Cable burial or protection can take place either in-situ
during installation or post-lay. The in-situ method
utilizes a cable burial plow and post lay involves an
ROV with a cable jetting tool. Burial plows are large
pieces of equipment (9 mtrs long and 18mt) requiring
large handling equipment for launch & recovery.
Plows are not easily mobilized to a vessel of
opportunity.
The ROV, however, is a smaller unit with a smaller
overall footprint which mobilizes very quickly to
vessels of opportunity and can provide required burial
protection of the cables. The downside is that the
cable will not be buried simultaneously with cable
installation.
