No. 14 - Temporary reduction of the total number of persons on the PSSC of Dutch flag passenger vessels.

(Date Entry Into Force: 01-04-2012)

In accordance with art.40 of the Ships decree 2004, a ship for which a passenger ship safety certificate is required shall satisfy a.o. the requirements of chapter III of the SOLAS Convention.
Furthermore, in accordance with paragraph 5.8 of the agreement of June 1st 2006 between the Netherlands Shipping Inspectorate (NSI) and the RO’s (as amended), RO’s are permitted to withdraw the full term certificate on behalf of NSI in the case where the requirements of an applicable instrument cannot be met under particular circumstances, and issue a short-term certificate describing the required measures or supplementary equipment and the time limit for permanent repairs or rectification.
To avoid unnecessary delay and outside office hours, RO is allowed to issue short term certificates without prior consultation of the Administration, in which cases RO shall inform NSI afterwards as soon as possible.

In this respect the Recognized Organization may issue a short-term Passenger Ship Safety Certificate when survival craft is found damaged or otherwise not fit for service. In this case the following principles and procedures shall be followed:

  1. Non-conformity
    Survival craft found damaged or otherwise not fit for service effectively reduces the total number of persons the vessel may carry. If an RO surveyor finds survival craft damaged or otherwise not fit for service, the appropriate action would be repair or replacement of the defective survival craft. If this is not possible, the appropriate requirement would be a temporary reduction in the total persons allowed on the vessel.
    Based on the argument that SOLAS requires equal distribution of lifeboat arrangements on both sides of the vessel, the reduction would be more than the number of persons normally carried by the unfit lifeboat. However this particular SOLAS requirement is a design requirement for arranging lifeboats and stations on the vessel and this requirement does not apply to operational and temporary situations where individual lifesaving equipment is substandard.

  2. Temporary Reduction of Total Persons on Board
    Given that SOLAS lifeboat requirements for a passenger vessel presume that the ship has all of its required lifeboats and life rafts available during abandon ship, the RO should not normally require any reduction of total persons allowed beyond the lifeboat capacity lost due to damaged or otherwise not fit for service lifeboats or life rafts.

  3. Temporary Addition of Life Rafts for Lifeboats
    A vessel with a substandard lifeboat may fully or partially offset a reduction in total persons allowed by adding one or more SOLAS-approved life rafts on the appropriate side of the vessel. The vessel may only do so if it meets the following conditions: the life raft is capable of davit launch; the vessel provides the appropriate SOLAS-approved launching arrangements for the added life rafts; and the aggregate capacity of the remaining non-substandard lifeboats is not less than 75 percent of the reduced total number of persons on board the vessel (or 30 percent in case of short international voyages).

  4. Temporary Substitution of Existing Life Rafts for Lifeboats
    A vessel with a substandard lifeboat may offset a reduction in total persons allowed by changing the service of one or more of the existing rafts required by SOLAS Regulation III/21.1.1.2 on the appropriate side of the vessel. The vessel may only do this if it meets the conditions specified in paragraph 3. above.
    In addition, when considering a reduction in the total number of persons allowed, the RO should ensure that the change provides capacity requirements of SOLAS chapter III for the temporary reduction in total persons allowed. In formula’s this can be translated as follows:

    Reduction Y = Z – D, provided that:


    (C – D)/(X – Y) > 0.25 AND


    (A – Z)/(X – Y) > 0.75 (or 0.30 in case of short international voyages) AND


    (A – Z) + B > X – Y


    whereby:


    A=total lifeboat capacity (at least 75% of total number of persons on board, or 30% in case of short international voyages)
    B=

    total standard liferaft capacity

    C=total additional liferaft capacity (at least 25% of total number of persons on board)
    D=offset of reduction as part of C
    X=total number of persons allowed on board
    Y=reduction in total number of persons allowed on board
    Z=

    capacity lost due to substandard lifeboat



     For example:
    • A vessel that may carry 2270 total persons (= X) has 6 x 150 person lifeboats, 1 x 60 person rescueboat/lifeboat (together A/2) and 5 x 35 person life rafts (= B/2) as primary lifesaving equipment (i.e. the 100% requirement) on each side of the vessel. The vessel also has 18 x 35 person additional life rafts (= C) which exceeds the 25% additional life raft requirement. The vessel has one substandard 150 person lifeboat (= Z) on the starboard side.

    • When 2 of the existing additional liferafts are used to offset the reduction: Y = 150 – 70 = 80, while (630 – 70)/(2270 – 80) = 0,256 and (1920 – 150)/(2270 – 80) = 0,81 and (1920 – 150) + 350 = 2220 which is more than X – Y (2190). This would still be OK.

    • When 3 of the existing additional liferafts are used to offset the reduction: Y = 150 – 105 = 45, while (630 – 105)/(2270 – 45) = 0,236 and (1920 – 150)/(2270 – 45) = 0,79 and (1920 – 150) + 350 = 2220 which is more than X – Y (2190). This would still be OK for the lifeboat capacity and standard liferaft capacity, but NOT for the additional liferaft capacity.

  5. Temporary Reduction of Total Persons Allowed due to Substandard Life Rafts (that are part of the 25% requirement)
    If a life raft required under SOLAS Regulation III/21.1.2 is substandard, a reduction of total persons allowed beyond the capacity of the substandard life raft(s) may be appropriate.

    For example:
    • a vessel that meets the 100% lifeboat and liferaft requirement for 2800 total persons allowed must have an additional 700 person life raft aggregate capacity to meet the aforementioned (i.e. 25%) requirement.

    • If the vessel has lifeboats for 2220 persons and life rafts for 580 persons to meet the 100% requirement and 20 x 35 person life rafts to meet the 25% requirement, and two of the latter life rafts are substandard, then the vessel must account for this loss of capacity.

    • For this case, determine the total number of persons served by the lifeboats and all of the non-substandard life rafts. In this case, total survival craft capacity is 3430 persons (2220 plus 580 plus 700 minus 2x35).

    • Noting that the total lifeboat and life raft capacity  must be at least 125% of the total persons allowed, multiply this number by 0.8 to yield the reduced total persons allowed (2744).

  6. Implementation
    If a surveyor finds a required lifeboat or life raft not fit for duty:
    1. Require repair or replacement of the substandard lifesaving equipment before allowing the vessel to sail.

    2. In cases where the vessel cannot repair or replace the substandard equipment before sailing, require a reduction of total persons allowed commensurate with the number of persons served by the substandard lifesaving equipment.

    3. In cases where the substandard lifeboat also serves as a rescueboat, arrangements shall be made to prepare one of the other lifeboats (on the same side) to serve as a rescueboat. In this respect the applicable requirements of SOLAS (i.e. a.o. reg. III/14 and III/17) and the LSA Code (ch.V) shall be met to the maximum extent possible. The operating crew of the rescueboat shall be aware of any restrictions this change of application may incur.

    4. It should be noted that a change in LSA configuration in accordance with this ItoRO may require a rearrangement of crew duties in emergency/abandon ship procedures. An alteration of the musterlist due to this fact should be accounted for.

    5. This reduction in total persons allowed will remain effective until the vessel repairs or replaces the substandard lifesaving equipment. An appropriate period for temporary reductions in total persons allowed is 30 days. This period may be extended in exceptional cases.
