Ship operations

SEA SUB SERVICES, has collaborated in 2012 with the development of the SHOAL Project, in Gijón waters. Hand in hand with the Port Authority, our company has carried out the installation of the underwater antennas that formed the field of action of the robot fish, up to a depth of -30 meters. Entrances and exits of the fish to the water, monitoring, filming and maintenance were carried out.

From our company, European engineers carried out the necessary tests to fine-tune the Robot Fish, after three years of work, known as the SHOAL project (from English, bank, swarm, group).

SEA SUB SERVICES has created a sister company for the manufacture, marketing and maintenance of these robotic fish with the intention of reducing costs for customers (up to 50%) in the instantaneous analysis of their waters, and at the same time providing an assistance service. .

It is therefore a question of introducing the robot fish in the European market, teaching its operation “in situ” to the client, demonstrating its operability as the SHOAL project has done, and explaining the economic savings of having the contamination of its waters controlled. (and certified) with this new Robot Fish.

SEA SUB SERVICES, has carried out inspections and repairs to ships

Technological innovation/ R.O.V.

ROVs (Remote Operated Vehicles) are vehicles that are controlled by an operator who is not on the vehicle. Through the cable, the data from the ROV’s cameras, the data from the sensors and the sonars are also transmitted to the control center of the surface ship.

ROVS can carry a wide variety of manipulator arms to carry out work in the depths, or simply a camera to capture images of the seabed.

SeaSubServices/ Submarine Techniques is committed to innovation and technology and therefore has an ROV service (we have 3):

  • Working depth 76 m (250 feet)
  • Dimensions 35 cm (13 ¾ inches)
  • length 22.2 cm (8-¾ inches)
  • width 21.6 cm (8-½ inches)
  • height 3.6 kg (8 lbs.)
  • Hull material anodized aluminum (marine grade)
  • Input voltage 100/240 Volts AC 50/60 Hz
  • Umbilical supply voltage 48
