New Wave Data Underpins Ship Structural Integrity

The loss of the Stellar Daisy in 2017 was a tragic reminder of the importance of wave data to ship design and operation. The vessel sank in the South Atlantic Ocean, with 22 of 24 crewmembers lost. The structural failure of the vessel was attributed to several factors including material fatigue and the forces imposed on the hull as a result of the weather conditions.Survey requirements for some vessel types have since been tightened, but even before this tragedy, work was underway to evaluate the wave data used to determine ship structural integrity requirements.

ClassNK Releases Strength Guidelines Based on Latest Wave Data

Source: ClassNK

ClassNK has released "Guidelines for Direct Load Analysis and Strength Assessment (Edition 3.0)" following the revision of IACS Recommendation No. 34 earlier this year.The guidelines specify the requirements for conducting hull strength assessments based on the latest wave data.IACS Recommendation No. 34 provides advice on sea states as well as wave spectrum, spreading, heading distribution and vessel speed. Its wave statistics are intended for use in the design of sea-going ships above 90 meters (295 feet), including the effect of bad weather avoidance.
