As part of building the third Keur Momar Sarr water plant (KMS3), the Chinese company CGCINT entrusted our teams in Senegal with the unloading operations for pipes with a diameter of 1,500 mm, in addition to customs clearance and transportation from the Port of Dakar to the trenches on site, i.e. a 55 km-long section on the Thiès-Mékhé route.
To do so, the Logistics and Port Operations department, in collaboration with the Bolloré Logistics technical teams, established an effective operational strategy to manage this large-scale project. The movement plan was broken down into two major phases.
The first phase was the upstream production of metal rails in the form of cradles with a width of 3.40 metres and height of 1.00 metres, for secure loading of the pipes onto the lorries.
This mechanism, designed by our operational teams, secured the transportation of the outsize pipes, unloaded from the first ship that arrived at the Port of Dakar in late December 2017.
The second phase required the implementation of an adjustment system guaranteeing the integrity of the transported equipment. For each lorry, wooden beams of the inside width of the rails in addition to rafters adjusted to the contours of the pipes were positioned to prevent friction and damage to the equipment. On the lower bed of the first two pipes, a set of four ropes was inserted between them to prevent all contact between the pipes of the upper bed and the pipes of the lower bed.
A dedicated convoy of 35 equipped lorries and the use of four PPM Reach Stackers cranes enabled the items to be moved from the port to the delivery site in record time, minimising the intermediate storage period insofar as possible. In total, Bolloré Logistics will provide logistical management for a batch of 6,740 pipes distributed over six or seven ships.
KMS3 is a structural project for the State of Senegal, implemented by Société Nationale des Eaux du Sénégal. Further to KMS1 and KMS2, this third water plant will have a final capacity of 200,000 m3 per day and, by 2035, will meet the drinking water needs of the Dakar region and the areas in the path of the Lake Guiers pipe. KMS3 is due to be commissioned in the first quarter of 2020.
