wont be able to complete the survey undertow, if their engine room isn't up and running neither will be their air compressors which are needing to make the acoustic boom for the measurements.

But as mentioned, no material delay on FAR and the SNE development, as the sub contractor will have to get another vessel in to complete the contracted job... Time delay only, potential delay in reviewing the data set.
