Introduction
In accordance with regulation B‑2 of the annex to the International Convention for the Control and Management of Ships’ Ballast Water and Sediments, a record is to be kept of each ballast water operation. This includes discharges at sea and to reception facilities.
“Ballast water” means water with its suspended matter taken on board a ship to control trim, list, draught, stability, or stresses of a ship. Management of ballast water shall be in accordance with an approved Ballast Water Management Plan and taking into account guidelines developed by the Organization.
The Ballast Water Record Book entries should be completed taking into account any guidelines to be developed by the Organization.
The volume of ballast water on board should be estimated in cubic metres. It is recognized that the accuracy of estimating volumes of ballast is left to interpretation.
ENTRIES IN THE BALLAST WATER RECORD BOOK
Entries in the Ballast Water Record Book shall be made on each of the following occasions:
(A)When ballast water is taken on board from the aquatic environment (ballasting operation)
.1Start time and location (port of uptake or latitude/longitude)
.2Completion time and location (port of uptake or latitude/longitude and minimum depth of water during uptake)
.3The identity of the tanks affected
.4Estimated volume of uptake and final total quantity retained in cubic metres
.5Whether conducted in accordance with the approved Ballast Water Management Plan
.6Ballast water treatment method
(B)When ballast water is discharged into the aquatic environment (deballasting operation)
.1Start time and location (port of discharge or latitude/longitude)
.2Completion time and location (port of discharge or latitude/longitude and minimum depth of water during discharge)
.3The identity of the tanks affected
.4Estimated volume of discharge and final total quantity retained in cubic metres
.5Whether conducted in accordance with the approved Ballast Water Management Plan
.6Ballast water treatment method
(C)Whenever ballast water is exchanged, treated through internal circulation or treated in tank
1Ballast water exchange
.1Start time and location (latitude/longitude)
.2Completion time and location (latitude/longitude)
.3Minimum distance from the nearest land and minimum depth of water during the exchange or, if applicable, identify the designated exchange area in accordance with regulation B‑4.2
.4Whether conducted in accordance with the Ballast Water Management Plan and state the ballast water exchange method (Sequential or Flow‑through or Dilution) used
.5The identity of the tanks affected
.6Total quantity exchanged and final total quantity on board in cubic metres
.7Treatment method for the incoming ballast water
2Ballast water internal circulation for treatment or in‑tank treatment
.1Start time
.2Completion time
.3The identity of the tanks affected (identifying source and destination tanks if applicable)
.4Total quantity treated (through circulation or in tank) in cubic metres
.5Ballast water treatment method
(D)Uptake or discharge of ballast water from/to a port‑based or reception facility
.1Start time and location of uptake/discharge (state facility name)
.2Completion time
.3Operation carried out (whether uptake or discharge)
.4The identity of the tanks affected
.5Total quantity in cubic metres and final quantity retained on board
.6Whether conducted in accordance with the approved Ballast Water Management Plan
.7Onboard ballast water treatment method
(E)Accidental discharge/ingress or other exceptional uptake or discharge of ballast water
.1Start time and location of ingress/uptake/discharge (port name or latitude/longitude)
.2Completion time
.3Operation carried out (whether ingress, uptake or discharge)
.4The identity of the tanks affected
.5Total quantity of ballast water in cubic metres
.6State the circumstances of ingress, uptake, discharge or loss, the reason thereof, any treatment method used and general remarks
(F)Failures and inoperabilities* of the ballast water management system
.1Time and location (port name or latitude/longitude) of failure of the ballast water management system
.2Operation carried out (state whether uptake or discharge)
.3Description of the issue (e.g. kind of alarm or other description of circumstances)
.4Time and location (port name or latitude/longitude) when the ballast water management system has been made operational
(G)Ballast tank cleaning/flushing, removal and disposal of sediments
.1Time and ship’s location on commencement of ballast tank cleaning/flushing, removal or disposal of sediments (port name or latitude/longitude)
.2Time and ship’s location on completion of ballast tank cleaning/flushing, removal or disposal of sediments (port name or latitude/longitude)
.3Tank(s) identification (name of the ballast tanks as per the Ballast Water Management Plan)
.4Discharge or disposal to a reception facility (state quantity in cubic metres and name of the facility)
.5Disposal or discharge to the aquatic environment as per Ballast Water Management Plan (state quantity in cubic metres, minimum distance from the nearest land in nm and minimum depth of water in metres)
(H)Additional operational procedures and general remarks
 
*Failures and inoperabilities include malfunctions, shutdowns or critical alarms indicating a failure of the ballast water management system which may indicate non‑compliance with the D‑2 standard (except routine information and warnings).
