DESCRIPTION
Detailed design, supply and laying of new replacement pipelines in lieu of refurbishment of existing lines. The 7 existing petrochemical pipe lines are running between the SAPREF refinery and National Port Authority at Durban harbor. The work constitutes approximately 79,1 kms of seamless carbon steel piping to be laid and welded in approximately 16km of trenches, with a minimum cover of 1,2m above the pipes. Pipe diameters vary between 6” to 14” (156mm to 365mm). The new pipe lines need to be laid in the existing servitude (on average approximately 5m wide) above, amongst or below the existing lines while the existing lines are still in operation. The construction of numerous surfaced detours to accommodate traffic during construction. The permanent reinstatement of the roads and road furniture after the pipes have been laid, as most of the pipe route is within major collector roads. Obstacles along the pipe route include but are not limited to, two major concrete lined storm water channels, 6 railway crossings, the Engen tanker gate, a bowling clubhouse and out buildings, 5 major road intersections with traffic loads in excess of 2500 vehicles per hour during peak hours and the congested Island View port complex at Durban harbor.
