[en] MANAGEMENT MODEL FOR THE IMPLEMENTATION OF A CENTER TO PROVIDE INTEGRATED OFFSHORE LOGISTICS / [pt] MODELO DE GESTÃO PARA IMPLANTAÇÃO DE UM CENTRO DE PROVIMENTO LOGÍSTICO OFFSHORE INTEGRADOALAN FIRMINO GUERRA DE OLIVEIRA 13 May 2015 (has links)
[pt] A indústria de Petróleo enfrenta uma nova realidade com foco na integração
de pessoas, processos e tecnologias, que possibilita a tomada de decisão de forma
mais rápida e consequente otimização da operação, emergindo assim o conceito
de Operações Integradas. Neste âmbito, as principais empresas mundiais desta
indústria possuem programas dedicados à integração operacional da sua cadeia.
Os primeiros ambientes criados eram simplesmente derivados do conceito de salas
de controle operacional, onde a equipe podia monitorar a operação e realizar
comunicação com o pessoal localizado remotamente. Atualmente, as empresas
reconhecem que, além do valor agregado dos ambientes de colaboração
integrados, a integração operacional exige cuidado, avaliação, design e
planejamento da implementação, para garantir que esses ambientes se tornem uma
plataforma para melhorar a comunicação, subsidiar as melhores decisões, permitir
alta qualidade das análises e efetivamente usar um pool de recursos especialistas
para suportar diversas operações simultaneamente. Com base neste contexto, o
objetivo desta dissertação é apresentar um modelo de gestão para implantação de
um centro de provimento logístico offshore integrado. O modelo foi proposto com
base em uma pesquisa-ação realizada em uma unidade de um importante player
da indústria de petróleo. O trabalho ressalta os principais motivadores,
abordagens, vantagens e desvantagens, indicadores de desempenho que podem ser
constituídos, riscos e demais fatores críticos na adoção do modelo de gestão de
um centro de provimento logístico offshore integrado. O modelo foi elaborado de
forma a ser uma abordagem de gestão eficiente para a mitigação das principais
causas de variação nos processos logístico da empresa analisada. A adoção de um
modelo como o proposto representa uma ruptura em detrimento às práticas de
gestão atuais na maioria das empresas, e, portanto, abordagens não convencionais
de gestão de riscos e gestão da mudança são salientadas na dissertação. Por fim,
questões inerentes ao delineamento do modelo conceitual para um modelo que se
aproxime da realidade para a implantação são abordadas e analisadas. / [en] The oil industry has been facing a new reality and its focus lies in people s
integration, processes and technologies which enable decisions to be taken in a
faster way, which optimizes the operation and originates, therefore, the Integrated
Operation concept. Taking this scenario into account, the main worldwide
companies related to this industry are ready to offer programs which are dedicated
to the operational integration of this chain. The first environments stemmed from
the concept of the operational control rooms, where the team could monitor the
operation and perform communication remotely. Nowadays, companies recognize
that, besides the integrated value of the integrated collaboration environments, the
operation integration demands care, evaluation, design and implementation
planning in order to guarantee that such environments can become a platform
which will improve communication, subsidize the best decisions, allow high
quality in the analysis and use a pool of expert resources in an efficient manner in
order to support several operations simultaneously. Based on this context, the aim
of this work is to present a management model for the implementation of a center
to provide integrated offshore logistics. The model was proposed based on an
action research carried out in an important player unit of the oil industry. The
work highlights the main motivations, approaches, advantages and disadvantages,
performance indicators which may be constituted, risks as well as other critical
factors in the adoption of a management model for the implementation of a center
to provide integrated offshore logistics. The model was created with the aim of
becoming an efficient management approach for the mitigation of the main
variation causes in the logistic processes taking the company analyzed as a
reference. The adoption of a model as the one proposed represents a rupture as
opposed to the current management practices in most companies, and, therefore,
non-conventional approaches in the management of risks and changes are
highlighted in this work. Finally, issues inherent to the formulation of the
conceptual model for a model which is close to the reality for the implementation
are discussed an analyzed.

Improved mine cooling system performance through the control of auxiliary systems / W. BornmanBornman, Waldo January 2012 (has links)
Industrial and mining sectors are amongst the largest single energy consumers in South
Africa, making them a primary focus for implementing energy saving initiatives.
Refrigeration systems on mines are responsible for consuming up to25 % of the electrical
energy consumption on a typical South African deep level mine. Ample opportunities to
reduce the energy consumption of these systems exists, as many of the current systems rely
on old technology and function under partial or inadequate control management.
In compiling this thesis, various energy saving strategies on deep level mines were
investigated. In specific, the effects of controlling and improving the cooling auxiliaries.
Scenarios were investigated and simulated, where after an optimum solution was
implemented. Implementations, such as the ones covered in this dissertation, form part of the
IDM (Integrated Demand Management) energy efficiency incentive introduced by Eskom,
where funding is made available based on actual power saving; ensuring that the projects will
be financially viable to the clients.
Reduced electrical energy consumption realised from the abovementioned projects were
measured, captured and compared to the consumption before project implementation to
determine the achieved savings. Savings of up to 30 % of the plant installed capacity were
realised, providing average savings of up to 2.3 MW per day. / Thesis (MIng (Mechanical Engineering))--North-West University, Potchefstroom Campus, 2013
