Unitor Introduces Shipboard Polymer Repair System Unitor has introduced a new polymer repair System, which is designed to offer vessel operators the ability to undertake emergency repairs as well as permanent repairs to pipes, all types of mechanical equipment and machinery composites, including non-weldable materials. The pack- age contains well-tested products, and a key component of the system is a 76-page marine maintenance manual, which covers each product and type of repair, using drawings to explain repair procedures. The products in the system are compat- ible with all ferrous and non-fer- rous metals as well as most plas- tics, and reportedly have been suc- cessfully used for permanent repairs. Typical applications for the poly- mer repair system include: emer- gency repairs; situations in which hot work such as welding is not permitted; where the base materi- al is not weldable; where distortion of the base material is unaccept- able; where there is restricted workspace; where specific qualities are required; and where there is a need for non-metal repairs.

Using Micom software, the appa- ratus can perform general arc, C02, MIG and gouging welding. It features self-diagnostics and auto- matic control for maximum effi- ciency, according to the type of welding performed. It also fea- tures remote controls, designed to permit easy change from one type of welding to another.

With the significant price difference between heavy and lighter fuel oils, lower quality, high viscosity oils are commonly used in marine diesel engines. Shipowners are attracted to the less expensive fuels because engine manufacturers have, and continue to successfully develop slow and medium speed diesel engines which can operate on lower grade fuels. Optimizing combustion efficiency while running on lower quality fuels is essential. Failure to do so can result in excessive wear to pis- tons, piston heads, exhaust valves and injectors. To achieve optimum burn, it is necessary to continuous- ly measure and control fuel oil vis- cosity. Viscosity-based control uses direct, continuous measurement of the fuel viscosity immediately after the fuel preheater, with con- tinuous adjustments of the pre- heater temperature to achieve the best viscosity. The key is having a reliable sensor, which CAS offers. Since 1990, dozens of CAS HFO viscometers have been successfully installed on various ships, includ- ing six Sealand Services, Inc. D-9 class vessels. In nearly every installation, the CAS viscometer has replaced an originally installed viscosity sen- sor.
