Annex 9 - Condition Evaluation Report

Parent topic: Part B - Guidelines on the Enhanced Programme of Inspections During Surveys of Oil Tankers other than Double Hull Oil Tankers

Evaluation result of longitudinal strength of the hull girder of oil tankers of 130 m in length and upwards and of over 10 years of age (Of sections 1, 2 and 3 below, only one applicable section should be completed)

  1 This section applies to ships regardless of the date of construction: Transverse sectional areas of deck flange (deck plating and deck longitudinals) and bottom flange (bottom shell plating and bottom longitudinals) of the ship's hull girder have been calculated by using the thickness measured, renewed or reinforced, as appropriate, during the renewal survey of the Cargo Ship Safety Construction Certificate or the Cargo Ship Safety Certificate (SC renewal survey) most recently conducted after the ship reached 10 years of age, and found that the diminution of the transverse sectional area does not exceed 10% of the as-built area, as shown in the following table:

Table 1 Transverse sectional area of hull girder flange
  Measured As built Diminution
Transverse Section 1 Deck Flange cm2 cm2 cm2( %)
Bottom flange cm2 cm2 cm2( %)
Transverse Section 2 Deck Flange cm2 cm2 cm2( %)
Bottom flange cm2 cm2 cm2( %)
Transverse Section 3 Deck Flange cm2 cm2 cm2( %)
Bottom flange cm2 cm2 cm2( %)

  2 This section applies to ships constructed on or after 1 July 2002: Section moduli of transverse section of the ship's hull girder have been calculated by using the thickness of structural members measured, renewed or reinforced, as appropriate, during the SC renewal survey most recently conducted after the ship reached 10 years of age in accordance with the provisions of paragraph 2.2.1.1 of annex 12, and are found to be within their diminution limits determined by the Administration, taking into account the recommendations adopted by the Organization, as shown in the following table:

Table 2 Transverse section modulus of hull girder
  Zact(cm3)*1 Zreq(cm3)*2 Remarks
Transverse Section 1 Upper Deck      
Bottom      
Transverse Section 2 Upper Deck      
Bottom      
Transverse Section 3 Upper Deck      
Bottom      

Notes

*1 Zactmeans the actual section mooduli of the transverse section of the ship's hull girder calculated by using the thickness of structural members measured, renewed or reinforced, as appropriate, during the SC renewal survey, in accordance with the provisions of paragraph 2.2.1.1 of annex 12.

*2Zreqmeans diminution limit of longitudinal bending strength of ships as calculated in accordance with the provisions of paragraph 2.2.1.1 of annex 12

 The calculation sheets for Z act should be attached to this report.

  3 This section applies to ships constructed before 1 July 2002: Section moduli of transverse section of the ship's hull girder have been calculated by using the thickness of structural members measured, renewed or reinforced, as appropriate, during the SC renewal survey most recently conducted after the ship reached 10 years of age in accordance with the provisions of paragraph 2.2.1.2 of annex 12, and found to meet the criteria required by the Administration or the recognized classification society and that Zact is not less than Zmc (defined in *2 below) as specified in appendix 2 to annex 12, as shown in the following table:

Table 3 Transverse section modulus of hull girder
  Zact(cm3)*1 Zmc(cm3)*2 Remarks
Transverse Section 1 Bottom      
Upper Deck      
Transverse Section 2 Bottom      
Upper Deck      
Transverse Section 3 Bottom      
Upper Deck      

Notes

*1 As defined in note *1 of Table 2

*2Zmc means the diminution limit of minimum section modulus calculated in accordance with provisions of paragraph 2.2.1.2 of annex 12

  Notes

  *1 Zact means the actual section moduli of the transverse section of the ship's hull girder calculated by using the thickness of structural members measured, renewed or reinforced, as appropriate, during the SC renewal survey, in accordance with the provisions of paragraph 2.2.1.1 of annex 12.

  *2 Zreq means diminution limit of the longitudinal bending strength of ships, as calculated in accordance with the provisions of paragraph 2.2.1.1 of annex 12.

 Describes the criteria for acceptance of the minimum section moduli of the ship's hull girder for ships in service required by the Administration or the recognized classification society.
