Annex - Unified Interpretations of the IGF Code

1 Storage tanks loading limits higher than calculated using the reference temperature (paragraph 6.8.2)

The alternative loading limit option given under 6.8.2 is understood to be an alternative to 6.8.1 and should only be applicable when the calculated loading limit using the formulae in 6.8.1 gives a lower value than 95%.

2 Other rooms with high fire risk (paragraph 11.3.3)

The following "other rooms with high fire risk" should as a minimum be considered, but not be restricted to:

  • .1 cargo spaces except cargo tanks for liquids with flashpoint above 60°C and except cargo spaces exempted in accordance with SOLAS regulations II-2/10.7.1.2 or II-2/10.7.1.4;

  • .2 vehicle, ro-ro and special category spaces;

  • .3 service spaces (high risk): galleys, pantries containing cooking appliances, saunas, paint lockers and store-rooms having areas of 4 m2 or more, spaces for the storage of flammable liquids and workshops other than those forming part of the machinery space, as provided in SOLAS regulations II-2/9.2.2.4, II-2/9.2.3.3 and II-2/9.2.4; and

  • .4 accommodation spaces of greater fire risk: saunas, sale shops, barber shops and beauty parlours and public spaces containing furniture and furnishing of other than restricted fire risk and having deck area of 50 m2 or more, as provided in SOLAS regulation II-2/9.2.2.3.

3 Level indicator in the bilge well of tank connection spaces of independent liquefied gas storage tanks (paragraph 15.3.2)

The "level indicator" required by 15.3.2 of the IGF Code is understood to be required for the purposes of indicating an alarm status only; a level switch (float switch) is an instrument example considered to meet this requirement.

4 Testing of high level alarms (paragraph 15.4.2.3)

The expression "each dry-docking" refers to:

  • .1 for cargo ships, the survey of the outside of the ship's bottom required for the renewal of the Cargo Ship Safety Construction Certificate and/or the Cargo Ship Safety Certificate; and

  • .2 for passenger ships, the survey of the outside of the ship's bottom to be carried out according to paragraphs 5.10.1 and 5.10.2 of the Survey Guidelines under the Harmonized System of Survey and Certification, (HSSC), 2017 (resolution A.1121(30), as may be amended).
