After the reconnaissance survey performed at beginning of this year, the difficult areas to be crossed have been identified. They require a higher resolution for the suitable routing and further the several in-service cables crossing the EAI route also require to be identified for finalizing the crossing agreements with the other cable systems Operators.

The Scope of the survey is to achieve a sufficient detail of the seabed features generally along the entire route, i.e. at any water depth but also a good sub bottom profiling and side scan sonar down to 700 — mwd, where the burial assessment is requested and beyond as necessary for both featuring the surface geology and to assess the sediment structure for the cable protection by burial. The difficult identified areas will require more attention in order to select the suitable acceptable routing on line.

As for burial assessment, a geo-technical campaign will be performed after the detailed geophysical survey, in order to perform soil sampling by gravity and vibro corers and cone penetrometer test (CPT) at discrete intervals and locations determined by the geophysical results of Sub bottom profiler (SBP).

Given the length for the whole survey, the extended deep water areas, the high required resolution, ROV's and possibly AUV's will need to be employed to increase the resolution of swath bathymetry (MBES); Side scan Sonar (SSS) and SBP and on board Data processing and charting shall be performed for the route design process, in connection with shore based Processing teams.

The timing constraints will probably oblige the task sharing in sequence by employing different vessels of different capabilities for the AUV and ROV and for the nearshore and shallow water and for the geo-technics, with further sharing according to the links as necessary to stay in the planned time of possibly no more than 13 months of operation at sea, depending on the variable factors as weather, number of samples and crossing inspection, etc.

It is envisaged a simultaneous operation for the nearshore survey by 2 or 3 vessels up to 50-100 mwd depending on the distance from the coast as daytime work. 1 or 2 Vessels for the Geophysical survey performed from surface and by AUV and ROV for the cable crossing identification and 1 Vessel or even 2 for the geo-technical Campaign.

The preliminary reporting will be performed on board but reworked and integrated on shore at Contractor's premises, even in different sites as the survey proceeds, according to the program that will be better developed and set up after the bidding process. It is clearly necessary a great effort to coordinate the different tasks and also the reporting in such a way that the results would be presented with the same quality, structure and effectiveness.

After the draft final report delivery for each link, this will be reviewed and the burial assessment study may be started, as well the installation engineering. Both ones of these tasks would be completed well after the delivery of the final reviewed survey reports.
