Hempel Brochure on Imo - Pspc

The IMO Performance Standard for Protective Coatings (PSPC)New ballast tank regulations for newbuildings

All you need to know about…

The International Maritime Organization (IMO) is the specialist United Nations agency tasked with improving maritime safety and preventing pollution from ships.

On 8 December 2006, the IMO adopted the new Performance Standard for Protective Coatings (PSPC), as resolution MSC.215(82). This important new standard will also be included in the International Convention on Safety of Life at Sea (the SOLAS Convention).

The PSPC is intended to improve the safety at sea by reducing the corrosion encountered in steel ships, and applies specifically to the protective coatings used for dedicated seawater ballast tanks in all types of ships, and also in the double-side skin spaces of bulk carriers.

Hempel – the most effective way to protect your investment

The aim of the PSPCThe aim of the new standard is to improve safety at sea by avoiding the effects of corrosion, thus enhancing the structural integrity of the vessels as a whole. In specific terms, this involves a target of 15-year useful coating life for ballast tanks classified as being in good condition, according to the definition used by the International Association of Classification Societies (IACS).

The scope of the PSPCThe PSPC applies to newbuildings, and covers protection of the water ballast tanks in all types of ships of 500 gross tonnage and more as well as double-side skin spaces in bulk carriers of 150 metres or more in length.

When does the PSPC come into force?The PSPC enters into force for all shipbuilding contracts placed on or after 1 July 2008. If there is no building contract, it applies to all keels laid from 1 January 2009 onwards. It will then apply to all vessels delivered from 1 January 2012 onwards. It will be mandatory, and an amendment to SOLAS regulations II-1/3-2 and XII/6.

PSPC already applies to the ballast tanks and double-side skin spaces of tankers and bulk carriers built in accordance with Common Structure Rules (CSR) since 8 December 2006 – the date on which the PSPC standard was adopted.

What does PSPC cover?The PSPC sets out requirements for improved procedures and better quality control via increased inspection requirements at all stages within the following three main areas briefly described below.

Surface preparation (primary and secondary), including requirements to: Profile Cleanliness Shop primer

Coating applicationwith requirements that include: Surface preparation in all stages Dry film thickness (DFT) Coating advisers must have FROSIO or NACE certification

Coating qualityincluding requirements regarding: Type Pre-qualification Specification

Overall, there are significantly increased demand for documentation of the entire coating process, right from the raw steel plates to the final coating system. These must be compiled into a Coating Technical File (CTF), which is to be kept on board and maintained throughout the lifetime of the ship.

See the last two pages for a summary description of specific PSPC requirements.

How will PSPC affect shipowners?Shipowners will encounter: The benefits of vessels of higher quality Lower maintenance costs Better retention of investment value Additional costs at newbuilding stage to meet PSPC inspection criteria A need for better documentation of the maintenance processes associated with water ballast tank coatings

That paint specifications for newbuildings need to comply with PSPC That a CTF is to be maintained and kept on board the ship

How will PSPC affect shipyards?Shipyards might have to consider new production procedures and will encounter significantly increased demand for documentation, in order to comply with all PSPC requirements. This will result in: Extra construction time and slower throughput A need to have or train more staff to FROSIO or NACE certification to do inspections Possible investments in new facilities and additional manpower A significantly higher level of documentation required with regards to the selection, application and inspection of ballast tank coatings

Fewer options left available regarding shop primer, ballast tank coating systems and dry film thicknesses

A requirement that all inspection data – from raw steel to final coating – are both retrievable and auditable and made available in the CTF

The need to take responsibility for preparing the CTF

How will PSPC affect coating manufacturers?Coating manufacturers will encounter: A greater need for testing and documentation Increased requirements and costs for obtaining type approvals for water ballast tank coating systems from external test laboratories

Requirements to participate in preparing the CTF The need to modify product data sheets to conform with the PSPC Requirements to specify the maintenance plan to sustain a target of 15-year useful coating life for the coating system in question

Greater demand for FROSIO or NACE certified personnel to carry out the required inspection work

Please consult your local Hempel sales office or www.hempel.com for more information about PSPC and how Hempel can help you protect your vessel in the most effective way possible.

Surface preparation Blasting to Sa 2½ with profiles between 30-75 µm Soluble salts must be removed to less than 50 mg/m2 sodium chloride (lower than the residue left by a normal fingerprint)

Shop primer must be zinc silicate-based (or equivalent) and application and compatibility with coating system must be documented. If not, at least 70% of intact shop primer must be cleaned to Sa 2 All sharp edges must be rounded to a radius of 2 mm or more Visible dust must be removed There must not be any oil contamination present Erection joints must be prepared to St 3 or Sa 2. Areas with rust and damaged coating must be blasted to Sa 2½, if these constitute more than 2% of the total surface area of the tank

Coating inspection

Coating advisers responsible for inspections must be certified to FROSIO Level III (Red) or NACE Level II or equivalent.

Inspections must include (but are not limited to): Surface preparation for all stages, including surface conditions that include temperature, relative humidity, dew point, salts, oil, grease and other contamination

For primary surface preparation; Confirmation of the quality and thickness of the shop primer and its subsequent curing

For block assembly and erection; Visual inspection and measurements of dry film thickness (DFT)

Summary of specific PSPC requirements

Coating system Coating must be an epoxy-based system (or some other system with performance that complies with test procedures) Use of a multi-coat system that must involve contrasting colours Top coat must be light in colour to ease inspection Pre-qualified coating systems must have a B1 rating (DNV Ballast tank simulation test) and/or 5 years in-service life in GOOD condition (according to IACS)

2 full coats and 1–2 stripe coats Minimum Nominal Dry Film Thickness (NDFT) must be 320 µm with the 90/10 rule

Compatibility with zinc silicate shop primer must be documented

CTF (Coating Technical File) must include as minimum Statement of compliance or type approval for the coating system Copy of the Technical Data Sheet for the coating system The shipyard’s work records regarding application of the coating Procedures for the inspection and repair of the particular coating system used A coating log provided by the coating inspector, stating that the coating was applied in accordance with specifications and to the satisfaction of the coating supplier

Documentation of the shipyard’s verified inspection, featuring the completion date, inspection results, any remarks and the relevant signatures

Details about any maintenance and repair of the coating during its service life
