1.0 Subsea Pipeline Stability Standards Review
1.1 PETRONAS technical standards - PTS 31.40.00.10
The PTS offer the
traditional static analysis.
1.2 British Standard - BS8010-2:2004
Generally, BS8010
follow the DNV RP E305 & DNV OS F101
1.3 ASME\ANSI B31.8
ASME B31.8 recommends
the traditional static analysis.
1.4 API recommended practice 1111, 4 Edition, Dec-2009
API use AGA research
(PR-178-516 & PR-178-717) for on-bottom stability analysis. The AGA research
defines 3 levels for stability analysis.
Level1: static
analysis with single airy wave
Level 2: static
analysis with wave spectrum and embedment
Level 3: dynamic
analysis with random wave kinematics
Level 3 is similar to
DNV code. AGA use Lstab software for stability calculations.
1.5 TOTAL General Specification, Submarine pipeline system, GS PLR 100
GS PLR 100 suggests
DNV or equivalent codes.
1.6 DNV
DNV published DNV RP
E305 in 1988 and considered pipeline stability for static and dynamic and
generalized methods. DNV developed this standard in DNV RP F109. DNV commonly
used for stability of submarine pipeline
1.7 Conclusion
DNV RP F109 is
considered as a best code for stability calculation and this report is based on
it.
