... ABSTRACT During the installation process, drag anchors may impact or hook with subsea pipelines buried in seabed, resulting in damage to the pipelines. The inshore subsea pipeline is often protected by a rockfill protection layer, so the pull-out trajectory of drag anchors in the rockfill...

... floating wind farms. In this study, a novel self-installation method for installing a new concept triple-column Spar floating wind turbine system is proposed, which not only accelerates the installation process, but also drastically reduces the associated cost. By employing the self-installation method...

... ABSTRACT The installation phase is a critical stage during the lifecycle of an offshore wind turbine. The technology development of bottom-fixed offshore wind turbines is more mature compared to that floating wind turbines. This paper focuses on the installation process of an offshore monopile...

..., China endeavors to achieve scheduling and rescheduling. However, it is not an easy task to schedule carbon neutrality by 2060 (Mallapaty 2020). Even though wind energy the offshore installation process, since it is heavily influenced by the is the fifth-largest energy source worldwide, its share...

... In this paper, an agent-based discrete event simulation model is proposed. This research considers the decommissioning process as a reverse process of the installation process. As empirical values for the decommissioning process are not available yet, the processing times and operation restrictions are derived...

... Abstract Marine riser is a key equipment connecting subsea wellhead and sea-surface platform (ship). In Subsea Production Tree (SPT) complex installation process, the marine riser hanging to floating drilling platform (ship) on free hanging state, waiting to be moved from the sea-surface...

... a challenging task. Due to the current practice of decentralized information acquisition by the supply chain partners, we investigate the impact of sharing information on the installation process of offshore wind farms by means of simulation model. Therefore relevant information items will be identified...

... With the accidents of offshore structures occurring frequently, the risk assessment of transportation, installation and operation process is becoming more and more important. In this paper, the risk assessment of transportation and installation process of jacket is presented. Firstly, the main...

... unconditionally during operation. Unlike Spars, DTP can be towed to site with the topsides integrated at quayside. Unlike TLPs, DTP can be used in ultra-deep water. This paper includes a description of the unique feature, summaries of global performance, and installation process of DTP. Through the analysis, DTP...

... by asking and answering the question; "Does the reeled installation method introduce a greater risk of failure in-service than other installation processes?" The argument is constructed by assessing each limit state, meaning the fundamental ways that a pipeline can fail (burst, collapse, fracture...

... and end of the pipe-laying process. The advantages of a spool piece are among others its flexibility and the relatively simple process of reversing the installation process if necessary. This is especially important in deep waters where the cost of accessibility is high. The spool piece is fabricated...

... wave conditions. The installation of caissons for a breakwater is sometimes interrupted or suspended by wave conditions. During this installation process, winches are hand-operated by several operators under sometimes dangerous conditions due to the operator's proximity to the winches and wires...
