Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] This embodiment is illustrated by the bulbous bow renewal of the Maersk company "Boston" container ship. Replace the old bulbous bow with a new bulbous bow that is straight, thinner and smaller in size, so that the ship can obtain less sailing resistance at the same speed, so as to reduce the power of the main engine, reduce the fuel consumption of the main engine, and reduce the shipping cost. cost purposes. The entire bulbous bow renewal is carried out by the vehicle-mounted bulbous bow overall renewal process, including the segmental prefabrication of the new bulbous bow and the middle group, the cutting of the old bulbous bow, the drawing of positioning lines, reference lines and guide lines on the bottom of the dock, and the docking The layout of the pier is adjusted, and elevated buttresses are added on both sides of the...

Abstract

The invention discloses a vehicular bulbous bow integral-replacing process and belongs to the technical field of ship repair and construction. By sectionally prefabricating and assembling a new bulbous bows and cutting an old bulbous bow, the vehicular bulbous bow integral-replacing process mainly includes steps of marking a positioning line, a datum line and a guide line on a dock bottom surface, arranging and adjusting a docking block, additionally arranging lifting buttresses on two sides of a bow portion, integrally packing the old bulbous bow and the new bulbous bow, disposing a split positioning machine and accurately centering, positioning and folding. The vehicular bulbous bow integral-replacing process has the advantages that docking period is shortened to 15 days from existing 30-40 days; prefabricating and assembling of the new bulbous bow are realized in a machine room, engineer quality and construction accuracy can reach novel shipbuilding level; operation is convenient, reliable and quick, alignment speed and accuracy are greatly increased, workload is greatly reduced, and labor intensity and labor cost are reduced; occupation time of shipyard equipment and facilities is short, and production cost of replacement of the bulbous bow is reduced. The vehicular bulbous bow integral-replacing process can be widely used for the fields of ship repair and construction.

Description

technical field [0001] The invention belongs to the technical field of ship repair and construction, and specifically relates to a vehicle-mounted bulbous bow overall renewal process. Background technique [0002] According to the ship type and shipping needs, most traditional container ships are designed with a relatively large bulbous bow, and some are even designed as a bulbous bow with an upturned bow, so that the bulbous bow is consistent with the overall shape of the container ship. , sea conditions and ship speed form an adaptation, and the best seaworthiness of the ship can be obtained when sailing at high speed under severe sea conditions. The design of this kind of hypertrophic bulbous bow or bulbous bow with an upturned bow end, while the ship obtains the best seaworthiness, the hypertrophy bulbous bow or the upturned part will also bring greater pressure to the navigation of the ship. The resistance, especially when the container ship is sailing at full speed, t...
