ABSTRACT:
A Portable Dry Dock (PDD) system designed for commercial servicing of recreational vessels (RVs) in inland waterways (IW). This PDD is disassembled and transported from one IW to another. This PDD was designed specifically to improve the efficiency in the most typical maintenance jobs in RVs. The convenient layout of the equipment and the closed environment of the PDD reduce the execution time and improve the working conditions. The isolated environment created by the superstructure, deck and roof of the PDD significantly reduces the environmental impact. The isolated environment inside the PDD is controlled in temperature and humidity. The air filtering and waste water collection systems remove dust and other substances coming from the operation, stopping pollutants from getting into the IW.
