2.3.2 PS01 and the proposed electric motor shall be suitably designed towithstand high levels of continuous rainfall.CQUCoal Surface Operations Transportable Pump starter – PS01Revision 0 Page | 72.4 Essential data of the pump2.4.1 The pump is required to have a maximum flow rate of 200 l/s.2.4.2 Actual impeller diameter: 416 mm2.4.3 Type of impeller: 2-CHANNEL2.4.4 It is expected that it will have to pump water with a maximum head of40 m.2.4.5 The tenderer is not expected to look into the coupling details of thepump with the motor and hence it may be considered as client’sresponsibility.2.5 Proposed Electrical Motor Requirements2.5.1 The electric motor shall be rated at 415VAC2.5.2 The tenderer must recommend the power rating to suit the applicationin the final design2.5.3 The electric motor is to replace an existing diesel pontoon mounted, fillpoint pump.2.5.4 The electric motor shall be capable of withstanding the environmentalrequirements as described in section 2.3 of this document.2.5.5 The proposed electric motor shall have a minimum IP rating of 65(AS:60529)2.5.6 The use of a 6-wire or 3-wire type motor shall be justified by thecontracting team. (This will have implications on the Drive system)2.5.7 Justification shall be provided by the contracting team which details thereasons and considerations made for the selection of the motor type,size, duty, starts/stops per hour etc.2.5.8 The use of the proposed motor shall be agreed by the nominatedCQUCoal representative and the contract team as early as possible.2.5.9 The tenderer is not expected to design the mounting arrangements ofthe motor on the pontoon and hence it may be considered as client’sresponsibility.CQUCoal Surface Operations Transportable Pump starter – PS01Revision 0 Page | 82.6 Design of Drive System PS012.6.1 The power supply of the drive system is to come directly from an outletof an assumed upstream substation2.6.2 The drive system is to be mounted on a suitable skid to be bankedadjacent to the water body and no further than 30meters from theelectric motor/pump2.6.3 The drive system shall be capable of withstanding the environmentalrequirements as described in section 2.3 of this document2.6.4 The Drive system shall have a minimum IP rating of 562.6.5 The drive system shall limit the short circuit fault level inside theenclosure(s) to less than 5kA. Ideally, the fault level will be reduced aslow as practically possible.2.6.6 PS01 will need to include a suitable Electronic motor starter or VariableSpeed Drive, capable of powering the proposed electric motor2.6.7 Depending on the type, size, usage and duty cycle of the proposedmotor, suitable motor protection should be provided. Protectivedevices in the design shall be capable of providing the following formsof protection as a minimum:a) Motor Overload Protectionb) Short Circuit protectionThese may be achieved through the use of devices such as MCCBs orfuses.2.6.8 In accordance with AS2081, other methods of protection should beincluded in the design where applicable.2.6.9 The supply substation has earth leakage protection installed so it is notnecessary to install additional earth leakage devices on PS01.
