ABSTRAK

Tugas akhir ini membahas salah satu kasus buckling dalam kaitannya untuk menghindari timbulnya upheaval buckling pada buried offshore pipeline yang sedang beroperasi. Bahasan dalam tugas akhir ini mencakup analisa pengaruh temperatur kedalaman tanah dan tipe tanah terhadap terjadinya upheaval buckling dalam tugas akhir ini dilakukan analisa dalam beberapa kondisi yaitu pada temperatur 350 C 600 C dan 1000 C kedalaman penanaman pipa 1.5 meter 2 meter dan 3 meter serta tipe tanah sand dan clay. Selain itu tugas akhir ini juga membahas tentang beban dan tegangan yang terjadi pada pipa saat terjadi upheaval buckling. Analisa yang dilakukan didasarkan pada kriteria yang ditetapkan oleh DNV OS F101 ASME 31.1 ASME 31.4 dan ASME 31.8 sedangkan untuk memodelkan pipa menggunakan software CAESAR 4.2. Dari hasil analisa pengaruh kenaikan temperatur pada saat operasi terhadap upheaval buckling cukup signifikan dimana semakin tinggi temperatur operasi maka semakin besar pula peluang terjadinya upheaval buckling. Sedangkan untuk pengaruh tipe tanah dan kedalaman penanaman pipa dimana semakin tinggi nilai cohesive tanah dan semakin dalam penanaman pipa maka peluang upheaval buckling akan lebih kecil. Berdasarkan perhitungan diperoleh beban dan tegangan kritis pada pipa yang menyebabkan buckling sebesar 8.7 kN dan 361.2 kPa.


ABSTRACT

This final project discusses a case of buckling in relation to avoid the occurence of upheaval buckling in operating buried offshore pipeline. The discussion in this final project includes the analysis of the effect of temperature burial depth and soil type on the occurence of upheaval buckling. In this final project analysis is conducted in several conditions namely at the temperature of 35 C 60 C 100 C pipe burial depth of 1.5 meters 2 meters and 3 meters as well as the soil types of sand and clay. In addition this final project also discusses the load and stress that occurs in the pipe during the upheaval buckling. Analysis is performed based on the criteria established by DNV OS F101 ASME 31.1 ASME 31.4 and ASME 31.8 while the CAESAR 4.2 software is used for pipeline modeling. The result of the analysis shown that the effect of temperature rise on upheaval buckling is significant which is indicated by the higher the operating temperature the greater the possibility of upheaval buckling. Meanwhile for the influence of soil type and pipe burial depth it is observed that the higher the soil cohesive value and the deeper the burial depth the possibility of upheaval buckling is rather small. Based on the computations the critical load and stress which causes pipe buckling are of 8.7 kN and 361.2 kPa.
