2. Recent Events
2.1. On the 18.09.2008 a Framework Agreement was signed between the Bulgarian Ship Hydrodynamics Centre (BSHC) – BAS , Varna , the Vaptsarov Naval Academy – Varna and the Institute of Oceanology (IO) - BAS , Varna for establishment of Regional Centre of Marine Sciences and Technologies .
The establishment of the Centre is under the patronage of the President of the Bulgarian Academy of Science and the District Governor of District of Varna .
The main objective of the Centre is to perform scientific research , training and development of projects in the field of marine ecology , ocean engineering , naval sciences , means, armaments and equipment for the security and defense , shipbuilding , shipping and marine education . Within the frames of the Centre technology transfer should be realized of innovation products as well as exchange of scientific and technical information for the increase of the competitiveness of marine industry in the region and for fulfillment of the Lisbon Strategy for integration of the science and education and for the development of the regional structures . The purpose is that the developed projects will be both with own and external financing including under NATO and the European Union .
One of the first steps is the already undertaken by development of education curricula of the new disciplines “Oceanology and engineering ecology” and “Design, research and operation of platforms and underwater facilities” for training of Bachelors and Masters in the Naval Academy, Varna in the specialty “Ocean Engineering”. In the process of this training it is foreseen to attract not only habilitated scientists from BSHC-BAS and IO-BAS but lecturers from eminent institutions, companies and higher schools in USA, Portugal, Spain, France, Denmark, including Bulgarian scientists and specialists, working abroad .
Information about the new-established Centre for marine sciences and technologies will be published in the newsletter, edited by the International Maritime Association of the Mediterranean (IMAM) .
2.2. On the 13.11.2008 the Bulgarian Ship Hydrodynamics Centre in Varna was visited by Delegation of the People's Government of the Province Zhe-Jian, t he People's Republic of China , lead by Mr. Zhao Hong zhu , Secretary of the Committee of the Chinese Communist Party and Director of the Permanent Committee of the National People's Congress .
The Delegation was accompanied by the Ambassador Extraordinary and Plenipotentiary of t he People's Republic of China in Republic of Bulgaria – HE Mr Zhan Vanxue .
The members of the delegation were thoroughly acquainted with the activity and the scope of the main experimental facilities of the Centre as well as with its wide international R&D cooperation including with Research Institutes from the Province .
The Head of the Delegation was awarded the Honorary symbol of BSHC , accompanied with Diploma as well as advertising materials for BSHC to be distributed in China .
In the Zhe-Jian Province 12 shipyards are working intensively, due to which the Centre may rely on the assignment of applied R&D tasks from the Chinese side .
HE Mr Zhan Vanxue is addressed with kind invitation for assistance in the further enlargement of the cooperation between the two countries in the field of activity of BSHC .
2.3. As of the end of 2008 the necessary documents were prepared for the accreditation for training of PhD students in BSHC-BAS in the scientific specialty 02.15.17 “ Sea Costal and River Hydraulics ” and presented in the CD – BAS and the National Agency for Assessment and Accreditation ( NAAA ). The need for training of young specialists and scientists in this field is the result of the activated in the last years national policy for providing of potential for carrying out of researches of sea coastal and river hydrotechnical facilities for the purposes of the regional p roject s for the development of the Bulgarian Black Sea coast and for protection of the coastal zone and the river valley of the Danube river as well as for preventive actions during extreme phenomena and situations along the coastal line and in the national river system .
