NAVAL ACCIDENTS CAUSATIVE FACTORS - A BLACK SEA CASE STUDY

(STEF92 Technology, 2021-12-20, Valerian Novac, Gheorghe Stăvărache, Eugen Rusu)

Concerning the volume of goods conveyed, maritime transport is leading, and the last period proved that the trend is ascendant. Increased marine traffic leads to raised accident risks. Despite the state of the art marine technology and consistent regulations regarding navigation safety, naval accidents still occur and produce severe damage to assets, human life, and the marine environment. The paper presents the main types of naval accidents, focusing on the Black Sea basin, a sea with a complicated status regardi...

LONG TERM PREDICTION OF WIND SPEED WITH ARTIFICIAL NEURAL NETWORKS

(STEF92 Technology, 2020-09-20, Gheorghe Stăvărache, Valerian Novac, Sorin Ciortan, Eugen Rusu)

The paper presents a methodology, based on artificial neural networks, for the offshore wind speed values long-term prediction. One of the most available renewable energy is the wind energy. The offshore wind turbines placement presents some benefits comparing with onshore one, like lower environmental impact and long-term stability of surroundings geometry. Of course, there are also drawbacks, like difficult set-up and maintenance or expensive transmission systems for the converted energy. Over all, the off-shore...

SHIP ROUTING IN THE BLACK SEA BASED ON DIJKSTRA ALGORITHM

(STEF92 Technology, 2020-09-20, Valerian Novac, Eugen Rusu, Carmen Gasparotti, Gheorghe Stăvărache)

Show more

In the precursory section of the paper, the authors succinctly present the Black Sea basin's oceanographic features with a focus on factors that can lead to naval accidents. The Black Sea basin is characterized, especially in winter months, by sudden storms, big waves, and winds, seriously affecting the ships and crews' safety. The said basin has also confined areas with pleasure crafts and commercial ships, offshore platforms with accompanying auxiliary fleet and underwater pipes and installations or shallow wate...

ANALYSIS OF THE ENVIRONMENT CHARACTERISTICS INFLUENCE ON WIND POWER WITH ARTIFICIAL NEURAL NETWORKS

(STEF92 Technology, 2019-06-20, Gheorghe Stăvărache)

Show more

The paper presents an analysis methodology, based on artificial neural networks, for the influences of environment characteristics on generated wind power in Republic of Moldavia. The necessity to reduce the pollution, on one hand and the increasing energy consumption on other hand, leads to an extensive use of so called "renewable energy sources" between these the most targeted being wave and wind energy. For the countries without exits to seas or oceans - like Republic of Moldova is - the wind energy remain the ...
