FSO PTSC Bien Dong 01 – Hai Thach Condensate

A. Introduction

BIEN DONG PETROLEUM OPERATING COMPANY (BIEN DONG POC) is Operator of Block 05.2& 05.3, and PTSC PPS operates the FSO PTSC BIENDONG 01 on BD POC’s behalf.

Block 05.2 & 05.3 located in the Nam Con Son Basin offshore Vietnam, 184 Miles (340 Kms) south-east of Vung Tau province. The Nam Con Son Basin has several important fields with production from Dai Hung Condensate Field, and Lan Tay Gas Field, as well as further gas and condensate Rong Doi.

Bien Dong development is comprised of the following:

• A Floating Production Storage and Offloading (FSO) system.
• A Production and Quarter Platform (PQP).
• The Well Head Platforms (WHP-HT and WHP-MT)
• A Subsea Pipeline End Manifold (PLEM)
• Subsea electrical power cables and control system
• Infield flowlines

Associated gas will be separated on the PQP. The separated gas will be delivered to the Nam Con Son pipeline through the sub-sea pipeline, and Condensate will be piped through the infield and flexible risers to the FSO and to be stored and offload from the FSO. The FSO located approximately 2,2km NW from the PQP.

C. Terminal Limits, Navigation Guidelines

Terminal Limits

The condensate field facilities are located in the following coordinates (in WGS 84) :

Safety Zones : There are Safety Zones established:

• 1/ A prohibited area has been established bounded within a 500 meter radius from a line joining the above positions.
• 2/ 04 areas formed by extending 500m from outer edges of PQP/WHPs and FSO. Vessels shall not enter these areas without a Mooring Master on board.

Restricted Zones:

There are 04 Restricted Zones with radius of 02 NM surrounding PQP/WHPs and FSO. Within a restricted zone, anchoring of vessels is strictly prohibited.

Pilot embarking/disembarking area, Anchorage area:

In case of weather permitting, the vessel (s) is requested to call to below position for embarking/disembarking Pilot and lifting group:

Latitude:          08° 05’ 10” N

Longitude:      108° 52’ 22” E

Anchorage Area:

For tankers requesting to anchor, the recommended area is located 03 NM north-west of the FSO PTSC BIENDONG01 and is centered on the following position:

Latitude:          08° 05’ 10” N

Longitude:      108° 52’ 22” E

This position represents the center of a circle with a radius of 1 nautical mile.

Holding/anchoring ground within this predetermined area is considered good.

However, due to the sea water depth around the area is approximately 130 m, the weather condition and safety precautions, therefore, should be considered very carefully by Master of export tanker whenever make the decision on bringing his vessel to anchor.

Aids To Navigation:

The WHPs, PQP and FSO are provided with navigation lights Morse “U” with specification in full compliance with IALA (International Association of Lighthouse Authorities) recommendations for offshore installation.

Nautical Charts:

British Admiralty (BA) Chart Numbers 3482 for approach Biendong Terminal. BA chart number 3986, 1261, 1016 for approach off Vungtau Pilot Station.

The Navigator is referred to published sailing instruction for the area through British Admiralty ( BA) China Sea Pilot Volume 1.

D. Recommendations for Tanker Approaching FSO PTSC Bien Dong 01 For Offloading Operation:

• Contact Terminal for permission to enter MEZ at least 10 NM away from FSO on VHF CH 16/10/12 (for FSO); FSO’s Call Sign: PTSC BIEN DONG 01.
• Without Mooring Master on board, all vessels are requested to keep a safe distance (at least 2 NM) from the following installations within MEZ:

  WHP-MT 1	07°55’46.68”N
  	108°47’31.02”E
  WHP-HT 1	08°02’34.52”N
  	108°55’40.69”E
  PQP-HT	08° 02’38.92” N
  	108° 55’ 40.96” E
  FSO-PTSC BIENDONG 01	08° 03’ 02.31 N
  	108° 54’ 30.61” E

• 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.
  • On poop deck: Aft poop deck windlass, 2 heaving lines, 1 chain stopper, 1 plier, 1 crowbar, 1 hammer must be ready for picking up towing pendant wire.
  • At Port side manifold: a reducer 16”-12” to be fixed for offloading hose connection.
• In case of bad weather and request of deviation is granted, the pilot boarding ground is Mui Vung Tau (10°15’N; 107°05’E). Please contact Vung Tau Port Control on VHF 16/09 from distance 24NM, 12 NM, 6 NM to the POB point for more information and instructions.
