Section 3 Intermediate Surveys – Hull and machinery requirements3.1 General3.1.1 Intermediate Surveys are to be held concurrently with statutory annual or other relevant statutory surveys wherever practicable. 3.2 Intermediate Surveys3.2.1 The requirements of Pt 1, Ch 3, 2 Annual Surveys – Hull and machinery requirements are to be complied with, so far as applicable. 3.2.2 A general examination of salt-water ballast spaces is to be carried out by the Surveyor as required by Pt 1, Ch 3, 3.2 Intermediate Surveys and Pt 1, Ch 3, 3.2 Intermediate Surveys. If such examinations reveal no visible structural defects, the examination may be limited to a verification that the protective coating remains in GOOD or FAIR condition, as defined in Pt 1, Ch 3, 1.5 Definitions. When considered necessary by the Surveyor, thickness measurement of the structure is to be carried out. 3.2.3 For all units over five years of age and up to 10 years of age,
representative salt-water ballast tanks and other spaces are to be examined as
follows:
For tanks other than independent double bottom tanks, where a protective coating is found in POOR condition, as defined inPt 1, Ch 3, 1.5 Definitions, or other defects are found, where a soft or semi-hard coating has been applied or where a protective coating was not applied from the time of construction, the examination is to be extended to other ballast tanks of the same type. For independent double bottom tanks where substantial corrosion or other defects are found, the examination is to be extended to other ballast tanks of the same type. 3.2.4 For all unit types over 10 years of age, the following is required:
3.2.5 The Surveyor is to carry out an examination and thickness measurement of structure identified at the previous Special Survey as having substantial corrosion, see Section 5. 3.2.6 In addition to 3.2.1 to 3.2.7 on units with crude oil bulk storage
tanks, the following are to be dealt with where applicable:
3.2.7 For all units, the electrical generating sets are to be examined under working conditions to verify compliance with Pt 6, Ch 2, 2.2 Number and rating of generators and converting equipment. 3.2.8 The following are to be examined where accessible:
3.2.9 For units with crude oil bulk storage tanks, in addition to 3.2.6, the
following is required for units over 10 years and less than 15 years of age:
3.2.10 For units with crude oil bulk storage tanks, in addition to 3.2.8 and
3.2.11, the following is required for units over 15 years of age:
3.2.11 For natural gas fuel installations see also Pt 1, Ch 3, 21.7 Intermediate Surveys. |
