In 2025, SEIKOH officially announced its new corporate mission and values, reinforcing its professional position as a technical partner of the globally renowned marine engine brand YANMAR, while demonstrating its long-standing dedication to service quality, technological advancement, and customer trust.

SEIKOH has long been rooted in the marine engine and generator business, offering a comprehensive range of services including after-sales repair, maintenance consulting, and technical training. This update of our core values is an active response to the rapid evolution of industrial technologies and the continuous upgrades of maritime safety standards.

Four Core Values That Build Long-Term Trust



 1. Self-care Begins
Safety and discipline form the first line of defense in all SEIKOH services.

When dealing with marine engines, heavy machinery, and other high-pressure, high-temperature equipment, every step on-site carries potential risks. SEIKOH believes that true professionalism begins not with skills but with the cultivation of safety awareness. That’s why every member of our team—from front-line technicians to back-office support—strictly adheres to standardized safety operation procedures to ensure focus and responsiveness in any situation.

Self-care is not about avoiding risks, but about establishing a disciplined culture capable of managing risks over the long term. Only when every technician can return home safely can we continue to shoulder the responsibility of safeguarding each voyage.

2. Accuracy Counts
Repair is not a temporary fix—it’s the foundation of long-term trust.

When equipment malfunctions, a quick part replacement or minor adjustment may only address surface-level symptoms. SEIKOH emphasizes uncovering “the problem behind the problem.” Through systematic diagnostics, failure history analysis, and cross-referencing multi-source data, we identify the root cause to prevent recurrence.

Our technicians are not only well-versed in mechanical structures but are also equipped with logical reasoning and diagnostic skills. They can detect hidden, potential risks from seemingly trivial on-site clues.

3. Forever Learning
Learning is more than training—it is the core of our company culture.

In the face of continuous global advancements in maritime technologies—from electronic control engines and remote monitoring systems to hybrid power and sustainable fuel technologies—maintenance is no longer merely mechanical. SEIKOH treats the ability to learn as equally important as technical expertise.

We invest heavily in internal training systems, including factory-certified programs, international experience exchanges, and hands-on failure case workshops. Every technician is encouraged to actively track new knowledge, report on-site observations, and engage in peer knowledge-sharing, allowing the entire team to support one another's growth.

Only through continuous learning can we quickly understand the logic behind new equipment, propose customized repair solutions, and earn our customers’ trust to place their vessels in our care.

4. Expertise Speaks
Trust is built through professionalism and integrity visible in every detail.

We understand that customers cannot directly assess the health of an engine—they must rely on the information, analysis, and recommendations we provide. That’s why SEIKOH is committed to delivering all service records and reports based on facts and governed by transparency.

Whether it’s routine maintenance or a complex overhaul, we offer full inspection records, failure analysis reports, and repair suggestions. We clearly communicate timelines and costs before any work begins, avoiding hidden charges. This structured, traceable professional process is how we practice integrity. Expertise is not a slogan—it’s a result that stands up to scrutiny.

SEIKOH is not only the exclusive agent of YANMAR in Taiwan but also a trusted brand across marine, energy, and engineering sectors. From marine and land-based generators to urban electromechanical systems, we offer around-the-clock repair support and integrate consulting and training services to help clients establish stable and predictable operational mechanisms.

This update to our mission and values is more than a redefinition of corporate culture—it represents SEIKOH’s long-term commitment to technical excellence and industry trust. Moving forward, SEIKOH will continue to speak the language of technology and uphold the standard of integrity, standing alongside every voyager.
