Scope and Application

This Guide is applicable to liquefied gas carriers falling under the scope of the International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code) and the ABS requirements under Part 5C, Chapter 8 of the ABS Rules for Building and Classing Marine Vessels (Marine Vessel Rules) and having design features suitable for the carriage of LNG at a future date.

The submitted design is to be in accordance with the requirements of this Guide and the current edition of the specified codes and rules, as referenced herein.

This Guide generally applies to hull structures, systems and equipment that have been installed on a vessel in compliance with the Marine Vessel Rules at the time of vessel new construction.

The guide offers the option to review the overall future conversion design concept for the carriage of LNG cargo (See Section 3).

The requirements for the design and construction of all features of systems proposed are established in the Marine Vessel Rules.

Details of all hull structures, systems and equipment covered by this guide are to be submitted for review to ABS for the design and construction for the carriage of Primary Cargo (e.g., LPG, LEG, Ethylene, etc.) and LNG.

For the purposes of this guide, the term "Primary Cargoes" are those cargoes the vessel is originally certified to carry as described in the vessel's Certificate of Fitness (COF).

Upon completion of the installation to the Surveyor's satisfaction, the vessel will be eligible for the class notation LNG Cargo Ready, including descriptive letters as a record comment (See Subsection 2/1) for the component or systems that have been installed in accordance with approved documents. The record comment descriptive letters are to supplement the LNG Cargo Ready class notation when the component or system indicated has been ABS approved/surveyed as per the applicable rule requirements and installed/tested on board to the attending Surveyor's satisfaction (with the exception of final LNG gas trials).

The LNG Cargo Ready notation is to be applied in combination with either the Liquefied Gas Carrier or Liquefied Gas Carrier with Independent Tanks notations. Examples:

• Class Notation:

A1, Liquefied Gas Carrier, LNG Cargo Ready,AMS…

A1, Liquefied Gas Carrier with Independent Tanks, LNG Cargo Ready,AMS…

• Record Comment:

LNG Cargo Ready (CC, CP, …)

Note: Once the vessel has been converted to carry LNG as a cargo in compliance with the Marine Vessel Rules, in accordance with approved plans and to the satisfaction of the Surveyor, the above "LNG Cargo Ready" notation will be dropped. The IGC Code Certificate of Fitness (COF) will be updated to include the carriage of LNG as cargo.
