermott, Inc./Gates Construction Co., Inc. inspection workers considered as seamen

Summary OSHA reviewed whether workers on an inspected pipe-laying barge were land-based maritime workers or seamen. It concluded that their berthing and meals aboard the vessel, together with their work contributing to the vessel’s pipe-laying mission, made them seamen. OSHA therefore applied its 1983 agreement with the U.S. Coast Guard concerning safety authority over seamen on inspected vessels.

SUBJECT: McDermott, Inc./Gates Construction Co., Inc. OSHRC #s 91-3421, 92-0216 Insp. #s 100993179, 100993153


This interpretation is in response to the memorandum of David L. Baskin to Mark Lerner, OSH Division, NSOL dated March 10, 1993, regarding the subject consolidated case.
After discussing the jurisdictional matters involved in this case with NSOL (M. Lerner) and U.S. Coast Guard Headquarters (LCDR C. Barker, G-M19) we are of the opinion that the workers in question on McDermott Lay Barge 29 (an "inspected" pipe laying barge) are considered seamen for the following reasons:

The employees had a more or less permanent connection with the vessel which was established by their berthing and messing onboard the vessel and, therefore, they are not considered to be land-based maritime workers.
The employees contributed to the function of the vessel and to the accomplishment of its mission which was to lay pipe.

Therefore, the 1983 Memorandum of Understanding between OSHA and the U.S. Coast Guard concerning the authority to prescribe and enforce standards or regulations affecting the occupational safety and health of seamen aboard vessels inspected and certificated by the U.S. Coast Guard is applicable to the subject barge workers.
