Oropouche bank reclamation project

IN ORDER TO ACCOMPANY THE EXPLOITATION OF THE GAS RESOURCES OF TRINIDAD & TOBAGO, THE GOVERNMENT HAS CHARGED THE NATIONAL ENERGY CORPORATION (NEC) TO IDENTIFY AND DEVELOP NEW INDUSTRIAL SITES.


Cost of total Works: 1,870,911,000 €


Period: 08/2008 - 12/2010



A series of preliminary studies have been undertaken and as a result of these studies three possible sites seems to give the possibility to allocate new industrial parks as requested by the Government. One of these is the Oropouche Bank, located off the south-west coast of Trinidad, between Pointe a Pierre in the North, and Brighton in the south west (see figure), which has been identified as a potential site for locating gas based industries. The idea of creating new industrial sites by building reclaimed areas allows the Government to avoid consuming land side areas, thus reducing the impact on the population.

The contract awarded to Technital includes the following studies and determinations:

  • location and shape of the new island, in terms of environmental impact (on the existing sea defences, on littoral currents generated by tides and waves, on relevant river discharges, on the coastline evolution, on the littoral transport, on the swamp area located behind the coastline, etc.) and anthropic impact (on fishing activities, on the location of residential areas in terms of noise and air pollution, on the road connections, etc.)
  • industrial planning and future forecast, necessary to define the characteristics and the reciprocal position of the industries that will be installed in the new island and the relevant port facilities
  • identification of the most appropriated source of the filling material (roughly 100 million m3), analysing the different possibilities offered by Trinidad & Tobago and the neighbouring countries
  • construction methods to minimise the environmental and anthropic impacts, the construction time and, as a consequence, the final cost of the work
  • identification of the most appropriated engineering solutions (sheet piles, concrete caissons, rubble mound protections, etc.) in terms of visual impact and cost and availability of the construction material
  • mitigation measures evaluated on basis of the EIA

 

The services will be developed in five different stages:

  1. the preliminary planning of the new “industrial park” in terms of location, island shape and identification of borrow areas for the fill material – including applications for dredging and reclamation activities, and licenses for the borrow and disposal areas
  2. preparation of the Master Plan of the Oropouche bank reclamation, defining all the main aspects required to obtain all the information needed to perform the Environmental Impact Assessment
  3. preparation of the Environmental Impact Assessment Study (EIA), based on various environmental studies, marine, water quality and morphological model applications and socio-economic evaluations, and the application for the CEC (Certificate of Environmental Clearance)
  4. preliminary engineering design including all the engineering and technical aspects necessary to assess the construction cost and the total work duration allowing NEC to prepare a proper financial plan with the milestones for the construction tenders
  5. preparation of a full set of Tender Documents, including – if necessary - the definition of the size and number of contract packages, which will allow NEC to tender for the Construction Works, according to ICB (International Competitive Bidding), FIDIC Conditions of Contract for Construction, and national rules and regulations adopted in Trinidad & Tobago

 

Technital is carrying out the services with the help of a local sub-consulting firm, Lee Young & Partners, of Port of Spain (Trinidad).
