CSBD WRITEUP

White Tiger Field (Bạch Hổ ), Cuu Long Basin, Vietnam

Mencast Subsea was contracted to commence and complete an inspection on PVD 5 at White Tiger Field off Vung Tau, Vietnam.

These inspections (UWILD) of MOPU (Mobile Offshore Production Units) takes place every 2.5 years. The reason for this being done is to allow the vessel to continue working at location without disrupting operations and heading to a dock.
