B/525/12 - Design of offshore structures

Sector: Construction

Categories: Technical aspects | Processing equipment | Structures. Metal | Fire-resistance. Building materials and elements | Exploratory, drilling and extraction equipment | Bridge construction | Earthworks. Excavations. Foundation construction. Underground works | Containers. General purpose | Building elements | Building structures

Overview: Standardization in the field of offshore structures used in the oil and gas and lower carbon energy industries, which includes as it pertains to the substructure (for generation and substations) for: oil and gas; offshore structures for use of lower carbon/renewable energy production (e.g., wind, wave); offshore CO2, H2, and NH3 storage; platform life extension, re-use in new locations and/or re-purposed; and installation and removal.
