MOORING & DYNAMIC POSITIONING
For offshore floating units, a reliable station-keeping system is one of the most important facilities to guarantee safe operation for oil and gas exploration activities. Spread mooring systems are designed to keep structures like semi-submersibles, FPSOs and offshore wind turbines floating, despite combined forces such as wind, waves and current. Under the same conditions, Dynamic Positioning devices can enable the dynamic station-keeping of ships and offshore units.
Comprehensive and accurate assessment of station-keeping systems must be performed to ensure adequate structural strength in harsh weather. Tough conditions can lead, for example, to chain connectors clashing with riser bend stiffeners. The material of mooring components can be steel chain, steel wire ropes or synthetic fiber ropes, which must be designed to withstand extreme weather conditions and fatigue damage for their entire life.
Over the past two decades, Bureau Veritas Solutions Marine & Offshore has accumulated extensive experience and gained unique insights into mooring systems and DP systems from design to operation.
We provide technical consultancy services related to the analysis of station-keeping systems including static, dynamic analysis, strength checking, fatigue analysis, heading analysis for turret, spread mooring and any kind of temporary mooring systems. These services are performed using advanced numerical tools (i.e., Hydrostar, Ariane) developed by Bureau Veritas, and external software such as Orcaflex and Deepline.
