About SeaMar

Maritime Experience. Family Values.

More than two decades of maritime experience, shaped by people who take ownership and care about doing things right.

Our story

Growing through experience

Since 2000, SeaMar has grown from a family-owned business into an experienced maritime service partner supporting clients around the world. What started with a strong foundation in ship management and agency services, gradually expanded into shipping and ultimately safety services.

As relationships with our clients grew, so did the scope of our involvement. Over the years, we brought together a wider range of expertise, services and capabilities to support our clients at every stage of an operation.

Today, that combination allows us to contribute in ways that go beyond the original request.

Who we are today

Driven by dedication

Years of experience have shaped the way we work, but it is the commitment of our team that makes the difference. Our people genuinely care about what they do. Together, we look beyond the immediate request, see what is needed and take action where we can make a difference.

Whether supporting a client, crew or colleague, the goal is always the same: to keep things moving in the right direction. We feel responsible for every detail and are proud of the role we play in making every operation a success. This way of working has been part of SeaMar from the very beginning. We have built it on collaboration, trust and a shared ambition to deliver the highest standards of quality.
