DAMEN COMPANIES HELP SHIPS GO GREEN 
Damen Green Solutions and Damen Shiprepair & Conversion (DSC) have combined skill sets to help ship owners comply with new environmental regulations. 
Last year the International Maritime Orga­nization ratified the Ballast Water Management Convention mandating ballast water treatment. Damen Green Solutions assists ship owners in se­lecting the best treatment system for their needs from nearly 70 different manufacturers. Once a system is chosen, DSC performs the project man­agement and execution. 
Further providing green solutions, DSC can install exhaust after-treatment systems or scrub­bers to provide cleaner emissions and can con­vert engines to allow for the use of Liquefied Natural Gas (LNG) which has less NOx, Sox and particulate materials, making it a cleaner burning fuel. 
For these projects Damen Green Solutions provides information and guidance to owners, and shares best management practices such as regular propeller cleaning, and use of antifouling paint. Together the companies provide a one-stop shop for ships looking to go green. 
 
ALLU PATENTS NEW DRUM ASSEMBLY CONSTRUCTION 
ALLU has patented its TS™ drum assem­bly construction, which configures screening blades that spin between screening combs. 
The new assembly is manufactured for the existing ALLU D-series material processor bucket frames. By repositioning the combs, different fragment sizes can be achieved al­lowing for the performance of multiple jobs in one unit. The machine works in wet and dry materials without clogging, and because the combs carry most of the material weight, wear and tear on the drums and bearings is reduced. 
The TS drums come with standard blades for screening applications and axe blades for crushing or shredding. The blades are available in sizes 0.63/1.26 in (16/32 mm), 0.98/1.97 in (25/50 mm) and 1.38 in (35 mm). The TS assembly includes seven dif­ferent models for 17.6- to 49.6-ton (16- to 45-metric ton) excavators and 7.7- to 33-ton (7- to 30-metric ton) wheel loaders.
