The unique and patented Port Feeder Barge (PFB) can be considered as a 'green logistic innovation' for ports. This new type of harbour vessel has been already designed in detail as a self-propelled and self-sustained container pontoon of double ended configuration (capacity: 168 TEU). The PFB can be employed in various business fields: shifting the container haulage within and around ports (between the various container facilities) from road to waterway as well as acting as a floating terminal for medium sized container vessels and inland container barges or a combination thereof. The PFB can be easily integrated into the container logistics within any port. In congested ports or ports with limited water depth or insufficient container handling capability it can help to improve container handling much quicker and cheaper than any infrastructure measurement.
