The Challenges of PSPC

A suppliers perspective

The Challenges of PSPCA suppliers perspective

1. Obtaining information


Test equipment suppliers are not included on

the list of interested parties so rely on:

knowledge of the industry

conferences & papers

customers

1. Obtaining information


2. Standards


IMO PSPC References:

products Visual assessment of surface cleanliness.

For the regulation to prove it achieves what is

This Standard is based on specifications and requirements which intend to

provide a target useful coating life of 15 years, which is considered to be the

time period, from initial application, over which the coating system is intended

to remain in GOOD condition.

then some of the standards referenced will

be 25 years out of date

3. Equivalency


The IMO PSPC has clearly defined acceptance

criteria for alternative systems - section 8.2 and annex 1

What is the equivalency for test equipment?

3. Subjective versus Prescriptive



Although the IMO PSPC allows some leeway

for inspection levels:



Although the IMO PSPC allows some leeway

for inspection levels:

The surface temperature of steel, the relative humidity and the dew point

shall be measured and recorded before the blasting process starts and at

times of sudden changes in weather.

Any oil, grease or other visible contamination shall be removed.

On completion of blasting and cleaning and prior to the application of the first

coat of the system, the steel surface shall be tested for levels of remaining

soluble salts in at least one location per block.

The surface temperature, the relative humidity and the dew point shall be

monitored and recorded during the coating application and curing.



Even where IMO PSPC is prescriptive



Gauges have to be designed to be flexible




From individual spot checks




From individual spot checks

to automated data logging


4. What is in the CTF?



the IMO PSPC clearly indicates what is to be

included in the CTF - but:





does not state the amount of information needed

Do all the individual readings need to be recorded or the summary?

Are photographs of the surface condition required or not necessary?





does not state the amount of information needed

Do all the individual readings need to be recorded or the summary?

Are photographs of the surface condition required or not necessary?

or define the format of the CTF

Will each Classification Society require different layouts?

How will this be accepted around the world?


Summary

Although Elcometer as a Global Organisation

is very proactive in the industry, inspection

equipment suppliers need to be included as

early as possible:

Allowing seamless integration of gauges & software

Allowing improvements in gauge technology to be

included automatically

Reducing the time to bring new products to market

reducing costs and time for the shipyards earlier


Thank you
