Commissioning Tests and Optimizing Clause Samples

Commissioning Tests and Optimizing. Before any work is performed on the main condenser the Contractor shall demonstrate the following to the Employer:  Provide all required certificates (equipment pressure tests, pressure gauge calibration, personnel training) as stipulated in section 3.2 above.  The Employer shall verify that the equipment on site complies in all respects to the technical data sheets provided with the tender as well as that the number of pumps, hoses, foot valves, cleaning nozzles, etc. on site corresponds with the quantities provided with the tender. If discrepancies are found an immediate commercial penalty of 20% of total contract value shall apply.  The Contractor shall demonstrate to the Employer that the HPWJ pump can supply a volume flow rate of 50 litre / min with the pump being operated at rated speed (container/stopwatch method). Note that this test do not have to be done at a working pressure of 1 000 bar. This test assumes one pump will supply one cleaning nozzle. If a single pump is to supply more than one nozzle simultaneously the pump shall maintain a minimum volume flow of 50 litre/min per each of the cleaning nozzles attached simultaneously to the pump.  The Contractor shall demonstrate that the HPWJ pump/cleaning nozzle(s) combination maintains a working pressure of at least 1000 bar. The nozzle(s) used for this test shall have a flow rate of at least 50 litre/min at 1000 bar working pressure.  The Employer shall provide the Contractor with sections of scaled titanium tube, to be removed from the same condenser by the Contractor, as directed by the Employer. The Contractor shall demonstrate to the Employer that these tube sections can be cleaned in a single nozzle pass with a reasonable improvement to cleanliness and without Significant damage to the coating of the tubes. The specified pressure may have to be adjusted based on these results.
