Deep Sea Net fiber optic transport segments are deployed directly from a standard ROV, avoiding the use of a costly cable layer ship. Deployment skid is abandoned on user site ready to connect local sensors and next transport segment. Deep Sea Net is a low consumption network which can be waked on user (or sensor) demand. Lithium batteries and fine power management will give 10 years of autonomy with ¼ of hour operation per day. The innovative approach of Deep Sea Net will permit to build, extend and maintain future sensor networks at very competitive prices.
