To provide a clamping force through friction between bedplate, chock and the ship’s structure in order to resist the propeller thrust. In new vessels, the bolts should be checked within one month of. Also, check for shearing and fretting on the holding down bolts. When the chocks and their mating surfaces on the bed plate and tank top have fretted, the chocks cannot properly support the engine. Holding down bolts for modern main propulsion slow speed engines are of the ‘long sleeve’ type, and are hydraulically tensioned. Purpose of holding down bolts: Tried to include the preparations. The floor where main engine is situated is strengthened by additional bars and griders. Support weight of the engine. Secure engine rigidly in all sea conditions. Check for loose holding down bolts and tighten as per the manual if found loose. Marine engine is a massive structure so its very important to securely fix the engine into the ship hull.
