CA TAM FIELD DESCRIPTION

The “Ca Tam” Oil Field is located at Block 09-3/12, approximately 160 km South East of Vung Tau City, offshore the Socialist Republic of Vietnam. It belongs to Joint Venture of Vietsovpetro, PVEP and Bitexco. There are two wellhead platforms  . (CTC1  and CTC2) in the “Ca Tam” Oil Field  Development Plan. The CTC1 platform will be installed in the first stage and the CTC2 platform-  in future.

The CTC1 wellhead platform consists of Jacket with Boat Landing, MSF – Module Support Frame (Sub Main Deck), Topside with Vent Boom and Helideck. There are 12 well slots on the CTC1 platform. CTC1  platform topside facilities are able to accommodatethe processing of the well stream fluid, gaslift gas and water injection requirements as well as other utility systems.

The CTC 1   platform is connected to the nearest existing platforms located at the White Tiger, White Bear and Dragon oil fields, block 09-1, via subsea pipelines and cables.  Produced liquid of the CTC1  platform will be transported to the  RP2 platform at Dragon oil field for further processing. Separated gas – to CCP platform via BK14 (at White Tiger oil field) and GTC1  (at White Bear oil field) platforms. Gaslift gas and water injection for CTCl will be supplied from GTC1 platform via subsea pipelines.

The CTC 1   platform is designed as a hub platform which will be connected to and received products from the CTC2 platform via subsea pipelines and cables in future.

In first stage, the “Ca Tam Oil Field Development Project” includes 5 sub-projects called  “CTC1   Wellhead  Platform”,   “Subsea   Pipelines  and  Cables”,   “RP2 Modification”, “GTC1 Modification” and “BK14 Modification”.

This report presents the results of the external survey for PTT Public Company Limited pipelines survey within the inspection program covering the following pipeline and structures:

1. 32’’ x 171.3 km long spur pipeline from BKT to ERP
2. 24’’ x 160.8 km long trunk pipeline from ERP to KNM
3. 24’’ x 18.5 km long connecting pipeline from ACPP to 42” PLEM
4. 42’’ x 260.2 km long spur pipeline from JDA KP60.4 to ERP
5. 24’’ x 38.1 km long connecting pipeline from GBS to 3^rd Pipeline PLEM

The main project contractors employed to perform the PTT external pipeline survey was PTSC Offshore Services JSC (POS), who utilised PTSC’s vessel (PTSC Binh Minh), operating one (1) work-class and one (1) observation-class ROV. POS sub-contracted survey and navigation services to Green Star Positioning JSC for survey, data processing and navigation spread and Fugro Singapore Pte Ltd for CP (Cathodic Protection) survey.

The inspection and survey tasks were performed as per the requirements outlined within the documents Appendix 3 – ROV Subsea Pipeline Survey Procedure and Appendix 4 – ROV Subsea Structural Survey Procedure of POS-PTT-OPES-001.

The routine inspection video and anomaly video clips were recorded utilising Visualsoft software suite in (ASF) advanced systems format and event logs were recorded using Visualsoft Eventing module.

Summary of the pipeline survey work scope consisted of:

• General visual inspection of fiv (5) pipelines
• Damage (including leaks)
• Debris (which may affect the integrity of the pipeline)
• Freespan suspensions (which may affect the stability of the pipeline)
• Movement (lateral or vertical)
• Level of cathodic protection

During the course of survey, additional scopes to measure gas leaks at KP 131.194 tie-in skid of 32” pipeline BKT – ERP and KP 136.588 PLEM of 42” pipeline JDA KP60.4 – ERP was requested by the Client. Leak measurement tasks were carried out as per Gas Measurement Procedure. The Client also requested to have a look at the Tantawan PLEM for diver access.

All survey and inspection tasks were conducted utilising PTSC’s vessel M.V. PTSC Binh Minh and using the SMD Quantum 4 work class ROV and Seaeye Tiger 865 observation class ROV. Digital video and data recording and survey data acquisition were performed using QINSy and Visual Soft software systems.

The Pipeline Survey commenced on the 15^th August 2018 and completed on the 25^th September 2018.
