Method for transforming single-hull tanker into double-hull bulk carrier and double-hull bulk carrier

Abstract

The invention provides a method for transforming a single-hull tanker into a double-hull bulk carrier. The method comprises the steps of cutting an oil pipe and oil conveying equipment on a deck, reinforcing deck refitting, and cutting auxiliary holes in the deck; installing a frame plate and a longitudinal girder at the inner bottom of the ship body, and installing an inner bottom shell on the frame plate and the longitudinal girder; connecting the inner bottom shell with longitudinal bulkheads close to the two sides of the ship body to form a ship body inner shell; changing cabin arrangement, re-planning a cabin wall, dismantling original cargo oil, heating and other piping systems, and adding a ballast system and a sewage system; additionally arranging a high-side cabinet; forming a hatch in a deck, arranging a hatch coaming on the periphery of the hatch, and arranging a hatch cover on the hatch coaming; addtionally arranging a plurality of Clinlin cranes; and carrying out a cabin tightness test and a ship inclination test. According to the method for transforming the single-shell tanker into the double-shell bulk carrier, an existing single-shell tanker is transformed into the double-layer bulk carrier, and therefore the shipbuilding cost is saved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method for transforming a single-hull tanker into a double-hull bulk carrier and the double-hull bulk carrier. Background technique [0002] All kinds of cargo ships (including passenger ships) manufactured before the end of the last century have a layer of hull steel plate outside the keel, sea water outside the steel plate, and cargo holds inside the steel plate. The overall strength of this kind of ship is slightly weaker, especially for oil tankers. , If there is an accident such as collision or hitting a rock, after the single-layer steel plate is broken, the cargo oil will directly leak into the sea, causing an oil pollution accident. Therefore, single-hull oil tankers do not meet the environmental protection requirements of the International Maritime Convention and are ship types that need to be eliminated. However, single-hull oil tankers cannot be discarded directly to w...
