Abstract

The invention discloses a bulky transport ship with a raised bilge. The bulky transport ship comprises an oblique straight bilge plate and a bottom side tank bevel; the relationship between the distance between the bottom side tank bevel and the side plate of the transport ship and the ship width of the transport ship meets: H2=0.33H+ / -5%, wherein H2 is the distance between the bottom side tank bevel and the side plate of the transport ship, and H is the ship width of the transport ship; and the relationship between the distance between the bottom side tank bevel and the inner hull of the transport ship and the cargo space width of the transport ship meets: b2=0.28b+ / -5%, wherein b2 is the distance between the bottom side tank bevel and the inner hull of the transport ship, and b is the cargo space width of the transport ship. The bulky transport ship disclosed by the invention has the advantages that the ballast water volume required for immersing propellers is small, the oil consumption in a ballast state is low, and the block coefficient is smaller and the oil consumption is reduced in a non-full load state.

Description

technical field [0001] The invention relates to the technical field of transport ships, in particular to a fat transport ship with raised bilge. Background technique [0002] With the establishment of two ship energy efficiency standards of "Ship Energy Efficiency Design Index" (ηEEDI) and "Ship Energy Efficiency Management Plan" (SEEMP) by IMO, as well as the mandatory implementation of the "Ballast Water Convention", the reduction and control management of greenhouse gas emissions in international maritime shipping has come to the fore. The need for species to invade a country's ecology has been generally accepted by the international community. In this context, new ships and some old ships need to install ballast water treatment devices. Therefore, cost control and reasonable use of hull space have become a top priority. At the same time, technical emission reduction measures such as reducing the energy consumption requirements of ballast water treatment devices, hull li...
