The Coast Guard is responsible for maintaining regulations for assigning gross and net tonnages and registered dimensions to vessels. These regulations are found in title 46, Code of Federal Regulations (CFR), part 69, Measurement of Vessels. A Federal Register notice published on December 22, 2003 (68 FR 71118), describes the process by which the Coast Guard establishes interpretations of these regulations to respond to novel situations, on a case-by-case basis, through policy decisions, and summarizes the interpretations in the MTN. Periodically, these interpretations are evaluated as to their appropriateness for incorporation into the tonnage measurement regulations.
The MTN is maintained by the Coast Guard Marine Safety Center (MSC) and is posted on the MSC's Web site at http://www.uscg.mil/hq/msc. A copy of the current version of the MTN is available in the docket (see “Viewing Comments and Documents,” above). While the MTN is intended for use by organizations authorized to perform tonnage measurement on behalf of the Coast Guard, the Coast Guard recognizes that it contains information that may affect decisions on vessel designs and that the public may benefit by our making it widely available to parties other than authorized measurement organizations.
Change 7 to the MTN
The MSC periodically issues changes to the MTN to keep it up-to-date with relevant policy decisions. The most recent change (Change 7) was issued on March 29, 2005. Change 7 includes the following:
1. Clarifications on the treatment of overhanging roofs when evaluating excludable space associated with end openings.
2. Correction of an inconsistency introduced in a previous change to the MTN regarding treatment of partial decks.
3. Criteria for assessing when deck recesses and other discontinuities in the uppermost complete deck and the tonnage deck invalidate the “stem to stern” and “side to side” requirement for such decks, or can otherwise affect the location of the line of the respective deck.
4. Clarification of the method by which volumes of outside shaft tunnels and other hull recesses and deck recesses are not included in under-deck tonnage.
5. Clarification of the method of establishing offset adjustments when calculating the under-deck tonnage of vessels with unconventional hull forms.
6. Clarifications on the treatment of water closet spaces contained within passenger spaces occupied by more than one person.
7. Interpretations prohibiting the exemption as passenger space of space that rests on a break deck that is part of the uppermost complete deck.
8. Clarifications on the treatment as open space of semi-enclosed spaces that are outside the boundary bulkhead of a structure.
9. Interpretations relative to the treatment of exemptible water ballast tanks that consist of contiguous but distinct spaces of varying shapes and sizes.
10. Clarification that certain deductible spaces may be included in tonnage upon request of the vessel owner.
11. Clarification that dry cargo and stores spaces are any spaces not occupied by liquids or used for the accommodation or berthing of passengers or crew.
12. Criteria for assessing when watertight bulwarks and similar structures are included in the overall length. Start Printed Page 20925
To provide a mechanism for notification when a change to the MTN has been issued, the MSC's web site allows members of the public to add their e-mail addresses to an electronic mailing list for such notification. Also, the Coast Guard will continue to notify the public via a notice in the Federal Register of changes to the MTN that are believed to be of significant interest to the maritime industry.Start Signature
