01 - Certificates & Documentation › 011 - Ships Certificates › Certificate of Inspection (COI)
Issued 4 February 2022
Resolved
The statutes relating to inspection of public vessels are primarily contained in 46 U.S.C. 2101(24) and 2109.
a. 46 U.S.C. 2101(24) defines a public vessel as one that "is owned, or demise chartered, and operated by the United States Government or a government of a foreign country; and…is not engaged in commercial service."
The SIKULIAQ is owned by the National Science Foundation (NSF), is operated by the University of Alaska, and is not engaged in commercial service.
Government owned vessels as defined in 46 U.S.C. 2101(24) operated for oceanographic research are not required to be inspected and certificated by the Coast Guard. However, such vessels may be inspected and certificated upon request by the parent agency and upon an “interagency agreement to this effect.”
Without an interagency agreement, the Coast Guard does not have authority to conduct inspections, or casualty investigations on the SIKULIAQ.
ou are required to "establish" an interagency agreement between the National Science Foundation and the United States Coast Guard no later than February 4, 2023.
Failure to establish an interagency inspection agreement with the Coast Guard prior to February 4, 2023 will result in the vessel being deactivated in the Coast Guard's database. In addition, Coast Guard Sectors Puget Sound and Columbia River will not conduct inspections on the SIKULIAQ without an interagency inspection agreement.
The SIKULIAQ does not need a COI to operate as a Government owned Oceanographic Research Vessel. Failure to establish an inspection agreement will not limit vessel operations as a research vessel.
It is our understanding that NSF owns several research vessels and is constructing new vessels that are operating, or will be operating in a similar manner. It would be beneficial to enter all NSF owned research vessels under the same interagency agreement.
If you disagree with this decision you may ask for reconsideration, or appeal this decision in accordance with 46 CFR 1.03-20.
