| Summary: | Skidway owned by PT.McDermott Indonesia is located in Batu Ampar,
Batam is a plate supported on piles or bore pile. Skidway main fuction is as a
board fabrication for heavy weight structures such as tower, oil rig platform, and
jacket. Skidway current capacity is 24.000 tons. Facing the development of oil
and gas, skidway capacity needs to be improved. This final project was conducted
to get the new design for skidway with a total bearing load of 30.000 tons and a
point load of 5.000 tons. Skidway is divided into 2 areas where design load for
Area 2 is increased by 30% due to load out process.
Skidway design process starts by obtaining design load as a basis data for
planning. N-SPT data from soil investigation was analyzed to obtain pile, bore
pile bearing capacity and soil modulus of elasticity. Comparison between pile
bearing capacity and design load will give the size of single panel plate which is
used as distance between each pile. Plate design process is based on the provision
of SNI 03-2847-2002. An initial design stept is done in order to determine the
approximate dimension of the structures as an input in the program SAP2000.
SAP2000 output such as moment, shear load was manually processed to obtain
the design for reinforcing steel size and spacing.
The result of the modelling process give maximum moment of 1749 kNm &
-822,2 kNm (Area 1) and 2968,4 kNm & -1753,4 kNm (Area 2). The design result
is 0,5�0,5 m pile with 1 m distance between each pile and jacked to -7,5 m below
ground level (Area 1). Bore pile with diameter of 1 m is used with distance
between each bore pile is 1,5 m and bored to -8 m below the ground level (Area
2). The design of reinforcing steel for 1 m thick plate is � = 25mm |
