| Description |
During the last 10 years, the offshore industry has
shown an increasing interest in suction anchors so there is a need to
calibrate safety factors for suction anchors. Suction anchors continued to
be first choice, but drag-in plate anchors emerged as a potential
alternative 5 years ago, especially by Petrobras in Brazil. This JIP
objectives were:
-
Structural reliability analysis for calibration of
a design code for design of suction anchors,
-
Develop design code for suction anchors and
describe a model for use in the reliability analysis,
-
Use the reliability analysis for calibration of
the design code for suction anchors,
-
Identify key issues for design of suction anchors,
-
Document code in a DNV Recommended
Practice(RP-E303), and
-
Compare results for suction anchors with the
results for plate anchors (updated DNV RP-E302).
