... Abstract Much of the hydrocarbon production in Brazil originates from offshore operations in pre-salt fields. The pre-salt fields are located more than 300 km from the coast, in water depths of around 2,000 meters, with reservoirs 7,000 meters from the sea surface. Operating in such conditions...

... Abstract Maintenance and continuous monitoring of offshore structures and ships are essential in ensuring the integrity and safety of these high-value assets. Manual inspection methods are labor intensive, time-consuming, and often dangerous. Unmanned Aerial Vehicles (UAVs) also called drones...

... Abstract As Brazil’s offshore fields age, the need for decommissioning subsea structures is intensifying. While the importance of decommissioning is well understood, the current literature lacks a detailed stochastic approach for the decommissioning of subsea pipelines. This paper fills the gap...

... Abstract Subsea mudmats are employed extensively as a shallow foundation on soft clay to support the seabed structures for offshore oil and gas developments. Compared with a conventional fixed mat, an emerging concept of the tolerably mobile mudmat, which is to allow foundations sliding...

... Abstract The current design practice for offshore monopiles applies widely accepted simplifications of complex irregular loading scenarios. Highly cyclic loads from varying directions offshore are simplified by means of classification methods. This procedure involves reordering individual...

... of aquaculture facilities under different sea conditions is discussed, and the effect of avoiding wind and waves after diving under extreme sea conditions is analyzed. It proves that this facility satisfies the requirements of offshore kelp cultivation, thus providing an essential reference for seaweed...

... Abstract The integration of energy storage systems (ESS) on a large-scale is becoming essential to mitigate intermittency issues in power supply from offshore wind farms. This paper deals with an offshore Hydro-Pneumatic Energy Storage (HPES) system comprising of a subsea accumulator pre...

... Abstract Submarine landslides can entail a substantial hazard for offshore infrastructure as they are capable of triggering tsunamis and may develop into highly mobile turbidity currents capable of breaking seabed cables. Despite considerable research activity, the trigger mechanisms...

... Abstract Cost optimization of asset management is a central issue in the offshore Oil and Gas strategy, and risk-based approaches, such as Risk Based Inspection (RBI), have been more and more employed to assist the segment in the concretization of that goal. The inspection procedure aims...

... Abstract The objective of this project was to develop guidance for a Type Approval for FRP handrails in fire integrity applications offshore. BP, MODEC, PETROBRAS, ABS and NOV Fiber Glass Systems came together to form an FRP Industry Group which developed a Fire Integrity Matrix intended...

... Abstract For safe and cost-efficient operations of new and existing offshore Arctic pipelines, monitoring of pipeline structural integrity is imperative. A well-founded pipeline integrity management program can optimize production output, extend the life of the pipeline, and serve as a tool...

... Abstract Pipe bends are peculiar structures. Although the mechanisms that determine their behaviour are not that different from those of initially straight pipe, their relative contribution can be. This is amplified by shorter bend radii and thinner walls. Typical bends used in an offshore...

... Abstract Offshore wind turbines are poised to become a vital part of the global energy landscape — particularly the floating types which give access to a much greater wind power resource. The design possibilities for floating turbines are so different from onshore and offshore fixed-bottom...

... Abstract As a rapidly developing technology, the expanded capability of Additive Manufacturing (AM) allows implementation into the marine and offshore industries. Qualification of metal AM part may need detailed test plans and test results in order to meet the design requirements with a certain...

... Abstract Offshore pipelines in an Arctic or ice-covered environment face unique challenges different from traditional subsea pipeline design. In 2018, Intecsea as lead consultancy delivered a report to the US Bureau of Safety and Environmental Enforcement (BSEE) Alaska Region which provided...

... Abstract Drilling activities are risky and costly, especially when performed offshore. Careful monitoring and real time data analysis are required for safe and efficient operations with minimized down-time. Drilling operations, being fast-paced and not visible, often lead to transient...

... Characteristics of the drifting ice cover and the scenarios of the ice loads on offshore structures are the major parameters defining durability and reliability of the ice-resistant platforms on the Sakhalin offshore. The study is devoted to the problems of probabilistic and numerical modeling...
