Designdevelopmentof OffshoreMooringChains
Fatigue Life Test
A Mooring Chain has to endure at least 25 years
in tides, winds and the corrosive harsh
offshore environment. For this reason, the
fatigue life of a chain is the utmost
importance.We installed 6300kN Fatigue Tester to
test full- scale chain andaccessoriesforeach
grade (R5, R4S, R4, R3S R3) at air and salt
water conditions, and also make efforts to
develop long-term Fatigue Life Chain.
Finite Element Analysis We satisfy customers
needs by determining stress
distribution that affects the link in the Mooring
system through FEA(Finite Element Analysis)
method when developing chain or changing design.

CTOD Test (Crack Tip Opening Displacement Test)
Stress Corrosion Crack
Heat Treatment
For higher strength quality chains (Grade R4S
R5), we can reduce retained Austenite Structure
in the chain through Double Heat
Treatment(Double quenching tempering) and can
obtain Fine Grain size as well as securing the
homogeneity of microstructure. In addition, we
are trying to increase impact strength by
improving the ductility of welding area of chain
and endeavorto makelongerFatigueLifeof theChain.
Mooring Chains used in a harsh offshore
environment are vulnerable to fracture due to
Stress Corrosion Crack under tensile stress and
corrosion conditions. DaiHan Anchor Chain Mfg.
Co., Ltd. carries out Stress Corrosion Cracking
Test for Mooring Chain in collaboration with
Korea Atomic EnergyResearchInstituteundervariousc
onditionsinorder to manufacture and design the
best quality chains to prevent early cracking.
Mooring Chain used for the safe installation of
offshore structures require Mechanical
Properties Test(Tensile Strength and Impact
value) as well as CTOD Test for soundness
evaluation for the chains. Team up with Doosan
Heavy Industries Construction,we carry out
full scale CTOD tests for mooring chains of each
gradeandtemperaturewithfullscalespecimen.
NDT System
To make up for the disadvantages of conventional
UT(UltrasonicTest)andtodetectembededdefectsstably
reliably, Phased Array type Automatic UT system
with the vertical inspection lines has been
introduced installed for better inspection
efficiencyand accuracy.

• Advantage
• Secure accuracy and reliability through automated
  test instead of manual test by inspector
• Reduce inspection time by scanning from various
  angles
• Examine parallel embeded any other defects of
  Flash ButtWeldareabyscanningfromvariousangles
• Easy defect analysis and reading through
  real-time image realization(A, B, C, D S)
• Secureidentificationandtraceabilitybyrecordingand
  saving test data for each link
