Automation for Offshore Platforms and FSOs
Since 2013 TDL has worked on control and safety systems offshore Vietnam: on Vietsovpetro's Central Compressor Platform and
By system
Process control and ICSS
The legacy
PLC-5 on JVPC's N1 wellhead platform migrated to ControlLogix with central SCADA communication, with the site work carried out from the FSO; for Vietsovpetro'sBK-20 andBK-21 wellhead platforms, the main ICSS materials (ControlLogix, AADvance, FactoryTalk View) supplied with engineering consulting.Fire and gas
On the Riserblock Central Processor Platform, the Sieger fire and gas system upgraded to an AADvance safety system with fault-tolerant I/O on an EtherNet/IP DLR, new fire and gas detectors and control panels; for the Central Compressor Platform, AADvance, gas and fire detectors and Rittal enclosures supplied with engineering consulting for a SIL 3 process safety system for the fire and gas functions.
Compressors
On PVEP's DMDP-A platform, the controls of the booster gas compressor (2023) and the gas lift compressor (2024) moved from ControlNet to EtherNet/IP, with only discontinued and end-of-life parts replaced and FAT at TDL's workshop before the shutdown; on Vietsovpetro's LP compressor, Siemens S5 and Bently Nevada 3300 replaced with ControlLogix, PanelView HMI and Rockwell Automation vibration monitoring, with testing witnessed by Bureau Veritas.
Utilities: CO2, water maker, EDG and switchgear
On Vietsovpetro's Central Compressor Platform, the CO2 control system upgraded to fully redundant ControlLogix, and the emergency diesel generator (EDG) control and switchgear monitoring moved from SLC 500 to CompactLogix, installed 1:1 in the existing cabinets within an
8-day platform shutdown; on a JVPC platform in the Rang Dong field, the RO water maker moved from SLC 500 to CompactLogix 5380 without changing the field wiring.Maintenance and functional tests
On MODEC's FSO Rang Dong MV17, a new program loaded into the Omron CJ1M PLC of the Hi-Foam control system, with the functional test and commissioning on board; on PVEP's Thang Long – Dong Do platform, ICSS maintenance and repair with program backups, logic programming and new workstations.

Frequently Asked Questions
Which offshore operators has TDL worked for?
Vietsovpetro, JVPC, PVEP and MODEC, from 2013 to 2026: on compressor, wellhead, processing and utilities platforms and on the FSO Rang Dong MV17.
Can a platform control upgrade fit within a planned shutdown?
On Vietsovpetro's Central Compressor Platform in 2020 the new EDG and switchgear controllers were installed 1:1 in the existing cabinets within a shutdown of up to eight days. On PVEP's DMDP-A platform the FAT was done at TDL's workshop before the offshore shutdown, and modules still in active lifecycle were kept to keep the shutdown short.
Has offshore work been witnessed by a third party?
Yes. On the LP compressor upgrade on Vietsovpetro's Central Compressor Platform in 2018, Bureau Veritas witnessed the testing and gave third-party witness certification.
Planning control system work on a platform or an FSO?
Speak directly with our engineers. Send your RFQ, scope of work or drawings: the engineers who program and commission the systems read them and reply, from the first review of the existing system to the proposed solution.
