This calculation sheet for design of CRUDE PALM OIL POND TANK on

Indurtrial Estate at Lubuk Gaung - Dumai - Indonesia.

The first stap design capacity of tank are 50.000 m3 and Total design capacity

storage of tank will be 300.000 m3 Crude Palm Oil.

The Jetty capacity 20.000 dwt to 50.000 dwt for Loading Crude Palm Oil

For un-Loading Jetty capacity is 3 x 4000 dwt Barges

PT. BERLIAN LAJU TANKER Tbk. Is the Owner of this Project.

3 KESIMPULAN

Dari hasil calculation sheet di atas dapat disimpulkan sebagai berikut :a) Untuk bentangan 8 meter pipa 2" melebihi batas defleksi maksimum yang diijinkan yaitu sebesar ∆max < 66.64 mm

sedangkan defleksi maksimum pipa tersebut adalah ∆max < 50mm

b) Untuk bentangan 4 meter pipa 3/4" dan 2" yang di klem pada pipa 14" dalam kondisi aman dan baik yaitu ∆max < 0.20 mmsedangkan defleksi maksimum yang diijinkan adalah ∆max < 50mm
