| Summary: | ABSTRACT: <br />
<br />
<br />
Pipeline lay on seabed can be influence by complex Hidrodynamic forces. Seabed is the foundation of subsea pipeline and the Hidrodynamic forces can make seabed transformation and change the stability of pipeline. It can make pipeline failure. Seabed transformation can be scouring or deposition. Seabed transformation is the principal and the first pipeline analysis, so transport sediment pipeline analysis is very important to be understanding and learning. <br />
<br />
<br />
Seabed transformation is not only cause by scouring around pipeline due to current and wave, transport sediment can make seabed transformation too. <br />
<br />
<br />
In this research, pipeline route in LNG Tangguh project, West Irian, Indonesia from Vorwata A Platform to LNG Plant will be analyzed. Pipeline dimension will be used is 24” diameter, 0.688” thickness and 132 bar design pressure. <br />
<br />
<br />
The result of the research give in Bintuni bay area, specially Vorwata Block have high speed flow velocity. It make this area have some sediment deposition and have large scoured area. For this complex case, it will need future analysis for detailed, free span analysis by way of example. |
