Notes - Brick Company England
1986 M.V. CALLIOPE MARU OF JAPAN SHIPPING LINE LTD.Cotmalco Ltd. the world's largest aluminum company, have developed a A$l00 million Kaolin mining operation in Queensland, Australia. The primary market for supply to the paper industry is Japan, who use Kaolin for high speed coating applications. In order to lift an initial number of cargoes of about 23,000 tons each of Kaolin, the M.V. Calliope Maro of Japan Shipping Line Ltd., self-sustained bulk-carrier was selected for this arduous operation.
PREVIOUS PAINT SYSTEMS HAD FAILED - Selection of New Paint System
The requirements for absolute cleanliness of a vessel's hold, hatches and grabs are extremely stringent, and even discovery of minor rust scale and/or paint peeling (causing contamination of cargo) will result in outright rejection of the cargo. Superior protection after grit blasting (SA 2.5 - new copper slag grit only to be used) of bulkheads, hatch coamings and other areas, with a paint system which showed high resistance to impact (grab damage) ease of application and drying, non-peeling and break line characteristics. General compatibility with all other conventional marine paints. Ease of superior ability to touch up after damage on an on-going basis.
IT WAS ON THESE PARAMETERS THAT WE DECIDED TO SELECT NEUTRA RUSTŪ HIGH PERFORMANCE COATINGS OF THE TL BARRIER AND 661 TYPES RESPECTIVELY IN ORDER TO ENSURE MAXIMUM PROTECTION AGAINST CORROSION DEVELOPMENT
It will be your sole responsibility to ensure that the work will be finished to a standard which will justify the very high cost that our clients have agreed to cover in order to ensure that the vessel will be in superior condition to accept Kaolin and to maintain that condition for the next twelve months.
We wish you well in your task and express the hope that our expectations, which formed the basis for selection of Neutra Rust High Performance Coating will be fulfilled in every respect.
PAINT INSPECTION REPORT 1987
3 colour paint systems each coat 60m/2.3 mils DFT.
Total used l80m/7, mils DFT.
UNDERSIDE OF HATCH COVER
The general condition of the hatch cover underside, was excellent.
COAMING
The seal bar was in very good condition, as was the channel between the top edge of the hold side plating and the seal bar.
HOLD SIDES (Att. Port, Forward, Starboard.)
There was one small area of heavy damage on the forward bulkhead at the 3 metre level, which appears to have been caused by the grab or the bulldozer blade. As previously stated, in only a few small areas was the Neutra RustŪ TL BARRIER Grey paint film penetrated or broken.
HOLD ACCESS
The hold access ways, ladders, and closing plates were inspected and found to be in good condition.
TANK TOP - Undamaged by caterpillar track bulldozer Remarkable!
The tank top had sustained remarkably little damage considering the fact that a 6m3 grab and a steel caterpillar track bulldozer were used to scrape up the cargo during the discharge, while the steel tracks had damaged the paint work in many areas of the tank top. Penetration down to the bare metal was minimal. The visual condition at inspection proved that NEUTRA RUSTŪ TL BARRIER was highly resistant to impact and abrasion. It is worth noting that what damage had occurred was quite easily and quickly repaired with NEUTRA RUSTŪ TL BARRIER.
IT IS RECOMMENDED THEREFORE, THAT NEUTRA RUSTŪ COATINGS ARE USED FOR FUTURE HOLD PAINTING. PARTICULARLY IN DAMAGE-PRONE AREAS AS HOLD SIDES AND TANK TOPS.
