What is Green Delayed Petcoke? Is it hard on ships’ holds?

Green Delayed Petcoke is hard on ships’ holds, requiring careful cleaning and good bulk carrier hold protection. Let’s look at the reasons why, and what you can do to protect your ships’ holds.

Petroleum coke, shortened to petcoke, is produced when crude oil is processed into fuels like gasoline. This refining byproduct has a high fixed carbon content made up of hydrocarbons and low levels of inorganic compounds. It comes in various forms, including powdered, granular, needle-like, calcineable, and green. 

Green petcoke, also known as raw or delayed petcoke, is unprocessed coke fresh out of the coker.  Canada produces its supply from the oil sands in Alberta. From there it makes its way to Vancouver ports for shipping worldwide.

Some types of petcoke, like the calcined variety, are fairly dry and easily cleaned from a ship’s cargo hold. Green delayed petcoke, however, is high in oil content. The stubborn stains it leaves behind are challenging to clean. The longer it’s left, the more difficult it becomes. As soon as possible, thoroughly remove all of the residue with a high-pressure sprayer. Afterwards, a cargo hold barrier should be sprayed in place to protect the steel.
