Saramacca River, Suriname

Replacement & installation of pipelines Staatsolie Maatschappij

Staatsolie Maatschappij Suriname has contracted Visser & Smit Hanab to replace the existing high-pressure pipeline and to install extra pipelines under the Saramacca River, to the west of Paramaribo. The project includes three horizontal directional drillings. Before drilling could commence, V&SH carried out preparatory work, such as assembling the strings, for the pipelines that have to be inserted later.

DrillRig
250 ton
Soil
Clay (Sand, Silt)
Material
HDPE, Steel
Diameter
16 inch, 10 inch
Length
350 meter, 373 meter, 720 meter

A 350-metre drilling (16” HDPE pipe) forms part of a connection between La Prevoyance and Catharina Sophia and the other two drillings are for a connection between Sarah Maria and Josie Kreek. The drillings at the latter location have lengths of 373 metres (bundle of 2 x 16” pipes, one 12” and one 8” HDPE pipeline) and 720 metres (10” steel pipeline) respectively. A 250-tonne rig was used for drilling.

 

Visser & Smit Hanab is responsible for the entire project, from design to execution. When the drilling is completed, a great deal of work will have to be done to install the associated manifolds with scraper traps and tie-in.

 

The project will continue until the end of November / beginning of December 2015.
