Workshop on offshore technologies for Aquaculturevenue: Technion, Haifa organizers: contacts:
Description: Workshop on Offshore Technologies for Aquaculture We are organizing a workshop as described in continuation. The workshop will be held in the Faculty of Mechanical Engineering, the Technion, Haifa. The deadlines for presentations are:
All papers will be reviewed by a committee. The registration fees, in ECU , are:
1 - Covers preprints, reception, coffee breaks, lunches. 2 - Covers coffee breaks. Requires presentation of student ID. 3 - Covers coffee breaks and one lunch. Area is available for hire to exhibit posters or scale models of systems. Advertisements can be included in the volume of preprints. Fees upon inquiry. Special rates for participants are offered by some hotels in Haifa, as exemplified below. Please book directly mentioning registration for the workshop. Dan Panorama --- Haifa --- A contemporary-style tower that commands superb views of the
city and the verdant Galilee, reaching as far as the crusader city of Acre. The hotel
features a choice of fine restaurants, a disco, and an adjoining mall. The Nof Hotel --- Sits in a magnificent location overlooking a breathtaking view of the
city and the Haifa Bay. Hotel Shulamit --- Located in a quiet residential area, within 10 minutes of drive from
the Technion campus. Cozy rooms. Dvir Hotel --- The name of the street on which the hotel is situated, Yefe Nof, that is
Beautiful View, aptly describes the environment. In this quiet street you will find the
Dvir Hotel with its tranquil atmosphere, yet only a short distance from the Carmel Centre,
one of Haifa's major business and entertainment centers. In Eilat, discount prices at Edomit Hotel, in tourist centre and close to beach. Single room and breakfast, 60 $, double room and breakfast, 70 $. Tel. 972-7-6379511. We hope that you are interested in participating and would greatly appreciate it if you will complete the attached form and return it, as soon as possible, at the indicated address.

Workshop Offshore technologies for mariculture The workshop refers in the first place to equipment for offshore fish farming in exposed locations. Experience shows that fish grow faster and healthier in open-sea locations where better circulation enhances both the supply of oxygen and the dispersal of pollutants. Thus, negative impact on the environment is avoided. Another advantage of open-sea fish farms is that being remote from the shore they do not intrude into the local seascape and interfere less with bathing beaches, tourism and urban development. Moving fish farms towards the open sea is a desired aim for countries in which sea aquaculture began in protected areas, such as fjords, lochs, or behind islands. Open-sea fish farming is the only option for countries that have no protected sites; this is the case along the Mediterranean coast of some South European, North African and Middle-East countries. On the other hand, the progress of open-sea mariculture is slowed by several problems. The most serious difficulties are:
Collision with intruding vessels can cause cage failure and endanger the fish. Farmers are looking forward towards advanced technological means for solving the above problems at reasonable costs. Research institutions are devising and developing such means, and manufacturers are making efforts to offer marketable solutions. Thus, fish cages for open-sea locations are high-tech products that result from many years of research, involved CAD and were tested in ship-model basins. Some manufacturing enterprises had a previous, long experience in offshore technology. To solve the problems of cage supervision, fish monitoring and regular food supply some farmers used service vessels moored in the neighbourhood, others preferred service platforms that can accommodate a crew, fish-feed silos, feed distribution equipment, and monitoring instrumentation. Besides cages and moored vessels or platforms, the operation of sea cages requires service vessels for land-to-sea and sea-to-land transportation, underwater unmanned vehicles (UUV), equipment for underwater vision and sea-to-shore data-transmission systems. Local supervision systems placed on buoys have also been used. The future of open-sea mariculture heavily depends on suitable equipment in the categories enumerated above. Many solutions can come from the field of offshore technology where they have been developed and successfully experienced. We think that open and sustained discussions between all parties involved can greatly contribute to progress. Therefore, the workshop is meant to bring together those factors. Fish farmers will define their problems and describe their experience. Naval Architects and Ocean Engineers will lecture about the scientific and technological background of the problems and will explain how advanced engineering can help them. Manufacturers will present their solutions. Engineers and researchers from other fields can contribute to a better understanding of new materials and instrumentation. The character of the workshop Regular conferences are characterized by short lectures about innovations, followed by still shorter discussions within which very few questions are asked and briefly answered. The workshop will differ from those conferences in the aspects detailed below. - Some lectures will be tutorials covering subjects such as the description of real seas, strength problems of equipment subjected to high-sea loads, mooring design, materials for marine equipment, and advanced instrumentation. The tutorials are meant to help fish farmers in better understanding their problems and the possibilities of coping with them. Also, the tutorials will help farmers to specify better the equipment and the overall farm concept they may want to order. - In a special session farmers will expose their problems and formulate their desires to an audience consisting of researchers and of manufacturers of equipment. The emphasis is on what farmers want, and in giving researchers and suppliers something to think about for new designs. - Instead of short discussions we envisage open panels and live brain-storming sessions. - One product of the workshop can be the identification of problems and the stimulation of researchers and manufacturers to solve them. We hope that another result will be the formation of partnerships aimed at solving a specific problem or developing a desired product. - A volume of proceedings of the workshop and one of discussions will present the most advanced technologies and will define crucial problems and their suggested solutions. Depending on the number of registered participants, we suggest a three to four-day workshop. The main organizer is the Faculty of Mechanical Engineering of the Technion - Israel Institute of Technology. The Faculty of Mechanical Engineering has a program of Ship Engineering within which several Naval Architects are active. These specialists are well acquainted with Ocean-Engineering solutions applicable in open-sea fish farming. Another Technion faculty that cooperates is the Faculty of Agricultural Engineering. This faculty has been involved since 1990 in R\&D work on offshore fish farming and has a still longer background in land-based aquaculture. The second partner is Israel Oceanographic and Limnological Research. As the name says, this institute has carried out important oceanographic research and measurements over many years. Most important, the institute has a branch in Eilat, The National Center for Mariculture, that has been the key factor in the development of mariculture in Israel. We propose that, following the workshop, a study tour will be organized at Eilat. This tour will allow the visitors to appreciate the achievements of the National Center for Mariculture and of the two local farms, Ardag and Dag Suf.
