This paper emphasised the importance of proper handling and selection of specialised skimmer equipment for accidental pollution with oils. The research was motivated by the lack of similar papers that offer an extensive and recent literature analysis related to the use of skimmers, with the ultimate aim to present the methodology for proper selection of appropriate pollution equipment. Knowledge on the equipment characteristics such as capacity, selectivity, speed, and pump power of the skimmer is essential for efficient and fast collection of spills. The study aimed to calculate the oil collection rate of an individual skimmer device with different pumps. The classification of skimmers, pumps, and collecting tanks was made according to their main features. The results showed the correlation between pump capacity and the skimmers. Due to the complexity of mechanical equipment and various devices, it was crucial to identify and connect the skimmer with the proper pump. For these reasons, the authors proposed a model which determines the optimal combination for thirteen skimmers and eleven pumps. The model can help shorten the time of collecting oil from the sea surface and provide a more efficient and smoother response in the events of accidental marine pollution.

“…Fatores ambientais, como: a exposição severa aos raios ultravioleta, associados degradação, fotodegradação da matriz polimérica ou a montagem do reparo próximo a equipamentos rotativos, que pode gerar degradação mecânica pelo mecanismo de fadiga, pode diminuir significativamente a vida útil do reparo a longo prazo (RUBINO et al, 2020;YELESWARAPU et al, 2021;ZHANG et al, 2022).…”

A continuidade da demanda por petróleo no cenário mundial a médio prazo implica na perseverança da indústria petrolífera no Brasil, bem como estimula a criação de novas tecnologias para a manutenção das plantas de processamento offshore. Com intuito de diminuir a presença de fontes de ignição em plantas de hidrocarboneto, o segmento industrial vem desenvolvendo alternativas aos reparos soldados com bandagens compostas de material compósito e polimérico. A utilização desses materiais em reparos durante a manutenção corretiva de uma plataforma de petróleo, é algo que pode atenuar os problemas de logística típicos do ambiente offshore. O trabalho tem por objetivo investigar os mecanismos de deterioração e fatores críticos para integridade e reparos de material polimérico e compósito em unidades de processamento primário offshore. Os resultados indicam que, quando aplicado dentro dos parâmetros operacionais e ambientais adequados, esse tipo de reparo pode ser uma alternativa confiável e consistente nos processos de manutenção.

“…These can be found in a variety of hose materials from hose manufacturing companies such as Dunlop Continental Oil and Gas, Yokohama and Trelleborg, among others [44][45][46][47][48]. One challenge with using marine hoses is the assessment of fatigue load due to their behaviour relative to the utilisation in sea conditions [49]. Figure 1 shows a field deployment of Trelleborg's Sealine floating hose.…”

With the exploration of oil trending deeper, from shallow waters to deep waters, there is a corresponding increase in the need for more sustainable conduit materials for production purposes. Secondly, there is an increasing demand for more energy from fossil fuels that are excavated with less expensive technologies. As such, short-service hoses are applied in the offshore industry. The industry has utilised composites to improve the material and solve different offshore issues. This study analyses a current problem facing the oil and gas industry at present regarding hose usage. This paper presents results from the local design and analyses of a marine bonded composite hose (MBCH), to present its result visualisations and nephographs. In this paper, the local design of a 1 m section of an MBCH was carried out in ANSYS under different loading conditions. Some design criteria were set, and other load conditions were used to simulate the model using the finite element model (FEM) approach. From this study, composites could be considered to improve conventional marine hoses. The findings of the study include the identification of linear wrinkling and damage sites on the helix reinforcement. An experimental investigation and proper content test are recommended for the bonded hose. Additionally, highly reinforced hose ends are recommended in the ends of the MBCH, as they had maximum stress and strain values. It is recommended that hose operations like reeling must be conducted under operational pressure and not design pressure, as the study shows that the design pressure could be high on the hose model.
