Combined type roll-on roll-off lightering ferry

Abstract

The invention discloses a combined type roll-on roll-off lightering ferry. The ferry comprises more than one beach climbing springboard, three rows of buoyancy tank units, more than one pair of mooring systems, more than one springboard lifting device, a pair of power propulsion systems and more than one lightering springboard; the three rows of buoyancy tank units include a ship bow section buoyancy tank unit, an amidship section buoyancy tank unit and a stern section buoyancy tank unit respectively; the bow section buoyancy tank unit, the amidship section buoyancy tank unit and the stern section buoyancy tank unit are detachably connected in sequence in the longitudinal direction to form a ferry body; and the more than one lightering springboards are hinged to the longitudinal middle position of the stern section buoyancy tank unit; the more than one beach climbing springboards are hinged to the middle position of the longitudinal head end of the ship bow section buoyancy tank unit;the more than one pair of mooring systems are arranged on each of the two transverse sides of the ferry body; the more than one springboard lifting devices are installed on the ferry body and are usedfor controlling the angles of the bottom of the beach climbing springboards and the lightering springboards relative to a deck face of the ferry body; and the power propulsion systems are installed in the two transverse sides of the stern section buoyancy tank unit respectively and are used for self-propulsion.

Description

technical field

[0001] The invention relates to the technical field of barge ferry, in particular to a combined roll-on-roll barge ferry. Background technique

[0002] In the task of the ro-ro passenger ship / semi-submersible ship crossing the sea to deliver vehicles and roll-on to the shore, a shallow-draft ferry is needed for the turnover transition from the deep-draft transport ship to the shore. The shallow-draft ferry needs to meet the needs of semi-submersible ship transportation, semi-submersible ship top-to-roll transfer vehicles, and offshore navigation and beach landing.

[0003] The current ro-ro transfer method usually adopts an integral structure ferry, which is limited in that it needs to occupy a large space in the non-working state, and the weight of the single body is large, which is inconvenient for land storage and land transportation.
