ABS has released its updated Fatigue Assessment of Offshore Structures guide, which incorporates updated approaches for addressing fatigue including new S-N curves and guidance regarding fatigue strength based on fracture mechanics.
Fatigue assessment is a process where the fatigue demand on a structural element is established and compared to the predicted fatigue strength of that element. One way to categorize a fatigue assessment technique is to say that it is based on a direct calculation of fatigue damage or expected fatigue life. Three important methods of assessment are the Simplified Method, the Spectral Method and the Deterministic Method. Alternatively, an indirect fatigue assessment may be performed by the Simplified Method, based on limiting a predicted (probabilistically defined) stress range to be at or below Continue reading “ABS updates Fatigue Assessment of Offshore Structures guide”
A new autonomous landing solution for offshore structures, called the Barge Master gangway, is designed to significantly improves both safety and performance.
Through a combination of radar technology, cameras and sensors, Bosch Rexroth’s system automatically attaches the landing from the ship to the required site without the need for manual input. This means that the operation is consistent and reliable, regardless of weather and ocean conditions.
After the automated landing procedure, the Barge Master gangway is held safely in place through a combination of motion compensation and the ship’s dynamic positioning.
The Workboat Association has published a good practice guide and it is printed and ready for distribution.
“The Carriage of Dangerous Goods on Workboats good practice guide has been developed between the industry and regulators, providing a zero to hero knowledge on both the regulations and best practice associated with the transport of Dangerous Goods by sea on board Workboats,” said Kerrie Forster, Workboat Association CEO.
Written with Seafarers, the vessel management, stakeholders and end-clients all in mind, this guide is set to be an unmissable tool from the education and training of those wishing to operate, work with or contract workboats of any nature.
