The invention discloses a
seabed efficient installation construction method and device for a large-length ultrahigh-pressure
submarine cable, and belongs to the technical field of
seabed submarine cable installation construction. S2, routing sea sweeping; s3, laying the starting end of the
submarine cable on the side of the offshore wind
turbine generator; s4, putting a burying
machine; s5, laying and burying submarine cables; s6, recycling the burying
machine; and S7, laying the
submarine cable terminal at the offshore booster
station side. According to the method, routing sea sweeping is carried out before construction, weather conditions are concerned, construction obstacles are removed in advance, smooth construction can be ensured, the construction period is ensured, and the construction efficiency is improved. During laying construction of the starting end of the
submarine cable on the side of the offshore wind
turbine generator, the barb type
submarine cable protection sleeve is additionally arranged at the submarine cable inlet in the wall of the
tower drum, a good protection effect on the submarine cable is achieved, and particularly, the traction head and the barb type submarine cable protection sleeve are connected in a self-breaking screw connection mode; the barb type submarine cable protection sleeve is installed on a construction ship in advance, the barb type submarine cable protection sleeve is automatically clamped into a submarine cable inlet, and therefore the problems that the installation time is long and the labor intensity is large when a diver carries out
underwater installation are solved.
