Full title and description

St NACE SP0607-2007 — Petroleum and natural gas industries — Cathodic protection of pipeline transportation systems — Part 2: Offshore pipelines (ISO 15589-2:2004, modified). This NACE technical standard is a modified adoption of ISO 15589-2 and provides requirements and recommendations for pre-installation surveys, design, materials, equipment, fabrication, installation, commissioning, operation, inspection and maintenance of cathodic protection systems for offshore pipelines.

Abstract

This standard covers cathodic protection (CP) systems for offshore pipeline systems used in the petroleum and natural gas industries. It addresses CP design approaches for galvanic (sacrificial) and impressed-current systems, anode materials and manufacturing, installation and quality control, monitoring and survey procedures, commissioning and operation, and procedures for retrofits or repairs to existing pipelines. The document applies to carbon and stainless steel pipelines in submerged and riser sections up to mean water level.

General information

• Status: Historical / original NACE adoption (2007); later editions and revisions of ISO 15589-2 and subsequent NACE practices have superseded or updated the guidance in practice.
• Publication date: November 5, 2007 (NACE publication of SP0607-2007).
• Publisher: NACE International (National Association of Corrosion Engineers).
• ICS / categories: Petroleum and natural gas industries; pipeline cathodic protection — ICS 75.200 (pipelines) and related corrosion subject headings.
• Edition / version: 1st edition (2007), modified adoption of ISO 15589-2:2004.
• Number of pages: Approximately 87 pages.

Scope

The scope covers cathodic protection requirements and recommendations for offshore pipeline transportation systems used in petroleum and natural gas service. It is applicable to carbon and stainless steel pipelines, including retrofits, modifications and repairs, and to all types of seawater and seabed environments encountered in submerged conditions and on risers up to mean water level. The standard explicitly notes special conditions where CP may be ineffective or partially effective (e.g., elevated temperatures, disbonded coatings, thermal insulating coatings, shielding, bacterial attack or unusual contaminants).

Key topics and requirements

• Pre-installation surveys and site assessment for offshore CP design.
• Design principles for galvanic and impressed-current cathodic protection systems for pipelines.
• Selection, manufacture and quality control of galvanic anodes and impressed-current system components.
• Installation and commissioning procedures, including testing and acceptance criteria.
• Monitoring, inspection, documentation and maintenance of CP systems and surveys (including attenuation and performance testing).
• Guidance for retrofits, repairs, and modifications to existing pipeline CP systems.
• Annex material on design calculations, monitoring methods and interference management.

Typical use and users

Primary users include pipeline design and corrosion engineers, offshore pipeline operators and owners, cathodic protection system designers and suppliers, anode manufacturers, inspection and survey contractors, classification societies, and regulatory or standards committees involved in offshore pipeline integrity and corrosion control. The standard is used as a technical reference during design, procurement, installation, commissioning and maintenance phases.

Related standards

This NACE practice is tied to ISO 15589-2 (the source ISO document, originally 2004 and revised in later editions) and has been incorporated into later NACE practice documents (for example, the ANSI/NACE SP0115 series and later ISO updates). Other related standards address pipeline coatings, onshore CP (ISO 15589-1), materials selection and testing (ISO 21809 series, ISO 13623, and NACE pipeline corrosion documents).

FAQ

Q: What is this standard?

A: St NACE SP0607-2007 is NACE’s modified adoption of ISO 15589-2:2004 providing recommended practices and requirements for cathodic protection of offshore pipeline transportation systems in the petroleum and natural gas industries.

Q: What does it cover?

A: It covers pre-installation surveys, CP system design (galvanic and impressed-current), anode materials and manufacturing, installation and commissioning, monitoring and maintenance, and procedures for retrofits and repairs on offshore pipelines.

Q: Who typically uses it?

A: Pipeline and corrosion engineers, offshore operators, CP system vendors and installers, survey contractors, anode manufacturers, and regulatory or classification bodies.

Q: Is it current or superseded?

A: The 2007 NACE SP0607 edition is an earlier, historical adoption of ISO 15589-2:2004; later revisions of the ISO 15589-2 series and subsequent NACE/ANSI practice documents (for example, the NACE SP0115 series and ISO 15589-2 updates) represent the current references and should be consulted for up-to-date requirements. Check the latest ISO and NACE publications for the most current edition before specifying.

Q: Is it part of a series?

A: Yes — it is part of the broader ISO/NACE pipeline cathodic protection suite (ISO 15589 series: Part 1 for on-land pipelines and Part 2 for offshore pipelines) and sits alongside other NACE pipeline and corrosion standards and recommended practices.

Q: What are the key keywords?

A: Cathodic protection, offshore pipeline, galvanic anode, impressed-current, pipeline integrity, monitoring, commissioning, ISO 15589-2, NACE.
