We go a few steps further, thanks to years of experience and a practical eye, know how to solve problems before they arise. In this way ideas and dreams now become reality. We list a description of separate services we offer that relate to all marine engineering jobs.

No plan overboard

Everyone works in their own way and construction projects also involve a lot of logistical flows. From many years of experience and dedication we have developed methods that lead to profit for both customer and producer. From a smoother construction time to cost savings. Consultancy by tackling obstacles early and coordinating all parties. Because of this, no plan goes overboard with us.

Who doesn’t want to hear …

We’re listening. Our theoretical and practical experience at shipbuilding architects and shipyards has revealed that there is no such thing as “knowing it better”. The difference lies in listening, to wishes and requirements, but also to the input of each party. This way we add exactly what is needed and projects are completed faster and better.
Do you want to discover how your next project can be even better, or how we can help you save hours guaranteed? Let us help you.

Dear visitor,

After years of close collaboration between Rottiné Marine Engineering (formerly Waterline-Design) and Stalker Marine, we have decided to join forces. During this period we have experienced growth, not only in the number of assignments, but also in focus. It was time for a new step in our collaboration. In recent months, we have worked hard to prepare and shape our new company. This website is updated in which our expertise and working methods will come to the surface better. This renewal can also be found in the company name. From now on the names Rottiné Marine Engineering and Stalker Marine will sink to the bottom and make way for:

Reav & rottiné

With this change we will be able to serve you even better. Of course, nothing changes in our method!

After the website has been adjusted, we will regularly share our knowledge and vision in the field of Engineering, LEAN Shipbuilding and Consultancy in a blog and via the renewed channels on Facebook and LinkedIn.
