The International Merchant Marine Registry of Belize

  • IMMARBE first opened its doors in 1991 to offer Flag State services to the international shipping community
  • All legislative measures, Statutory Instruments, amendments, schedules, ratification of conventions, are channeled through the Registrar of Ships, under the Minister of Finance.
  • Implementation of International Maritime Conventions.
overview continued
Overview (continued)
  • Through a network of Deputy Registrars/Designated major maritime centers provides services to ship owners/operators and seafarers.
  • There are currently 63 designated offices worldwide supported by 204 General Safety Inspectors(GSI), who conduct inspections to verify compliance with international instruments and national legislation.

The Belize-registered fleet

- 954 vessels:

  • 510 cargo & passenger ships
  • 136 fishing vessels
  • 98 yachts
  • 210 miscellaneous types, non-Convention

Management And Reporting On Board Ships Of ODs Controlled Under The Montreal Protocol On Substances That Deplete The Ozone Layer

ods used aboard ships
ODS used aboard ships

The main uses are as refrigerants on board ships, for refrigeration/freezers of cargo (in holds and containers) and provisions; in air conditioners and in fire-extinguishing systems. The most common are:

  • HFCs (hydrofluorocarbons)
  • CFCs (chlorofluorocarbons)
  • HCFC-22 (which is also a CFC)
  • Halons
ods used aboard ships continued
ODS used aboard ships (continued)
  • Halon 1211 Bromochlorodifluoromethane
  • Halon 1301 Bromotrifluoromethane
  • Halon 2402 1, 2-Dibromo -1, 1, 2, 2-tetraflouroethane (also known as Halon 114B2)
  • CFC-11 Trichlorofluoromethane
  • CFC-12 Dichlorodifluoromethane
  • CFC-113 1, 1, 2 – Trichloro – 1, 2, 2 – trifluoroethane
ods used aboard ships continued1
ODS used aboard ships (continued)
  • CFC-114 1, 2 – Dichloro –1, 1, 2, 2 – tetrafluoroethane
  • CFC-115 Chloropentafluoroethane

* HCFCs, CFCs and Halons have not only strong ozone-depleting potential but also , including HFCs have significant potential to cause global warming.

international and national maritime regulations
International and National Maritime Regulations
  • Chapter II of the International Convention for the Safety of Life at Sea (SOLAS). Vessels of 500 gt.
  • Annex VI of the International Convention for the Prevention of Pollution from Ships (MARPOL 73/78). Vessels of 400 gt
  • IMMARBE’s Merchant Shipping Notices (MSNs). All ships
  • Others: EU and USA Regulations.
solas convention
SOLAS Convention
  • 1992 Amendments prohibit new installations of Halon Fire Extinguishing Systems since 1994
  • 2000 Amendments prohibit new installations of Fire Extinguishing Systems containing Halon 1211, 1301 and 2402 on ships built on or after 1st July 2002.
marpol 73 78
MARPOL 73/78
  • The use of CFCs with a high ODP prohibited in refrigeration and A/C systems as of November 1992.
  • The use of Halons prohibited on ships built after July 1992 unless for essential (lifesaving) use. Full scale tests prohibited from January 1992.
  • The addition of chemical waste to bunkers prohibited from January 1992.
marpol 73 78 cont d
MARPOL 73/78 (cont’d)
  • Annex VI entered into force May 2005 and prohibited new installations of FFE and PFE units using ODS on all ships.
  • Revised Annex VI (2008 amendments) entered into force on 1st July 2010.
  • Reg. 12 prohibits new installations of refrigeration, A/C and FE systems using ODS other than HCFCs on ships build on/after 19 May 2005 and with HCFCs on/after 1st January 2020 (70-80% uses HCFC-22).
marpol 73 78 cont d1
MARPOL 73/78 (cont’d)
  • Reg.12.6 requires that ships which have rechargeable systems that contain ODS maintain an ODS Record Book.
  • Reg.12.7 requires that entries are made in respect of ODS when specific actions are carried out.
  • This Reg. does not apply to permanently sealed installations with no charging or potentially removable components containing ODS.
immarbe s msns
  • MSN-06-19 on reporting CFCs and phasing out Halons on board Belize-registered ships.
  • MSN-10-39 on implementation of the Revised Annex VI of MARPOL.
  • Draft MSN-11-40 on creating an expanded database of ships with installations containing ODS.
msn 06 19
  • Establish an accelerated phase-out date (1st January 2010) of Halons
  • Prohibits deliberate discharges including “live tests”
  • Introduces reporting and recording requirements (CFCs and Halons)
  • Adopts servicing requirements (annual leakage tests for FFE systems.
  • Requires disposal in approved Banking and Reception Facilities.
msn 10 38
  • Creates a database of Belize vessels with systems containing HCFCs and introduces adopted amendments to the Supplement to the IAPPC: System details, location o/b and type of HCFC.
  • Implements an ODS Record Book and requires that entries are made in respect of ODS mass (kg): supply, charge & discharge of system, repair & maintenance.
  • RO, PSC and GSI guidelines



  • additional workload for technical staff
  • incomplete data reporting
  • low RO compliance,
  • Convention cut-off size (400 and 500 gt)
  • fishing vessels
  • ‘Flag-hopping”,
  • apparent lack of readily available reasonable BRF
  • world economic situation
  • high cost of systems replacements or short service life.



  • additional workload of Technical staff
  • additional interim personnel ($)
  • incomplete reporting of data (no HCFC type)
  • lack of standardized ODS Record Book
  • Convention cut-off size
  • fishing vessels,
  • difficulties ascertaining supply of HCFCs to ships in certain Asian countries (illegal trade?).


  • 182 ships identified as having RF, A/C and FFE systems containing Halons and CFCs
  • 66 vessels granted extensions or issued with Statement of Fact (next D/D, laid up due to economic situation, scrapping, near end of service life, etc)
  • 32 vessels to 100% phase out of Halons and CFCs.


  • 225 ships identified as being fitted with system containing HCFCs
  • Mostly HCFC-22 (R-22)
  • Data on use of non-ODS refrigerants (R-404A).
  • World fleet data estimates 315% increase of HFC due to substitution of CFC and HCFCs
draft msn 11 40 may consider
Draft MSN-11-40 may consider:
  • Increases data reporting standards: adds system’s HCFCs mass in kg, requires amendment of Supp. to the IAPPC.
  • Prohibits the use of virgin HCFCs?
  • Introduces reporting requirements/agreements between IMMARBE and NOO?
  • Accelerated phase-out HCFCs?
  • Inclusion of the shipping sector in Belize’s Baseline?
draft msn 11 40
Draft MSN-11-40
  • Establish a link to the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships, 2009.
