Tank & Vessel Cleaning Briefing Guide

Briefing Guide: Tank & Vessel Cleaning

Things to consider when deciding to choose remote control high pressure water jetting for tank and vessel cleaning:

  • A good supply of potable water is required (Ideally a fire hydrant – for applications using water pressure up to 1000 bar we are able to use process grade water) 1.5 – 12.0 cubic meters per day.
  • Large and small vessels may be treated using this remote control system. We have cleaned vessels as large as 14m in diameter.
  • Our cleaning heads require an access point at least 150mm diameter
  • A suitable area for laydown of plant (Van and trailer combination or truck options are typically 10m in length)
  • A work platform must be available at the manway if above ground level.
  • Vessels must be electrically isolated.
  • Vessels must be isolated from the process pipework they are connected to.
  • Agitator shafts may be left in-situ.
  • Water jets produce noise – Consider the use of acoustic blankets around each work enclosure to bring noise down to acceptable level
  • Waste water containment, filtration, RGL have our own system for handling this element of the work for you.
  • Waste water disposal: Normally after filtration to remove majority of solids the water is pumped to site drainage or effluent plant. If no effluent plant is available on site then a licenced liquid waste tanker service provider/ disposer will be engaged.
  • Productivity: Generally several times quicker than using conventional techniques. Sometimes water jets offer the only effective method of cleaning thus avoiding the costly replacement of vessels that are heavily contaminated.
  • Removed solids are normally collected in containers placed under the lowest outlet point on the vessel. These are normally moved to disposal point via forklift.
  • Our Plant is diesel driven and as such requires a well-ventilated area in which to operate.
  • Our diesel engine pump units are fitted with spark arrestor and chalwyn valve
  • Our Plant should ideally be positioned adjacent to the work face. It may however be operated remotely over 100m from the work face under special circumstances.
