Chaired by Francesco Noschese Frigate Class F125 - An Innovative Platform for the German Navy Dipl.-Ing. Andre Averhoff, Blohm + Voss Naval GmbH, Germany The German Navy requires frigates which are designed for participation in international peace keeping missions. The frigate class F125 follows the new conception of the armed forces answering challenging questions. To meet the operational requirements the reduced crew concept and the intensive use concept were developed. These are the main design drivers for platform design along with concepts such as integration of Special Forces and survivability. Compared to the smaller sized frigate class F124 the intensive use profile entails cumulative requirements in terms of system design such as an enlarged deployment period of 24 months, enlarged operational hours of 5,000h per year in conjunction with a reduced crew of 120 sailors. To meet those challenging requirements an expert group of of German industry, procurement office and navy is established to ensure the frigates capability and to monitor the verification process of intensive use capabilities. This is done during design, construction and acceptance tests. Objects of investigation are functional chains, operating procedures and scheduled maintenance. Detailed requirements for availability, reliability, maintainability and supportability have to be proven. Ensuring the platforms capability for intensive use and reduced crew requirements leads to the new Frigate Class F125, which incorporates new innovative concepts and provides the navy with the flexibility needed. New Concept of Patrol Ship System for International Security Dr. Filippo Cucinotta, Univerisità di Messina, Italy Currently the main action areas on international security concern three principal themes: the fight against piracy, protection of the main trade routes and offshore oil plants surveillance. Particularly critical, to the geopolitical balance, are represented by the maritime corridors: Areas like the Strait of Hormuts, by which passes about a fifth of the world crude oil, the English Channel, the Gulf of Aden, the Banda Sea, are sensitive targets that involve high monitoring costs with consequent increases in transportation costs. Even the Mediterranean can become subject of risk, especially for the cruise traffic. In this scenario, it is necessary to rethink the system of surveillance of the seas by focusing on smaller and agiler naval units but coordinated by a central system in order to obtain a single big unit.
The patrols, proposed in this work, have hulls made of composite non-magnetic material to allow the de-mining of sea and equipped with CODOG system to allow patrol and chase velocity very different. Moreover the great technological innovation is, not so much in the weapons system, as in the sophisticated communication and coordination centre. This coordinated system will make security economically competitive by lowering the levels in the risk matrix and reducing insurance premiums for shipping companies. Such a system, coordinated by an International Agency, is the only way to deal with what has been called the new terrorism into “franchising”. Design and Classification of an Amphibious Naval Ship Ing. Nico BRUNI, RINA Services SPA, Italy Commander Mauro Galliussi, Italian Navy, Italy; Eng. Stefano Ferraris, Fincantieri Cantieri Navali Italiani S.p.A., Italy Due to their versatility, Amphibious Naval Ships represent an ideal solution for Navies that are projected in worldwide operation both for military, peace-keeping or humanitarian scopes. In fact, they are characterised by projection capabilities from sea, air and land thanks to the availability of well dock, flight deck and Ro-Ro spaces; when employed in military operations, they can also act as command and control centres. The design of an Amphibious Naval Ship is to be such that it may easily be fitted for all the foreseen operating conditions: helideck and garage spaces are to be used also for vehicle or container transportation, accommodation spaces for troops may be employed as hospital areas in disaster relief, etc. From classification point of view, an Amphibious Naval Ship presents a number of peculiar features that are unique for a military vessel; hull forms, carriage of vehicles and transportation of troops or civilians (when employed in humanitarian missions) constitute a link with merchant Ro-Ro pax ships but military features such as ammunition stores, flight deck, well dock, hangar and refuelling facilities require special consideration. In particular, the presence of a well dock represents a real big issue regarding stability approach and cannot be dealt with standard criteria. This paper aims at giving an overview on a joint approach to the design and classification of such vessels, focused on the need to provide Navies reliable and fully operational ships through the most cost-effective configurations.
