Results of Inspections of MK-10 Submarine Escape and Immersion Equipment Life Rafts Following Leeway Testing; Technical rept. 2005-2006

摘要

NSMRL funded the United States Coast Guard Research and Development Center in Groton, Connecticut to conduct testing to determine the leeway coefficients for the Submarine Emergency Position Indicating Radio Beacons (SEPIRB) and the Mark-10 Submarine Escape and Immersion Equipment (MK-10 SEIE) single man life raft. This report is being generated due to concern for the quality and durability of the MK-10 SEIE life rafts as noted in the USCG Research and Development Center Draft Report of the Leeway Coefficients. Analysis of the leaks indicated that they appeared to have been caused by chaffing of the buoyancy chamber material or the manual inflation tube on objects inside the rafts. No buoyancy chamber seams failed. The raft leaks were caused by the test equipment mounting methods, test equipment or other objects placed inside the rafts chaffing the interior side of the raft buoyancy chamber or manual inflation tube and not due to poor manufacturer workmanship or construction materials.
