River Crossing

(Jakarta, July 14, 2009)

Pada pekerjaan pipeline, khususnya onshore pipeline, sangat sering dan tidak bisa dihindari beberapa jenis crossing yang terjadi pada pipeline project.

Beberapa crossing yang sering tidak bisa dihindari adalah:

1. Road Crossing (Crossing Jalan),
2. River Crossing (Crossing Sungai)

Ada pula beberapa crossing yang tidak selalu ada dipekerjaan pipeline, seperti:

1. Rail Crossing

Yang ingin di bahas sekarang adalah masalah River Crossing. Sungai-sungai yang dilewati oleh pipeline ada yang begitu lebar dan adapula berupa sungai kecil atau malah hanya melewati selokan. Sehingga pada pekerjaan engineering ada yang harus dianlisa pakai pendekatan engineering adapula yang sudah cukup dengan typical crossing seperti project2 yang sudah pernah dikerjakan, biasanya setiap client/Oil Company yang besar sudah mempunyai standard masing2 atau mengacu pada Standard International yang sudah ada.

Kenapa perlu ada analisa pada River Crossing apabila melewati sungai yang cukup lebar?

Jalur pipa (pipeline) yang akan menyebrang sungai akan membutuhkan perlakuan khusus pada pekerjaan ini. Apabila pipeline hanya ditarik dan diseberangkan ke sisi sebalah sungai yang lain, pipa akan mengapung di air apabila daya angkat pipa lebih besar, pipeline-pun tidak mengikuti natural curvature –nya karena kita tidak memperhitungkan dan mendesainnya seperti itu, tentu ini tidak diinginkan, apalagi jika sungai ini aktif dan banyak kegiatan diperlintasannya.

Beberapa data yang harus dipersiapkan u/ mendesain River Crossing:

1. Contour /profile sungai,
2. Data tanah (berat jenis, jenis tanah dst),
3. Data Arus Sungai (kecepatan arus),
4. Data Pipa (mechanical data),
5. Data Coating,
6. Data Process
7. etc

Tahapan untuk mendesain, pertama kita harus mengetahui natural curvature dari pipa itu sendiri. Natural curvature bisa menggunakan dua alternative coating (pemberat/ additional weight). Apabila menggunakan additional weight dengan system perberian dibeberapa titik, maka calculation design berdasarkan natural curvature dari pipa itu sendiri (bare pipe).

Jika additional weight menggunakan coating disepanjang pipa, maka perhitungan berdasarkan natural curvature dengan pipa ber coating.

1. Bare pipe Radius Curvature

Formula untuk minimum radius curvature dengan pipa polos (bare pipe) adalah:

Dimana:

R = Radius Curvature

E = Young Modulus

D = Outside Diameter

SMYS = Specified Maximum Yield Strength

DF = Design Factor

1) Offshore Pipeline Design, Analysis and Method, A.H Mousselli

2. Coating Pipe Radius Curvature

Apabila pipa yang digunakan adalah pipa bercoating, maka rumus yang digunakan adalah:

1. Concrete Yield Strength (40% Concrete Compression Strength)

Dimana:

R1 = Radius Curvature

Ec = Young Modulus of Concrete

D = Outside Diameter

Yield c = 0.4 * fc

Fc = Concrete Compression Strength

DF = Design Factor

1. Concrete Tensile Strength (10% lesser than yield strength)

Dimana:

R1 = Radius Curvature

Ec = Young Modulus of Concrete

D = Outside Diameter

Tensile = Yield – (o.1*Yield)

DF = Design Factor

R=max(R1,R2) à mana yang terbesar ini yang menjadi acuan design.

Untuk design natural bending curvature bare pipe bisa juga dengan menggunakan API RP 1117.

Untuk perhitungan besaran concrete coating (additional weight) bisa mengikuti tahap2 seperti perhitungan di pushpull calculation.

Tentu perlu juga kita tambahkan perhitungan effect dari upheaval buckling yang mungkin terjadi pada saat pipeline sudah berada di bawah dasar sungai.

Semoga bermanfaat. Selamat mengambil hikmahnya.. kalau ada saran dan masukkan tolong disampaikan untuk koreksi dan perbaikan..

Salam persahatan

Kangen juga mau nulis masalah Pipeline, sudah lama dan sedang rame2nya koalisi partai yang nyambung dan putus.. memang kalau sesuatu yang ngantung bikin orang lain tidak enak dan nyaman. Laa.. kok arahnya ke politik.

Kurang lebih satu bulan yang lalu, ada pekerjaan di Handil, Balikpapan yang menggunakan methode push pull untuk daerah rawa (swampy) kurang lebih 2 km. Daerah rawa ini cukup unik, pada saat musim hujan terlihat seperti danau besar dan kebalikkannya pada saat musim kemarau kering dan bersemak, tapi daya dukung tanah sangat rendah, dinaikin orang aja akan jeblosss.. apalagi membawa alat berat untuk mengangkut pipa sampai ke seberang.

Dapat kita bayangkan pipa berdiameter 24”, ketebalan 1” ditambah coating dan concrete weight, sehingga total berat antara 8.5 – 9 ton akan diseberangkan di daerah seperti ini. Bisa bikin pusing para site manager dan field engineer bila kurang persiapan dan tidak mempunyai methode untuk mengatasi masalah ini.

Push pull di swampy area method yang dipakai hampir sama dengan shore pull di offshore method. Kalau shore pull ditambah dengan laying analysis-nya, sedangkan pada push pull method murni tarik dan tekan sampai ke seberang.

Dengan tenaga ahli dan kecerdasan teman2 dilapangan dan perhitungan yang matang maka semua proses ini bisa dilaksanakan dengan lancar tanpa masalah, walaupun sempat terjadi ketegangan karena pipa belum mengapung juga.

Pipa disaat masih dalam kekakuan penuh, akan mengikuti kemiringan yang disediakan sampai batas tekuknya baru akan lurus dan bisa naik ke atas. Sebenarnya menurut saya pribadi, kita tidak perlu sampai batas tekuk pipa, kita bisa melakukan penambahan daya angkat pipa terhadap air di depan pipeline yang diseberangkan. Karena kalau kita menunggu tekuk pipa membutuhkan kedalaman yang lebih dan pekerjaan yang membuat kita khawatir juga.. J resiko pipa kandas di dasar swampy adalah resiko terbesar, karena akan butuh teknik tersendiri untuk mengangkat pipa tersebut.

Analisa push pull di swampy area sudah merupakan perpaduan antara field engineering dan engineering consultant, posisi saya di engineering consultant sempat diingatkan kalau ini bagian pekerjaan site. Karena pernah bergabung dan sering bantu di Contractor menjadikan saya ingat, paling tidak methode analisanya engineering consultant membantu, sedangkan real di lapangan harus dicek dan disesuaikan.

Pada pelaksanaan ini kita menggunakan drum yang ada dipasaran, sehingga mudah mendapatkan di lokasi pekerjaan.

Steps analysis of Puss pulls in swampy area.

1. Buoyancy of pipe
2. Weight of pipe with coating – water absorb
3. Total Weight = point 2 – point 1
   
4. Buoyancy of tank (drum) à disesuaikan dengan keinginan dilapangakan, apakah kita ingin drum nonggol ¼, 2/3 atau penuh.

1. Specific Gravity

Pipa dinyatakan Stabil berdasarkan [DNV RP E305 Sec.3.2.2] adalah

Specific Gravity > 1.1

Apabila SG sesuai seperti yang disyaratkan maka tidak perlu melakukkan tambahan pemberat untuk pipa atau additional weight. Apabila perlu dibuat design pemberat pipa dari concrete weight seperti specification client atau dapat diambil dari design yang sudah ada sampai pipa dinyatakan stabil.

Langkah perhitungan ini hanya untuk membantu analisa dilapangkan, sedangkan pelaksanaan dilapangan harus dilakukan perhitungan ulang. Banyak data2 dilapangkan kadang berbeda dengan data analisa di meja.

Perlu juga diperhitungkan wire rope yang mampu menarik pipa2 tersebut sampai keseberang. Kalau dihitung pipa di udara tentunya akan ketemu wire rope yang besar, karena pipa akan meluncur di air maka ini akan tereduksi significant. Pondasi tempat peluncuran pipa, design seefektip mungkin, atau kita bisa menggunakan skid yang dibuat sedemikian mungkin sehingga mampu menahan dan melancarkan peluncuran pipa selama pelaksanaan. Pelaksanaan juga membutuhkan winch sebagai penarik pipa sampai sepanjang 2 km ini, kalau kita menghitung satu pipa di udara, minimal 3 pipa sehingga total berat adalah 3 * 9 ton = 27 ton, secara kasat mata kita menggunakan winch dengan kapasitas 30 ton. (wow.. gede sekali!!). Tetapi dengan menggunakan winch yang lebih kecil 15 ton, dengan dibikin kemiringan pada skid peluncur ditambah ballast roda-roda, ditarik dengan swampy backhoe berkapasitas 7 ton, pelaksanaan ini berjalan sampai selesai dan Alhamdulillah lancar.

Itu dulu yang bisa saya sharing kan, semoga bermanfaat untuk teman-teman semua, yang butuh bantuan atau bertanya silahkan kontak via imel dan blog ini.

Tiada yang lebih indah selain berbagi, semoga amal dan ibadah kita menjadi berkah buat kita semua dan keluarga. Amin..
