Anchor Boss

Maximize diver bottom time.

Suction anchor pump for the installation and removing of suction anchor / suction piles. Real time flow and pressure readings with data logging. Available through Ashtead Technologies.

Anchor Pump Features:

  • This suction anchor pump is physically larger than some other pumps. This is a result of a deliberate decision to create the highest possible water flow with the least restrictive flow paths with high capacity suction and relief valves to match very high water flow rates.
  • Highly efficient pump with superior flow-rate using best practice principles of unrestricted water flow path to reduce insertion/extraction times and optimize site efficiency.
  • Erosion resistant impeller and housing.
  • Filtered suction into pump.
  • Data feedback redundancy via Perry UCD and topside laptop.
  • Task specific water flow meter integrated into pump unit to accurately measure water flow in both directions of flow.
  • Hard faces sealing arrangement and erosion resistant pump materials are resistant to high levels of sediment entrainment in product stream, improving reliability.
  • Suction and discharge entries screened for pump safety.
  • Pump valve-set has discharge hose connection to direct extracted pump flow away from work area to enhance visibility by reducing work area turbidity.
  • High flow suction and pressure relief valve module to ensure maximum safety from exceeding pd max. on caisson.
  • Real time Perry UCD Subsea display showing caisson pressure differential and water pump flow along with data logging topside laptop to allow clear picture of anchor installation/removal scheduling.
  • Flexibility of mounting. Vortex Anchor Boss can be mounted inside or outside the ROV frame with the supplied frame or in modular form inside the ROV.
  • Pump graph data gathered under real world conditions in pressure vessel blown down to 10bar (340ftsw)

Why is Vortex Dredge Superior to other ROV Units?

Vortex dredges have been designed to combine high suction values and high water volumes to tear up sticky soils with very high suction then keep it flowing with high water volume. Powerful, simple, effective.

Example: Getting a "RIDICULOUSLY THICK MILKSHAKE" ® ™ to move through a straw is similar to dredging a very sticky seabed and suction is key because if you drive a suction hose deep into sticky mud the water flow in the suction hose will often stall and the hose is essentially filled with a 'plug' of mud and only high suction will clear the hose. Once the hose is clear then water flow takes over. Suction does the work and water flow continues the work done.

VORTEX performance figures DO NOT have a small print clause with an Asterix symbol next to figures which would represent "best case Scenario" removal rates as opposed to actual removal rates.

VORTEX removal rates are ACTUAL removal rates as seen with actual material moved using Magnetite black iron sand and rocks weighing 2.375kg per liter as to the sample product.
