Pot Bearing: Jangkrik Complex Project – FPU


Jangkrik Field (also abbreviated as JKK) is a gas discovery made in March 2009. To date, three exploration wells (Jangkrik-1, Jangkrik-2 and Jangkrik-3) have been drilled. The selected concept is based on a subsea development with seven wells, full treatment facilities on a spread moored FPU and export line to shore at Sapi landfall. The types of bearings used for the Integrated Topside Module (ITM) of Jangkrik FPU (Floating Production Unit) are depicted in figure below:


8 fixed models with and without UPLIFT and 28 sliding guided models with and without UPLIFT are used to transfer the loads and allow the displacement and deformation of the structures.
The position of the bearings are as follows:
GG 21140 (-5880)_5005_10: A5,A6, A7, A8, A11, A13, C5, C13, D5, D7, D8, D11, D12, D13
GG 17510_5830_10: A12, B5, B6, B7, B8, B11, B12, B13, C6, C7, C8, C11, C12, D6
FX 14090_6680: A9, A10, D9, D10
FX 17240 (-3855)_5950: B9, B10, C9, C10
