In order to eliminate the problems experienced in the systems used in accordance with the Regulation on Waste Collection from Ships and Control of Waste, to improve the systems, and to reduce bureaucracy, Ship Waste Tracking System (GATS) and Blue Card System (MKS) applications were combined under a single roof and developed as the Maritime Waste Application (DAU). If an application is submitted, Mersin Marina works meticulously to keep the ship/yacht and the Mediterranean clean with its wastewater facility service.
