SCU

Sludge Collecting Unit

ShipCore’s Sludge Collecting Unit (SCU) streamlines sludge handling, reduces manual cleaning, enhances crew safety, and enables reuse of valuable "total loss" marine lube-oil.

Automated sludge separation for cleaner operations

Scavenge air drain tanks are often inaccessible and difficult to clean, hidden away beneath floor plating in the engine room. This makes maintenance time-consuming and hazardous for crew members, exposing them to toxic substances and difficult working positions.

The Sludge Collecting Unit, SCU, solves this problem completely. With its simple and robust design, it removes the need for manual cleaning while ensuring efficient separation of solids and liquids – all without any moving parts for maximum reliability.

Why choose SCU?

Lower costs: Minimize cylinder oil consumption
Lower sludge disposal costs
Effortless solid waste handling
Minimal maintenance
Improved crew safety
Enables oil reuse

How the SCU works

The SCU collects sludge from scavenge spaces and separates solids from liquids using gravity – ensuring a fully passive, maintenance-free operation.

Sludge Collection
Excessive oil and sludge from the scavenge air drains flows directly into the SCU for separation, without the need for any manual interaction.
Gravity-Based Separation and Collection
Inside the SCU, gravity separates liquids from solids. Clean oil flows freely, while solids remain trapped in the oil barrel for easy replacement when full. With no moving parts and no power required, the system is fully passive and highly reliable.
Clean Oil Flow & Reuse
The separated oil, free of solids, flows downstream into the scavenge air drain tank. From there, it can be drained into the vessel’s existing sludge system or reused via ShipCore’s Lube Oil Reuse System (LRS) for improved efficiency and sustainability. Click here to read more about ShipCore LRS.

With no moving parts, the SCU provides a reliable and cost-effective sludge management solution that seamlessly integrates into existing systems.

Lube Oil Reuse System (LRS)

ShipCore’s Lube Oil Reuse System (LRS) revolutionizes the handling and lifetime of lubrication oil for maritime 2-stroke engines.

Working together with the ADCS and SCU, the LRS reuses lubrication oil to be reintroduced into the engine. This drastically lowers the total cost of lubrication oil used to operate the engine and lowers emissions from fossil fuels by reusing rather than paying to dispose of excess oil.

With ShipCore’s LRS, improved sustainability also means an improved ship economy.

Sludge Collecting Unit (SCU)

ShipCore’s Sludge Collecting Unit (SCU) removes the need for manual cleaning of scavenge air drain tanks and is central to facilitating the repurpose of oil drained from the engine to be reintroduced as reuse cylinder lubrication oil in our Lube Oil Reuse System (LRS).

With the SCU, engine crews save a significant amount of man hours on cleaning duties, improving working conditions by reducing the exposure to hazardous substances.

Hapag-Lloyd

Testing our Automatic Drain Cleaning System (ADCS) for the main engine (M/E) drain pipe system and scavenge space with Hapag-Lloyd.

Maintaining engine efficiency and reliability is crucial in ship operations. Hapag-Lloyd, with their many years of operation, know this as well as any company. We are very happy to have been able to draw on their experience and professionalism in testing our products.

After two years, our system is still in operation and has shown many impressive results on Hapag-Lloyd's ship, MV "Brussels Express".
