3. MECHANICAL INSTALLATION
This section contains information relevant for planning the installation of mechanical
components and connections to water and instrument air.

3.1 GENERAL REQUIREMENTS

 
The overall layout is defined by the Flow chart drawing and details for components are
stated on the dimension drawings.

Installation prerequisites:

Installation area Machinery

space on the
vessel, for
example
engine room
or pump room
Ambient air temperature: 0 – 50 °C

Relative humidity: ≤ 100 %

 

3.1.2 WELDING REQUIREMENTS

 
Earth connection must be done according to the below. If not, the equipment can be
seriously damaged:

• Earth connection must be made before any welding is done.

• Electrical welding: Connect the welding unit’s negative lead (work lead) to

the component you will weld close to the welding area.

• Follow local regulations for electrical installation and earthing (grounding).

• Installation must be done by a fully trained professional installer.

3.2 GENERAL ARRANGEMENT

General arrangement of PureBallast components are provided in Figures 1

3.3 CABINET
 
This section covers installation guidelines for cabinets, regarding mechanical installation. For
electrical installation, see section Electrical design.

• Cabinet must be installed so that there is free space available to open the door.

• The cabinet must be placed on a firm level surface and fixated. The legs

of the component can be bolted or welded in place on a steady foundation.

The cabinet shall also be attached to the bulkhead using the attachments

on the cabinet backside. The cabinets are fixed to the ships structure via

vibration dampers to minimize the effect of vibrations from the hull affecting

components inside the cabinet.

• To prolong the lifetime of the cabinet, we recommend to install it in the

coolest possible area in the range of 0 to 50º C.

The Cabinet installation drawings are provided in Figures 2 or drw ТР.941.102.001

4. PIPE DESIGN
 
This section contains information relevant for P&ID. 

4.1 BALLAST SYSTEM

Ballast systems are designed to receive water ballast in the tanks, pump it and remove
it from the vessel in order to change the draught and stability of the vessel (ballast system),
align or create an artificial roll (roll system) and differential (differential system) in case of
loading and unloading operations, swimming in ice and in emergency situations, as well as in
connection with the consumption of fuel and water reserves. The Pure-Ballast 3.2 135
Compact ballast water treatment plant in the area of (-2)-(-1) fr is connected to the existing
pipeline by means of additional pipes. The installed pipelines are used to connect the BWTS
equipment to each other and connect the BWTS to the ship's ballast system.

Connection of the installation and additional pipelines to the existing ship's ballast pipeline is
shown drawing TP.941.400.005 "Ballast system re-fitting".

This section contains information relevant for planning the electrical

installation and routing.

5.1 ELECTRIC LOAD ANALISIS

Since the new BWTS equipment was installed, an addition was made to the calculation of
the Electric load analysis. The calculation showed the sufficiency of the existing ship power
plant to power the newly installed BWTS equipment.

The calculation is presented in drw. ТР.941.600.001

5.2 BALLAST WATER TREATMENT STAITION

The system is supplied complete with a power/control and alarm cabinet (EC).

The EC cabinet is used to connect BWTS equipment in Skid unit: UV reactor, pump, sensors,
etc. Also, from EC connecting to GPS system, and to alarm system.

The EC are connected to the power supply network from the main switch-board by using
spare circuit breaker.
