Singapore has joined the list of ports that will ban the use of open loop scrubbers in their waters. Exhaust gas cleaning systems (EGCS) – more commonly referred to as scrubbers are an accepted equivalent measure in complying with the IMO 2020 global sulphur cap.

The use of scrubbers has split the shipping industry. With about 15 months to go, the shipping industry is broadly split into two camps, either to burn low-sulphur fuel or install a scrubber system.

But an increasing number of ports around the world are looking at the impact of scrubber use in their waters. With the discharge of wash water into the sea, open-loop scrubbers are seen by  some as simply transferring the sulphur pollution from the air to the sea. Therefore, ports and regions have already stated they will not allow the discharge of wash water from scrubbers.

This table summarises the positions taken by ports that have or will prohibit the use of scrubbers, or have placed conditions on their use.
