5.
Preparation for installation of remote control panel from the Ballast Water Treatment System.
6.
Verification of dimensions engine room and pump room skylights.
7.
Verification of re-design for forepeak ballast piping.
1. Preparation for 3D scanning and location of same onboard All compartments of the pump room have been inspected with relation to the installation of the Ballast Water Treatment System. The original plan was to re-locate the N2 tank. The N2 tank is presently located on the 3rd deck level and should be shifted to the 2nd deck level in order to make space for the filter unit of the Ballast Water Treatment System. A further inspection was conducted on “inner bottom level” in the pump room. Both the Port- and Starboard side of the inner bottom level have a free space available of about 2500 x 2500 mm with sufficient height for maintenance work on the filter unit.
2. Verification of re-locating of N2 tank located in pump room The N2 tank is presently located at the 3rd deck level on Portside. The original plan was to shift the N2 tank to the 2nd deck level and to install the filter unit of the Ballast Water Treatment System on the 3rd deck level. The clear deck height between stiffeners of the 3rd deck level is abt. 3700 mm. The clear deck height between stiffeners of the 2nd deck level is abt. 2950 mm. Dimensions are measured between floor platings.
Fig 1. Dimensions of N2 tank
ii
As can be seen in Fig. 1 the total height of the N2 tank is 2515 mm, excluding the valve fitted on top of the pressure vessel. As mentioned above, the height of the 2nd deck level is about 2950 mm. At the original re-location position on the 2nd deck level a ventilator system is installed comprising of a fixed fan and exhaust duct.

3. Preparation for electrical connection of the Ballast Water Treatment System During the inspection the main switchboard was checked for suitability of connection for the Ballast Water Treatment System. At present there are five spare breakers available of which two on the No. 1 440V feeder panel and three on the No. 2 440 V feeder panel with a maximum capacity of only 30A.
4. Preparation for installation of the source- and control panel Both the source- and the control panel require installation in the engine room. The distance between the source panel and the UV reactor must not exceed 30 meter. A location for both panels has been found on the 3rd deck level in the engine room iwo the lub oil and fresh water coolers.
Fig 4. Location of source- and control panels At this location sufficient cable trays are available to use and guide the power cable from the control room to the source panel.
iv
5. Preparation for installation of the remote control panel from the Ballast Water Treatment System The cargo control room has been inspected in order to verify a location for installation of the remote control panel for the Ballast Water Treatment System. Sufficient free space is available adjacent to the wall panels that include the rest of the remote control panels from various other equipment. Furthermore, both the wall and the ceiling panels can be easily removed for the installation of the remote control panel wiring system. The cargo control room is located adjacent to the duct and electric space on the Boat deck. Pre-installed cable trays are available for the required wiring.
Fig 5. Suggested installation location of remote control panel in cargo control room
6. Verification of dimensions engine room and ballast room skylights Both the engine room and the pump room skylights have been measured for suitability of lowering down the necessary Ballast Water Treatment equipment. Dimensions engine room skylight: Abt. 910 x 1610 mm free space Dimensions pump room skylight: Abt. 940 x 1230 mm free space
v
Both the source- and the control panel will need to be lowered down in the engine room. No modifications will have to be made to the engine room skylight. Lowering down of the filter unit from the Ballast Water Treatment System can not be conducted via the pump room skylight due to oversized dimensions. Furthermore, all other deck openings on the different deck levels have similar dimensions. The filter unit must enter the pump room via the ships side.
7. Verification of amendment for forepeak ballast piping The present ballast piping design is as such that the forepeak tank is serviced by the fire and general service pump. This pump is located in the engine room and has a separate overboard line located on the Portside of the vessel. All other ballast tanks are serviced by the ballast pump which is located in the pump room and the electromotor that drives the pump is located in the engine room. A separate overboard line is located in the pump room on the Portside of the vessel. At the present configuration the owners would require one Ballast Water Treatment System for the forepeak tank and one Ballast Water Treatment System for the remaining ballast water tanks. Miura asked if the forepeak tank piping could be connected to the existing ballast piping system that is presently serviced by the ballast pump located in the pump room. I was not able to trace the forepeak ballast line as the gratings in the pump room were still fixed to the structure. I do however not see any problems to connect same to the ballast pump system.
Conclusions 1.
The original installation location of the filter unit (at present location of the N2 tank) must be reconsidered. Re-locating the N2 tank and removing the fixed ventilator system on the 2nd deck level is a lot of work and certain height restrictions have to be taken in account on this 2nd deck level.
2.
A location has been found for the filter unit. This can be either placed on the Portside or Starboardside on the lower floor deck of the pump room.
vi
Fig 6. New proposed location of filter unit on lower floor deck pump room 3.
Both the source- and the control panel can be installed in the engine room iwo the lub oil and fresh water cooler located on the 3rd deck. Cable trays are close by and can be used.
4.
The remote control panel can be easily installed in the cargo control room. Sufficient space is available and the cargo control room is conveniently located opposite the cable duct trunk. Cable trays are running from the cable duct trunk to the cargo control room.
5.
Five spare breakers are available in total on the main feeder panels no 1 and 2. The capacity is however not sufficient so a breaker with more capacity will need to be installed.
Work to be carried out during 3d Scan The following areas will need to be scanned: −
Pump room. Lower floor level, 3rd deck and second deck levels.
−
Engine room. 3rd deck level iwo the lub oil and fresh water coolers in order to verify if the sourceand control panel actually fit.
The following will need to be verified by AL and LH −
Check clear height of the proposed filter unit installation areas.
−
Check connections for working air and fresh water in the pump room. If they are iwo of a deck that is not scanned by 3d we might consider to scan that deck as well.
vii
−
Re-check and re-measure the proposed location for installation of the source and control panel.
−
Open up main feeder panels no 1 and 2 in control room and make pictures of the breakers presently available for spare.
−
Locate the forepeak ballast line in pump room and make sure this is scanned as well.
−
To verify if the source- and control panel can be transported between the 2nd deck and 3rd deck level in the engine room.
−
To make copies / pictures of the general arrangement plan (all plans located in the ship’s office on Capt. deck)
A full set of pictures of the vessel and ship’s documents will be send over to you. Matthijs Post
