Engine Mountings - Main Engine and Propulsion

Marine engine mountings are resilient rubber-metal or elastomeric supports fitted between propulsion engines and vessel foundations. They carry static and dynamic loads while reducing structure-borne vibration, shock and noise transmitted into the hull.

ProShipWorks provides end-to-end support to source and supply Engine Mountings for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval

Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.

Applicable Standards & Certification	Selection and vibration assessment may reference ISO 20283 series for ship vibration and ISO 20816 series for machinery vibration. Material, fire-performance and installation requirements depend on vessel rules, engine maker instructions and the approved propulsion arrangement.
Class Approval	Approval is normally product-, vessel- and installation-specific. Mountings and foundation calculations may require review by DNV, ABS, Lloyd's Register, Bureau Veritas, ClassNK or another vessel classification society.

Installation, Maintenance & Safety Information

Installation Notes	Select mounts from verified engine mass, center of gravity, torque, thrust arrangement, excitation frequencies and foundation stiffness. Install on flat reinforced seating, distribute load evenly, maintain specified alignment and height, and follow engine, gearbox, coupling and mounting-maker instructions.
Maintenance Tips	Inspect periodically for rubber cracking, hardening, swelling, corrosion, loose fasteners, abnormal settlement and oil or fuel contamination. Check engine alignment and mount deflection after commissioning, grounding, heavy shock, overhaul or mount replacement.
Safety Notes	Support and secure the engine before loosening or replacing mountings. Do not exceed rated load or adjustment limits. Use compatible mounts as a complete engineered system, maintain required shaft alignment, and prevent prolonged contact with fluids that attack the elastomer.
