Eco-Friendly Marine Cleaning Solutions for Dry Bulk Carriers

Cleaning cargo holds on dry bulk carriers is a demanding and exacting task. Additionally, it needs to adhere to MARPOL Convention regulations and strict controls aimed at preventing and minimising pollution from ships. Compliance is a must.
We understand the challenge. The need to balance critical areas: the protection of your cargo, the shielding of your ship, and preservation of the marine environment.
The RBM team took up the challenge and developed cost-effective, tested & proven, environmentally friendly marine cleaning solutions that address all of these concerns. Here’s a quick summary.
Marine Cleaning Solutions
RBM HoldBlock®
RBM HoldBlock® is your go-to solution for dealing with caustic or greasy cargos. Sulphur, salt and fertiliser cargos are capable of causing extreme structural damage over time. Use our marine barrier to help mitigate this type of damage. It’s been proven to be more effective than lime wash by an independent laboratory–see images here. “The field results showed that HoldBlock gave very good protection against corrosion over the 42 day duration of the test.”- Independent Sulphur Research Company
RBM HoldBlock® also helps to resist staining from coal and other dirty cargos like green delayed petcoke. Its user-friendly application and easy removal with RBM HoldWash-HD® makes it the best choice for quick work on tight schedules. This is an environmentally friendly solution.
RBM HoldWash-HD®
RBM HoldWash-HD®is a versatile, heavy duty, all-purpose cleaner that easily breaks down hydrocarbons and removes RBM HoldBlock®. It’s the strongest, environmentally friendly cleaning solution on the market with the ability to penetrate more deeply and work longer. Crews ideally use it at full-strength for coal, or diluted to suit a wide range of cleaning applications. See our HoldWash photo gallery here.
RBM BilgeCoat
Acidic water is caused by sulphur reacting with water. It’s a real problem for dry bulk carrier bilges and bilge lines. We designed an alkaline solution called BilgeCoat, to neutralise acidic water. It has the added benefit of being safer and easier to use than caustic soda flakes. It’s also environmentally friendly and complies with MARPOL regulations.
Eco-Friendly marine cleaning solutions are a must-have for your dry bulk carriers and these RBM products are the perfect choice. As well as being safe for the environment, they are non-toxic to people and can be safely used in occupied or covered areas.
