Hempel's Cargo Barriers, a range of specialized coatings for the protection of cargoes/cargo tanks, has been well-received in the marketplace since it was launched in March 1987.
During that period, the company received 80 enquiries—37 for newbuildings and 43 for maintenance contracts. Of this total, 12 projects were not proceeded with by the owner; 21 were awarded to Hempel's (eight newbuildings, 13 maintenance); 16 were placed elsewhere, and 31 are pending awaiting a decision.
The 21 tank coatings contracts awarded to Hempel's were placed by owners in the USA, U.K., Norway, Denmark, the Netherlands, Greece, Singapore and Japan.
Cargo Barriers constitute a total of six organic and inorganic coatings plus two shop primers, which generate 10 different coatings systems, all of which are set out in an easy-toread systemized selection chart.
In addition, the Range is backed by a computerized Cargo Protection Guide, which provides owners with detailed "tailor-made" information.

As a result, the number of revenue-earning voyages completed by the vessel is more than 40 percent greater than that of vessels treated with other coatings systems. The Coralwater's substantial improvement in performance is primarily due to faster cleaning and drying of the cargo tanks, which provides
