According to the information, the ship arrived at 20o north latitude and 123o east longitude at 2:30am on May 7 and was operating in the area between 19o 50 minutes and 20o 10 minutes north latitude, and between 122o 48 minutes and 123o 25 minutes east longitude until 8:24am on May 9, Tsay said.
From midnight on May 9 to 6:18am that day, the ship was sailing west by south at a speed of between 3 knots and 8 knots (5.6kph and 14.8kph) before it arrived at 19o 57 minutes north latitude, 122o 48 minutes east longitude, where it sailed at a lower speed of between 0 knots and 1 knot, he said.
The data showed that the ship sailed at a speed of between 4 knots and 5 knots in an east-south-east direction at 8:24am that day, while its speed increased to 10 knots at 10:12am, when its location was measured at 19o 59 minutes north latitude, 122o 55 minutes east longitude, “presumably being chased” by the Philippine vessel, Tsay said.
Tsay said the ship lost power at 11:24am at 20o 7 minutes, 123o east longitude, when its speed was measured at zero, data showed.
Analysis of the information has showed that it “contained no disruption to data recording during the voyage,” meaning that that the VDR system was operational, Tsay said.
