East Anglia THREE– Navigation Risk Assessment 20 Offshore Cable Corridor Maritime Traffic Survey
20.1 Survey Overview 285.
In order to inform vessel routeing in proximity of the offshore cable corridor, 20 days
of AIS data collected from coastal survey stations has been analysed. The 20 day survey period is congruent with the second and third surveys carried out by the Northern Viking survey vessel and therefore covers a period between the 12th to 21st of May 2013 and the 24th July to 3rd August 2013.
20.2 Survey Data by Vessel Type
286. A plot of the tracks recorded during the 20 day survey period, colour-coded by general vessel type categories, is presented in Figure 20.1. Following this, the distribution of vessel types, using the more detailed second-level DECC vessel categories (see Table 11.1) is presented in Figure 20.2
