FPSO PTSC LAM SON – LAM SON JOC

A. Introduction

Lam Son Joint Operating Company (Lam Son JOC ) was established following a Petroleum Contract being signed between PetroVietnam (PVN) and Petronas Carigali Overseas Sdn. Bhd (PCOSB) on 7th January 2003, providing for Lam Son JOC to conduct petroleum exploration within Blocks 01/97 & 02/97 in the Cuu Long Basin, offshore southern Vietnam.

The original contract area of Blocks 01/97 & 02/97 was 11,900 Sq. km. At the end of the exploration phase Lam Son JOC relinquished area where commercial oil and gas were not discovered (about 98.9% of original contract area). The remaining areas were 115.81 sq.km for TL- DD field and 13.88 Sq.km for Ho Xam South Field.

Thang Long – Dong Do oil field is geographically located in the north-eastern part of the Cuu Long Basin and lies approximately 160 km East of Vung Tau City. Water depths across the development are around 70m.

Safety Zones :

There are Safety Zones established in principle:

• 1/ A prohibited area has been established 200 meter either side of subsea pipelines
• 2/ Areas formed by extending 500m from outer edges of THANG LONG WHP, DONG DO WHP.
• 3/ Areas formed by 1,200 m radius from the mooring turret

Vessels shall not enter these areas without the permission of OIM.

Marine Exclusion Zone:

The area has been closed zone by three circles with 2 nautical miles radius and centrals at FPSO PTSC LAM SON, THANG LONG WHP, DONG DO WHP:

Facility	Latitude	Longitude

Anchoring of Vessels in this area is strictly prohibited.

Anchorage Area:

For Export Tankers requesting to anchor, the recommended area is located southeast of the field and formed circular by the centre point with coordinates: 10°04’00”N – 108°37’00”E:

This area represents a circled shape with one nautical mile radius. Holding/anchoring ground within this predetermined area is considered good. Anchoring within the Marine Exclusion Zone is strictly prohibited. The sea water depth around the area is approximately 68 m or 223 feet.

D. Recommendations For Tanker Approaching FPSO PTSC LAM SON For Offloading Operation:

• Contact Terminal for permission to enter MEZ at least 10 NM away from FPSO on VHF CH 67; FPSO’s Call Sign: PTSC LAM SON.

• A mooring team of 5 to 6 persons will come on board Export Tanker for offloading operation. Before the team coming aboard, to save time for preparation the following should be ready:
  • Pilot combination ladder on lee side (agreed with Operation Supervisor or Mooring Master); height: 1.5m over sea level.
  • Ship crane: to pick up the toolbox from Supply Boat. Crane runner must be connected by a stinger with safety latch hook (length: 2.0-3.0m) and tag lines in case of bad weather.
  • Oxygen analyzer: to check oxygen in loading tanks before offtake under the witness of Mooring Master or his delegate.
  • Deployment of Tanker’s messenger line: 24-36 mm diam. x 220 M rope to be arranged (see attached Sketch) for Boatless Hose Transfer. The Aft maindeck windlass (in front of Accommodation Block) must be empty and ready to heave.
  • On Forecastle: winch drum with direct lead to the 76mm chain stopper must be empty to accept a 220 metres of 24-36mm messenger and 150 metres of 72mm pick-up line of the tandem mooring system. Just a short messenger 24-36mm x 30-50m to be connected to winch drum and ready to use. 1 crowbar, 1 hammer to be ready.
