MV Marine defines a new way of conceiving the inflatable boat, with the Global Integrated Project (G.I.P.), an innovative solution that aims to reduce environmental impact, raise quality standards and contain production costs. This new approach is based on four fundamental concepts:
MV Marine's technical team consists of three 3D CAD/CAM design engineers, a technician specializing in the 5-axis CNC milling center, and a digital cutter technician.
3D CAD software makes it possible to model technical and stylistic solutions, looking for original and balanced combinations of shapes and colors. Thanks to this type of design, it is possible to optimize the water lines of the hulls and make an accurate assessment of hydrostatic and hydrodynamic parameters. Such software is also essential in verifying the ergonomics of every construction detail, optimizing spaces and interaction with human beings.
3D CAD design enables MV Marine's technical team to engineer production processes, a key aspect in selecting the most suitable materials and optimizing their use, allowing the assembly of the various elements to be simulated. Only through this careful study can the benefits of new construction techniques be achieved.
With the advanced use of CAM, we go from design to materialization using the milling center and digital cutter;
models are made with millimeter precision, reducing machining time and ensuring superior quality and finish.
After the careful initial phase of hydrostatic and fluid dynamic design and simulation of the hulls in a 3D CAD environment, the various solutions are tested using scale models in the tank at the hydrodynamic experiments laboratory of the Department of Naval Engineering at the Federico II University of Naples.
In this context, key parameters are measured, such as resistance to motion, longitudinal trim angle in stroke, vessel elevation in navigation, and wave behavior. The collected data are carefully compared with the design parameters and practical experiences of the shipyard, only the proven solutions move to the next stage: the realization of the real model.
With the collaboration of the CNR in Naples (National Research Council), the materials to be used in production are carefully tested in the laboratory, to assess their technical characteristics, before moving to the production stage.
By means of the numerical control center, both new models and all semi-finished products destined for production are made, and with the computerized digital cutter, fabrics for upholstery, EVA-TEAK panels, foam cores for infusion, neoprene fabric for tubulars and more are cut with millimeter precision.
MV marine with its resources gives customers the ability to customize their own boat, with endless solutions and consistently high quality.
This rigorous process ensures maximum reliability and performance for every MV Marine inflatable boat.
Among the various construction methods of fibrous composite artifacts, those of greatest interest to the marine industry are RTM Light and infusion.
These innovative techniques were developed in aerospace and automotive, and only later applied in the marine industry.
These methodologies make it possible to reduce weights, increase the mechanical properties of artifacts, and reduce the vessel's operating costs.
Due to the constant increase in fuel prices, boaters are very sensitive to the consumption and efficiency of hulls.
This aspect takes a crucial role in today's market, MV marine provides superior performance and “unsurpassed” low operating costs.
Infusion represents an advanced vacuum processing technique, successfully employed by MV Marine since 2005, used for laminating high-performance structural parts, such as hulls, decks, deckhouses and saddles.
The fibers are dry laid out in the mold, including the sandwich cores, the whole thing is placed under vacuum with a bag. With the vacuum, resin is drawn into the composite, filling only the empty spaces in the fibers, with perfect impregnation, without excess resin. With this technique, a laminate of constant thickness, light weight and the highest quality is obtained.
During this processing, emissions of volatile organic particles (V.O.C.) are reduced by 92 percent; during the catalysis process, volatile solvents remain “trapped” inside the bag that seals the mold.
This results in a significant benefit to the working environment and atmospheric emissions.
RTM-Light, which has been used in the production cycle by MV since 2005, is an advanced vacuum closed-mold lamination technique that is ideal for creating exposed parts with a very high degree of finish. Elements such as locker lids, formwork and consoles result in gelcoat gloss on both faces.
Compared to infusion, RTM-Light is more complex and requires the use of mold, counter mold and foam cores with specific tolerances. The great advantage of RTM-Light is in making complex components, such as the stern hatch of the Mito 45. Due to the use of the foam core, these elements are both rigid and lightweight. This type allows very high levels of finishing and reduces production time. The manufactured parts are already finished and, after simple trimming, are ready for assembly, reducing atmospheric inputs and cutting dust.
Comparing the vacuum lamination techniques used by MV Marine - Infusion and RTM-Light - with the manual lamination method, widely used in the marine industry, cutting dust is reduced by 80 percent and the weight of GRP parts is reduced by 50 percent.
Moreover, thanks to RTM, the inner and outer surfaces of fabricated components have an optimal polished Gelcoat finish.
Additional Advantages:
-95% Volatile Organic Compound (VOC) ;
- +70% tensile strength;
- +38% flexural strength;
- Prevention and protection from osmosis;
- Constant thickness of artifacts.
The stresses caused by wave motion, are carried back on board to the detriment of the crew's comfort, stress-induced stresses, create cracks and sometimes serious structural breaks.
To overcome these problems, Mv Marine's technical staff has designed and tested a new construction criterion for its boats. The shipyard's long experience over the years, making the GRP parts with the innovative methods of full-sandwich, allows for self-supporting hulls and decks, were the necessary elements to consider eliminating the frame, something unusual in the marine industry.
By eliminating the frame, it is necessary to connect the hull to the deck. To do this, it was necessary to revise the concept of the deck, no longer an enclosing element but a structural element, complete with lockers and invaders, where tanks, systems and everything possible are mounted, and then assembled to the hull and saddles.
With this new design, the hull and deck can be connected together through elastic sealants of appropriate thickness and consistency to create a bed of springs, which has the function of dampening the stresses between the two components. Wave stresses are absorbed and dampened by the entire structure, ensuring optimum comfort and reducing any structural cracks or breaks.
