Objective

This document describes the pipe mill qualification service of DNV. This service is based on the requirements to line pipe manufacture in DNV-OS-F101.

Following the same principles, the qualification of coating application can be carried out according to DNV-RP-F106.

DNV deliverable

The key DNV deliverable is a Statement of Compliance (SoC) upon successful completion of the qualification program. The SoC is valid on the date of issuance, and lists the parameters (ID, WT, steel grade, coating system, design temperature etc) that define the scope of the qualification.

DNV shall also issue a Verification Report, where all DNV activities are summarised. The conclusion – qualification successful or not – shall be presented. In addition, DNV shall give a general assessment of the pipe mill/coating yard and the qualification project. This assessment is detailed in Site Visit Reports.

Motivation

The market for offshore pipelines demands rigorous quality. The required quality for offshore line pipe is set by leading standards such as DNV-OS-F101. DNV provides solutions to assist pipe mills in documenting that their product meets the requirements of DNV-OS-F101.

There are several reasons for a pipe mill to carry out a DNV qualification:

- pre-qualification for a pipeline project

- the client requires a SoC before the pipe mill can enter the tender phase
