Derrick Shakers

The existing Derrick shakers are to be re-used. It is currently proposed that shakers will be free issued to GN for refurbishment prior to incorporating in the works. Required refurbishment includes:
• Strip down
• Sand blast
• Reweld any cracked components
• Paint using approved zinc silicate primer and epoxy topcoat system
• Reassemble
• Fitment to shaker module skids
Should any new parts be required these will be reimbursed at actual cost plus 15%. Any welding of cracked sections will be a variation at the agreed rates in the Schedule of Prices. All other work – i.e. strip, paint reassemble is based on a lump sum.
GN may also offer quotation to offer a similarly designed shaker with the same performance characteristics which will accommodate the fitment on the client’s vibrator motors, junction box and shaker screens and all other replaceable parts.
Further detail is given in Section 11.1 of the Functional Design Specification.
Refurbishment of Degasser
The existing degassers require:
• Sandblast
• Wall thickness inspection
• Painting
• Vac pumps are to be cleaned, wire brushed, repainted
• Vac Pump to be fitted with new motors, see section 7.1, 11.2 of 051-RM-002
• Replacement and Fitment of Vac Pump Motor See section
GN to allow for the above as a lump sum. If any repair is required, this shall be notified to Company and a variation will be raised.
GN may also offer quotation to offer a similarly designed degasser with the same performance characteristics which will accommodate the fitment of the clients degasser pump and all other replaceable parts.

GN scope is to install sensors and cables complete with plugs.http://www.gn-shale-shaker.com/wp-content/uploads/2012/05/double-deck-shaker.jpg
