Mooring System Transport and Installation Logistics for a Floating Offshore Wind Farm in Lannion, France

Abstract

This study addresses the planning procedures for the installation of the mooring systems that support the floating offshore wind turbines in a wind farm. It considers the logistics of the installation process and discusses the important role of the weather windows in the planning of those operations at a preliminary stage of the project. The case study is based on a wind farm array of 47 Telwind floating wind turbine platforms, to be located in Lannion (France), with a potential of 470 MW. The study includes the transport and logistics requirements of different mooring components, such as chains, connectors and drag anchors; the description of the installation operations considering the typology of vessels that are necessary in these manoeuvres; as well as the planning and costs associated with the transport and installation. Given the diversity of elements and operations involved in the installation procedure, it is demonstrated that the research results of duration and costs of this type of operations are only possible to obtain using a simulation tool.

Techno-economic evaluation and resource assessment of hydrogen production through offshore wind farms: A European perspective

“…CAPEX EC,HV DC = RC EC,HV DC • P EC,HV DC • L EC (25) where RC EC,HV DC is the linear cost of the cable, estimated at 1.35 €/W/km [16,67], P EC,HV DC is the rated power of the export cable (MW) and L EC is the length of the export cable.…”

“…Depending on the level of detail, installation techniques [17] and costs are often considered [18][19][20], but also operation and maintenance [20][21][22] and decommissioning [20,23,24]. These modelings have sometimes been subject to specific adaptation, for example for floating structures in deep waters [25][26][27][28]. These cost-modeling approaches have been integrated into many resource assessment studies [29][30][31].…”

Fuzzy Multi-Criteria Decision for Geoinformation System-Based Offshore Wind Farm Positioning in Croatia

“…According to Chen and Su [3], the OWF scientific field is rapidly expanding, and it was stated that the growth in paper publishing has been significant in the last decade. Moreover, a lot of papers deal with OWFs and their technical, technological [4][5][6][7][8][9][10][11][12][13] and economic [14][15][16][17][18][19] aspects. Some of them analyze the wind-wave combined energy [20][21][22] and the concept of Smart OWF and 5G technology [23].…”

Dynamic Response of DP Offshore Platform-Riser Multi-Body System Based on UKF-PID Control

“…Large maritime constructions like floating offshore platforms and special engineering vessels that float in the water might typically have their location and spatial attitude determined by empirical calculations based on heading angles, velocity, and ocean currents [1][2][3][4]. In fact, the changes in a ship's position that can be roughly calculated by empirical formulas are not timely and not accurate enough, and for some construction projects that require high accuracy and fast feedback speed, they are far from meeting their technical requirements [5][6][7].…”
