Procedure of repair pipeline at dead plate
Borek, Jan ; Opletal, Jan (referee) ; Kubíček, Jaroslav (advisor)
This thesis is focused on a crudeoil pipeline repair technology at the dead plate. The thesis is devided into 4 basic parts (chapters). The openning chapter describes reasons for performing regular pipeline inspections regarding pipeline's defects and technology of defects repair. The second chapter is devoted to the particular repair technology - cut out of a damaged pipeline part and its replacement by a new pipeline piece - with a detail description of preliminary and consenquential assembly activities (safety and environmental aspects). This chapter also comprises a list of documents confirming technical qualification and readiness for repairs execution. The third chapter is aimed at proposition and verification of the welding method by means of non-destructive and destructive testing of a test circumferential weld according to the proposed weld procedure specification – WPS. There are presented the results of particular tests and complex evaluation of the welding process design by the inspection organization. The last, fourth chapter deals with a calculation of general costs of repair execution which is an important part of a final pricing.

Technology of Trenchless Rehabilitation of Pipelines
Pleva, Ondřej ; Fic, Miloslav (referee) ; Kárník, Jan (advisor)
Contend of bachelor thesis is aimed on trenchless methods of rehabilitation underground pipe networks. It includes several repairs, renovations and replacements without need of open cut. At its beginning, thesis is focused on classification of different types of pipe defects, their localization and cleaning methods. Mentioned activities are in most cases essential part of pipe rehabilitation. Main part of thesis is dedicated to detail description of individual rehabilitation methods. At the end the aim of the thesis moves toward assessment and cooperation of trenchless methods in relation one to another and also in relation to open cut.
