Annex B - Code on the Enhanced Programme of Inspections During Surveys of Oil Tankers

 These amendments have been consolidated into ESP Code, Annex B

Part A - Code on the Enhanced Programme of Inspections During Surveys of Double-Hull Oil Tankers

  1 General

  24 At the end of paragraph 1.2.6, the following sentence is added:

  • "For transversely framed oil tankers, a transverse section includes adjacent frames and their end connections in way of transverse sections."

  25 In paragraph 1.2.7, the words "structural areas" are inserted between the words "identifiable critical" and "and/or suspect areas".

  26 At the end of paragraph 1.2.9, the words "a gauged (or measured) thickness between tnet + 0.5 mm and tnet" are replaced by the words "a measured thickness between tren + 0.5mm and tren. Renewal thickness (tren) is the minimum allowable thickness, in mm, below which renewal of structural members is to be carried out".

  27 In the first sentence of paragraph 1.2.10, the word "protective" is inserted between the words "full hard" and "coating".

  28 At the beginning of paragraph 1.2.16, the words "Special consideration or" are inserted before the words "specially considered".

  29 At the end of paragraph 1.3.1.5, the words "(combination carriers)" are added.

  30 The following new paragraph 1.3.3 is added after existing paragraph 1.3.2:

  • "1.3.3 Where the damage found on the structure mentioned in paragraph 1.3.1 above is isolated and of a localized nature which does not affect the ship's structural integrity (as for example a minor hole in a cross-deck strip), consideration may be given by the surveyor to allow an appropriate temporary repair to restore watertight or weathertight integrity after evaluation of the surrounding structure and impose an associated condition of classification or recommendation with a specific time limit in order to complete the permanent repair and retain classification."

  2 Renewal survey

  31 At the end of paragraph 2.1.1, the following sentence is added:

  • "When the renewal survey is commenced prior to the fourth annual survey, the entire survey is to be completed within 15 months if such work is to be credited to the renewal survey."

  32 The following new paragraph 2.1.6 is added after existing paragraph 2.1.5:

  • "2.1.6 Concurrent crediting to both intermediate survey and renewal survey for surveys and thickness measurements of spaces should not be acceptable."

  33 At the end of paragraph 2.5.2, the words "should have thickness measurements taken." are replaced by the words "are to be examined. Areas of substantial corrosion identified at previous surveys are to have thickness measurements taken".

  3 Annual survey

  34 At the end of paragraph 3.5.2, the following sentence is added:

  • "For oil tankers built under IACS Common Structural Rules, the identified substantial corrosion areas are required to be examined and additional thickness measurements are to be carried out."

  4 Intermediate survey

  35 The following new paragraph 4.1.4 is added after existing paragraph 4.1.3 and the existing paragraph 4.1.4 is renumbered as 4.1.5:

  • "4.1.4 For oil tankers built under IACS Common Structural Rules, the identified substantial corrosion areas are required to be examined and additional thickness measurements are to be carried out."

  6 Documentation on board

  36 At the end of paragraph 6.3.2, the following text is added:

  • "(for CSR ships these plans are to include for each structural element both the as-built and renewal thickness. Any thickness for voluntary addition is also to be clearly indicated on the plans. The midship section plan to be supplied on board the ship is to include the minimum allowable hull girder sectional properties for the tank transverse section in all cargo tanks)."

Part B - Code on the Enhanced Programme of Inspections during Surveys of Oil Tankers other than Double-Hull Oil Tankers

  1 General

  37 At the end of paragraph 1.2.5, the following sentence is added:

  • "For transversely framed oil tankers, a transverse section includes adjacent frames and their end connections in way of transverse sections."

  38 In paragraph 1.2.6, the words "structural areas" are inserted between the words "identifiable critical" and "and/or suspect areas".

  39 At the beginning of paragraph 1.2.15, the words "Special consideration or" are added before the words "specially considered".

  40 The following new paragraph 1.3.3 is added after the existing paragraph 1.3.2:

  • "1.3.3 Where the damage found on structure mentioned in paragraph 1.3.1 above is isolated and of a localized nature which does not affect the ship's structural integrity (as for example a minor hole in a cross-deck strip), consideration may be given by the surveyor to allow an appropriate temporary repair to restore watertight or weather tight integrity after evaluation of the surrounding structure and impose an associated condition of classification or recommendation with a specific time limit in order to complete the permanent repair and retain classification."

  42 The following new paragraph 2.1.7 is added after existing paragraph 2.1.6:

  • "2.1.7 Concurrent crediting to both intermediate survey and renewal survey for surveys and thickness measurements of spaces should not be acceptable."

  43 At the end of paragraph 2.5.2, the words "should have thickness measurements taken" are replaced by the words "are to be examined. Areas of substantial corrosion identified at previous surveys are to have thickness measurements taken."

  6 Documentation on board

  44 At the end of paragraph 6.3.1, the following text is added:

  • "(for CSR ships these plans are to include for each structural element both the as-built and renewal thickness. Any thickness for voluntary addition is also to be clearly indicated on the plans. The midship section plan to be supplied on board the ship is to include the minimum allowable hull girder sectional properties for hold transverse section in all cargo tanks)."
