Analysis on Feasibility Study of PE Material Buoys for Vietnam Inland Waterways and Maritime Channels

In the modern life, marine structures such as projects for exploiting inland waterways, navigational channels, and transportation types are developing more and more. The research of materials technology for these projects on channels is not only fast but also requires high precision. As a result, aids to navigation play an important role in maritime safety for all marine routes of Vietnam. One of them is buoys which have been improving significantly not only in Vietnam but also around the world. The purpose of this article is given the new improving aids to navigation in modern life. Instead of using steel buoys, new technology buoys will be used for Vietnam maritime channels with the priority of long age and convenient for authorities. At present, new technology buoys latest replacement of steel buoys to low-maintenance quality PE buoys have been installed at Mekong River Commission–Lao PDR, Cambodia, and Vietnam RWS (Lighthouse Authorities)–The Netherlands Port Of Rotterdam–The Netherlands, Maritime Office–Poland DAB VLOOT–Belgium, Nigerian Inland Waterways Administration and Nigerian Port Authorities–Nigeria Australian Maritime Safety Authority–Australia Arabian Maritime and Navigation Aids Services–Oman. In fact, new technology buoys are polyethylene buoys which are rotational molding by a pre-determined quantity of polyethylene powder pre-compounded of required color. Thus, in process of manufacturing PE buoys, rotational molding is a method for manufacturing hollow plastic products with all dimension and shape.
