OptiMar Ballast Systems
Komplett system per pumpe.Installasjon er ikke inkludert
I confirm that to date we have not had any down time and it is being used for all ballast operations on and off the vessel.
Lars Nordin, VP Technical Services
Videreutvikling og forsøk for Å bedre separasjonsgrad.
Utvikling ny type UV Fra 3,6 Kw til 58 Kw pr. enhet.
Bruk av medium trykkslamper med flere lamper i hvert kammer.
UV dose på 147 Mws/cm2 ved 3000 M3/t ved 90% transmissjon.
Bruk av filter i tillegg til Seperator

Before Pumps # 1 Pump Is Started the Following Valves Have to Be in Open Position:
AZ043VF- AZ045VF, AZ052VD, And/or AZ055VD, GV/CK 1 (Manual, Normal Open- NO.) And Manual Sea Outlet AZ042VD.
BFV 1, By-pass Valve Should Be Always in NC (Normally Closed) Position.
BFV 2, Inlet Valve to Separator Should Be Always in NO Position.
BFV 3, X-over Valve Should Be Always in CLOSES Position During Ballasting, and OPEN During deballasting.
BFV 4, Outlet Valve From UV Should Be Always in NO Position.
The Discharge Valve AZ 042VD Should Be Kept CLOSED When the OptiMar Ballast Systems Are Used During Discharging
CV/CK 1 Is an Automatic Backpressure Valve With a Stop-check Feature, Which Will Be Closed Until a Preset Pilot Pressure Is Reached. Set at 1,2 Bar.
The Pilot Valve Will Control the Set Pressure.
The Control System Can Be Override by Closing the 2 Small Ball Valves on the Pilot Line. A Pin on Top of the Valves Will Show the Position of the Globe.
Water Will Gravitate Into the Ballast and Treatment System and Pressurize/displace Air Out of the UV, MicroKill Separator and Pipelines Through the Air Vent Valve AV 1. The Valve Is Manually Operated.
When the System Is Full of Water It Is Not Necessary to Release Air.
A Small Manual Valve Is Placed on the Outlet Pipe From the UV and Can Also Be Used for Air Release.
Normally This Is Only Needed When the Treatment System Has Not Been Used for Some Time and Has Been Drained.
The Control Valve Will Shut Once the Pressure Is Below the Set Pressure and the Valve AZ045VF Is Closed.
Start MicroKill UV When the UV Chamber and Pipeline Are Filled up.
See Separate Procedure for Starting the UV.
Needs About 3 Minutes to Warm up Lamps..
Start Pump # 1.
Water Will Be Drawn From the Sea Water X-over, Through the Strainer (Not Shown) and Pressurized Through the T-ee, BFV2 (NO), Flow Meter M1, and Into the Separator Inlet.
In the MicroKill Sep the water will be separated into two streams; the particles will flow along the wall of the separator and into the sludge chamber and further out through the DN 50-drain line.
The pressure in the sea discharge line is the draft of the vessel, which is maximum 8,2 m. 8,2 m WC or 0,82 bar. The backpressure valve will maintain a pressure that is higher than the inlet pressure and will push the water out the discharge. This can be read on the M2.
The clean water is drawn to the vortex of the separation chamber and outs through the outlet pipe in the bottom and further into the UV chamber.
The clean part of the water will come out at the bottom outlet (DN 200) and into the UV Chamber
The sludge water will be piped to the sea outlet through a flow meter (M2), a Stop/check valve, CKV2, on the downstream side of the BFV 3 valve.
The clean water will pass through the MicroKill UV, which has 12 UV lamps. During the passage the water will be ultraviolet irradiated and bacteria and aquatic organisms inactivated.
From the outlet of the UV chamber the UV treated water will pass CV/CK1, which maintains a preset backflow pressure, the manifold and valve AZ055VD/ AZ052VD, into the ring mains and further into the ballast main line.
Open valve, BFV3, manually. Close valve CV/CK 1.
Open all valves for normal ballasting.
DO NOT OPEN AZ044VD.
Check for air in the separator and UV.
Start MicroKill UV. Needs about 3 minutes to warm up lamps
Start Pump # 1
CV/CK1 will gradually open as pressure builds up to preset pressure
Water will be drawn from the Main Ballast line and pumped through the AZ 045VD, MANIFOLD, M1, the MicroKill UV, CV/CK1, BFV3, & AZ042VD to the sea
FOR REPLACEMENT OF QUARTS SLEEVES etc.
a) Close BF2 & BF4.
B) Open small drain valve underneath the UV
C) Open Air release valve AV1 to let air into the separator.
TO COMPLETELY EMPTY THE SYSTEM.
A) Close AZ045VD and BF3.
B) Open all other valves
C) Put in 1,2 bar max. airpressure on vent valve.
D) All water will be drained out through the drain pipe and overboard.
E) Release air out of the system.
There are 3 sampling points, S1 - S2- S3.
Samplings should be taken at the same time from all 3 points.
For microbiological tests sampling points and bottles must be sterilized. At least 3 samples must be taken within a few minutes to get a good average sample.
For particle tests only clean bottles are required .
Total No. of tanks to be discharged inside the United States EEZ or into an approved reception facility.
Of tanks to be discharged, how many Underwent Exchange:
Of tanks to be discharged, how many Underwent Alternative Management:
Please specify alternative method(s) used, if any: Specifically, describe methods (other than exchange) used for ballast management.
If no ballast treatment conducted, state reason why not: This applies to all tanks and holds being discharged into waters of the United States or into an approved reception facility.
Ballast Management Plan on board?: Is there a written document on board, specific to your vessel, describing the procedure for ballast management? This should include safety and exchange procedures (usually provided by vessel’s owner or operator). Check Yes or No.
Started pump #1 and pumped water sea-sea in the port of Mazatlan. The port water was brownish in color. The Port of Mazatlan is a narrow channel, about 350-m wide with a dept of 11 m. The vessels draft was about 8 m.
There are a number of fish receiving and manufacturing plants inn the inner harbour. We assume that the washing and process water from the plants are dropped into the harbour.
Samples were taken at 13:00 hrs. and a turbidity of 6,61 FTU was measured on separator inlet. Outlet from the UV was 6,48 and outlet drain 8,61.
Samples were taken in 3 transparent plastic bottles from each sampling outlet and a 4th bottle with potable water from tap as reference. The seawater samples were slightly brownish compared to the reference water.
No visible particles, which means that the size must be less than 20-30 microns.
New samples were taken at 18:00 hrs when the vessel departed from the berth and was agitating mud etc. from the harbour bed with the side trusters and main propellers.
Inlet turbidity was; 7,04 FTU, after UV/separator; 5,26 and in the drain; 7,41.
The 25% reduction in turbidity must be due to larger particles has been agitated from the harbour bottom by the propellers. This was also the intention of the test. After 2 days there were settlement of particles on the bottom of the bottles.
A particle analyze of the samples will confirm the assumption.
