Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents" drafting.

This document is part 3 of GB/T 41066 "Offshore Oil Semi-submersible Drilling Platforms for Oil and Gas Drilling Equipment".

GB/T 41066 has issued the following parts.

--- Part 1: Functional configuration and design;

--- Part 2: Construction, installation and commissioning acceptance;

--- Part 3: Operation and inspection.

Introduction

Semi-submersible drilling platform is the mainstream deepwater drilling equipment in the world. In recent years, my country has made great progress in the R&D and manufacturing of offshore drilling equipment.

Great progress has been made, and the independent design and construction of large-scale medium and deep water oil and gas equipment has been basically realized, and an echelon series has been formed in terms of equipment scale. To ensure that offshore drilling equipment has developed in an orderly and healthy manner. Offshore oil fixed platform module drilling rigs, offshore oil jack-up drilling platforms, and offshore rock drilling rigs have been established.

Oil semi-submersible drilling platform as the main line of the standard system. In this standard system, "offshore oil semi-submersible drilling platform" focuses on the It is planned to establish a quality control technology system covering the entire life cycle of the platform to provide technical support for the high-quality development of offshore oil and gas resources.

GB/T 41066 "Oil and Natural Gas Drilling Equipment for Offshore Oil Semi-submersible Drilling Platforms" consists of three parts.

--- Part 1: Functional configuration and design. The purpose is to standardize the overall configuration, equipment selection and design of semi-submersible drilling platforms.

--- Part 2: Construction, installation and commissioning acceptance. The purpose is to standardize the semi-submersible drilling platform construction and equipment installation, commissioning methods, Acceptance criteria.

--- Part 3: Operation and inspection. The purpose is to standardize the certification, operation and inspection requirements of semi-submersible drilling platforms after they are put into operation.

This document provides technical basis for platform operation and operation inspection, so that it has good safety operation guidelines and operation inspection methods.

1 Scope

This document specifies the operation and inspection requirements for offshore oil semi-submersible drilling platforms after delivery.

This document applies to the operation and inspection of offshore oil semi-submersible drilling platforms (hereinafter referred to as "platforms").
