The Marimecs Group brings together several independent brands, one of which is Marimecs, serving shipyards, owners and suppliers.

Ship design and engineering

Marimecs combines 3D-design with traditional drafting skills to deliver advanced engineering packages to speed-up your building process.

Cost-efficient

Our projects cover commercial and new built yachts up to 140m. We continuously strive for cost-efficient and aesthetically pleasing results.

Future proof

Marimecs delivers solutions that suit your demands by developing sustainable and future proof vessels.

From the first line to interior arrangements

We take pleasure in developing creative one-off solutions for challenging technical demands of custom niche-vessels. Marimecs applies accompanying detail engineering for ship constructions and piping systems on board yachts and commercial vessels.

Concept design
One of the most interesting challenges is the development of a new vessel tailored to the requirements of the ship owner. The starting point is always the intended use of the vessel and the sailing area conditions. These are defined in a design brief and functional breakdown, developed in close cooperation with the ship owner. The concept design of commercial ships often calls for innovative and well-considered solutions.

Once the initial design concept has been established, the next step is a comprehensive set of hydrodynamic and structural analyses. These analyses are carried out using specialized software to assess resistance and seakeeping behaviour.

Upon request, Marimecs can assist in the selection of a suitable shipyard and major equipment, and provide supervision during the construction process, including commissioning. In addition to delivering complete new designs, Marimecs can also be part of the ship owner’s and builder’s design team.

Basic & detail engineering
Apart from design and naval architecture, Marimecs provides accompanying detail engineering for ship structures and piping systems on board yachts and commercial ships. The team develops creative one-off solutions to meet challenging technical requirements for custom and niche vessels in both sectors.
Conversions & modifications
With long-standing experience in both workboats and super yachts, one of Marimecs’ core activities is the conversion and modification of existing vessels. The team has extensive experience with complex conversions aimed at extending the useful life of vessels, adapting them to new operational requirements, or enabling alternative future use across both commercial and high-end yacht sectors.

Marimecs consistently strives for cost-efficient and aesthetically pleasing results. By combining expertise across multiple segments of the marine industry, practical and well-balanced solutions are developed that best suit the client’s demands and wishes for future use and long-term value.
