ISO 16145-5:2014 PDF

Overview

ISO 16145-5:2014 is an international standard developed by the International Organization for Standardization (ISO) that specifies a method for the assessment of coating damages in ships and marine technology. This standard focuses primarily on protective coatings applied to ballast tanks and cargo oil tanks where the International Maritime Organization’s (IMO) Performance Standard for Protective Coatings (PSPC) is enforced. It can also serve as a reference method for assessing coating damages in other maritime areas. The standard supports shipowners, shipyards, coating manufacturers, inspectors, and applicators by providing a clear and consistent damage assessment process aligned with IMO PSPC requirements.

Key Topics

• Scope of Application The standard applies to ballast tanks and cargo oil tanks subject to IMO PSPC regulations and can be used as a guideline for other marine coating applications.

• Assessment of Coating Damages ISO 16145-5 outlines the procedure for evaluating the extent of coating damages based on damage size, location, and overall impact, excluding damages located in specific areas such as erection butts.

• Exclusion of Erection Butt Areas Damage assessment excludes coating damages within erection butt areas and watertight fillets, which are inherent to ship construction and subject to specific allowable ranges.

• Certification of Inspectors Damage assessments must be conducted or confirmed by certified coating inspectors holding qualifications such as NACE Coating Inspector Level 2, FROSIO Inspector Level III, or equivalent certifications, ensuring reliable and standardized evaluations.

• Damage Quantification Methods The standard introduces graphical approximation and percentage calculations for quantifying damaged coating areas in tanks. Annex A provides a practical method for approximate damage area evaluation through graphic techniques.

Applications

ISO 16145-5:2014 is essential in the maritime industry for:

• Shipbuilding and New Construction Ensuring coating damages in ballast and cargo oil tanks are properly assessed during new ship construction to meet IMO and regulatory standards.

• Quality Control and Inspection Providing a standardized framework for coating damage evaluation by certified inspectors helps maintain coating integrity, prevent corrosion, and extend the vessel’s service life.

• Regulatory Compliance Assisting shipowners and operators in complying with international regulations, such as IMO PSPC, which mandate protective coatings and their maintenance for ship safety and environmental protection.

• Maintenance and Repair Planning Accurate assessment of coating damages allows for prioritized maintenance and repair interventions, reducing downtime and repair costs.

• Training and Certification Supporting inspector training programs by defining acceptance criteria and technical requirements for coating damage assessment.

Related Standards

ISO 16145-5:2014 is part of the broader ISO 16145 series dedicated to ships and marine technology protective coatings and inspection methods, including:

• ISO 16145-1: Dedicated seawater ballast tanks
• ISO 16145-2: Void spaces of bulk carriers and oil tankers
• ISO 16145-3: Cargo oil tanks of crude oil tankers
• ISO 16145-4: Automated measuring method for total water-soluble salts

Additionally, ISO 16145-5 references and supports compliance with IMO resolutions such as MSC.215(82) (Performance Standard for Protective Coatings on Ballast Tanks) and MSC.288(87) (Performance Standard for Protective Coatings on Cargo Oil Tanks). The standard also aligns with IACS (International Association of Classification Societies) unified interpretations related to PSPC.
