Maritime is a very competitive industry in global market. In addition to political, economic and prosperity, container carriers have to confront oil prices and climate. It gets high risk and uncertainty in operation. The threat of oversupply of capacity will affect the operation and development of container carriers. Costs is aggravated on container carriers due to they brought too many new vessels when previous boom but economic declined soon. Fleet deployment is a big issue when making operational strategies and plans. Container carriers have to plan how to purchase and lease vessels. People said that the proportion of owned container vessels of Europe container carriers is lower than Asia container carriers. Europe container carries may not spend too much cost to purchase container vessels so it would be more flexible to lease container vessels and able to deploy container vessels in/out of route and create brand new service more mobility. For this reason, operating performance is better than Asia container carriers. This study is base on secondary data from Alphaliner, Containerisation International and American Shipper database and periodical in 2007 and 2008: net profit, total revenue, the numbers of owned, leased and operated container vessels. The 15 major container carriers are divided into three segments: Asia-Chinese, Asia-Non-Chinese and Non-Asia container carriers. The General Linear Mode is practiced on these to find out if any impact or correlation from the proportion of owned container vessel to performance. The conclusions of this study are as following. 1. It¡¦s no correlation between the proportion of owned container vessels and net profit and total revenue in 2007 and 2008 2. The proportion of owned container vessels can not be fixed at a value 3. The proportion of owned container vessels is dynamic, may not be operated by container carriers.

This diploma thesis is engaged in the analysis of a safety mechanism, which is a part of a truck trailer. This mechanism provides a safe and firm connection of a container to the trailer. Primarily abroll containers according to German standard DIN 30 722 are being transported. The introductory part of the thesis deals with the current traffic condition and the accident rate in the Czech Republic. Legislative requirements for safety elements of trailer technology for road transportation are further defined. They are followed by a recherche of industrial solutions for securing mechanisms. Consequently calculations to obtain necessary securing force were performed. An analysis of the mechanism kinematics was carried out then. A structural check of selected mechanism elements was carried out following the kinematics check. Further, an optimalization of a transom design was carried out followed by another structural check. The structural checks were carried out using both the analytical method and the finite element method. In conclusion design documentation was elaborated. This diploma thesis was elaborated in cooperation with the SVAN Chrudim s.r.o.

This diploma thesis is focused on container safety mechanism which is a part of truck trailers. It designs pneumatic – mechanical safety mechanism suitable for safe transport of container with driving drum which are produced according to German standard DIN 30 722. It concerns containers with total weight of 22 tons. The first part of this thesis is focused on evaluation of possible load by common operating conditions. The technique of mechanism design is introdiced in several developing stages from original solution to final version. The final version processes all force and kinetic aspects. Selected parts of safety mechanism are controlled from solidity perspective. Some calculations and analysis were processed both by convention method and method of final elements on PC. Thesis was created in close cooperation with company SVAN Chrudim, s.r.o.
