MATERIAL BENEFITS
The benefits of using composites for superyacht refits are numerous. Mark Branagh, Managing Director of BM Composites shares his company’s visions and objectives
T
here are many design companies and refit yards around Europe who have embraced the advanced use of composites and with that been able to expand their refit capabilities. However, some are still resisting the change that will inevitably happen. Mark believes that using composite materials is the way forward for so many reasons.
Let’s consider just some of the positives • No limitations on shape - a designer can have a free hand without physical material limitations.
• Weight saving equals reduced fuel consumption
• Stability and class compliancy - some additions at height can only be achieved using lightweight composites
• Zero corrosion - and repaint cycle
lower maintenance
• Components completed and painted off site then glued and / or fastened in place giving minimal disruption on board the vessel, increasing overall productivity during a refit. Often allowing fitting to be completed in a matter of hours rather than days or even weeks
• Areas of the boat can be 3d scanned to 0.2mm accuracy, and parts can be built, painted and ready to fit prior to the boat even entering a yard
• No need for yard space as parts can be built off site and transported to the refit yard
• The latest materials and resin systems have made huge advances in recent times to comply with current and future fire regulations
• No hot works on the boat reduces overall costs and minimises disruption to other areas of the vessel, namely interior and systems.
Compared to the negatives There really is only one…
..that is the raw material and basic construction cost is marginally higher, but it really is a false economy in most cases when considering the cost and results of the finished product delivered to the owner.
For example, the construction tolerances are far more refined when building with composites due to the way we process most parts or structures, this is particularly evident when trying to match other areas of the vessel with complex shapes and curves thus greatly reducing the finishing costs.
Consider the maintenance costs of a modern composite structure against the same in steel or aluminium. The protection and aesthetics of any superyacht is always high on the list of priorities so when you look at the overall spend including the corrosion
treatment and associated logistics in performing
those maintenance tasks,
the return on investment in building with composites comes a lot quickler than people think. Then, when you start to consider the long-term savings over a 5 year period for example, there really is no comparison.
From a design perspective, using laser scanning technology, naval architects can now create a perfect virtual 3d image of the boat. This enables accuracy and versatility during the entire process from the initial design stages through to CNC production of moulds and parts. This whole package of design allows you to create photo like images that show the concept accurately to the client before construction begins. When you have this level of clarity it also lends itself to more structured pricing and the elimination of extra costs at the end of a project.
BM Composites have been at the forefront of the promotion of composites within the superyacht industry for 13 years. But it’s not just refits that they specialise in. The components of a large motor yacht can be evaluated, identified and built separately off site. With their dedication to R&D and their strong connections to Gurit, the world’s leading composite engineering and materials provider, BMC are pushing the boundaries of what can be achieved by looking at what can be done rather than what generally is or has been done in the past.
