Guidelines for Requirements of the Thermal Analysis for the Hull Structure of Ships Carrying Liquefied Gases in Bulk published by LR

Classification Society Lloyd's Register has published the Guidelines for Requirements of the Thermal Analysis for the Hull Structure of Ships Carrying Liquefied Gases in Bulk.

This ShipRight procedure document was published on January 1st, 2023.

This document is based on the requirements of thermal analysis for the hull and tank structure of ships carrying liquefied gases in bulk in accordance with the International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code), and the relevant Lloyd’s Register Rules and Regulations for the Construction and Classification of Ships for the Carriage of Liquefied Gases in Bulk (commonly referred to as the Rules for Liquefied Gases).

It is intended to provide guidance to support designers, Operators, and LR Surveyors to carry out thermal analysis based on the requirements for the hull structure of liquefied gas ships.

This document presents general methods of temperature distribution calculation of the hull structure and thermal stress analysis of the tank structure of liquefied gas ships.

This document is, in general, applicable to liquefied gas ships with the following tank configurations:

• Membrane tank
• Type B spherical tank
• Type B prismatic tank
• Type A tank
• Type C tank
