- In 1984, the Deepsea Saga underwent 6 months of upgrades totalling £19 mil. This included a £5 mil. gas lift installation, and new gas turbines. The upgrades were undertaken by Hamilton Bros Oil & Gas Ltd after their 1983 purchase; the upgrades were intended for operations on the Argyll field. After this upgrade, the rig (now a floating production unit (FPU)) was renamed Deepsea Pioneer.
- Between 1994 & 1995, Deepsea Pioneer underwent upgrades in Singapore, including the capability to pump from six wells.
- Between Jan.31 & Feb. 28, 2004, the heavy lift ship Blue Marlin drydocked the Dai Hung I, as local Vietnam yards lacked sufficient capacity.
- Sometimes confused with the North Sea Pioneer, which is often considered the first FPU (1975). At the time, Dai Hung I was known as Deepsea Saga & would not undergo FPU conversion until 1984.
- Dai Hung I was the first FPU to be used in Vietnamese waters.
