New Joint Industry Proposals

SheathFlex JIP
Guideline for qualification of pressure and outer sheath materials in unbonded flexible pipe
The proposed JIP will gather all the manufacturers and operators to align on: 
– the methodology to establish the list of qualifications tests to be performed
– the minimum qualification tests needed per type of polymer/material family and applications
– the complementary qualification tests
– the test procedure principles together with their requirements for each qualifications tests
– Issue a guideline defining the requirements to qualify internal pressure sheath and external sheath  materials for unbonded flexible pipe considering pipe body and end-fitting area.

HoliMoor JIP
An integrated framework for corrosion condition monitoring and fatigue capacity assessment of mooring chains.
The objective is to better account for the combined effect of fatigue and corrosion on the lifetime assessment of offshore steel mooring chains, with use of an integrated experimental, modeling and database framework.  The potential of the framework and methodology will be also demonstrated through selected cases studies.

Riser retrofit sensor network for lifetime extension JIP
Retrofit subsea sensor nodes for continuous monitoring using battery less and wireless technology. 
This JIP has the objective to reduce risk of failure for critical infrastructure such as risers and mooring chains by collecting continuous sensor information from retrofitted nodes.

Mooring Systems Wear
The objective of the MSW JIP is to improve wear estimate knowledge for the specific conditions experienced by mooring systems inter-component wear, and to define a mooring systems inter-component wear estimation guideline.
Contact: Pedro Barros and Simon Dimopoulos

The aim is to develop knowledge and procedures to enable the design and use of nylon mooring systems for floating wind turbines with high durability in the ocean environment.

Dynamic Response of Offshore Pipelines and cables on the Seabed, Phase III
The objective of Phase III of the DROPS JIP is to further enhance the SIMLA software tool to correctly simulate the physical behaviour of subsea pipelines and cables in the operational phase by including functionality to perform 3D non-linear time domain VIV (Vortex-Induced Vibrations) analysis of free spans.

Lazy Wave Riser JIP, Phase III

The objective of LWR JIP Phase III is to further enhance the VIVANA-TD software tool to predict marine riser and dynamic power cable responses under simultaneously acting wave and VIV (Vortex-Induced Vibrations) loads.

Multi-fidelity and Probabilistic Life Enhancement for Slender Marine Structures
The objective is to model and reduce the uncertainties in lifetime prediction of marine risers and dynamic power cables at desired risk levels using probabilistic and multi-fidelity modelling based on measurement data.

Cold Water Pipe JIP (CWP JIP)
Design and Model Testing of Large Diameter Deep Cold Seawater Intake Pipes for FPSOs, FLNGs and OTEC. 
The objective of the CWP JIP is demonstrate to the industry that large diameter cold water intake pipes can be successfully installed and will provide reliable in operation for decades of use.  This includes addressing the crucial connection joint at the top of the CWP to the hull.  Model testing will be a key part of the demonstration process.

The proposed JIP will optimize:
– the number of calculations by identifying useless and non-dimensioning DLC.
– Determine model simplifications that can be implemented according to the design objective.

Preferential Weld Corrosion (PWC) is observed more frequently on permanent mooring chains, and in some cases has been determined to be the cause of failure of some mooring lines. So far, the occurrence of PWC does not seem to be correlated to either chain grade, water depth, geographic location, or manufacturer. This JIP will investigate the following:

  • Prevalence of PWC within the permanent mooring industry
  • Characterization of PWC features, and identify relevant correlations
  • Study the driving factors that cause PWC, through modeling and field tests.
  • Provide guidance tools on the risk of PWC related to the integrity of the mooring system.

Initiative: MARIN and NREL have initiated the SCALEWIND JIP to develop a widely accepted floating wind turbine design assessment methodology that leads to efficient design convergence and reduced operational uncertainties for large scale floating wind.
