Project Relief

The cost of decommissioning may be considerable, and comes of course at the point when the project is no longer generating funds. Some source of funding will therefore be required, and this may be available from the profit of other projects, from a decommissioning fund set up during the field life or through tax relief rolled back over the late field production period.

The couphng equation is a vapor mass balance written at the vent system entrance and provides a relationship between the vent rate W and the vent system inlet quahty Xq. The relief system flow models described in the following section provide a second relationship between W and Xo to be solved simultaneously with the coupling equation. Once W andXo are known, the simultaneous solution of the material and energy balances can be accomplished. For all the preceding vessel flow models and the coupling equations, the reader is referred to the DIERS Project Manual for a more complete and detailed review.

Initially there were attempts to quantify and project magnitudes of power shifted and relief provided to the capacity resource requirements. Ultimately the shifting of load became embedded in the subsequent forecast and became harder to identify.

Assumption (f) of isothermal flow means that the method is different to the homogeneous equilibrium model (which assumes adiabatic flow). The difference between the two assumptions is usually small. The isothermal flow assumption gives a slightly simpler method and yields a conservative low value of G for relief sizing purposes. The DIERS Project Manual1111 gives the alternative version of Tangren et al/s method, which assumes adiabatic flow and is therefore equivalent to the HEM. 

At present, there is no comprehensive gujdance on this topic However, it has been the subject "of much, research, particularly by the Design Institute for Emergency Relief Systems (DIERS) of the American Institute of Chemical Engineers (AlChE). As a result, the DIERS Project Manual[1] (a, record of the DIERS research) and a considerable number of papers have been published. This Workbook summarises the main hand calculation methods (which do not.need. the use of a computer) available as a result of this work and their limits of applicability. A number of worked examples are given to. help the reader understand their application. The experimental information required to size an emergency relief, system properly is also discussed.. ... 

The Baku-Tbilisi-Ceyhan and the South-Caucasus-Pipeline projects will be arranged in a 22-meter wide construction corridor for two parallel pipelines buried in a 2.2-meter deep trench. This alone illustrates the complexity of facilitating pipeline systems in regards of environmental issues and the complicated morphological mountainous relief.
