Ship owners and operators often prioritize purchasing critical engine components from OEMs, but even less critical parts, when sourced from non-OEM suppliers, can lead to significant issues.
Seals
Seals prevent water, dirt, and dust from entering the engine and stop fluids from leaking. Non-OEM seals, though seemingly similar, may be unevenly cut and made from inferior materials, leading to premature wear, leaks, and even engine fires. The costs of repairs and downtime far outweigh the savings from using cheaper seals.
O-rings
O-rings, essential for sealing, must be made to specific standards. Using non-OEM O-rings or the wrong type for the application can result in leaks, corrosion, and unplanned downtime. For example, using an O-ring intended for oil in a cooling water system can lead to water leaks and corrosion. Genuine O-rings, designed to OEM standards, ensure proper performance and long-term cost savings, as they are manufactured with the right materials and tolerances for their specific applications.
Bolts and Nuts
Fasteners like bolts and nuts hold ship components together and must endure harsh marine conditions. Non-OEM fasteners might not meet the necessary standards, leading to potential breaks, leaks, or engine damage. For example, using the wrong fastener can damage rods connecting engine pistons to the crankshaft or cause valves to fall into the engine cylinder, leading to turbocharger damage or complete engine failure. OEM fasteners ensure durability and proper performance, preventing expensive repairs and downtime.
