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.
