Seven truths about independently sourced spare parts and service
an article written by EMISA
1
The term “OEM” is up for debate
What “original equipment manufacturer” or “OEM” means is debatable. Some people consider the engine makers to be the OEMs, while others define it as the manufacturers producing the parts that engine makers assemble into the complete engine. Engine makers claim they are the OEMs, being recognized by manufacturers and classification societies in the industry. In reality, an official definition of OEM in the marine industry (e.g., from legal texts or other official documents) still does not exist.
The same lack of clarity exists worldwide – OEM can be defined differently depending on the industry and even the region of the world. In the electronics industry, for example, OEMs are the parts manufacturers that supply the companies that assemble and sell the finished product. While clarifying where the parts come from without confusing the customers is important, OEM can be used vaguely. So, not all manufacturers are OEMs, according to some, but they might be OEMs, according to others.

Many independent suppliers make the origin of the parts clear
The origin of the parts is crucial for the customer. As a supplier, one must always make it clear where the parts come from. If they come from the engine manufacturer and bear their brand, they are genuine. If not, then they are non-genuine, otherwise called alternative spare parts.
At the same time, it’s important to remember that labels such as “OEM” and “genuine” also serve a marketing purpose. On one hand, they can be used in false and misleading advertising by certain companies. However, many independent companies are honest about the parts’ origin, ensuring customers get what they pay for. On the other hand, even if a part does not have the label of “OEM” or “genuine,” it does not necessarily mean that it will perform worse than the parts that do.
Customers can find non-OEM and non-genuine parts that offer the same quality, often at a lower price. It all comes down to proper research and knowing the suppliers.

Good quality is not exclusive to OEM and genuine parts
While there is no guarantee for the quality of non-OEM parts from the OEM, this does not necessarily mean that the quality will be inferior. After all, plenty of independent companies supply non-OEM parts that satisfy their customers’ needs in terms of quality and reliability.
When it comes to reverse-engineered parts, independent manufacturers often take great care to produce a part that matches the original parts in terms of quality of materials, performance, and tolerances by sampling the genuine part.
4
Parts made by the same component manufacturer are often a great option
Many manufacturers supply spare parts to the aftermarket, which are made to serve the same purpose as the parts they manufacture for a certain brand. These parts are often more cost-effective while they offer the same or similar performance, which is why many customers choose them.
While they might not be the same parts, manufacturers such as these usually have plenty of knowledge and experience, allowing them to design and manufacture parts that are up to par with genuine components in terms of performance and durability.
5
Vessel compliance does not always depend on OEM parts
In our experience, this depends on the surveyor, and even the same classification society might have a slightly different view on this, depending on their regional office.
Regarding the NOx parameter method and the NOx-affecting components, if a parts manufacturer can prove that their parts correspond to the parts installed in the parent engine test, then compliance is generally not an issue. Manufacturers and suppliers can often offer documentation, certifying the correspondence of the parts as tested, meaning that the performance of the parts is within the allowed tolerances and quality standards. Compliance with the warranty can depend on the engine maker’s and the customer’s agreement. Certainly, during the engine’s warranty period (usually around five years), installing non-genuine parts could sometimes void the warranty. However, many independent suppliers offer warranties for parts that are the same or similar to those offered by engine makers/OEMs. In some cases, independent companies even offer additional liability insurance, which can even exceed what engine makers/OEMs offer.
6
Non-OEM parts are usually more cost-effective
Spare parts prices can vary between suppliers; however, generally, non-OEM parts can be more cost-effective to buy. This is due to the lack of branding, lower reverse engineering costs compared to designing and testing a new component, and the availability of different options for aftermarket parts.
Even if the parts themselves are not more cost-effective, independent companies can often deliver them quickly to any point in the world, also providing skilled technicians to install or repair the parts.
7
Non-authorised resellers can benefit customers
Independent companies, as opposed to authorized resellers, are not affiliated with the engine manufacturers. That means that internal rules and policies may not limit them, and they can be more flexible and attentive to their customers, finding innovative solutions on a case-by-case basis.
Independent companies can offer:
- good quality
- expertise, often focusing on a specific type of parts or engine brand or model
- lower prices
- flexibility
- faster delivery times
- sustainable solutions – reconditioning and remanufacturing components to extend their life
- more attentive customer service due to their smaller size.
Conclusion
The aftermarket offers a wide variety of spares, genuine or not. Shipowners can research their suppliers, learn more about the origin of the parts, and make a decision that is in their best interest regarding cost, reliability, and quality.
After all, plenty of successful independent companies offer good-quality non-OEM parts and services to their customers. Sometimes, OEMs and engine makers even hire independent companies as subcontractors for installation and repair. That is a testament to the fact that non-OEM parts and services can be a great option.
Finally, an aftermarket with only OEM parts could ultimately lead to monopolization, often with less choice, higher prices, a lack of incentive to innovate, a drop in quality, and a strained supply chain. Independent companies allow the market to foster innovation and challenge all market players to continue developing their services. That is why we continue to raise awareness and promote the independent aftermarket.
