The 17,500 DWT oil tanker project for a cargo pump package and engine room for two sets of ships. The main advantage of the pumps used is their high efficiency in various operational conditions, such as the Allweiler CNH-B 200-500 G W20 horizontal centrifugal pump for cargo oil transfer, which has a capacity of up to 600 m³/h with an efficiency of 70.4%. These pumps are designed to handle fuel oil with various viscosity levels, and operating temperatures of 30°C, and meet the specific needs of oil tankers operating in demanding sea conditions.
