The three IMO gas carrier codes- A handy summary

igc-code-wideGas tankers are covered by a confusing array of codes, there before this series looks at the  Certificate of fitness for carriage of liquified gases in bulk, it will give a quick summary of those codes.

The three Gas carrier codes

The year of build of a vessel will determine which code applies.

  • ICG code: The International Code of the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk GC Code- 1986
  • GC Code: Code for the Construction Equipment of Ships Carrying Liquefied Gases in Bulk-1983
  • EGC Code: Code for Existing Ships Carrying Liquefied Gases in Bulk-1976

The ICG code

The International Code of the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (1986)

This was adopted by resolution MSC.5(48), has been mandatory under SOLAS chapigc-codeter VII since 1 July 1986. The IGC Code applies to ships regardless of their size,  engaged in carriage of liquefied gases having a vapour pressure exceeding 2.8 bar absolute at a temperature of 37.8°C, and certain other substances listed in chapter 19 of the Code.

The aim of the Code is to provide an international standard for the safe carriage by sea in bulk of liquefied gases  by prescribing the design and construction standards of ships involved in such carriage and the equipment they should carry.


The GC Code

Code for the Construction Equipment of Ships Carrying Liquefied Gases in Bulk (GC Code) (1983)

gascode1983

This Code was developed to provide an international standard for the safe carriage by sea in bulk of liquefied gases and certain other substances. The Code generally applies to ships built on or after 31 December 1976 but prior to 1 July 1986. 


EGC Code

Code for Existing Ships Carrying Liquefied Gases in Bulk (1976)

The purpose ogascode1976f this Code is to provide international standards for the safe carriage of liquefied gases in bulk by ships which are currently in service, or which otherwise fall outside the scope of the more extensive standards contained in resolution A.328(IX). The Code generally applies to ships delivered before 31 December 1976.

The Ballast Water Management Convention is almost here

aquariamcircleeditedBWC- a quick guide to implemtation

Controlling the spread of invasive species


Implementation Date 8 September 2017


Another quick pause from the stream of certification posts to have a peer into some of the key facts about implementing the ballast water convention.

When must a ship comply with the standards defined in the Ballast water Convention?

Resolution A.1088(28) Application of the International Convention for the control and management of ship’s ballast water and sediments 2004

“4 notwithstanding paragraph 2.2, where the Convention enters into force after the year 2016, a ship subject to regulations B-3.1.2 or B-3.4 will not be required to comply with regulation D-2 until its first renewal survey following the date of entry into force of the Convention; .

5 a ship referred to in paragraphs 2.1 to 2.4 will be required to comply with either regulation D-1 or regulation D-2 until such time as regulation D-2 is enforced;

.6 the renewal survey referred to in paragraphs 2.1 to 2.4 is the renewal survey associated with the International Oil Pollution Prevention Certificate under MARPOL Annex I;

In simple terms as from 8 September 2017 a ship must comply with D-1 (ballast water exchange) or D-2 ( Ballast water standards), and after that date, on renewal of its IOPP certificate, it must comply with D-2.
