DNV Offshore Codes consist of a three level hierarchy of documents:
— Offshore Service Specifications. Provide principles and procedures of DNV classification, certification, verification and consultancy services.
— Offshore Standards. Provide technical provisions and acceptance criteria for general use by the offshore industry as well as the technical basis for DNV offshore services.
— Recommended Practices. Provide proven technology and sound engineering practice as well as guidance for the higher level Offshore Service Specifications and Offshore Standards.
DNV Offshore Codes are offered within the following areas:
- Qualification, Quality and Safety Methodology
- Materials Technology
- Special Facilities
- Pipelines and Risers
- Asset Operation
A 100 Introduction
101 This standard contains requirements for fabrication and testing of offshore structures.
A 200 Objective
201 The objectives of this standard are to:
— provide an internationally acceptable standard to ensure the quality of all welding operations used in offshore fabrication, through identifying appropriate welding procedures, welder qualifications and test methods
— serve as a technical reference document in contractual matters between purchaser and contractor
— serve as guideline for designer, purchaser and contractor
— specify minimum requirements for welding operations
subject to DNV certification and classification.
FABRICATION AND TOLERANCES (includes pressure vessels and air receivers)
A 100 Objective and scope
101 This section gives requirements for fabrication and tolerances
of offshore structures.
B. Fabrication Planning
B 100 General
101 As a prerequisite for fabrication, procedures, inspection and test plans and work instructions for execution and control of fabrication activities shall be established. The purpose of the procedures and work instruction shall be:
— to provide instructions and information regarding the requirements for and the principles of the work execution
— to identify and document the responsibilities and plans for the work execution in accordance with the project requirements
— to provide information to the purchaser on how the work is executed and controlled
— to identify applicable procedures, test plans, work instructions, acceptance criteria, hold points and documents to be generated
— to serve as basis for quality audits.
102 Relevant procedures, including information of pre-assembled items and the sequence of fabricating the parts into structure, shall be prepared.
B 200 Quality system and workmanship (includes pressure vessels and air receivers)
201 Fabrication of structural members shall have a documented and implemented quality system according to ISO 9001 or equivalent. The extent of the quality management system shall be dependent on the size and type of the organisation, complexity and interaction of the processes and competence of personnel.
202 Workmanship shall be in accordance with E following written procedures agreed upon.
203 All work shall be skilfully and carefully executed with adequate control by the contractor. All faults and deficiencies shall be corrected before the material is coated with paints, cement or similar. Repair work of significant extent shall be demonstrated as acceptable to the purchaser.
204 Prior to commencement of the work the contractor shall submit a plan for NDT, NDT procedures and documents for NDT inspectors’ certification for acceptance by the purchaser. The programme shall contain information and documents for planning, controlling, reporting etc. Acceptance criteria for NDT shall be accepted by the purchaser if they are not specified in relevant documents.
C 100 General
101 Inspection shall be carried out in accordance with accepted inspection and test plans to confirm that work is carried out in accordance with established project procedures and plans such that all project requirements are complied with to the satisfaction of the purchaser.
The inspection shall cover items such as:
— correct identification and documentation and use of materials
— qualification and acceptance of fabrication procedures and personnel
— inspection of preparatory work (assembly, fit-up form work, reinforcement etc.)
— welding inspection
— inspection of fabrication work for compliance with specifications and procedures
— witnessing NDT, control and testing
— inspection of repairs
— inspection of corrosion protection systems
— ensure functionality of examination or testing equipment
and of recording and/or measuring devices vital for correct functioning of equipment and machinery used in fabrication. 102 Due consideration shall be given to the access and the time required for adequate inspection during fabrication.
103 High non-conformance rates in execution of the work or in the product itself shall call for special considerations. Such special considerations may include, but not be limited to, increased inspection, re-qualification of personnel or other agreed remedial actions.
104 Inspectors shall be qualified according to a recognised scheme and shall be able to provide documentation of proficiency.
