Abstract
New and increasingly demanding requirements of reducing the environmental impact of all types ofships from all countries, along with regulatory institutions like the new "Green Policy" of the EuropeanUnion, leads to the development of a series of regulations/directives, which will immediately affect boththe owner and the builders worldwide. This requires introducing modifications in the vessel design tofulfill these requirements and, ultimately, improve their exploitation while avoiding penalties and/orrestrictions. Awareness of these requirements by some Spanish owners has allowed Spanish shipbuildingto be positioned strategically at the forefront of technology to fulfill these requirements. This work, aftera review of those Directives affecting ship design, focuses on the presentation of the results obtained intwo Ro-Ro Vessels. These vessels, given their design and performances, are a "technological reference"in the new scenario of high environmental performance requirements: Noise and vibrations on board,noise radiated to the harbor, and noise radiated to the water.
Highlights
Growing social interest on the importance of Control, Monitoring, and Improvement of the environment has been the stimulus for different states to respond to this current demand
The appearance of a "totally new requirement" in the Specification of C-509/510 of NAVANTIA-Puerto Real from ACCIONA TRANSMEDITERRÁNEA, that the "Exterior noise level should be under 80 dB(A), measured according to International Organization for Standardization (ISO) 2922/2000 [6] with the vessel
In a general way, vibration levels obtained in both vesels during the sea trials allow us to confirm that the "Dynamic design" in both constructions delivered by NAVANTIAPuerto Real, designed by SENER and calculated by the authors, fulfilled satisfactorily the Specification requirements (ISO 6954/2000 [5]) even being able to opt for a Comfort Class 2
Summary
Growing social interest on the importance of Control, Monitoring, and Improvement of the environment has been the stimulus for different states to respond to this current demand. The appearance of a "totally new requirement" in the Specification of C-509/510 of NAVANTIA-Puerto Real from ACCIONA TRANSMEDITERRÁNEA, that the "Exterior noise level should be under 80 dB(A), measured according to ISO 2922/2000 [6] with the vessel. The reasons for this "new requirement" are two: one is the Operational, that answers the need of the Ship-owner to avoid complaints and fines. Security margins which could be taken as appropriate in noise prediction
