Extract of thickness measurements

Reference is made to the thickness measurements report:
Position of substantially corroded tanks/areas1 or areas with deep pitting3 Thickness diminution (%) Corrosion pattern2 Remarks: (e.g., ref. attached sketches)




     

 Notes :

1 Substantial corrosion, i.e., 75%-100% of acceptable margins wasted.

2P = Pitting

C = Corrosion in general

3 Any bottom plating with a pitting intensity of 20% or more, with wastage in the substantial corrosion range or having an average depth of pitting of 1/3 or more of actual plate thickness should be noted.

Tank corrosion prevention system

Tank Nos.1 Tank corrosion prevention system2 Coating condition3 Remarks




     

  1All segregated ballast tanks and combined cargo/ballast tanks should be listed.

2C = Coating

A = Anodes

NP = No protection

3 Coating condition according to the following standard:
  • GOOD - condition with only minor spot rusting.
  • FAIR - condition with local breakdown of coating at edges of stiffeners and weld connections and/or light rusting over 20% or more of areas under consideration, but less than as defined for POOR condition.
  • POOR - condition with general breakdown of coating over 20% or more of areas or hard scale at 10% or more of areas under consideration.
  • If coating condition "POOR" is given, extended annual surveys should be introduced. This should be noted in part 8 of the contents of the condition evaluation report.

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 2.1.1 of annex 12, and are found to be within their diminution limits determined by the Administration, taking into account the recommendations adopted by the Organizationfootnote, 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 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 2.1.1 of annex 12.

*2 Zreq means the diminution limit of the longitudinal bending strength of ships, as calculated in accordance with the provisions of paragraph 2.1.1 of annex 12.

The calculation sheets for Zact should be attached to this report.

  3 This section applies to ships constructed before 1 July 2002: Section moduli of transverse sections 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.

Describe 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.

Notes :

*1 As defined in note *1 of table 2.

*2 Zmc means the diminution limit of minimum section modulus calculated in accordance with provisions of paragraph 2.1.2 of annex 12.
