MEMORANDUM CIRCULAR
NUMBER ........................ 03-98
 (Corrected copy)

 

GUIDELINES ON MOVEMENTS OF VESSELS
DURING HEAVY WEATHER

 

  1. AUTHORITY:
     RA 5173 as amended by PD 601
     

  2. PURPOSE:
     To prescribe policies and procedures in order to enhance maritime safety especially during the occurrence of a tropical depression or typhoon that makes sea travel dangerous.
     

  3. SCOPE:
     This policy applies to all vessels that may be affected by the prevailing weather disturbance.
     

  4. DEFINITION OF TERMS
     

    1. Typhoon Signal Nr 1. - is declared if winds of 30-60 kph (approximately 16-32 knots) are expected in at least 36 hours.
       

    2. Typhoon Signal Nr 2 - is raised if winds of greater than  60 kph up to 100 kph (approximately 32-54 knots) is expected in the locality in at least 24 hours.
       

    3. Typhoon Signal Nr. 3 - is raised if winds of greater than 100 kph up to 185 kph (approximately 54-100 knots) is expected in at least 18 hours usually accompanied by heavy rains.
       

    4. Typhoon Signal Nr. 4 - is raised if winds of greater than 185 kph (approximately 100 knots) is expected in the locality in at least 12 hours usually accompanied by heavy rains.
       

    5. Danger Sector - is defined as the area where a typhoon may probably pass during the next 48 hours graphically constructed as follows:
       

      1. From the last known position of the typhoon, draw lines 40 degrees on both sides of the typhoon track.
         

      2. Take the maximum predicted distance that the typhoon travels during the next 48 hours
         

      3. Using the last known position of the typhoon as the center, draw an arc with a radius equal to the predicted distance determined in the para E2 above. The area bounded by this arc and the two radial lines drawn in para E1 above is the DANGER SECTOR.
         

    6. Vessel - Any ship, watercraft or other conveyances used or capable of being used as a means of transportation.
       

  5. POLICY:
     

    1. General: 
       

      1. Safety of Life at Sea should take precedence at all times. Whenever there is a weather disturbance within the Philippine area of responsibility (AOR), the PCG Station Commander (from the AOR any vessel is scheduled to depart) and the operator master of the vessel should study carefully the typhoon movement to ensure that the vessel will not be within the area covered by typhoon signals 1, 2, 3 and 4 or within the danger sector until they reach their destination.
         

      2. In the careful study of the typhoon movement, the Station Commander merely assists the master of the vessel by providing the necessary information from which the master formulates his own decision either to stay in port or move the vessel away from the typhoon. The technical information supported by the Station Commander shall not, in any manner, be construed as an advice for the master on his possible courses of action to avoid the typhoon.
         

      3. It is expected that shipowners/masters of the vessels will act according to their best judgment in order to save lives and property.

       

    2. Specific Guidelines:
       

      1. No craft/vessel of 1,000 gross tons or below shall sail except to take shelter if public storm warning signal (PSWS) Number 1 is hoisted within its point of origin, the route and point of destination.
         

      2. No vessel of 2,000 gross tons or below shall sail except to take shelter if PSWS Number 2 is hoisted within its point of origin, the route and point of destination.
         

      3. No vessel shall sail except to take shelter if PSWS Number 3/ PSWS Number 4 is hoisted within its point of origin, the route and point of destination.
         

      4. Vessels may be allowed to take shelter or ride out the storm without passengers or cargo on board.
         

      5. Station Commanders may exercise to the best of their professional judgment in allowing vessels/craft to operate on rivers or inland waterway if PSWS Number 1 is hoisted over said area.
         

      6. The PCG Boarding Teams must advise the Master of the vessel on the current weather report and forecast prior to the departure of the vessel.
         

    3. Para V, B may be superseded by a special instruction from the Commandant, Philippine Coast Guard or of his authorized representative.
       

  6. PROCEDURES:
     

    1. Every Master or any person-in-charge of the vessel shall ensure that the latest weather bulletin is received and the track of the typhoon is plotted on the weather chart aboardship.
       

    2. The Master or Patron, upon sensing of the danger as a result of a typhoon, shall request in writing to leave the port (if necessary) in order to take shelter in a safer sea, attesting therein further that the decision to leave the port is his alone.
       

    3. The Master or Patron must disembark passengers and cargo before leaving port to take shelter at a safer place.
       

    4. It is the responsibility of the Master of the vessel to take the necessary precaution to avoid risking his ship and injury to his crew and passengers.
