NOTES

  • Column (1)-Sufficient particulars must be given to Identify the gear, for example, in the case of a winch or derrick, the number of the hold, etc., should be shown.
  • Column (2)-As a rule, a derrick, should be tested with its boom at the minimum angle to the horizontal for which the derrick system Is designed (generally 15), or at such greater angle as may be agreed.

    "Competent person" means:-

    • a person belonging to a testing establishment in India who is approved by Chief Inspector for the purposes of testing, examination or annealing and certification of lifting appliances, loose gears or wire ropes;
    • any other person who is recognised under the relevant regulations in force in other countries as competent for issuing certificates for any of the purposes mentioned in sub-clause(I)for implementation of the protection against Accidents (Dockers) Convention (Revised) 1932 (No. 32)and the Convention concerning the Occupational Safety and Health in Dock Work (No. 152), 1979,adopted by International Labour Conference.

INSTRUCTIONS

  • ILift appliances:-Every lifting appliance with its accessory gear, shall be subjected to a test load which shall exceed the safe working load (SWL) as follows:
    Safe Working LoadTest Load
    Upto 20 tonnes25 per cent in excess
    20 to 50 tonnes5 tonnes In excess
    Over 50 tonnes10 per cent in excess
  • Ship's derricks:
    • In the case of derrick system the test load shall be lifted with the ship's normal tackle with the derrick at the minimum angle to the horizontal for which the derrick system is designed (generally 15 degrees), or at such greater angle as may be agreed. The angle at which the test was made should be stated In the certificate of test. After the test load has been lifted, it should be swung as far as possible in both the directions.
    • A derrick boom designed to be raised with power with the load suspended shall in addition to the above test at (a), be raised (with the load suspended) to its maximum working angle to the horizontal at the two out most positions.
    • While test load testing of a heavy lift derrick, the competent person responsible for test using movable weights shall ascertain from the Master that the ship's stability will be adequate for the test.
  • The derrick tested under Cl. (2) shall not be used in union purchase rig unless-
    • the derricks rigged in union purchase are tested with the test load appropriate to the SWL in union purchase (at the designed head room and with the denick booms in their approved working positions);
    • the safe working load of that derrick in union purchase rig has also been specified by a competent person in a report in Form III;
    • any limitations or conditions specified in the said report are complied with; and
    • the two hoist ropes are coupled together by a suitable swivel assembly

    Note:The safe working loads of derricks (for each method of rig including union purchase) shall be shown on the Certificate of test and marked on the derrick booms.

  • Use of spring or hydraulic balances, etc. for test load testing:

    All tests normally shall be carried on with the help of dead weights. Test load testing on new ships shall always be with dead weights. In case of periodical tests, replacements or renewals, test load may be applied by means of a suitable spring or hydraulic balances. In such case, test load shall be applied with the boom as far out as practicable in both directions. The test shall not be taken as satisfactory unless the balance has been certified for accuracy by competent authority, within two per cent, and the pointer of the machine has remained constant as the test load for a period of at least 5 minutes.

  • Testing machines and dead weights:
    • A suitable testing machine shall be used for testing of chains, wire ropes, loose gears and other cargo gear.
    • Testing machines and balances to be used in test loading, testing and checking shall not be used unless they have been certified for accuracy at least once in the preceding 12 months by competent authority.
    • Moveable weights used for the test loading of the lifting appliance, loose gears and lifting device having a safe working load not exceeding 20 tonnes shall be checked for accuracy by means of suitable weighing machine.
  • Thorough examination after testing or test loading:

    After being tested or tested loaded, every lifting appliance, with their accessory gear shall be thoroughly examined to see that no part has been damaged or permanently deformed during the test. For this purpose, the lifting appliance or gear shall be dismantled to the extent considered necessary by the competent person.

  • In the case of heavy derricks, care should be taken to ensure that the appropriate shroude and stays are rigged.
  • The test and examination must be made by a competent person.
