6.2 Survey Plan documentation

  6.2.1 In developing the Survey Plan, the following documentation shall be collected and reviewed with a view to identifying tanks, areas and structural elements to be examined:

  • .1 basic ship information and survey status;

  • .2 main structural plans of cargo and ballast tanks (scantling drawings), including information regarding use of high tensile steels (HTS);

  • .3 Condition Evaluation Report, according to Annex 9 of Annex B of resolution A.744(18), as amended, and, where relevant, any previous CAS Final Reports;

  • .4 thickness measurement reports;

  • .5 relevant previous damage and repair history;

  • .6 relevant previous survey and inspection reports from both the RO and the Company;

  • .7 cargo and ballast history for the last 3 years, including carriage of cargo under heated conditions;

  • .8 details of the inert gas plant and tank cleaning procedures as indicated in the Survey Planning Questionnaire;

  • .9 information and other relevant data regarding conversion or modification of the ship’s cargo and ballast tanks since the time of construction;

  • .10 description and history of the coating and corrosion protection system (including anodes and previous class notations), if any;

  • .11 inspections by the Company’s personnel during the last 3 years with reference to:

    • .1 structural deterioration in general;

    • .2 leakages in tank boundaries and piping;

  • .12 information regarding the relevant maintenance level during operation including:

    • .1 port State control reports of inspection containing hull related deficiencies;

    • .2 Safety Management System non-conformities relating to hull maintenance, including the associated corrective action(s); and

  • .13 any other information that will help identify Suspect Areas and Critical Structural Areas.

  6.2.2 The Survey Plan shall include relevant information so as to enable the successful and efficient execution of the CAS survey and shall set out the requirements with respect to close-up surveys and thickness measurements. The Survey Plan shall include:

  • .1 basic ship information and particulars;

  • .2 main structural plans of cargo and ballast tanks (scantling drawings), including information regarding use of high tensile steels (HTS);

  • .3 arrangement of tanks;

  • .4 list of tanks with information on their use, extent of coatings and corrosion protection systems;

  • .5 conditions for survey (e.g. information regarding tank cleaning, gas freeing, ventilation, lighting, etc.);

  • .6 provisions and methods for access to structures;

  • .7 equipment for surveys;

  • .8 identification of tanks and areas for the close-up survey;

  • .9 identification of tanks for tank testing, as per Annex 3 of Annex B of resolution A.744(18), as amended;

  • .10 identification of areas and sections for thickness measurement;

  • .11 identification of the Thickness Measurement (TM) firm;

  • .12 damage experience related to the ship in question; and

  • .13 Critical Structural Areas and Suspect Areas, where relevant.

  6.2.3 The Survey Plan shall be developed using the Model Survey Plan for CAS set out in Appendix 3.
