The requirement very much depends on the type of vessel and

more so the liquids being carried.

Cleaning How, and where to get the info

- how to clean who are the experts- hot cleaning water vs cold wall effct

- organic coating vs inorganic coating

- absorption vs desorption

BUT BEFORE THAT..


9/52




Paint challenges Blisters; detachments; pit corrosion

- too limited time for cleaning / ventilation

- tank top of COT: Sulphur Reducing Bacteria

- ageing of coating deckhead

- pit corrosion on tank top

- fast deterioration of zinc silicate

BUT BEFORE THAT..

Training Riga (done in the past November 2010)

- under discussion with Neil Barnes to organise cargo tankcoating training for Riga office in the near future

Substantially improved resistance to mud cracking

Mud-crack Resistance over 200 microns

Negligible spray dust

Relatively Smooth surface

Easier to cleaning in between cargoes

Chemical Resistance

Looking at the chemical resistance of the typical cargoes shipped

in Tankguard Special Ultra coated tanks:- Palm Oil no limitations- Vegoils in general no limitations- Oleochemicals no limitations

- CPP no limitations- Chemicals closer look required, but widest chemicalresistance for a phenolic epoxyor alike in themarket

Bio-fuels

- Bio fuel addition of ethanol to petrol

Resistance to ethanol(may) require(s) aphenolic epoxyesp. forlong term performance of the coating system.

Bio-fuels

- Bio diesel addition ofFAME to diesel

The addition ofFAMEto diesel. This is basically not a challenge,provided that the FFA-% is not too high (but this is probably not allowedwithin the specifications).

This process is called transesterfication and is predominantlydone to lower the viscosity.

Chemical Resistance

Often the main deciding factor when selecting a tank coating.

Extensive exposure testing has been performed- comparison with bench mark product- wide range of curing conditions including varying post-curing- a long list of chemicals tested- cyclic testing

Adhesion, blisters,discolouration, etc have been

evaluated

Chemical Resistance required

----- Far East / Arab Gulf & Red Sea

Chemicals; CCP; Palm OilChemicals depends on type of chemicals, but would suggestTankguard Special Ultra

CPP Tankguard HB would suffice

Palm Oil depending on the pretreatment, resulting in a certain level of FFA, probably

Tankguard Special Ultra would be best suggested

For 4 chemicals Tankguard Special Ultra doesnot have sufficient chemical resistance

However, feedback from owner:1. Based on the certificate of fitness aceticacid, nitric acidand formic acidshall onlybe loaded in STAINLESS STEEL tanks

2. Most suppliers/receivers prefer STAINLESS

STEEL tanks when shippingphenol

Certain owners active the SEA region are typically having the requirement

out-bound: Palm Oilproducts, including Palm Fatty Acid Distillates

in-bound: methyl alcohol; MEG; Caustic Soda; pygas; luboil & others

In case the cargo tanks are coated with Tankguard Special Ultra, there areno limitations from the coatings point of view.

Pre-wash after carriage of aggressivecargoes and bio-fuels:

this can be accepted for all cargoesthat require this pre-wash

This includes executing pre-wash

after carriage ofmethanol.

Note: the pre-wash procedure needs to be discussed.



47/52


In general in cargo tank coating, care regarding subsequent cargoes,since risk of:

- Cargo contamination

- Negative effect of sequence of chemicals

But these risks are not applicable when back-2-back shipment.Hence, any cargo can be shipped back-2-back.
