Advanced Polymer Coatings’ MarineLine® 784 cargo tank coating system, already considered the pre-eminent coating for chemical tankers, is becoming an important factor in new transport markets. “There is a growing market need for product tankers to carry the expanding group of cargoes such as clean petroleum products (CPPs), bio fuels, vegetable oils, and methanol,” says Donald J. Keehan, Chairman of Advanced Polymer Coatings. “In addition, new regulations for coating tankers carrying oil and dirty petroleum products (DPPs) has also increased interest in MarineLine® for these uses.

To date, MarineLine® 784 has been used on more than 300 chemical tankers worldwide handling a wide range of aggressive chemical cargoes. MarineLine® 784 uses forced hot air heat to cure its coating. This creates a nearly-impermeable coating barrier, thus ensuring product purity from port to port. The ship can carry any cargo immediately after leaving the shipyard, an added bonus.

A key benefit of MarineLine®and its extremely smooth and hard surface is that the tank cleaning process goes faster. Because the coating is virtually absorbent-free with low surface energy, less cleaning chemicals are needed, thus less slops are created. There are also fewer limitations than conventional coatings and stainless steel tanks. This gives the shipowner the opportunity to carry a wide range of profitable cargoes without worrying about the previous cargo residue contaminating the next cargo. Mr. Keehan says that since its inception, MarineLine® has never had an insurance claim made regarding purity, a testimony to the ease of tank cleaning and non-absorbtion of the cargoes carried.

MarineLine® 784 offers much better performance and versatility than conventional phenolic epoxy or zinc silicate linings, and now, it will be at a cost comparable to conventional coatings. “The reason we have been able to lower our costs to customers is that within the past year, APC has revised and streamlined its polymer manufacturing operation,” according to Mr. Keehan. “Previously we employed outside chemical companies to toll-manufacture certain elements of the polymer that serve as a mainstay in the manufacturing of the MarineLine® coating. Now these various tasks are done in-house, thus reducing our cost exposure. This will now enable more shipowners and shipyards to specify MarineLine as the product of choice. We have taken a very competitive pricing stance versus other coatings, while providing a superior product.” MarineLine® 784 has been traditionally offered in grey topcoat colour. Starting this year, the company will also offer an optional ivory colour topcoat in a gloss finish.
