HATCH COVER REPAIR IN VIET NAM

HATCH COVER REPAIR

Leaking hatch covers are a common cause of cargo wetting, and this can lead to more serious consequences than just wet cargo. Flooding, accelerated corrosion, and even loss of the ship can occur if hatch covers are not maintained properly or closed correctly. It is therefore essential to have weathertight hatch covers that can prevent the passage of water into the ship, even in adverse sea conditions.

Hatch covers are designed to be weathertight, which means that water should not penetrate the ship through the covers or the double drainage system. However, minor leakage during a hatch cover test is often erroneously considered to be within a weathertight standard. The purpose of a hatch cover is to prevent water from entering the cargo hold after a large opening has been cut in the deck for cargo access. These moveable structures are constructed to be lightweight and weathertight.

Modern design methods, using finite element technology, enable more efficient material distribution, resulting in lighter and thinner hatch cover structures. Construction from high tensile steel also allows for even thinner plate usage. To prevent corrosion, regular examination of hatch covers, hatch beams, and coamings is necessary to identify general levels of corrosion, localized corrosion at welded connections, cracks in joints and weld metal, permanent distortion of plating and stiffeners, indications of excessive corrosion, cracks in main structural joints, and missing or damaged hatch gaskets.

It is also important to keep hatch coaming tops clean and double drainage channels free of obstructions, replace missing or damaged hatch gaskets immediately, keep cleats and wedges in serviceable condition and correctly adjusted, test hydraulic oil regularly for contamination and deterioration, keep hydraulic systems oil-tight, and clean up oil spills. Regular maintenance of hatches is more effective and less expensive than sporadic inspection and major repair. With these measures in place, cargo wetting and other serious consequences can be prevented

When it comes to hatch covers, maintenance is key to prevent leakage and ensure weathertightness. Regular examination of the hatch covers, hatch beams, and coamings is essential to identify potential issues such as corrosion, cracks, and distortion. It’s important to replace missing or damaged hatch gaskets immediately and keep hatch coaming tops clean and double drainage channels free of obstructions.

Hatch covers are typically lightweight steel grillages, and modern design methods enable more efficient material distribution resulting in lighter structures. However, prevention of corrosion is still essential, as safety margins are finite. The use of high tensile steel enables even thinner plates to be used, but this also means that these structures must be handled with care.

In addition to regular examination and maintenance, hydraulic systems must be kept oil-tight, and hydraulic oil should be tested regularly for contamination and deterioration. In the event of an oil spill, it’s important to construct a save-all to contain the oil and empty it regularly.

Overall, continuing and regular maintenance of hatches is more effective and less expensive than sporadic inspection and major repairs. By taking a proactive approach to hatch cover maintenance, shipping companies can avoid the serious consequences of leaking hatches, such as cargo wetting, flooding, accelerated corrosion, or even loss of the ship.
