Mooring Integrity

MOORING INTEGRITY USER GROUP

#UserGroups #Offshore
The Mooring Integrity User Group is a forum of exchange between operators, Class Societies and engineers to share experience and build up industry knowledge on mooring systems.

EOLINK

#OtherCollaborativeProjects #MRE
Bureau Veritas has partnered with Eolink on the component certification of their pre-commercial 5MW floating offshore wind turbines.

MOORLIFE

#JIP #Offshore
The objective is to reduce uncertainties in mooring chain fatigue life predictions by improving corrosion state quantification with accessible assessment tools, enhancing understanding of variable amplitude loading effects on damage accumulation, and developing integrated finite element models that incorporate local and residual stresses for better fatigue crack initiation and growth analysis.

LIFELINE  

#UserGroups #Offshore
The LifeLine Group follows on from a JIP to support the practical application of the outcome technology in the field. An onboard software can provide real-time feedback on the health of FPSO mooring lines and thus help extend their use. In phase 2 of the LifeLine Group project an Approval In Principle (AIP) will be obtained from BV. Also the need of a LifeLine system for floating wind turbines will be investigated.

DONUT 

#MooringIntegrity #Offshore
Donut is a multiple-phase Joint Industry Project (JIP) aiming at enabling remote assessment of mooring systems underwater.

 

Reliable assessment of the integrity of mooring lines is of critical importance for the operation of floating energy production units, such as Floating Offshore Wind Turbines (FOWT) and Floating Production Storage and Offloading (FPSO). Damage in the mooring lines can create unacceptable risks to the entire asset and the subsea environment. The feasibility of detection, localization, and characterization of corrosion and fatigue damage in subsea chain links using active and passive techniques are investigated in this project, with the aim of creating/updating a digital twin of the mooring system.

OC7

OC7 is a research project managed by NREL. It is a new iteration following the Offshore Code Comparison Collaboration, Continued, with Correlation, and unCertainty (OC6) project. It aims to improve the modelling of hydrodynamic viscous loads for floating offshore wind platforms to validate the accuracy of load predictions (especially aerodynamic loads) in a wind farm, with a specific focus on the influence of the floater flexibility.

MONIMOOR

#JIP #Offshore
Monimoor is a Joint Industry Project (JIP) lead by MARIN. Its main objective is to develop a monitoring system able to follow the accumulation of fatigue in the mooring system based on monitoring data and to apply this on several types of units, both O&G and MRE.

ARIANE

#Software #Offshore
ARIANE is our in-house software for mooring simulations. It is especially focused on offshore oil & gas industry requirements, and has been developed for greater efficiency using simplified assumptions such as catenary lines models. Offloading operations, including side-by-side configurations, can also be simulated.
