In order to increase the coal-handling capacity in India, a new port was constructed at Ennore, about 20 km north of Chennai (formerly Madras). Total construction costs of the new port were estimated at US$ 380 million. The assignment was initiated by Haskoning’s Paradip-Ennore Coal Transport Techno-Economic Feasibility Study (1988-1990).
A master planning and ports engineering and construction design exercise was commenced in 1994. The project consisted of 4 km of rubble mound breakwater in water depths of up to 12 m, dredging of 13 million m3, reclamation of 5 million m3, 600 m coal wharf for 65,000 dwt bulk carriers, 3 jetties for small craft, a port access road, port railway sidings, port buildings, various port utilities and the procurement of 3 tugboats of 35 tons board pull and 2 pilot boats. The planning and design of the port was facilitated by a comprehensive transport demand study for the port and several field investigation programs. Fast- and real-time ship simulations, (cyclonic) wave hindcast studies, probabilistic and mathematical modelling of breakwater structures, two- and three-dimensional breakwater model testing and risk analyses related to breakwater design, ship manoeuvring studies and a separate logistics study on the rock supply from quarry to site were all carried out. The tender and supervision phases of the Ennore Coal Port Project comprised the following components:
- preparation of contract specifications and drawings (tender documents)
- prequalification of contractors, supervision of, -a.o.- rock quarrying and transportation for breakwater construction, roadway access and fencing, dredging, wharves construction
- contract management, project & site management
- supply of floating craft, supply and installation of navigation aids
The design and engineering aspects, including the general planning and preparation of tender documents and prequalification of contractors for 15 separate construction and/or supply contracts were completed in 1996. Since 1996, the construction/ supply contracts were commenced immediately after this and were completed in 2000.
