| 词条 | Emergency wreck buoy |
| 释义 |
An Emergency wreck buoy is used to warn of a new wreck which has not yet been listed in maritime documents. The buoy is expected to be deployed for the first 24-72 hours after the wreck occurs. After that time more permanent buoyage (such as isolated danger marks or cardinal marks should be deployed and charts updated.[1] The buoy is designed to provide to "provide a clear and unambiguous"[1] mark of a new and uncharted danger. The buoy is painted with 4, 6 or 8 vertical stripes of alternate yellow and blue. In addition it may have the word "WRECK" painted on it. Optionally it may carry a vertical (St. George's) cross painted yellow. The light flashes alternate yellow and blue for one second each with a half second gap between. No other navigation mark uses blue.[2] The IALA (International association of maritime aids to navigation and lighthouse authorities) defined the buoy in response to the sinking of the {{MV|Tricolor}} and the subsequent collisions with the wreck by the Dutch vessel Nicola and Turkish-registered fuel carrier Vicky.
