In accordance with the “Guidelines for Container Stowage and Securing Arrangements” (hereby referred to as “the Guidelines”), we have developed "WACDAS (WAve Climate Data Aggregation for Ships)" as a tool for calculating the route correction factors required for safety assessment of container lashing. WACDAS is an application that enables users to easily calculate route correction factors in a web browser by evaluating the ship motion of individual vessels considering different wave environments depending on the route and season of the actual planned voyage.

In order to use the route correction factors calculated by WACDAS, the lashing software corresponding to the class notation "CSSA-RS" is required in accordance with the Guidelines (2023, 3rd edition or later). The Guidelines are available to download via ClassNK’s website for those who have registered for the ClassNK “My Page”.
