Vaikai dėl įvairių priežasčių, netekę tėvų globos patenka į globos įstaigas, patirdami prieštaringus išgyvenimus, net nesąmoningai reiškia protestą, elgiasi negatyviai. Problemiško, nekontroliuojamo elgesio globos namų auklėtinius šių įstaigų darbuotojai nukreipia į socializacijos centrus. Vaikai, keliaujantys iš vienos institucijos į kitą, tampa tarsi institucinės aukos. Štai toks asmuo, praėjęs kelias skirtingo griežtumo globos institucijas, subręsta ir patenka į suaugusiųjų pasaulį. Jų gyvenimo scenarijus kuriamas ant sutrikdytos (iškreiptos) socializacijos pamato jau nuo ankstyvos vaikystės. Per patirtį įgyta programa nematomai veikia žmogaus gyvenime nepriklausomai nuo pasipriešinimo ir laisvo pasirinkimo. Korekcijos proceso veiksniai galėtų pakreipti buvusių globos namų ir socializacijos centrų auklėtinių gyvenimo scenarijų. Tai įtakotų jų nuostatas savo ir aplinkinių atžvilgiu, kurios susijusios su veiklos perspektyvomis, gyvenimo kokybe bei sėkminga integracija visuomenėje. / The children who have lost their parents due to some reasons get to foster homes. Having gone through different contradictory negative emotions there, they, sometimes even subconsciously, express their protest behaving badly. The children who are uncontrollable and break behavioral norms are directed to socialization centres by social workers. These children who move from one such an organization to another are practically becoming victims of these social institutions. At last, after being in these organizations that can rather differ in their limits of freedom, such a person grows up and becomes an adult. Life scenario of these young people is created on a destorted social basement since their early childhood. The acquired life programme invisibly influences a person’s life through his/her experience independently on any kind of struggle or a free choice. Some activities that correct this process can seriously change life scenario of former students of foster homes and socialization centres. In such a way we can influence their previous perception of themselves and the surrounding world in order to change it because this perseption is directly connected with work with a different perspective, life quality and successful integration in the society.

The aim of this thesis is to evaluate different repowering alternatives from the viewpoint of increasing power production from existing offshore wind farms (OWF), as some of the first commissioned OWFs are approaching the end of their expected lifetime. The thesis presents a literature review of components and financial aspects that are of importance for repowering of OWFs. In the literature review, risks and uncertainties regarding repowering are also lifted and analysed. The thesis contains a case study on Horns Rev 1 OWF, where three different repowering scenarios are evaluated by technical and financial performance, aiming to compare the cost of repowering alternatives. The design of the case study is based around previous studies of offshore repowering having focused mainly on achieving the lowest possible levelized cost of energy (LCoE) and highest possible capacity factor, often resulting in suggested repowering utilizing smaller wind turbines than the existing ones. In order to evaluate the financial viability of repowering alternatives, the software RETScreen Expert was used to estimate the annual energy production (AEP) after losses and calculate the net present value (NPV) and LCoE for lifetime extension and full repowering utilizing different capacity wind turbines. Input values from the literature as well as real wind resource measurements from the site was utilized to achieve as accurate results as possible. The result of the case study shows that repowering of OWFs have the possibility of providing a very strong business case with all scenarios resulting in a positive NPV as well as lower LCoE than the benchmarked electricity production price. Although the initial investment cost of the different repowering alternatives presented in this thesis still are uncertain to some extent, due to the lack of reliable costs for repowering alternatives, this thesis provides a base for further research regarding the repowering of OWFs.
