Since then, de- tailed performance analysis onboard the VLCC MV Ramlah has reportedly proven the relative fuel savings and emis- sions reductions. The analysis covered the whole docking period prior to the ap- plication of the Intersleek 700 system (the previous 60 months) and the on- going performance after (up to 54 months to date). The results demonstrate an over- all 6.4% improvement in fuel efficiency which translates into a saving of more than 6,500 tons, equivalent to around $3.2 million at $500 a ton. www.international-marine.com ComCor Tech ComCor Tech has grown to provide tank cleaning, surface preparation, and coating services to the commercial ma- rine and cruise ship industries. ComCor Tech was formed in 1987 to offer serv- ices and products involved with corrosion and combustion technology. It has grown to provide tank cleaning, surface preparation, and coating services to the commercial marine and cruise ship industries. Many know Com- Cor Tech for the blasting and coating work. In the process of cleaning surfaces prior to blasting the company has devel- oped procedures for cleaning and gas freeing areas that are designed to be cost effective to vessel owners. Services Com- Cor Tech provides includes: Clean for regulatory/ship inspection or gas free for hot work; Oil, sludge, galley and laundry tanks; Surface preparation and recoating of potable water tanks; and much more. www.comcortech.com Ecospeed Underwater Hull Coating When a 294m cruise vessel came into drydock in the Bahamas last month after sailing with Ecospeed for two years, less than 1% of the underwater hull needed touch ups and no new paint layers were required on the rest of the underwater hull. As a consequence, the technical op- erations that needed to be carried out on the vessel were very easy to plan because no repaint needed to be added to the schedule. Moreover, the vessel could leave drydock earlier than would have been the case if an extensive repaint had been required. Marine consultant Mike Novak, who previously spent 10 years as vice president of marine operations at HAL, noted that he could clearly see that the required touch ups involved only 1% of the total surface. With all coating sys- tems, a vessel's AHR (average hull rough- ness) will gradually increase due to the buildup of paint layers and the general deterioration of the paint system, result- ing in increased fuel consumption. Dalseide Shipping Dalseide Shipping Services, developed a rust-removing system more than 30 years ago, machines that are based on a patented rotating chain link system that provides more than 200,000 blows per minute depending on the machines size. Rustibus machines have a capacity of ap- proximately 200 sq. ft./hr. to 300 sq. ft./hr. Their latest machine is the electric hand tool, which is ideal for spot scaling and is several times faster than any known equipment on the marked. This is a heavy-duty scaling machine for small horizontal and vertical areas. www.rustibus.com
