| 總結: | Offshore platforms have an important role and function in offshore oil
exploration. The rig needs to be maintained in order to support that activities. One of the maintenance aspect that need to consider is the position of offshore platform. GPS technology can be used for monitoring position with high precision level. Meanwhile, the use of scientific software and distribution of reference point will affect to coordinate's accuracy. Therefore, assessment needs to be done on the coordinates that can be generated from the processing of GPS data using regional and global reference points. The purpose of this study is to determine offshore platforms� coordinates and its precise using regional and global reference points, to investigate that the coordinate value was significantly different between two reference points.
Data proccessing used GPS observation span from June 13th until June 16th
2011. This study consisted of four projects namely, global, regional, combination and per-doy projects. Global project used 7 global reference points, regional project used 6 regional reference points, whereas combination project used 13 of global and regional reference points that used on global and regional project. Perdoy project used 7 global reference points. Processing data use GAMIT/GLOBK software.
The result showed that using global reference points generate higher level
precision than using regional reference point. Global project resulted coordinates as follow : PUA1, X(-1696188,055 m ± 3,88 mm), Y(6120082,781 m ± 8,54 mm), Z(588439,1200 m ± 2,25 mm) |
