Marine Coatings Review — International (continued from page 39) time in drydock. HISOL is totally compatible with existing Inters- mooth SPC systems. The new coating is available in two forms: HISOL 200 series is a slow-polishing, smoothing copoly- mer recommended for application to all vessels over 15,000 dwt, and those operating permanently in warm waters. HISOL 900 series is a faster-polishing, smoothing co- polymer than the 200 series, de- signed for vessels under 15,000 dwt, or low-activity vessels oper- ating permanently in a severe fouling environment. It is particu- larly suited to vessels entering lay-up, allowing them to re-enter service without the need for sub- stantial hull cleaning either afloat or in drydock. The second antifouling intro- duced, Interswift, is an eroding, polishing copolymer that fills the performance gap between tradi- tional antifoulings and HISOL. In- terswift, which supersedes Inter- speed Special, achieves up to 50 percent savings in application costs, as one coat is used instead of two. Greater Efficiency on Shallow Water Routes Ultra Shallow Draft Vessel When applied over approved sub- strates, a single 6-mil coat will give in-service protection for 24 months. Such a specification costs little more than a two-coat traditional high-performance antifouling scheme when the reduction in la- bor costs are accounted for. Alter- natively, two coats of 4 mils each will protect the underwater hull for 30 months. A third new product range has been introduced, Intershield EG series, abrasion-resistant coatings. Intershield has been engineered to reduce removal of the anticorro- sive coating, which is the major cause of corrosion. Feedback from a large number of shipowners in- dicated that once mechanical dam- age exceeds three percent scat- tered over a given area, it is considered a serious problem re- quiring extensive and costly repair. With twice the impact resis- tance and two to three times the resistance to erosive wear, Inter- shield's benefits include: reduced maintenance costs through im- proved protection against mechan- ical damage and reduced corro- sion; improved cosmetic appearance; and minimization of mechanical damage sustained by the underwater hull, contributing to a smooth hull and fuel savings when used with Intersmooth HISOL. International Paint has intro- duced these three new product lines as part of an ongoing world- wide program to offer shipowners cost-effective, high-performance marine coatings that will save time and money in both services and at drydock intervals. USDVs are applicable for all types of vessels intended for service between shallow ports. Plant transport ships, tankers, bulk carriers, chemical carriers, RO/RO ships, container vessels, and liquefied gas carriers, are just some of the possibilities.

Typical applications include: container rust prevention; various marine applications, in- cluding fresh and salt water bal- last tanks, chain lockers, voids, and cofferdams; protection of over- seas shipments; offshore drilling rigs; and many others. These finishes are a specially blended formulation of an inor- ganic-organic complex that ob- tains its unique, virtually impen- etrable moisture barrier by formulation of highly polarized microscopic platelets lying parallel to the coated surface. This multi- layered effect, when combined with other highly resistant components included in Cortec finishes, results in one of the most durable coat- ings of its type currently in the field. These products are not lanolin- We have now solved all the technical problems inherent to shallow draft vessels, thanks to our new design utilizing the "dual engine, dual shaft" concept. Mitsubishi can provide USDVs in any dimensions up to a max. B/d ratio of 6.5 and a min. L/B ratio of 3.5.
