Clamps need regular checkup, especially those on the ship. The recommended interval is at least 1-2 times per quarter, to make sure that the clamps are still in good condition. Follow the guideline below:
Take a look at every clamp. Make sure there is no rust, looseness, or defect.
Use a flashlight and mirror to check the clamps that are not normally visible, for example, those at the aft end of shaft gland, or washdown/live well hoses.
Sanitation hose clamps are more prone to corrosion due to substances that go through the hoses. Therefore, it is as important to take a closer look in this area (including head and holding tank treatments), as leakage may result in unwelcome odour, or even worse, hygiene issues.
Make sure that bilge pump hoses are firmly clamped to the pump. Looseness may cause excess battery usage of the pump, and also ineffective suction of water from the bilge.
Another area that needs extra attention is bilge blower hoses, especially those on inboard-powered ships with gasoline engines. A detached hose is not only useless, but also increases the risk of explosion.
2 hose clamps are required for the joints in exhaust systems where a flexible hose is connected to a stationary part, for example a muffler.
Apart from clamps, make sure the hoses are in good condition. Hoses that are too-tightly clamped may be cut into, leading to higher chance of leakage.
Also use a screwdriver or nut driver to check the screw of the clamp. In case of looseness, consider replacing the clamp.
