The unforeseen importance of a clean onboard environment

Despite how simple it may seem, good housekeeping and cleanliness are some of the biggest factors that contribute to safety in a vessel.


Having a clean engine room or deck is not only nice to have but also important for the crew to help them do their job safely.


Clean machinery spaces allow one to detect leaks and other defects that may potentially lead to bigger accidents. Moreover, regular cleaning preserves the value of the ship and ensures compliance in today’s regulatory environment.

The reduction of any one of the factors can be compensated by increasing other factors. Therefore, a smart combination of the aforementioned elements can give the desired cleaning result. As a seafarer, you would want to minimise the effort and time spent on cleaning tasks, and there is always a limitation working with high temperatures. As a result, choosing the right chemicals may end up being the most critical factor.

What is the right chemical?

Does it really matter as to what kind of chemical we use for cleaning on ships?

Yes it does!

The ship is a complex ecosystem with different machineries and applications. A chemical used for cleaning a certain equipment in the engine room might not work as well for cleaning on deck or, in worse cases, may do more harm than good.

Moreover, in case of engine room cleaning, the chemicals can have a significant impact on the performance of Oily Water Separator; chemicals that form a very stable emulsion will have a detrimental effect on the oily water separation.

Therefore, it is imperative that a ship’s crew use chemicals from a trusted supplier who, along with the chemicals, can also provide the right support in using the chemicals in the correct manner and achieve the desired results.
