Section 1 Conditions for verification

1.1 General requirements

1.1.1 It is the responsibility of Owners, Operators or Duty Holders to comply with all aspects of National Legislation applicable to units and installations engaged in petroleum activities in controlled waters.

1.1.2 When LR is requested by an Owner, Operator or Duty Holder to carry out verification in accordance with the Regulations of the coastal state authority, verification approval will be carried out in accordance with this Chapter.

1.1.3 Verification will be carried out to the specific provisions of the coastal state Regulations, as agreed with the Owner, Operator or Duty Holder, and appropriate to the proposed descriptive note and the type of unit and its function.

1.1.4 For the assignment of a National Authority descriptive note as defined in Pt 1, Ch 2, 2.9 Descriptive Notes/Supplementary Character 2.9.2, compliance with the coastal state Regulations will be considered in addition to the requirements of the Rules.

1.1.5 Verification will be based on LR’s interpretation of the coastal state Regulations as applicable to the type of unit and its function. Where appropriate, the coastal state Regulations will take precedence over the Classification Rules if considered more stringent.

1.1.6 The verification approval will cover only the standards of design, construction, materials, workmanship, equipment, machinery, systems and installed plant as prescribed by the Regulations. Those aspects concerning operations, personnel equipment and the overall safety philosophy will be the responsibility of the Owner, Operator and/or Duty Holder.

1.1.7 LR can also advise Owners, Operators and/or Duty Holders on safety aspects and carry out risk analyses on their behalf, in order to provide the documentation required in the internal control system as stipulated by the coastal state.

1.2 Existing units

1.2.1 In the case of an existing classed mobile unit or installation which has been built in accordance with the legislation of a coastal state, other than that now required, LR will carry out a comparison with the coastal state Regulations as applicable. Deviations from the required coastal state Regulations which do not achieve an equivalent safety standard will be listed.

1.2.2 When an existing unit is converted or modified, any new modifications, technical equipment or system are to comply with the required coastal state Regulations, as applicable.

1.3 Recognised Codes and Standards

1.3.1 When the coastal state Regulations do not refer to specific Codes or Standards or define specific acceptance criteria, verification approval will be carried out in accordance with the class Rules or, where appropriate, in accordance with internationally recognised Codes and Standards. See Pt 12, Ch 1 Recognised Codes and Standards.

1.3.2 The class Rules and/or recognised Codes and Standards may also be used for verification approvals when they are considered to provide an equivalent standard to the coastal state Regulations or when additional requirements are considered necessary to meet LR’s interpretation of the Regulations.

1.3.3 The mixing of different parts of Codes and Standards is to be avoided.
