DESCRIPTION

The offshore skid mounted blender is a fracturing fluid preparation and proppant-proportioning unit which can execute a fracturing pumping design controlling both suction and discharge functions. Unit electronics can be designed to meet Class 1 Div 2 and Zone 2 ATEX specifications, allowing for operation in potentially hazardous areas. The blender unit is equipped with one (1) power unit. The Conventional or Hurricane Style Tub is designed to automatically increase or decrease fluid based on the outgoing demand.

SKIDS

Single or multi skid designs, depending on weight limitations, that are DNV 2.7-1 or ABS certified

POWER UNIT

One (1) Diesel Engine, radiator, fan drive assembly complete with belts, Explosion Proof Air Starter with non-spark engagement. Safety shutdown for low oil pressure, high water temperature, and low coolant level. Engine will also have over speed and over pressure shutdowns.

HYDRAULIC SYSTEM

The hydraulic on the blender powered by a direct drive system via gear box off the power unit. Located on the operator control console will be the following controllers for the following motors: Two (2) sand screws, Three (3) liquid chemical pumps, Two (2) dry additive meters hydraulically driven, One (1) Suction centrifugal pump, and One (1)  Tub.

MIXING SYSTEM

Hurricane Style tub top mounted drive, single Stage Mixer utilized for blending of proppants with fluids, higher control of proppant concentrations and adjustments, and virtually instantaneous change due to low tub size. For Conventional units, an open top blender tub, hydraulically driven mixing paddle, and discharge centrifugal pump will be installed.

SUCTION PUMP

The unit is equipped with one (1) hydraulically driven centrifugal pumps.

SUCTION AND DISCHARGE MANIFOLD

The suction manifold will have ten (10) hose connections. Each connection will have a 4’’ butterfly valve followed by a 4’’ figure 206 union connection (specify thread or wing half). The discharge side of the Hurricane Style Tub will discharge into a manifold with ten (10) hose connections. Each connection will have a 4’’ butterfly valve followed by a 4’’ figure 206 union connection (specify thread or wing half).

LIQUID CHEMICAL ADDITIVE PUMPS

The unit will have three (3) Waukesha U2 018 Pump rated up to 15 gpm each. Additional pumps can be installed. Each pump can be controlled in manual or automatic mode and will each have coriolis flow meters with digital rate readouts.

DRY ADDITIVE METER

Two (2) dry additive systems will be installed. Magnetic pick-up will be used for product delivery analysis. The dry additive meters can be controlled in manual or automatic mode.

SAND SCREWS

The unit will be equipped with two (2) 12” sand screw. Sand screw is sized based on your desired sand concentration requirements. This unit is capable of controlling and monitoring sand delivery with the electronic system.

THE FIP SMART OP-ACQ SYSTEM BLENDER AND AUTOMATION CONTROLS

  • Unit can be controlled locally or remotely in the control room.
  • Unit will have the ability to monitor sand, liquid additive pumps, dry additive
    pumps, down hole density, suction and discharge volume. This system
    is also designed to automatically or manually adjust and maintain preset set
    points of sand concentration, liquid additive concentration, and dry additive
    concentration.
  • Touch Screen Color Monitors will allow the operator the ability to operate the
    unit in manual or automatic mode
  • Displays real time operating parameters, including Sand concentration, Liquid
    Additive Concentration, Dry Additive Concentration, Centrifugal &
    Tub Parameters, and more.
  • Current stage and total job volume totals including Suction Rate, Discharge
    rate, Liquid additives, Dry additives, and Sand control.
  • Sand screws, dry additives, and liquid additive pumps can be slaved to
    blender clean rate or simulated rate.
  • Job data and job parameters are transmitted for data acquisition and trending
    purposes to the control room.
  • Job Design has the ability to store up to 50 jobs with up to 100 stages.
