Erection and commissioning

The following precautions are to be taken while storing rubber lined pipes prior to erection and commissioning. 

The costs of erection and commissioning of even a very complex micro structured reactor plant are, of course, comparably small. This means that the basic design of a micro structured reactor plant is extremely expensive and attention should be given to minimizing costs, for example, by the application of calculation sheets, the standardization of complete process units or the use of process simulation or planning tools such as AspenPlus . The reduction of this cost factor remains a future task of micro technology. 

Fees to erection and commissioning engineers and their teams may be included in orders for equipments,... 

Erection and commissioning of the plant equipments and machineries and reaching rated output from the plant,... 

Training may also be arranged on a running unit or given on the plant being erected and commissioned. This may be charged separately on a man-day basis by the consultants,... 

However, cost of purchase and taxes have already been incurred/paid on obtaining and installing these equipments (but they may not be required now) while licensing fees, royalties for process know-how, and catalysts charged in the reactors are to be paid on a recurring basis. The erection and commissioning expenses for the equipment have already been incurred. 

Erection and Commissioning shall be included in the scope of supply. Performance guarantee test shall be for 72-168 h of continuous run (3-7 days) or for producing five batches of the product as per specifications in case of batch process. 

Obtaining necessary statutory clearances for erecting and commissioning. 

This document shall again be studied by senior experienced persons very carefully in a critical manner from following points of view (before the equipments are fabricated, erected, and commissioned. It thus saves costly changes which may... 

External insulation and cladding may have to be done by purchaser after statutory inspection is carried out. It shall be the responsibility of the vendor to get statutory approval for the entire set-up (boiler and accessories). Erection and commissioning of the boiler shall also be the responsibility of the vendor. 

Manuals for erection and commissioning of the plant are prepared by consultants—except for specialised proprietary items or machines. The latter are supplied with the items. The scope of supply by vendor and obligations of the purchaser shall be very clearly defined (e.g. keeping the civil foundation, water, and power supply and instrumentation air ready before the machinery is delivered at site). 

The full study procedure of the HAZOP study shall be carried out now before proceeding with erection and commissioning. This will avoid costly changes in the plant later on and will also help to assess the operability of the plant. 

Completion of various project activities in time/as per scheduled dates is a very important matter. Typical activities relate to obtaining all statutory clearances, acquiring land, arranging water and power supply connections, completion of civil foundations and other infrastmctures, procuring necessary plant items and machinery, and their erection and commissioning, followed by stabilising the production runs. 

To evaluate the relative worth of any capital cost impacts which do not show up in the item prices. These may for instance include costs of transport, erection and commissioning, associated foundations, electrical reticulation, instrumentation and control gear, and pipework. Normally the parallel commercial appraisal, excluded from this scope, will include such factors as impact of terms of payment, duties and taxes, foreign exchange, import/export permit availability, and terms of contract. The interface between the engineering and commercial appraisals needs to be co-ordinated. 

The vendor should agree to provide site assistance for erection and commissioning—either free or on a chargeable basis to be written in offer). 

Every dust collection plant with its ancillary equipment must be properly operated and serviced so as to enable it to perform its duties at all times. The manufacturers of such plant should accordingly, when erecting and commissioning it, supply the user with the following documents ...
