2.3 Detainable deficiencies

  2.3.1 In exercising his/her functions, the PSCO should use professional judgment to determine whether to detain the ship until any noted deficiencies are corrected or to allow it to sail with certain deficiencies which do not pose an unreasonable threat of harm to the marine environment. In doing this, the PSCO should be guided by the principle that the requirements contained in the Annex, with respect to the construction, equipment and operation of the ship, are essential for the protection of the marine environment and that departure from these requirements could constitute an unreasonable threat of harm to the marine environment.

  2.3.2 In order to assist the PSCO in the use of these guidelines, there follows a list of deficiencies, which are considered to be of such a serious nature that they may warrant the detention of the ship involved:

  • .1 absence of valid IAPP Certificate, EIAPP Certificates or Technical Filesfootnote;

  • .2 a diesel engine, with a power output of more than 130 kW, which is installed on board a ship constructed on or after 1 January 2000, or a diesel engine having undergone a major conversion on or after 1 January 2000, which does not comply with the NOx Technical Code;

  • .3 the sulphur content of any fuel oil being used on board exceeds 4.5% m/m.

  • .4 non-compliance with the relevant requirements while operating within an SOx emission control area;

  • .5 an incinerator installed on board the ship on or after 1 January 2000 does not comply with requirements contained in appendix IV to the Annex, or the standard specifications for shipboard incinerators developed by the Organization (resolutions MEPC.76(40) and MEPC.93(45));

  • .6 the master or crew are not familiar with essential procedures regarding the operation of air pollution prevention equipment as defined in paragraph 2.2.7 above.
