SRK Consulting: Project No: 439414 Staatsolie Pipeline EIA – Draft EIA Report Page 13
Two canals lie between the Staastolie refinery and the Suritex depot, viz. the Tout Lui Faut
canal just north of the Staatsolie refinery and the Saramacca canal just north of the OGANE
site. The Suriname River is used by a wide range of vessels of various sizes in this section.
3.3 Description of the proposed project
3.3.1 General description
The project entails the construction of three underground pipelines between the Staatsolie
refinery at Tout Lui Faut in the south and the SOL-Beekhuizen and Suritex depots in the north,
via the SOL-SUHOZA and OGANE sites, as per the specifications provided in Table 3-1:
• One diesel and one gasoline pipeline will run between the Staatsolie refinery and the SOL
and Suritex product storage depots, to convey diesel and gasoline from the Staatsolie
refinery to SOL and Suritex; and
• One LPG pipeline will run between the Staatsolie refinery and OGANE, to convey LPG
from OGANE to the Staatsolie refinery.
Table 3-1: Proposed pipelines from Staatsolie Refinery
Pipeline Between refinery and Diameter Pressure rating Pump capacity
Diesel SOL and Suritex 10” 300 psi 2 000 bbl per hour
Gasoline SOL and Suritex 8” 150 psi 750 bbl per hour
LPG OGANE 4” 300 psi 4 tons per hour
The three pipelines will follow a single alignment. In addition, a fibre optic cable will be
installed alongside the pipelines.
3.3.2 Pipeline alignment
The pipeline will be laid underneath and just in-stream of the western bank of the Suriname
River, using Horizontal Directional Drilling (HDD) (see Figure 3-2). Continuous sections of up
to 1.64 km will be drilled. At the beginning and end of each drill section, an entry and/or exit
point will be located at the surface, where the drill pad will be placed and from where the
pipelines will be pulled into and out of the drill hole. At these points, the pipelines will lie
approximately 3 m below the surface, while between entry and exit points the pipelines are
expected to lie up to 30 m below the riverbed, depending on the HDD section and ground
conditions, which will be finalised during detailed design.
The pipeline will be laid in four drill sections with five entry and/or exit points, which are
located:
1. North of the Jules Wijdenbosch bridge;
2. On the Bruynzeel site at the confluence of the Saramacca Canal and Suriname River,
south of the Dalian company;
3. On the riverbank near the SOL jetty in front of the OGANE property;
4. On the riverbank between MNO Vervat and Kuldipsingh in front of the SEMC property;
and
5. On the riverbank adjacent to and north-east of the Staatsolie refinery (see Figure 3-1).
From the exit near the SOL-Beekhuizen jetty, the LPG pipeline will be routed on land towards
OGANE, and branches/offtakes of the diesel and gasoline pipelines will lead to SOL-
Beekhuizen.
