The fishing shipyard in Banda Aceh City is a privately owned shipyard and is managed in a family manner. The shipyard here is active in carrying out maintenance, repair and construction of new ships when there is demand from consumers. The shipyards in Banda Aceh City generally make ships made of wood. The problem that is currently being faced is that there are many abandoned ships due to lack of finance, natural resources, human resources and environment, this is an obstacle to the progress and development of shipyards. The purpose of this study was to determine the inhibiting factors that exist in shipyards in the city of Banda Aceh and find alternative solutions to these problems. The method used in this study was a survey method used to look at existing symptoms and collect data on the factors related to research variables and then analyzed using the Fuzzy AHP method. The results of this study indicate that the financial inhibiting factor is the most influential factor in shipyards with a resulting value of 0.4635, the inhibiting factor of Natural Resources is worth 0.35675, the inhibiting factor of Human Resources is worth 0.2865 and the inhibiting factor from the environment is the inhibiting factor which is the lowest or less influential with a value of 0.14325. The alternative solutions to financial problems are capital loans and investments.An alternative for natural resources is the addition of a minimum stock to anticipate stock scarcity and delays in the delivery of materials and tools. The alternative for human resources is the existence of an office, organizational structure, and division of tasks as well as raising awareness of occupational health and safety.As for the alternatives for the environment, namely the need for buildings or installation of tarpaulins for the areas where ships are built, good land management and studies of other natural impacts.

Shipyard development in Kutaraja Fishing Port is important to improve the port performance. The studies related to shipyards are mainly focused on their productivity, facility layout, production capacity, and management and planning. Meanwhile, there are still limited studies related to the influence of oceanographic factors on shipyard development. This research aimed to identify the impact of oceanographic factors on shipyard industry development in Kutaraja fishing port. The research was conducted from December 2020 to March 2021. The data analyzed in this study were tide, wind, current, wave, bathymetry, and sediment composition. The tide, wind, current, and wave data were collected for the last three years from Meteorology, Climatology, and Geophysical Agency. The current moves from two directions, from northeast and northwest, towards the coastal areas around the eastern part of Kutaraja fishing port, closed to the breakwater. The current in the eastern part moves faster than in the western part, and the western part of the sampling area mostly has shallow waters. The highest tide occurs at 12:00 with a water height of -0.3855 meters, and the lowest tide was at 19:00 with a water height of -1.0485 meters. Fine sand dominated the sediment in the sampling area. The result indicates that oceanographic factors are essential to be incorporated as one of the indicators for shipyard development.

The article characterises the sea-going vessel hull assembly processes and then reviews the existing assembly methods of mechanisms and welded ship structures. Classification of these methods is done with respect to selected criteria of their applicability to hull assembly. Selected methods are used for calculations performed on a model structure and exemplary database. The analysed aspects include the performance of calculation algorithms and the quality of the obtained solutions. Particular attention is paid to the need for reduction of experts’ participation in the planning process due to strong search space explosion effect. The performed analyses have enabled the authors to formulate assumptions for models which would be applicable in real assembly planning in shipyards, as well as to indicate areas of further research which would make it possible to better consider the specificity of production of large-size welded structures.

Content available Kraków – miasto portowe nad Wisłą
PL
Wisła w Krakowie to rzeka żeglowna. Sięgając do historii była najważniejszą drogą komunikacji. Ujście Wisły do Bałtyku zapewniało bezpośredni kontakt z morzem, a tym samym powiązania handlowe bez ograniczeń, z całym światem. Flisacy i włóczykije1 prowadzili barki zwane galarami, co stanowiło ważny element ekonomii i pejzażu miasta. W granicach państwa przed II wojną światową Wisła była powiązana kanałami i rzekami tak z Bałtykiem, jak i z Morzem Czarnym. Zrealizowano częściowo port rzeczny w „Płaszowie”. W Krakowie przed II wojna światową zwodowano dwa pierwsze polskie statki – monitory rzeczne. W okresie budowy Nowej Huty powstał port rzeczny „Kujawy”. W obecnym planowaniu nie myśli się jednak o funkcji portowej miasta i wykorzystaniu nadbrzeży Wisły jako przestrzeni publicznej miasta, a potrzebne jest długofalowe planowanie.

The Wisła in Kraków is a navigable river. If we look back in time has always been the largest river in Poland and the Baltic estuary gave travellers a direct connection to the see and, ipso facto, the possibility of opening trade routs with the whole world. Raftsments and bargees were and important factor in the city’s economi and landscape. Wisła in Poland before the IIWW was connected (by way of rivers and canals) to both the Baltic Sea and the Black Sea. The “Płaszów” river port was partly build befor the IWW. Two river monitors were bulid as the first ships build in a Polish shipyard. In Nowa Huta decided to build a second river port, the “Kujawy” port to material suplly and also be a dock for yachts. There is no trace of ideas reffering to Kraków as a port city in the present development plans. The river can still be saved as a navigable and as a public space but need the complete long-term planning.

The aim of the article is presenting a mathematical model of the assembly process of large-size marine structures. Numerical encoding approach of essential features of the structure and welding methods is proposed. The model takes into account information about the geometry of the connections between elements and their orientation in space during the assembly process. Welding processes are characterized by positions range of their application. The assembly process is shown as a matrix form. Assembly planning is based on the allocation of welding processes into stages and the selection of welding method and assembly position for each stage. It is shown that a lot of such plans can be generated and many of them are unacceptable. Space of feasible plans is defined by set of constraints. These conditions verify that the assembly plan performs a task of welding of all joints and whether it is feasible for particular methods. The methods for calculating the impact of all conditions . an accurate deterministic and randomized approximate are proposed. It is shown that assumed conditions dramatically reduce the set of assembly plans. Moreover, the method of including additional conditions into the model according to the connections making sequence is presented. Sample calculations are shown in two examples . first that is extremely simplified, allowing for a full deterministic analysis of the problem, and a second that is more complex, requiring a partial approximate approach. The article indicates the possibility of using the optimization of the assembly plan. Furthermore, the set of applicable criteria is proposed.

Over the last decades a really tough competitive environment has been observed in shipbuilding sector. Under these circumstances shipyards desire to reduce product cycle time in order to manufacture the product as soon as possible. For this reason it is required to make some alterations in shipyard production system in order to reduce cycle time. In this study a panel fabrication line used in a shipyard, has been considered. The workstations of the panel line have been modeled by using ARENA simulation software and the effects of matrix module assembly on panel line throughput, have been determined.

Content available Design of Inner Gate for CRIST Shipyard Dry Dock
EN
The paper deals with a removable steel inner gate which was designed to separate two parts of a dry dock of about 70 m in width and 380 m in length. The gate allows for independent assembly of ship structures in the two separated parts of the dock. The fore part of the dock can be flooded while the after part is dry. The gate was designed by IDEK Company Ltd in 2011 and it was soon constructed and used by CRIST Shipyard in Gdynia.

Znaczna ilość stoczniowych zakładów produkcyjnych, w tym dużych stoczni, znajduje się w miastach. W Europie jest powszechne, że takie zakłady często są ulokowane w centrach miast lub w ich bliskim sąsiedztwie. Taka lokalizacja stwarza wiele problemów środowiskowych, transportowych i społecznych. Wpływa także na mieszkańców, miasto, jak i na samą stocznię. Identyfikacja tych zależności i problemów (a także sposobów im zapobiegania) pozwoli na lepsze funkcjonowania tego typu zakładów w miastach, ich mniejszą uciążliwość oraz polepszenie relacji pomiędzy stocznią a miastem.

Significant number of shipyard production plants, including large shipyards, ale placed in cities. It is common in Europe that these kinds of plants are located in cities’ centres or nearby. Such localization creates many environmental, transportational and social problems. It also affects citizens, the city and the shipyard itself. Identification of these relationships and problems (and also means of preventing them) will allow better functioning of these kinds of plants in cities, lowering their arduousness and relations improvement between a shipyard and a city.
