Cargo residues are usually found concealed in the bilges, recesses below manhole covers, upper sections of the ship's frames, and bulkhead corrugations during hold cleaning on a general cargo vessel.
To find the answer to your question, you can refer to industry guidelines and best practices for hold cleaning on general cargo vessels. One such resource is the International Maritime Organization (IMO) Code for the Safe Carriage of Grain in Bulk, also known as the IMSBC Code.
According to the IMSBC Code, cargo residues on general cargo vessels are commonly found concealed in several areas. These areas include bilges, recesses below manhole covers, upper sections of the ship's frames, and bulkhead corrugations.
It is important for crew members and cleaning personnel to thoroughly inspect these areas during hold cleaning to ensure that all cargo residues are removed. This helps maintain a clean and safe environment for the vessel's cargo operations.
If you are directly involved in hold cleaning on a general cargo vessel, it is recommended to follow the guidance provided by the ship's operator, the vessel's specific procedures, and any applicable regulations and guidelines such as the IMSBC Code.
During hold cleaning on a general cargo vessel, cargo residues are usually found concealed in the following areas:
1. Bilges: Cargo residues can accumulate in the bilges, which are the lowest parts of the ship's compartments where water and other liquids may collect. These residues can settle in the bilge water and may need to be pumped out or cleaned.
2. Recesses below manhole covers: Cargo residues can also be found in recesses or small spaces below the manhole covers, where they can accumulate and be difficult to reach and clean.
3. Upper sections of the ship's frames: Cargo residues can sometimes get trapped in the upper sections of the ship's frames, which are the structural members that provide support and rigidity to the ship's hull. These areas may require extra attention during cleaning to ensure all residues are removed.
4. Bulkhead corrugations: Cargo residues can hide in the corrugated sections of the ship's bulkheads, which are the vertical partitions that separate the different compartments or holds. These corrugations can provide crevices where residues can accumulate and be hard to remove.
Please note that cargo residues can also be found in other areas depending on the specific cargo being transported and the configuration of the ship's holds. It is important to thoroughly inspect and clean all areas to ensure proper cleaning and maintenance of the vessel.
