NOTE ON AMENDMENT IN ENVIRONMENTAL CLEARANCE FOR SWAPPING THE CONTAINER TERMINAL TO BERTH NO.17 AND BULK (COAL) AND BREAK BULK TO BERTH NO.18 AT NEW MANGALORE PORT Submitted to Ministry of Environment and Forest, New Delhi INTRODUCTION The Port of New Mangalore (NMP), a gateway port for the vast hinterland of the State of Karnataka, is the 9th Major Port and a lagoon type harbour located on the west coast of India (12°55’N; 74°48’E). The port is located at 170 nautical miles South of Mormugao & 191 nautical miles North of Cochin Port. Presently there are 15 existing berths and one single point mooring at NMPT. New Mangalore port handles liquid and dry bulk cargo and container cargo at present. Important dry bulk commodities handled at the port that are being imported are: Coal, Iron ore fines, Limestone and Timber. Important dry bulk materials exported out of NMPT are: Iron Ore Pellets and Granite Stone. Iron ore fines used to be the major export item at the port but after ban on mining in Karnataka its export has gone down to zero. NMPT intends to develop Berth No 18 for handling bulk (coal) and break-bulk cargoes. The berth structure is already under construction by NMPT. PRESENT PROPOSAL Port has obtained Environmental clearance construction of one berth out of 4 berths in western dock arm i.e., Berth No. 15 to handle mechanized coal cargo for M/s UPCL vide letter no. J-13011/23/96-1A-2(t) part dated 04.07.2007 and for the development of remaining Berths i.e No.16, 17 & 18 has been issued by MoEF vide letter No. 11-2/2010-IA.III dated 19.09.2011. The clearance has been issued for Development of Berth No.18 as container terminal and remaining two berths i.e. No.16 and No.17 as bulk and break bulk terminals, and these berths were proposed to be developed in phased manner. In the first phase the development of Berth No.18 was proposed to be developed as container terminal as approved by MoEF. Accordingly tender was invited to select developer on PPP mode to construct and operate container terminal. But there was no response for the same. Hence Ministry of Shipping has approved the proposal to construct the Berth No. 18 to handle containers and bulk cargo with its internal resources and advised that in the 2nd stage handling equipment and other facilities shall be provided on BOT basis. The construction of Berth No. 18 is under progress and it is expected to be completed by March, 2016. Subsequently, Port engaged consultant to make feasibility and traffic forecast study for Berth No. 18. Based on the study it has been observed that the development of dedicated container terminal in the Port is unviable due to insufficient container traffic. Further, it was observed that the Coal traffic has increased and it is necessary to have a dedicated berth for coal with mechanized system. MoEF had given clearance for adjacent berths No. 16 and No.17 for developing bulk (coal) and break terminals after the completion of construction of Berth No.18. It is to submit that the bulk cargo (coal) has increased and the same is handled manually and semi mechanized form. Since Berth No.18 has to be constructed before construction of Berth No.16 and No.17, Port proposes to handle bulk (coal) and break bulk terminal at berth No.18 instead of Berth No.17. In view of above Port seek amendment in Environmental Clearance from MoEF for swap the cargo handling of Berth No.17 as container terminal and berth No.18 as bulk (coal) and break bulk terminal. EC AMENDMENT REQUESTED EC Granted Amendment in EC requested Development of Berth No.18 as container Development of Berth No.17 as container terminal and remaining two berths i.e. terminal and remaining two berths i.e. No.16 and No.17 as bulk and break bulk No.16 and No.18 as bulk and break bulk terminals terminals SALIENT FEATURES OF MECHANIZATION OF BERTH NO.18 TRAFFIC ANALYSIS Traffic for the port has been projected for next 30 years i.e. FY46 keeping in view long term investment in port infrastructure. It emerged that coal will be one of the major traffic drivers at NMPT and therefore berth 18 has been proposed to be dedicated to handling (non captive) coal cargo import at NMPT. Two scenario - Base Case and Optimistic Case have been considered in the Traffic Forecast Forecast of Coal Traffic (Million MT) Coal Traffic forecast FY16 FY21 FY26 FY31 FY36 FY41 FY46 For NMPT - Base Case 9.50 10.80 12.50 18.70 20.80 23.50 26.50 For NMPT - Optimistic 9.50 12.50 21.00 25.10 30.10 36.10 42.90 Case For Existing Berth No. 14 4.00 4.00 4.00 8.4 8.4 8.4 8.4 For proposed berths – 5.50 6.82 8.54 10.25 12.44 15.06 18.07 Base Case For proposed berths - 5.50 8.55 17.04 16.73 21.73 27.69 34.49 Optimistic Case Base case forecast is prepared by considering the present infrastructure conditions and present challenges faced by the port users. Optimistic case forecast has been carried out considering that few of the challenges like road conditions in the Western ghat and train connectivity issue faced by the users will be solved even if not all. BERTH DIMENSION The construction of berth 12 in the western dock arm is already underway by NMPT. The dimensions of the berth are as given below: Length of the berth 12 : 300 m Width of the berth : 25 m Deck level : (+) 4.66 m CD The present depth at NMPT approach channel and lagoon is maintained at (-) 15.4 m CD and (-) 15.1 m CD. It is expected to encounter rock in the lagoon area at (-) 15.4 m CD. Hence the depth in the lagoon and docks will be restricted to (-) 15.1 m CD i.e. the present maintained depth in the turning circle area. Given the depth constraints in the inner harbour, vessel sizes up to and including 80,000 DWT have been considered. MECHANICAL HANDLING FACILITIES Proposed fully mechanised coal unloading system for berth 18. Description Conveying capacity Grab unloaders(2 nos.) 2000 TPH each Jetty conveyor 4000 TPH Stacker (4 nos.) 4000 TPH Yard Conveyor 4000 TPH Belt conveyor 4000 TPH Reclaimer (3 nos.) 4000 TPH Rapid Rail Loading System 4000 TPH Grab Unloaders A fully mechanised coal unloading system has been planned for the coal berth 18. The berth will have 2 numbers of mechanical rail mounted grab type ship unloaders connected with conveyor system of required capacity for stacking and subsequent evacuation by rail or road. The unloading rate considered for discharge of Panamax size dry bulk vessels has been considered at 35000 TPD. The unloading pattern for a grab unloader gives an average unloading rate of 70 % of the peak unloading capacity. The density of Coking Coal/Thermal Coal is around 0.9 T/cum for volume calculation The grab type unloaders are most efficient, reliable and operation is environment friendly. The details of the proposed unloaders are given in subsequent chapters. The figure below shows a grab type bulk unloader. Figure: Grab type bulk unloader The required average capacity of mechanical rail mounted grab unloaders is as calculated below:- It is envisaged to provide two numbers of 2000 TPH rated capacity rail mounted grab type unloaders at berth 18 to achieve average unloading rate of 35000 TPD. Jetty Conveyor The coal berth will be provided with a stream of jetty conveyor with rated capacity of 4000 TPH running parallel on the full length of the jetty. The rated capacity of 4000 TPH will ensure that conveyor capacity will be sufficient to evacuate discharge vessels and evacuate coal from stockyard seamlessly. The conveyor system on jetty will be receiving coal discharged from the vessels and feed the yard conveyor system for stacking operation using stacker or to direct loading of coal from the jetty conveyor to the Rapid Rail Loading System (RRLS). Jetty Conveyor and associated connecting conveyors up to feeding point on to Yard Conveyors have been envisaged Double line ,(1 working & 1 standby) thus ensuring 100% redundancy in the Ship Evacuation System. Stacker Four stackers with adequate capacity (rated capacity of 4000 TPH) and outreach of 40 m will be required for stacking of coal. The stackers should have adequate slew angle and luffing angle for the purpose of forming uniform stacks of 10 m height. Stackers will be rail mounted having rail gauge of 8 m covering the entire length of the stockyard. Yard Conveyor The stockyard will be provided with a stream of trough belt yard conveyor with peak capacity of the conveyor 4000 TPH. The conveyor system at stockyard will be receiving coal from the jetty conveyor and for stacking at the stock pile using stacker. Reclaimer Three bucket wheel type reclaimers of adequate capacity (rated reclaiming capacity of 4000 TPH will be required at the stockyard. The reclaimer will reclaim the coal and feed the conveyor system for onwards evacuation through RRLS. The capacity of the reclaimer has been estimated considering 100 % evacuation of coal through RRLS. The figure below shows indicative pictures of stacker and reclaimer which are used commonly in the stockyard. Figure: stacker – reclaimer EVACUATION The evacuation shall be mainly through rail. For faster evacuation of coal, a Rapid rail loading system (RRLS) with peak capacity of 4000 TPH is proposed adjacent to the existing UPCL RLS.
