LR updates ShipRight software for LNG carriers

LNG Industry,


Lloyd’s Register has updated its ShipRight software to allow ship structural fatigue to be assessed.

An enhanced Fatigue Design Assessment (FDA) Level 2 solution is now available, providing a robust tool, which can help owners to reduce their risks. This first release covers oil tankers and membrane type LNG carriers.

The updated tool will help designers, ship owners and operators assess new or existing designs and to help further reduce the risk of fatigue damage in ship’s hull structures.

Cracks and fractures at connections between longitudinal stiffeners and transverse frames of ship’s structures, particularly in large oil tankers with higher tensile steel constructions, were a serious concern in the 1980’s and the early 1990’s. To address these concerns in the early 1990’s, Lloyd's Register introduced ShipRight FDA procedures to promote structural detail design and fatigue performance assessment.

Lloyd’s Register has continuously invested in the development of ShipRight FDA procedures. A new FDA Level 2 module has been incorporated within the ShipRight software which further improves on current technology and makes the assessment tool more robust and versatile.

“We are confident that the new ShipRight FDA Level 2 module gives designers, ship owners and operators an even more reliable tool to further improve the level of confidence in their ship’s fatigue performance. This upgrades our ShipRight software, the industry’s preferred fatigue design assessment tool, to a higher level of usability and accuracy,” explained Jimmy Tong, Technical Manager of Ship Structure Strength at Lloyd’s Register’s Marine Technology and Engineering Services.

Fatigue design assessments, particularly for LNG carriers, become more demanding and challenging, as ship owners often require long fatigue design life in harsh wave environments.

“Designers and owners need to have confidence in the structural performance of the latest generation of these large ships in such harsh wave environments. The fatigue performance of the hull structure is a key component in their operational capability and reliability," Tong concluded.
