V. PROJECT DESCRIPTION
1. General
The Project Site consists of four main areas: the refinery, the product tank farm, the marine loading facilities at the jetty and the SPM and seawater intake and outfall facilities. These areas are joined by interconnecting piping with an adjacent service road.

1. General
The Project Site consists of four main areas: the refinery, the product tank farm, the marine loading facilities at the jetty and the SPM and seawater intake and outfall facilities. These areas are joined by interconnecting piping with an adjacent service road.
2. Overall Site Plan
The general layout of the facilities is shown on the Overall Site Plan. The area of the overall site is calculated to be approximately 232 ha, made up as follows:- Overall Refinery Process, Utility and Offsites Facilities; about 110 ha.
- Crude Tank Farm and Flare Area: about 42 ha.
- Product Tank Farm: about 36 ha.
- Seawater intake, Waste Water and Crude Oil Pipelines: about 4 ha.
- Interconnecting Pipelines, road and right of Way: about 40 ha.
- In addition, the Product Harbour Service Area will occupy about 135 ha.
2.1 Refinery Areas
Refinery areas consist of process units, utilities, crude tank farm, intermediate tankage, check tanks, flare, effluent treament, administration buildings. The individual process units are linked with elevated piperacks and low level pipetracks. Provision is also made for future units.
2.2 Product Tank Farm Area
This area is located approximately 2.0km from the jetty heads and 6.0km north of the Refinery. The location is on an elevated plateau at 18.0m HN-72. The central access road through the tank farm is aligned with the interconnecting pipeline service road. Tankage layout and bunding requirements shall conform to the requirements of Equipment Spacing Standard. Access to the truck loading area shall be separate from the access to the tankage area. The flare and LPG spheres are located with regard to the prevailing wind. The central grade mounted pipetrack, which runs through the Product tank farm carries all the lines that connect the Refinery to the Product tank farm and Jetty loading.
2.3 Marine Loading Facilities
The marine loading jetty, which is located to obtain maximum storm protection from the breakwater, consists of three jetty heads each with two berths. One head is designed for ocean-going ships up to 30,000dwt, and two are designed for coastal ships up to 5000dwt. The jetty layout is arranged to allow good access for maintenance and firefighting and the necessary security and support services at the entrance.
2.4 Interconnecting Pipelines
This pipeway carries the Refinery product and service pipelines on concrete sleepers at grade between the Refinery and the Product tank farm and on the Jetty loading area. The pipeway is approximately 6.0km in length between Refinery and Product tank farm and 2.0km between Product tank farm and Jetty head. A service road is provided for maintenance and access to the pipelines and cables. Expansion loops and surge load anchors shall be taken into account without creating low point pockets in the piping systems. The elevation of the product pipelines vary between 6.0m and 18m HN-72.
2.5 Seawater Intake and SPM
The seawater intake and discharge and the SPM are located in Viet Thanh Bay. The cooling water lines and crude oil lines come ashore in separate corridors. Due to the existing terrain and the requirement to not breach the natural sea defence, they will be buried for part of the route to the refinery fence. An access track is provided alongside the Seawater pipelines.
