“…The green group refers to the technical-engineering perspective on offshore platforms. Offshore platforms, in fact, are highly complex engineering works that, over the years, have led to several environmental and economic considerations (El-Reedy, 2019). During the activity period, they are a valuable source of wealth by ensuring the extraction of hydrocarbons in the sea but, when the oil field is depleted, these platforms can become challenging structures whose process of decommissioning turns out to be complex and expensive.…”

Purpose This study aims to investigate the collective perception regarding the future of offshore platforms and frame the main categories of meanings associated by the community with the investigated phenomenon. Design/methodology/approach A data driven approach has been conducted. The collection of the peoples’ opinions has been realized on two specific social network communities as follows: Twitter and Instagram. The text mining processes carried out a sentiment and a cluster analysis. Findings The sentiment analysis of the most frequent words has been shown. The following four main homogeneous categories of words are emerged in relation to the decommissioning of offshore platforms: technological areas, green governance (GG), circular economy and socio-economic sphere. Research limitations/implications The alternative use of the offshore platforms, including tourism initiatives, aquaculture, alternative energy generation, hydrogen storage and environmental research, could improve the resilience of communities by offering the development of new jobs and the growth of local and innovative green businesses. Practical implications The adoption of a circular model and GG initiatives aims to limit the input of resources and energy, minimize waste and losses, adopt a sustainable approach and realize new social and territorial value. Originality/value The analysis underlines the importance to adopt a systems perspective, which takes into account the social, economic and environmental system as a whole, the different phenomena that occur and the variety of categories of stakeholders, from users to local governments that participate in the territorial development.

“…It is related to corrosion and potential induced degradation [85]. Because of submerged installation in the sea water environment, algae, marine invertebrates, and other small aquatic species attach and accumulate on the outer surface of submerged offshore structures, causing an increase in their size and changes in other physical properties [86]. Marine FPV systems may be an artificial shelter; therefore, it attracts many birds that can harm the system.…”

The demand for energy has rapidly grown around the world. Solar floating photovoltaic (FPV) systems are an efficient solution to solve the issues from nonrenewable energy sources, such as reduction of CO2 emission, limitation of global warming, environmentally friendly, a great innovation in sustainable aquaculture, and a new ecofriendly technique, along with reducing production costs, especially regarding the scarcity of habitable land. A large number of installation projects using FPV technology have been operated in water bodies such as lakes and dams/reservoirs. However, deployment of FPV offshore is still limited because of the existing characteristics of marine/sea environments that are different from onshore, such as wind loads and wave loads. Despite these difficulties, there are several projects that have been installed in some countries and gained many significant achievements. It opened possibilities to apply FPV systems offshore worldwide. In this review, we present a brief overview of FPV systems both onshore and offshore, analyze advantages and disadvantages of offshore FPV systems, and provide an overview of their future.

“…Vast economic stakes and environmental regulation rule for many countries endowed with coastlines their sailing fleets and offshore oil/gas industry. − Two lines of interest among the technologies deployed in the marine context concern the mitigation of ship emissions through the design of onboard scrubbers that are resilient to swell perturbations and the quest for intensification strategies to cope with fluid maldistribution in separators/reactors for the integrated offshore hydrocarbon processing ( e . g ., floating-production-storage-offloading). , The main driver for the latter technology for instance takes advantage of seaborne transport of natural gas/crude oil and their upgrade en route into a range of fuels/petrochemicals using onboard scrubbers/reactors akin to their onshore refinery siblings. , This process concept is promising as it simplifies the product-to-market distribution in addition to ensure profitability into tapping smaller/remoter offshore fields saving the high costs of sea platforms and pipeline connections to onshore refineries …”

A marinization test rig comprising a hexapod/column/wire-mesh-sensor assemblage was used to emulate the liquid drainage onboard floating packed columns. Single and compounded rotations and translations of tilting (roll, roll + pitch) and non-tilting (yaw, sway, heave, sway + heave) types were implemented on the robot to allow measurements of time-resolved local free-draining liquid saturation and drainage rates for various oscillation amplitudes and periods of the moving packed bed. The liquid drainage evolution highlighted, irrespective of the hexapod configuration, a succession of rapid and slow discharge stages disjointed by an abrupt short-lived transition with zero net liquid drainage rates. The gravity characteristic time, by dwarfing the periods of the sine wave excitations, singled out the oscillating gravitational force as the main factor behind the change of the liquid drainage response, whereas the influence of the moving-frame fictitious acceleration was minor. Drainage under rotational oscillations mainly depended on the instantaneous bed inclinations, thereby impacting the instantaneous partition of the liquid between the column lowermost and uppermost zones. The prominent role of gravity at the expense of robot acceleration was also corroborated by the invariance of the liquid drainage profiles with respect to non-tilting equal-period oscillations, which barely deviated from the drainage profile of a static vertical column.
