Typhoon season begins from Jun. to Nov. Sept. is the most seriously affected month.

Typhoon tracks of the area 5. Typhoon tracks 3 different typhoon tracks: Type1: Hainan island landing typhoon Type2: Passing by the southern part of Hainan island Type3: Landing or passing by the coastal area of Canton Province. Compared with type2, typhoons of type1&type3 cause greater impact to Qiongzhou strait,that's why we pay special attention to them.

6. Countermeasures to the different typhoon tracks 6.1 Typhoon landing at Hainan Island
when a typhoon attacks Haikou, and the wind force gusts up to 12, Haikou Bay anchorage will not be suitable for typhoon prevention, except those sheltered in New port inner anchorage, all the RO-RO passenger ships must be moved to Houshuiwan typhoon anchorage
![Page 16: typhoon prevention measures RO-RO Passenger Ship of ... Hurricane... · 6.

when typhoon passes by the southern part of Hainan Island, and the wind force is below 10, the impact caused to the RO-RO passenger ships will not be serious, so the ships are allowed to be berthing at the terminal or moved to Haikou Bay anchorage.

6. Countermeasures to the different typhoon tracks 6.3 Typhoon landing or passing by the coastal area of Canton Province
when the typhoon track is near Qiongzhou Strait but not hit Haikou directly, and the wind force is 10-12, RO-RO passenger ships below 3000GT may move to the New port inner anchorage, while ships above 3000GT will be sheltered at Haikou Bay anchorage or Houshuiwan anchorage.
