1. Introduction

Scanjet model SC 40RT is a tank cleaning

machine especially developed for cleaning

of cargo and slop tanks onboard chemical/

product carriers. The size, construction and

cleaning requirements of these tanks are

design criteria, which have been evaluated

prior to installation in your application.

SC 40RT tank cleaning machine consists

of two main parts; a gun unit that is ﬁxed

installed on the tank and a turbine driven

drive unit. The cleaning procedure will start

by opening the valve for cleaning media.

The drive unit will now rotate the bottom

housing, also forcing the nozzle housing

to rotate around its own axis because of

the gear system. This creates a criss-cross

cleaning pattern on the tank walls. When

the cleaning procedure is ﬁnalized the

valve is to be closed.

This manual has been prepared as a guide

for persons who will be operating and

maintaining the tank cleaning machine.

The key for long tank cleaning machine

life will always be carefully planned

maintenance, the tank cleaning machine

is actually doing a rough and dirty job for

you. With proper maintenance the Scanjet

SC 40RT will keep servicing you for many

years.

2. Safety Instructions

• If the machine is used in potentially explosive atmospheres then tapes or

joint sealing compounds, which are electrical insulators, must not be used

on threads or joints, unless an electrical connection is otherwise established

to ensure an effective grounding. In addition, connection pipe work must be

electrically conductive and grounded to the tank structure. The resistance

between the nozzle and the tank structure should not exceed 20 000

Ohm. This is important in order to avoid any build up of static electricity

in the machine. For further information see CENELEC R044-001 Safety of

Machinery, guidance and recommendations for the avoidance of hazards

due to static electricity.

• When the equipment is operating in potentially explosive atmospheres,

measures have to be taken to verify that the tank is inert at all times during

cleaning operation. This is to avoid sparks and possible explosions since ﬂuids

moving at high velocities through air causes electrostatic build up in the

media. As an extra precaution the cleaning media could be made conductive.

• The machine should be installed in accordance with national regulations for

safety and other relevant regulations and standards.

• Precautions should be made to prevent starting of the tank cleaning

operation, while personnel are inside the tank or otherwise can be hit by

jets from the nozzle.

• In EU-countries the complete system have to comply with EU-machine

directive and should be CE-marked. In North America consult Underwriters

Laboratory for any speciﬁc regulatory needs relative to the entire CIP (Clean

In Place) System.

• Earmuffs should always be used when operating machine.

• Safety goggles should be used when opening cofferdam plug.

• Be careful not to drop tank cleaning machine/equipment when lifting and

carrying. Dropping the machine could cause serious injuries. Never stand

under the machine during mounting.

• When handling the tank cleaning machine, never lift machine by the nozzle.

• The equipment may only be used for tank cleaning operations as described

in this manual.

• The equipment has not been assessed as a safety related device as referred

to in directive 94/9EC Annex II, clause 1.5

Always follow these instructions before taking the SC 40RT into service!

3. General Description

Cleaning media comes from the supply line and enter through the inlet housing,

passing over a turbine which drives the drive unit via a magnetic coupling,

continue through the main pipe to the nozzle and then out in the tank.

The drive unit will rotate a shaft inside the machine, the

turning shaft. The turning shaft is connected to the bottom

housing that rotates the nozzles via a gear system. The

nozzles will hereby clean the tank in a criss-cross pattern.

The rotation speed is controlled by the rotation speed of

the turbine and could easily be set to desired speed, see

“7.7. Speed Adjustment” on page 20.

The rotations of the nozzles are indicated on the top nut

visible through the cofferdam or on the top shaft on top

of the drive unit.

The rotating nozzles will create a cleaning pattern as per

below on the vertical tank-walls. After one cycle a cleaning

pattern will be created as per ﬁg 1. After four cycles the

pattern will be completed as per ﬁg 2. After this the

pattern will be repeated.

A full pattern is created when the main body has rotated 47 turns. With a

rotation speed of 2 rpm will a full pattern take approx. 23,5 min. Note that the

time is depending on the actual setting of the turbine and water pressure. One

cycle will take about 6 minutes.

Cleaning of tanks is a process depending on a number of factors; the soilage of

the tank, distance to tank walls, cleaning procedure and cleaning agent. All these

factors are deciding for the number of cycles that needs to be run.
