Systemy ewakuacyjne morskich instalacji wiertniczych i produkcyjnych - problemy operacyjne
(Wydawnictwa AGH, 2011) Abramowicz-Gerigk, Teresa; Burciu, Zbigniew
The paper presents operational problems of evacuation systems used on board offshore drilling and production installations, especially with respect to the final stage of evacuation process. The systems characteristics influencing the evacuation process have been described and significance of knowledge of safety characteristics of life saving appliances has been emphasised. The safety function for the life raft has been proposed.
Współczesne wyzwania eksploatacji oceanicznych kopalin polimetalicznych
(Wydawnictwa AGH, 2011) Abramowski, Tomasz; Kotliński, Ryszard A.
UE countries are in the face of shortage of some metal mineral deposits which are essential for the development of many branches of industry, e.g. Ni, Co and RE. One of the strategic demand for UE development is the securing of balanced access to metal ore resources. Ocean mineral deposits have potential for the future and they contain several scarce strategic metals, recognized by the UE in June 2010 as crucial. In the group of 14 raw materials connected with the risk of supply deficiency are such resources as: rare earth elements, niobium, tantalum, platinum family metals, cobalt, gallium, germanium, indium, manganese, tungsten. The time forming relations of metals revealed on the basis of regional metallogenic analysis indicate that the characteristics of distribution and geological and mining conditions of polymetallic ore resources and metals content are regionally different. High potential of ocean polymetallic resources including oxide concentrations Fe-Mn (nodules and cobalt crusts) and massive sulphides is the result of geodynamic processes forming conditions of deposits in different oceans of the World. Mots perspective deposits of polymetallic nodules and cobalt crusts are located in Pacific and Indian Oceans and massive sulphides in Pacific, Indian and Atlantic Oceans. There is very high content of metals recognized as deficient in European countries (Mn, Co, Ni, Ti, REE, Pt).
Eksploatacja złóż polimetalicznych konkrecji z dna oceanu
(Wydawnictwa AGH, 2011) Abramowski, Tomasz; Szelangiewicz, Tadeusz
Polymetallic nodules discovered in 19th century become the potential resources of the metal ore. Very large depths, the possibility of harsh weather conditions and long distances to the shore causes that the exploitation at industry scale becomes the technically difficult and expensive venture. In the paper several different concepts for nodule mining systems together with problems which have to be solved before exploitation were presented.
Systemy pozycjonowania oraz podkład kartograficzny wykorzystywane w operacjach »offshore« na przykładzie rozwiązań firmy Fugro
(Wydawnictwa AGH, 2011) Bąk, Andrzej
The main specialist positioning systems used in offshore operations are described in the article. Their properties were analyzed as well as visualization methods of spatial information. Also ECDIS systems were compared to those used in offshore industry pointing the crucial differnces between them.
Możliwości wykorzystania Dolnej Wisły do celów transportowych
(Wydawnictwa AGH, 2011) Bolt, Adam; Jerzyło, Patrycja
The water transport is cheapest, safest and least troublesome for the natural environment. Restoring the regular goods navigation will result behind himself in the revitalization existing and construction of new infrastructure handling-logistic of inland commercial ports. Creating the transport policy, it is necessary to remember that the water transport is the most ecological type of transport. He is producing the 10% of the emissions of gases expelled to the atmosphere by the equivalent wheeled transport scarcely. His energy consumption is a 30% of the energy consumption of the wheeled transport. A characterization of the Lower Vistula was included in the article, concept of development of the watercourse at the part Bydgoszcz - Gdańsk. Barriers hindering the development of the water transport and argumentation speaking for the activation of watercourses in Poland are presented. An alternative transport was described for carriages of cargo overland. The Lower Vistula constitutes the very important length for the inland waterway shipping. He constitutes the part of international E40 watercourses and E70 as well as Gdańsk and Gdynia can fulfill the transport important function for bulk goods or in containers at the part from the center of Poland to ports. The presented watercourse of the Vistula, as the chain in the all-Polish transport network with using container terminals on existing wharves in the Port Gdańsk and with new terminal in Bydgoszcz.
