Superstructures for yachts_

Weight problems in yacht building often occur near the end of the structural construction phase. The increased weight combined with stability requirements demands lightweight superstructures. Multiple superstructures have to date been designed by Solico.

Waterbus composite ferry_

Solico engineered the complete structure of the Damen Waterbus composite ferry, consisting of hulls, deck and superstructure. The waterbus concept is built around flexibility in configurations which can be changed even when production has already started. To date, this one of these ferries can be seen cruising the waters of Antwerp. 

Maeslant storm surge barrier_

The Maeslant barrier has been fitted with new bearings, using composite materials, which have been developed by Rijkswaterstaat and Solico. These bearings combine a low friction coefficient with a very high load capacity. For this purpose, steel bearings are not strong enough. The use of composite bearings has proven to be highly efficient as this has led to time and cost savings in the maintenance activities.

Chemical/corrosion resistance

Composite materials are resistant to a lot of chemical products such as acids, hydroxides, crude oil, etc. Corrosion resistance against salt and seawater is excellent.

High stiffness to weight ratio

The stiffness to weight ratio of a high modulus carbon fiber construction is typically 5 times higher than steel or aluminium.

Sonar/Radar Transparency

Composites are very well known for their transparency to radar and low damping properties.

Freedom of geometry

Double curved shapes are easily produced in composite materials at almost no extra cost. For production of limited series the relatively low moulding costs are an additional benefit.

Limited thermal expansion

Thermal expansion of composite materials can be tuned. Depending on the fiber used it can vary between 0 and 30 where steel has an alpha of 12.


The non-magnetic properties of glassfiber reinforced composites are a major advantage especially in sonar and radar applications.

Low maintenance

Steel structures typically require periodic maintenance such as conservation and paint systems to prevent corrosion. Composites are not susceptible to corrosion resulting in lower Life-cycle costs.

Cost effectiveness

Though composite materials themselves are slightly more expensive than metals, combining properties such as insulation and weight savings often results in a cost effective product.


The fatigue resistance of composites is much better than that of metals. Of course fatigue failure also occurs in GRP and CFRP and has to be analysed in detail.


Typical GRP lambda values are 1, compared to 50 for steel and 237 for aluminium, which results in excellent insulation properties.

High strength

In general, fiber reinforced plastics outperform metals (e.g. steel and aluminium) in strength.


The specific weight of composites varies between 1.5 and 2.0 compared to 2.7 to 7.8 for aluminium and steel.


Slender constructions and seamless fa├žades are examples of aesthetics driven design. These type of structures are impossible to construct with traditional materials.

Integration of functions

By combining functions such as strength and insulation in one product, a composite solution is often more cost effective than the sum of traditional solutions.
