OIL RECORD BOOK

A book or log kept by the Master or Chief Engineer wherein every discharge or escape of oil is recorded.
Every nontanker of 400 GRT and above, and every tanker of 150 GRT and above must have ORB part I ( Machinery space Operation ). All tankers of 150 GRT and above must have ORB part II ( Cargo/Ballast operation )

The ORB must be preserved for 3 years after last entry has been made. The ORB must be completed on each occasion, on tanks to tank basis if appropriate, Entries must be fully recorded without delay and each completed entries must be sign by the officer in charge of the operations concerned. Each completed page must be sign by the Master.

Entries include- any movement of oil in to ship, within ship and out of ship.

  • Ballasting or cleaning of fuel oil tanks
  • Discharging of dirty Ballast or clean water from fuel oil tanks
  • Collection and disposal of oil residue (sludge)
  • Non-automatic discharge over board or disposal otherwise of bilge water which has accumulate in machinery space.
  • Automatic discharge over board or disposal otherwise of bilge water which has accumulate in machinery space.
  • Condition of oil discharge monitoring and control system.
  • Accidental or other exceptional discharge.
  • Bunkering fuel or bulk in lubricating oil.
  • Additional operational procedure or general remarks.

  • Loading of oil cargo
  • unloading of oil cargo
  • Internal transfer of oil during the voyage
  • Crude oil washing ( COW tankers only)
  • Cleaning of cargo tanks
  • Ballasting of cargo tanks.
  • Discharging Dirty ballast.
  • Discharging of Clean ballast contained in the Cargo tanks
  • Ballasting of dedicated clean ballast tank. ( CBT tankers only)
  • Discharging of ballast from clean ballast tank. (CBT tankers only)
  • Discharge of water from slop tanks in to sea.
  • Disposal of residual and oily mixtures no otherwise required

  • Accidental or other exceptional discharge.
  • Additional operational procedure or general remarks.

For vessel engaged in specific trade

  • Loading of ballast water.
  • Re-allocation of ballast water within the ship
  • Ballast water discharged to reception facility.

REGULATIONS GOVERNING DISCHARGE OF OIL.

Machinery space:

  • The ship not within a special area.
  • The ship is proceeding enroute
  • The oil content of the effluent without dilution does no exceed 15 ppm.
  • The ship has in operational:
  • 400 to 10,000GRT -an oil filtering equipment.
  • Above 10,000 GRT - an oil filtering equipment and with arrangement for alarm and automatic stopping any discharge of oily mixture when the oil content of effluent exceed 15ppm.

Tankers:

  • The tankers is proceeding on a voyage
  • The tanker is not within a special area.
  • The tanker is more than 50 miles from nearest land
  • The instantaneous rate of discharge of oil content is not more then 30 litres per nautical mile.
  • The total quantity of discharge is not greater then 1/30,000 of the total quantity of the particular cargo of which the residue formed a part, or in case of existing tankers (before 1980), the total quantity of discharge is not greater then 1/15,000 of the total quantity of the particular cargo of which the residue formed a part
  • The tanker has in operation an oil discharge monitoring and control system and slop tank arrangement. (Clean ballast and processed bilge water (Max 15 ppm) can be discharged within a special area)
