Steel monopiles, jackets requiring four steel pinpiles, and gravity-based foundations were applied in offshore wind farms in the Belgian part of the North Sea. This paper compares the underwater noise generated during the piling activities of steel monopiles at the Belwind wind farm (Blighbank) with that of jacket pinpiles at the C-Power project (Thorntonbank). Underwater noise was measured at ...

FAST, developed by the National Renewable Energy Laboratory, is a computer-aided engineering tool for aero-hydro-servo-elastic analysis of land-based and offshore wind turbines. This paper discusses the development of a new module (SubDyn), which when integrated to FAST, will enable loads simulations of offshore wind turbines with fixed-bottom, multimember support structures. The main theory an...

Background: Offshore oil and gas platforms generally have a lifetime of 30 to 40 years, and platform decommissioning is a major issue because many of the existing offshore oil and gas platforms are reaching the end of their service life. There are many possible options for decommissioning offshore oil and gas platforms, and each decommissioning option can be implemented using different methods ...

As an important contribution to the fulfilment of renewable energy targets, offshore wind sector in Europe has grown significantly over past decade (WindEurope 2021). Jacket structures are becoming more widely used as substructures for turbines accommodate expansion towards greater water depth and provide a stable basis megastructures with hub heights than 200 m. However, there have been few st...

Offshore platforms are known to act as artificial reefs, though there is on-going debate on whether this effect is beneficial or harmful for the life in the surrounding marine environment. Knowing what species exist on and around the offshore platforms and what environmental variables influence this species assemblage is crucial for a better understanding of the impact of offshore platforms on ...

In order to understand the economic feasibility of an offshore wind farm, this paper analyzed differences in LCOE (levelized cost energy) according support type and construction method substructure terms sensitivity analysis was conducted main components LCOE. As for site be studied, Southwest Offshore Wind Farm selected, capital expenditures were calculated size farm installation unit. a resul...

explosion and fire on an offshore rig can lead to its minor or complete damage and sinking which means the loss of life or environmental pollution. hence the use of techniques such as blast wall is crucial to reduce the detrimental effects. these blast walls are designed for explosion wave of length between 0.1 to 1 of load mainly to protect the personnel and critical sections. in this research...
