Land of Sharal Banskhali > Considered for Economic Zone

< Dakshin Bahar Chara Plot Considered for Economic Zone

Preferred Site Location – Chhanua, Banshkhali

• 

  Good water-front access (Kutubdia Channel).

• 

  Sufficient land available to develop up to 5000MW – local government and private.

• 

  Critical TL and PL infrastructure relatively close, access to LNG-sourced gas pipeline network.

Land Ownership Situation – Project Site

• 

  Green = Freehold Private Property

• 

  Yellow = Local Government Owned & Controlled Property

• 

  Landholdings approx. 70 acres (30ha) privately owned, with a further approx. 150-200 acres (60-80ha) government owned and for lease.

• 

  About 15 individuals own rights over approx. 70% of private land.

• 

  Discussions with key land owners as well as local government on-going and positive

Securing land rights will involve (i) acquisition of private lots, and (ii) surrounding foreshore rights via long term lease from local government.

SITE INSPECTION

Introduction:

This project is known as the Chhanua G2P Project that will be based on the installation of 2 x 500MW GE 6F.03 CCGT Floating Power Plants (FPPs)in Bangladesh. It is proposed to install a 1,000 MW floating power plant at a site at Chhanua on the Kathkhali Khal (canal), a tributary that empties into the Kutubdia Channel. It is understood that no existing infrastructure of any nature exists in the area and that access by road is very limited. This situation presents several challenges to the project for its development, construction, installation and operation.

Inspection of this site will be undertaken having performed some very preliminary work on a site arrangement for the initial 1,000 MW installation, such that it can be visualized more exactly when on location. Considering the remoteness of the site and the lack of access roads sufficient to support heavy trucks and equipment transport for development of the site the only viable means of access for this purpose will be by water. It is thus presumed that all equipment, construction machinery, materials and labor will necessarily be transported by barges and boats. This will include machinery and equipment such as cranes, pile drivers, electrical generators, dredgers, draglines, etc. plus support facilities for labor and personnel and associated services.

While the FPPs will be constructed at a shipyard remote from the site, work will need to be simultaneously ongoing to construct a stilling basin and associated infrastructure to receive and install them upon delivery. How this will be undertaken needs to be carefully thought out considering water depths required to provide access from the sea for tugs and barges to deliver materials and supplies, a dock and large lay down areas for storage, power distribution, lighting, man camp and finally sufficient channel width to deliver the FPPs to their operational location in the basin and its eventual protection.

Inspection of the site will consider these factors as well as issues such as rights of way for the gas pipeline and its connection point, rights of way for the high voltage transmission lines, plant cooling system determination considering water quality and temperatures and the method of intake to the FPPs and its discharge, both for the initial 1,000 MW installation and any future expansion.

Information & Data Needs:

• 

  Any bathymetric data for the adjacent river and channel.

• 

  Geotechnical data for the site (coring results, sediment classification).

• 

  Aerial photography of site over a range of years.

• 

  Tidal ranges, current velocities and seasonal level/depth data.

• 

  Seismic data for the Chittagong region.

• 

  Environmental data for the area (wind, wave & current offshore) including a 100 year storm (monsoon).

• 

  Seasonal precipitation and temperature data.

• 

  Seasonal water temperatures.

• 

  Permitting requirements; environmental, operational and any other permits.

• 

  Gas pipeline specification; pressure and design capacity and location of connection.

For Construction Purposes:

• 

  A meeting with a substantial local civil works contractor will be helpful for discussions on a construction plan and functional costing information.

• 

  Any available geotechnical data for the area to determine piling requirements.

• 

  Discuss importation and/or transshipment of materials at Chittagong port.

• 

  Substantial dredging of the channel from the sea and adjacent waters around the site.

• 

  A determination of available local equipment for dredging, spoils disposal, etc.

• 

  Produce a preliminary plan of the site for its development and construction program.
