Leeway of Submarine Escape Rafts and Submarine Emergency Positioning Beacons
Bibliographic record
Abstract
The leeway behavior of Submarine Emergency Position Indicating Radio Beacons (SEPIRBs) and Mark-10 Submarine Escape and Immersion Equipment (SEIE) life rafts was measured for use in search and rescue planning. SEIE and SEPIRB drift targets were outfitted with position tracking equipment, and one raft was also equipped with a current profiler. The targets were deployed and tracked along with Self-Locating Datum Marker Buoys (SLDMBs) under generally heavy wind and sea conditions during fall 2005 on the Atlantic Ocean off St. John's, Newfoundland, Canada. The duration of each test ranged from 24 hours to approximately 60 hours. Maximum wind speeds (5-minute averages) ranged from just under 20 knots to nearly 40 knots, with gust speeds to 43 knots. SEIE and SEPIRB leeway speeds were determined either directly from the current profiler data or indirectly using the SLDMB data. Leeway coefficients for SAR planning use were calculated using the concurrent wind data. The leeway speed of the undrogued raft was greater than that of the drogued raft. The data indicate that SEPIRB leeway is zero. The study recommends that these coefficients be incorporated into submarine survivor search planning guidance. Problems with raft performance were encountered that were attributed to the installed instrument package, instrument mounting materials incompatibility and the absence of a human passenger in the high wind and wave environment. Issues with SEPIRB operation and performance are also noted.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
