Embodiment Construction

[0038] In the following descriptions and claims, unless otherwise specified, all descriptions about directions are explained on the basis that the ship is in a three-dimensional coordinate system, where the length direction, width direction and height direction of the ship correspond to the coordinate system The x-axis, y-axis and z-axis, where the x-axis and y-axis lie in the horizontal plane, and the z-axis lies in the vertical plane. Furthermore, the forward direction of the ship corresponds to the positive x direction.

[0039] This new bow, shown starting from the midship mark 2 of the ship, has an elongated and distinctive bow shape. Figure 1 shows the bow shape 1 of the ship, starting at point A on the baseline 3, and rising with increasing curvature while being drawn forward in the length direction (x direction) to slightly at the design waterline Point B above Tdwl. From point B, the bowline 1 rises further, but with a gradually decreasing curvature and backwards (i...

Abstract

A foreship arrangement for a vessel of the displacement type, which foreship consists of the part of the ship in front of the vessel's midship mark (2) and which vessel has a transversely symmetrical hull form about its centre line (CL) and a substantially conventional bow form below its design water line (Tdwl), characterised in that the stem line (1) of the vessel turns substantially backwards in relation to the length direction of the ship from a transition point (B) at or immediately above the design water line (Tdwl).

Description

technical field [0001] The invention relates to a novel design of the bow of a displacement ship. More specifically, the invention relates to an arrangement as disclosed in the preamble of independent claim 1 . Background technique [0002] Since the beginning of oil development in the North Sea, it has been characteristic of all ships engaged in marine operations to have their bridges and superstructures with equipment placed tightly aft of the forecastle and up to the collision bulkhead. A large cargo deck or working deck is provided aft of the superstructure and wheelhouse. This configuration is a holdover from the first generation of platform supply ships used on the British continental shelf in the 1850s and still predominates today. [0003] When these ships are out of service or waiting (returning) due to weather, they usually turn their bows upwind and into the waves. [0004] The bow is designed to be an inclined bow or straight bow until the design waterline, an...
