A Mission Data Recorder (MDR) was designed and built by the Coast Guard RD Center to support the Operational Test and Evaluation (OTE) of the 47-Ft Motor Lifeboat (MLB). The purpose of the MDR was to collect both short-term event data and long-term vessel motions data in an autonomous manner, similar to an aircraft flight data recorder. Phase 1 results were published in Coast Guard Mission Data Recorder (MDR) for the 47-Ft Motor Lifeboat, Report No. CG-D-20-94. Phase 2 follow-on data collection includes the recording of one significant event which was recorded during a towing operation. Statistics data for the Phase 2 period of June 1994 to March 1995 were collected and analyzed. Heave acceleration and roll frequency distribution curves were developed for each boat. The MDRs will remain onboard the 47-Ft MLBs for an additional year to continue monitoring for significant motion events and to collect data on how the boats will be used following the close scrutiny of the OTE. (AN).
