Our boat of the year 2011

26 July 2011

We are proud to present the first contribution of BUREAU MAURIC to renewable energy development. The catamaran BIBBY TETHRA is now operating offshore the UK and German coasts for the UK based company "OSIRIS PROJECTS". As reported in preceding news she is a new survey boat aimed mainly at operating in windfarm fields. The seabed mapping in and around windfarm fields is of the utmost importance to find the best way for burying cables and later to check possible cables displacement.

The TETHRA is our second semi SWATH catamaran design, after the JANUS in the years 2000. But the TETHRA is more on the SWATH side than the JANUS is. She is featuring an improved sea keeping and a dual propulsion system to allow operation at very different speeds.. She is full of electronic equipment, multi beam sonar, DGPS, side scan sonar …. The Tethra is DP1, classified BV, and in accordance with MCA workboats code.

We consider the TETHRA is really a breakthrough in Survey catamarans design, being different from all other designs, and we hope a first of a new series of survey cats. Our design team, François Sebilo, the project manager, Jean-Marie Pès the structure engineer, Jocelyne Joly the hull designer, and of course the SOCARENAM shipyard team are all very happy of this realisation. The cooperation with the BIBBY and OSIRIS PROJECTS people was friendly and constructive, showing that designing and building boats in our old Europe is still feasible in reasonable conditions, with reasonable people.

Construction de l'André Malraux

04 April 2011

Le Département des Recherches Archéologiques Sous Marines (le DRASSM), qui s'est récemment illustré par une merveilleuse exposition d'objets d'époque Romaine trouvées dans le Rhône, nous a confié l'architecture de son nouveau bateau "l'André Malraux".

Long de 36 m, pour une largeur de 8,80m, cette unité présente une double propulsion électrique. A côté de la propulsion à hélice pour les transits, le positionnement sur le site de plongée met en oeuvre un Pumpjet Schottel et un propulseur d'étrave. La génération électrique fait appel à 2 groupes électrogènes Baudouin et à un système de convertisseurs Barillec.
Sur le pont, on trouve un portique de 7 tonnes pour des charges, ou bien la manutention d'un sous marin. Des emplacements permettent de stocker un ou deux containers, une installation de plongée complète l'ensemble. On trouve aussi différents équipements, pompe archéo, grue de manutention, etc...
Ce bateau de dimensions raisonnables et de faible coût regroupe donc de multiple systèmes et offre une bonne flexibilité d'emploi, à l'heure où le partage et la capacité d'évolution des navires d'Etat sont essentiels.

Le chantier H2X à La Ciotat a commencé il y a quelques mois, la construction de cette unité en composite avec une technologie évoluée d'infusion de la coque. La construction se poursuit avec l'assemblage des demi-coques et la stratification des raidisseurs internes: une véritable oeuvre en construction composite, qui séduit par sa technologie, son importance, sa beauté.

Bibby Tethra et EDA-R

17 February 2011

Fin d'armement au chantier Socarenam et sous le soleil de Boulogne pour le Bibby Tethra et le premier EDA-R.

En espérant que le temps sera aussi clément pour leurs essais à la mer au printemps...

Euronaval and Maritima boat shows

10 January 2011

Great shows at the end of 2010: Bureau Mauric had booths at both Euronaval and Maritima boat shows

The grand stand at Euronaval was organized around two themes. First, a large "box" with 3D vision featured the work in progress on the VR4D program. This 3D vision experience allowed our visitors to explore a boat both from outside and inside. Great success for what is today in the video games, or movies field, but will be tomorrow a common technique in professional work.

Another attraction was the large model we presented as an innovative concept of OPV. This Drone Carrier Offshore Patrol Vessel (DC OPV) is 70 m long , 28 m wide, with 700m2 of flight deck. It is able to simultaneously implement a drone and a 5 tons class helicopter. A large hangar is able to house a helicopter and a fleet of drones. Her seakeeping surpasses that of comparable monohulls and catamarans .This concept perfectly meets the current operational requirements: control the widest possible sea area with one ship. That is at the best cost/efficiency ratio

Our stand at Maritima was shared with the consortium COCHISE and exhibited the logos of our partners in the work group COCHISE on tomorrow fishing vessels. They gave a good example of what is the concept of an all-electric ship, with electric winches, electric reels and electric propulsion. The energy source is a set of generators, fuel cells, and batteries. A computer continuously adapts the power produced to the power required. Another theme, the versatile multihull dedicated to various fishing techniques except trawling.

The rest of the booth featured the model of the future "André Malraux" for DRASSM- the national maritime archeology department- and the classic activities of Bureau Mauric. We will return soon on this big project in more details.

We also put special emphasis on our involvement in service vessels to wind farms. We are currently building at Socarenam, a catamaran for the survey of windfarms for a british customer.We have also various other projects for windfarms in France and elsewhere
