Alternative Chocking Methods for Marine Engines

Metallic chocks require time and manpower for machining the foundation surfaces and engine seating, while epoxy resin chocks do not.
Resin chocks are made by mixing liquid resin with a hardener to create a chemical reaction that transforms it into a solid form.
Dams are placed between the bedplate and double bottom to contain the epoxy liquid, and closed cell foam is used to seal the dams.
Epoxy resin chocks provide a greater support surface for the engine or bedplate, and offer natural protection against engine and hull vibration.
Epoxy resin chocks should not be used in environments with temperatures above 80°C or ambient temperatures above 60°C.
The torque or tension required to tighten hold-down bolts for epoxy resin chocks is only a fraction of that required for metallic chocks.
Self-leveling chocks are height adjustable and re-usable, with a self-leveling top surface that accommodates angular differences between the bedplate and ship structure.
Height adjustment for self-leveling chocks is achieved by turning the upper ring, and they can be adjusted during the life cycle of the machinery.
Spring engine mounts are used in instances of high vibration or when the engine must be isolated from the ship's structure.
Spring engine mounts consist of upper and lower plates separated by one or more springs, with the lower plate bolted to the ship's structure and the upper plate bolted to a supporting frame.
Alignment of the generator and engine for spring engine mounts is done on the frame using other chocking methods.
Spring engine mounts are common in ship service diesel installations or diesel electric propulsion systems, especially in icebreakers.
