46 CFR § 69.17 - Application for measurement services.
(a) The vessel owner is responsible for having the vessel measured or remeasured under this part. Applications for Formal Measurement may be obtained from any measurement organization and, once completed, are submitted to the authorized measurement organization that will perform the measurement services. Applications for Simplified Measurement may be obtained from the Commanding Officer, Marine Safety Center (MSC-4) and, once completed, are submitted or retained as described in § 69.205. The contents of the application are described in this part under the requirements for each system.
(b) Applications for measurement under more than one system may be combined.
(c) For vessels under construction, the application should be submitted before the vessel is advanced in construction. Usually, this means as soon as the decks are laid, holds cleared of encumbrances, engines installed, and accommodations partitioned.
