RICERCA / SPERIMENTAZIONE PROGETTAZIONE / COSTRUZIONE IMBARCAZIONI MILITARI,
PROFESSIONALI STRUTTURE IN MATERIALI COMPOSITI AVANZATI

La Stemar Nautica è nata quale divisione nautica dell’Azienda della famiglia Marcelli, società operante dal 1880 nel campo della protezione ambientale e organizzazione ed ottimizzazione delle risorse naturali.

Sotto la guida di Alessandro Marcelli opera con l’intento di produrre una nuova generazione di imbarcazioni professionali: strutturalmente più robuste, più leggere, più veloci e con costi operativi inferiori.

Per raggiungere questo obiettivo è stato costruito un nuovo cantiere dotato delle più moderne attrezzature, macchine operatrici e sofisticati software CAD 3D e CAM per la realizzazione di modelli e stampi.

Un team di ingegneri, architetti e tecnici altamente qualificati, specializzati in compositi avanzati, sono in grado di studiare, progettare e realizzare qualsiasi tipo si struttura, fornendo prodotti “custom made” chiavi in mano.

Il cantiere costruisce le sue imbarcazioni in composito avanzato, il medesimo utilizzato per la costruzione di barche a vela da regata e molti motoscafi off-shore partecipanti al Campionato del Mondo.

Tutte le imbarcazioni sono realizzate in base alle specifiche esigenze operative dei Clienti, garantite a vita contro fenomeni osmotici, studiate e progettate, anche come piattaforme tecnologiche multi-ruolo con e senza equipaggio, fornendo un’ampia gamma di: profili di missione, autonomie, protezioni balistiche ed attrezzature specializzate funzionali alle diverse esigenze operative.

R&D – ADVANCED COMPOSITE MATERIALS PROCESSING METHODS BEST PRODUCT COMPETITIVE PRICE

Stemar Nautica was founded as Marine Division of Marcelli’s group of Company. The family is operating since 1880 in the environment protection and natural resourcefields.

Under the leadership of Alessandro Marcelli is operating with the intent to produce a new generation of military and professional boats: stronger, lighter, faster runnig and with lower operational costs.

To achieve this objective it was built a new shipyard with the most modern equipment, machinery and sophisticated 3D CAD and CAM software for the construction of models and molds.

A team of engineers, architects and highly qualified technicians, specialized in advanced composites, are able to study, design and build any type of structure, providing products “custom made” turn keys.

The shipyard builds its boats in advanced composite used for the construction of Racing sailboats and many off-shore speedboats participating in the World Championship.

Our boats are “custom made”with a lifetime guarantee against “osmose”, also designed as a multi-role technology platforms, providing a wide range of: mission profiles, autonomy, adaptability, ballistic protection and specialized equipment for any operational requirements.

STEMAR ADVANTAGES

The advantages offered by STEMAR products:

WEIGHT REDUCTION

Less power required
Better overall performances
Lower fuel consumption
Increased operational range.

BETTER STIFFNESS & STRENGHT FOR SAFETY NAVIGATION AT HIGHT SPEED ON ROUGH SEA

Controlled temperature room up to + 85° C and 20% humidity for epoxy resin processing A temperature-controlled room for resin’s storage.

EXPERTISE AND CERTIFICATION

Company consultant:

University of Perugia faculty of Engineering

Quality certifications:

ISO 9001:2008 certification from DQS ITALY – Professional boat design and construction

MATERIALS AND WORKING METHODS

To achieve best results of lightness and strength below specified, the shipyard
uses only:

epoxy resin (which has multiple and ultra resistant molecular bonds)
“vacuum bag” lamination to give 100% of a perfect cohesion between the layers of reinforcement and maximum lightness.

PRODUCTION STAGES

STEMAR can satisfy the entire production cycle including:

PROJECT

Understanding of customer requirement;
Worldwide research for boats having similar specification;
Selecting the best solutions;
Design of a new boat that has all the best solutions plus STEMAR materials and construction processes.
