Which method is commonly used to ensure that no residual oil remains after the cargo transfer?

• A. Pumping out with auxiliary pumps
• B. Stripping to one tank
• C. Manual cleaning
• D. Rinsing with seawater

Answer: (B)

Stripping to one tank is a widely utilized method to ensure that no residual oil remains after a cargo transfer. This process involves using pumps to remove as much remaining oil as possible from the cargo tanks and transferring it into a designated stripping tank. This approach is effective in achieving low residual volumes, which is crucial for preventing contamination and ensuring compliance with environmental regulations. By focusing on a single tank during the stripping process, crews can maximize the efficiency of oil removal, minimizing the amount of product left behind. This method is particularly important in the operation of tankers, as even small quantities of residual oil can lead to significant pollution if they are not properly managed. While other methods like pumping out with auxiliary pumps or manual cleaning can also be part of the cargo handling process, they may not achieve the same level of efficiency in removing residual cargo. Rinsing with seawater can sometimes be used to further clean tanks, but it is generally not considered the primary method for ensuring no residual oil remains, as it can introduce contamination issues or complicate the subsequent cargo operations.
