a) what are the salient features of ballast water management
b) how would you as chief engineer with consultation with the master of the vessel implement plan prior to your vessel arriving at an USA port / Australian port
Ans.
It applies to ships of 400 GT and above
Regulation B-1(ballast water management plan)
" every ship shall have onboard and implement a ballast water management plan specific to the ship and approved by the administration
" It includes detailed description of the actions to be taken to implement the requirements, designated officer in charge, contain reporting requirements, detail procedures for disposal of sediments at sea and shore etc
Regulation B-2 (Ballast water record book)
Regulation B-2 (Ballast water record book)
" every ship shall have an ballast water record book
" the record book entries to be maintained on board for 2 years and thereafter in the
company control for 3 years
company control for 3 years
" it should record when ballast water is taken onboard, circulated, or treated for ballast
water management purposes and discharged into sea
water management purposes and discharged into sea
" it should also record when ballast water is discharged to a reception facility and
accidental or exceptional discharges into the sea
accidental or exceptional discharges into the sea
" all entries in the record book should be signed by officer in-charge and each completed
page by master
Regulation B-4 – (ballast water exchange)
page by master
Regulation B-4 – (ballast water exchange)
" All ships conducting ballast water exchange at least 200 nautical miles from nearest land and water at least 200 m depth
" If ship unable to conduct exchange as above should be as far as nearest land and in all cases at least 50 nautical miles from the nearest land and 200 m depth
Regulation D-1 ballast water exchange method
" 95% efficiency volumetric exchange
" If pumping through method – 3 times the volume of each tank
Regulation D-2 – ballast water performance standard
(i) To avoid intake of harmful organisms, where practicable avoided in areas such as
area notified by port state in darkness, when bottom dwelling organisms rise to the upper layer
in very shallow water where propeller may stirrup sediment
(ii) To removal of sediments from tank time to time
" Ballast tanks to be cleaned(dry dock)
" Accordance with ballast water management plan
(iii) Avoidingunnecessaryuptakeanddischargeofballastwater
(iv) Avoid ballast water exchange in critical weather or any circumstances where safety of
life is threatened
(v) Nomination of key ship board personnel for operations
(vi) Ship officers and rating should be trained
(vii) Ship’s pumping plan and ballast pumping arrangements, position of air and sounding
pipes, all compartments and tank suction with the pipe lines connecting them to the ship’s ballast pump and in case of flow through method, the opening at the top of the tank for release of water together with the overboard discharge arrangement
(viii) The method to ensure sounding pipes are clear and that air pipes and non-return devices are not in good order

Before U.S. Port
1. prior arrival 24 hours before, ballast water tank log to be sent and a declaration that
ballast water exchange has been completed 200 N-m away from base line
ballast water exchange has been completed 200 N-m away from base line
2. Ballast pump supply to be put off of electrical driven
3. ballast lines to be shut and sealed
In Australian ports
1. Same as above
Additionally
2. seal numbers to be mentioned in ballast water exchange declaration sheet
1. Same as above
Additionally
2. seal numbers to be mentioned in ballast water exchange declaration sheet
