MOORING COMPONENT ASSESSMENT PHASE II

MOORING COMPONENT ASSESSMENT PHASE II. MCA II JIP

Main Objective:

To extend the Engineering Critical Assessment (ECA) methodologies for applications in mooring chain components.

  • To develop additional fracture toughness data for 34CrMoNi steel through controlled sampling/testing from spare components to populate the JIP database and Kmat estimation procedure.
  • To perform further residual stress evaluation (experimental and numerical) to clarify the scatter and variability identified in Phase I and develop fracture mechanics treatment procedures.
  • To develop quantitative flash weld acceptance criteria and extend the ECA procedure developed in Phase I for chain links.
  • To perform large scale mooring component fracture tests for validating the developed ECA procedure.
  • To develop a risk-based matrix for interpretation of ECA results for both mooring connectors and chain links.

Main Participants:

Total, BV, PD Technologies, Exxon, LeBeon Manufacturing, SBM, Chevron, Asian Star and Vicinay Marine Innovación.

Execution Period:

2014-2018.
