Sustainability, Environment and Economize Automatic Systems: Chantier Navale de Marseille (CNM) prepare next steps to be the first European Green-Shipyard.
CNM work with a state-of-the-art technology for blasting and coating of hulls developed by Hubert Palfinger Technologies (HPT).
The new, cost-saving process, the Hull Treatment Carrier (HTC), sets new standards in coating quality and efficiency to make a sustainable contribution to environmental and occupational safety. HTC is now available at CNM customers for all repair and refit projects.
Removal with ultra-high-pressure water blasting up to 3,000 bar, automated application up to 1,200 m. per hour per HTC, up to 30 percent less coating needed - CNM, in cooperation with Hubert Palfinger Technologies, is setting the stage for new standards in the refit and repair sector by introducing to the market with new HTC systems for surface treatment and color application.
Hubert Palfinger and his team develop and built the first eco-friendly, cost-optimized and automated system for maintaining ship surfaces. Until now, no automation took place in the field of ship maintenance and ship repair. Washing, Blasting and Coating hulls meant three standalone processes, resulting in hundreds of man-hours. With the dual setup the HTC (Hull Treatment Carrier) is able to simultaneously blast and coat the hull, maximizing time efficiency and minimizing costs for shipowners and shipyards.
The „Rise of the Machines" may be ominous to some, but in the shipping industry the rise of automation is a welcome innovation. Continuing advancements in automation have led to — in most cases — increased productivity, efficiency, reliability and confidence in maintenance.
Manual work can‘t guarantee constant daily positive constitutional or working quality of employees! Manual work can‘t guarantee constant surface preparation and coating thickness!
The biggest Automatization Benefits are the effect with reducing the roughness depth of a vessel with surface preparation, coating and consistent coating. Automation help us report more accurate results, more quickly. These faster and more accurate results will improve material consumption and environment.
Compared to common manual application techniques, with the HTC, due to the automatic surface preparation and coating, an exact and uniform color composition can be achieved. This results in reduced consumption of the color coating as well as a smoother application of the antifouling (AHR) providing a less rough surface, which ultimately leads to fuel savings when the ship is in operation.
According to the Admiralty formula an increases of speed at 18 knots to 19 knots will require (19kn)³ / (18kn)³ = 17% more engine power, thus fuel consumption. If this is achieved by better hull surface condition and not by additional engine power, approx. 17% of fuel can be saved. In general, for every 25 µm (25/1000 mm) increase of the average hull roughness, the result will be a power increase of 2-3%, or a ship speed reduction of about 1%.
Chantier Naval de Marseille opened in October a new giant facility, the Dry dock no. 10, the biggest dock in the Mediterranean area and one of the biggest in the world.
Forme 10, Operated by Chantier Naval de Marseille (CNdM), is ready to accommodate all types of naval vessels, including those exceeding 270 meters of length, thanks to its 465 meters in length and 85 meters in width.
With the new facility, the shipyard is able to position itself and the port of Marseille as a state of the art location for all ship-owners and cruise ships, tankers, cargo ships, RO/RO, container ships and offshore platforms will all be able to benefit from the extensive expertise and state of the art technologies of the yard. About 10 million euro investments have been planned to increase the shipyard’s efficiency.
Among CNdM activities, a special focus is given to operations linked to the optimization of energy efficiency and environmental performances of cruise ships, in line with the new regulations and cruise lines investments strategies.
“It is a great satisfaction for our Company to see Forme 10 finally fully operational as we have always believed in the great potential of this facility. The availability of Forme 10 marks a turning point in the operations of Chantier Naval de Marseille, which now has all it takes to become the point of reference in the Mediterranean area for ship repair, maintenance and conversion.” said Ferdinando Garrè, CEO of San Giorgio del Porto, parent company of CNdM and headquartered in Genoa, Italy. “This was made possible thanks to a series of investments that aimed at expanding our business to new market segments and, subsequently, at increasing the efficiency of the shipyard with the best available technologies.
The port of Marseille Fos is the first French port and plays a major role in the Mediterranean Sea. The size of the new ships requires dry docks of adequate measures and in proximity of their area
of operation. Dry dock no. 10 responds to this need and opens new industrial perspectives to large scale ship repair, offering new opportunities for the offshore sector, gas tankers, bulk carriers or container ships. CNdM can now offer their customers, on the same premises, a complete port service, from commercial operations to major repair and refit activities, in a unique industrial pole in the Western Mediterranean.
Works to restore dock no. 10 started in mid-2013 and included the construction of a new floating concrete gate, the overhaul of the pumping system, the repair of the lifting facilities and the redesign of all networks.
About Hubert Palfinger Technologies
As an internationally active company in the special segment of unique machine construction, Hubert Palfinger Technologies (HPT) actively supports the sustainable future of the shipping and offshore industry. HPT's product portfolio includes the development, manufacture and distribution of automated access and maintenance systems. The most important goal for Hubert Palfinger Technologies is with the highest quality of automated coating; to reduce fuel, therefore the overspray and carbon dioxide emissions (CO2) from a vessel to save the environment.
About Chantier Navale de Marseille
CNdM was founded in April 2010 by San Giorgio del Porto to operate dry-docks No. 8 and 9 of GPMM - Grand Port Maritime de Marseille (Marseille Port Authority) and from 2017 dry-dock No. 10, the biggest graving dock in the Mediterranean sea. Despite its relatively young age, the yard draws on a long and venerable legacy. Indeed, with over 175 years of services and craftsmanship, Marseille has positioned itself as an expert venue for ship repair, maintenance and conversion. Over the past century, the architecture of companies and facilities has changed considerably as the environment adjusts to the market. CNdM, employs 140 people including naval architects and mechanical engineers, skilled workers and specialized technicians. The yard is located in the eastern section of the Port of Marseille, the largest in France, in the center of a large traffic zone extending from Genoa to Barcelona. The harbor benefits from direct access to the western Mediterranean Sea with no tideor lock restrictions, which means vessels up to 11.70m can enter CNdM docks with no time constraints.
The area enjoys a favorable climate for ship repair activities, with an average of less than 60 days of rain per year.
