Tank Cleaning Service
The TCU (view
The Soil Recovery A/S tank
cleaning unit (TCU) is developed to meet the HSE requirements on
minimizing the entry on confined spaces as well as reduced waste
generation on board mobile drilling rigs, platforms and supply vessel.
In addition to this the TCU reduces manpower as well as down time during
The TCU is developed to meet
offshore and onshore applications.
The TCU contains all necessary
equipment to perform the tank cleaning job:
Portable and automatic tank cleaning
High pressure pump and hose reel for fresh wash
Mud cleaning dosage system
Portable submersible pump
High pressure water gun cleaning unit (hot water
unit optional on land based units)
Hydraulic power pack for submersible pump and
Air compressor for RPE
Power generator (optional)
Hand tools, Personal Protection Equipment (PPE)
Storage tank for fresh or recycled wash water
The portable and automatic
cleaning machine is arranged on a flexible hose with embedded wires for
electrostatic deviation to earth. Fresh or recycled wash water is used
as cleaning fluid, and is pumped from the storage tank (and/or
connection to city water) to the rotary jet head of the cleaning
machine. The flow of the cleaning fluid makes the nozzles perform a
geared rotation around the vertical and horizontal axis. In the first
cycle, the nozzles lay out a coarse pattern on the tank surface. The
following cycles make the pattern gradually denser until a full pattern
is reached after 4 cycles.
The cleaning time to reach a
full pattern varies from 10 – 20 minutes depending on the inlet pressure
and the size of the nozzles being used.
The offloading pump on the
vessel/rig is used to offload the tank during the cleaning process.
The portable submersible pump is
a vertical screw pump which is able to pump a wide range of fluids from
water to extremely viscous oil even with some trash content. Recycling
of wash water is possible if the size of the particles do not exceed 2-3
mm. The offloading pump or the submersible pump is then used to pump the
water through the cleaning machine.
By deploying the TCU the
cleaning of mud tanks to brine standard will reduce the entry on
confined space by 50 to 75 % and reduce the down time by 30 to 40 %.
