Hold-Protection-Sheet System
We provide this system that makes it easy to clean a hold after unloading, and significantly reduces cleaning time and cost. This system is installed in holds before loading and reduces contamination after the unloading of bulk cement. This large-scale system, which covers the entire hold wall, is characterized by easy installation and removal.
Since the news release of January 2006, we have been steadily receiving inquiries about the sheet system from the cement market and other bulk markets where the sheet system is highly regarded. Patent received November 2009
Summary
The sheet will be used in the holds of Handysize bulkers (bulk carriers of about 23,000 to 58,000 deadweight tons), which are mainly used for bulk-cement transportation. When bulk cement is loaded into a hold, the cement absorbs moisture from the air and sticks to the hold wall. After unloading, cleaning such a hold takes three to five times longer and costs considerably more than cleaning a hold after the transport of other cargo. This extended cleaning interval lengthens the time between unloading the bulk cement and loading the next material for transportation.
The newly developed protective sheet reduces contamination and makes cleaning of the hold much easier. Moreover, the sheet can reduce dust levels, thus improving the working environment.
The NYK Group will further modify and improve this sheet for use with other bulk products.
Features
Making it easier to clean holds after unloading bulk cement
- Covering the hold wall with the sheet prevents cement adherence to the walls and so significantly reduces cleaning time and cost after unloading.
Reduction of dust during loading and unloading
- Bits of hardened cement easily slide down the sheet, which slipperiness prevents chunks of cement from forming on the walls and later falling. This phenomenon greatly reduces the dust from falling cement and improves the work environment in the hold.
Examples
- NYK Global Bulk Corporation, the co-developer, is now conducting on-site verification and making further improvements.

Specification
- The sheet is made from an original polyethylene fabric with a polyethylene coating and is sewn together with a special method to resist pressure from the cargo.
Notice
- Basically, the sheet cannot be reused.
- The sheet, which is made of polyethylene, can be incinerated.
- The sheet cannot be used with combustible cargoes.
FAQ
- Q: Are any specific techniques required to install the sheet?
- A: Nothing special. Just three crewmembers are needed to install the sheet. A supervisor will be dispatched for the first installment.
