How our journey began

While working for a shipyard in Finland in 1987, Merima co-founder Mauri Mäkiranta wanted to give something more to Finland’s shipbuilding industry. After completing his first cruise ship, he began to explore entrepreneurship and partnered up with Timo Nisonen to launch Merima.

For Mauri and Timo, shipbuilding is a passion – a calling. So much so that they risked everything and put up their houses as security to build the capital necessary to launch the company.

In the beginning, nothing seemed to go as planned. They needed to work hard to persist and continuously learn to overcome difficult challenges – values that have become ingrained in our everyday culture and way of working. Understanding the customer’s business and reacting agilely to changing needs has always been the key to our success.

But then Merima started to grow rapidly, with the company launching its production facility in 1988, smashing its growth target in just three years. By 1993, the company needed bigger facilities, so it moved to Helsinki, which has remained its headquarters ever since.

By the late 90s, Merima was a leader in the industry, successfully working on the new construction of some of the world’s most iconic cruises and luxury passenger ships.

During the 2010s, Mauri Mäkiranta´s children Mikko Mäkiranta and Minna Mäkiranta-Blyth became shareholders of the company, making Merima Oy a 100% owned family company. With Mauri later retiring in 2020, he handed the position of CEO over to his son, Mikko.

Dynamic pioneers in shipbuilding

Today, Merima’s team continues Mauri and Timo’s heritage of continuous development, employee well-being, and ensuring customer satisfaction. At Merima, our values drive everything we do, and we take great pride in our ability to work agilely and dynamically.

As an international company that has worked with the world’s most iconic vessels, our expert team knows how to take a ship to the next level. We also work hard to maintain and deepen the relationships with our collaboration partners and network so that we can produce solutions that create the “wow-effect.”

In the Merima extended family, shipbuilding isn’t just our passion – it’s personal.

“A key driver of our business has been continuous development – it’s strongly ingrained in our company culture and it’s a big reason why we are here now. It’s also what will take us to the next level. We are extremely ambitious and we always offer the best quality and flexibility for our clients.” ”
