Our Story
The reliability of systems used in industrial facilities and ships is the cornerstone of long-term investments. However, today, poor material selection, habit-based decisions, and non-systematic approaches significantly undermine that reliability.
This leads not only to more frequent equipment failures, but also to:
-
Increased workload for maintenance teams,
-
Decreased operational efficiency,
-
Waste of energy and resources,
-
And greater environmental impact.
On the other hand, simply choosing the right product is no longer enough.
Constantly evolving and tightening regulations are pushing both industrial plants and vessels to adopt more environmentally friendly, efficient, and traceable systems. This transformation requires not only the right equipment, but also expertise and strategic guidance.
From day one, we have built our company on this need:
-
Combining global know-how with local experience,
-
Aiming to deliver the right solutions at the right cost,
-
And going beyond the conventional supplier-customer relationship to build true solution partnerships.
We exist to support facilities, fleets, technical teams and OEMs on their journey toward greater reliability and sustainability — not just as a vendor, but as a committed and knowledgeable partner.
We share the same motivation with everyone who wants to make the right choices today, for a better tomorrow.
Our Approach
Our Method
In critical applications, we offer problem-specific solutions, not off-the-shelf products that fit all.
Our Goal
Our goal is to transfer global know-how to the local market in order to improve the reliability and availability of facilities and vessels, to support maintenance and technical teams in OEMs, shipyards, fleets, industrial plants for more reliable and sustainable systems by guiding them through the transition to green economy and green shipping.
Our Values
We believe in science and technology, not habits.
We recommend the most technically accurate solution, taking into account the economic conditions.
We always tell the truth to our customers and stakeholders. We believe in the importance of long-term relationships.

Message from Our Founder
Whether it is a ship or an industrial facility, maintenance teams make great efforts to keep systems and equipment ready at all times. Another issue that challenges maintenance teams is budgets. For maintenance teams who are responsible for keeping equipment reliability at maximum levels while staying within budget, maintenance of industrial facilities and ships, availability and working with all systems at the performance they are designed for requires intensive knowledge and experience. SEM Industrial was founded by mechanical engineer Onur Özgen to provide services in the field of critical sealing, bearing and fluid control in ships and industrial facilities.
Our founder, who worked as a second engineer and chief engineer on various ships and as a design and field engineer in shipyards between 2004-2017, worked in product management at Borusan Cat between 2017-2019 and as Business Development Manager at James Walker Turkey between 2019-2023. He decided to establish a company in order to transfer his experience in the sealing field, especially at James Walker, to more engineers.
