Effective solutions and lessons learnt from using Tender Assisted Drilling Rig (TAD) for drilling on deepwater fixed platform of Bien Dong 1 project
Abstract
The paper analyses some advantages and disadvantages of the first-ever Tender Assisted Drilling Rig (TAD) in Vietnam and the efficiency of its utilisation after three-year operation for Bien Dong 1 project’s field development at Hai Thach and Moc Tinh fields (Nam Con Son basin). On that basis, the authors propose solutions for the rig operational mode identification based on the colour code system, at the same time calculate and select the mooring system and the design of the PTB with considerations of the weather factors in the area in order to improve the efficiency and safety in the rig operations.
