What is hull structure?
What is hull structure?
The hull of a ship is the most notable structural entity of the ship. To define the hull, it can be said that it is the watertight enclosure of the ship, which protects the cargo, machinery, and accommodation spaces of the ship from the weather, flooding, and structural damage.
What is Lines plan of ships?
Lines plan means a special drawing which is dedicated to show the entire hull form of a ship.
What do you call the length of the ship measured between the extreme forward edge of the stem and the extreme after edge of the stern?
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member.
What is Loa and LBP?
LBP is the length between the forward and aft perpendiculars measured along the summer load line. Amidships is a point midway between the after and forward perpendiculars. LOA is the length of vessel taken over all extremities.
What are the lines on the bottom of a boat called?
Spring Line: Dock lines used to prevent a boat from moving forward and aft. Stern Line: Dock line secured to the stern of a boat that limits its movement.
What are the three lines plan of a ship?
A lines plan consists of three views: the plan view (a top-down view of the vessel, with waterlines. the profile view (a side-view of the ship, with buttock lines. the body plan view (a view of the ends of the vessel, with station lines)
What is a line plan?
A Line Plan (Range Plan) is a roadmap used for laying out the option counts of a new collection by attributes such as end-use, price band, color group, print type, etc., to ensure alignment between Design, Merchandising, and Sourcing teams.
What mooring line tends forward from the ship and controls its aft movement?
– Spring lines – Mooring lines leading in a nearly fore and aft direction, the purpose of which is to prevent longitudinal movement (surge) of the ship while in berth. Spring lines restrain the ship in two directions: headsprings prevent forward motion and backsprings aft motion.
What is Amidship in ship?
1. A nautical term, which refers to the longitudinal centerline of a ship. 2. In ship construction amidships is in the middle of the length (L).
What is beam and Draught?
Beam: The width of the boat, measured at its widest point. Generally, the larger the beam, the more stable the boat. Draft:The distance between the waterline and the keel of a boat; the minimum depth of water in which a boat will float. Aft: The area towards the stern of the boat. Forward: The area towards the bow.
What is an steamship line?
Steamship line A company usually having the following departments: vessel operations, container operations, tariff department, bookings, outbound rates, inward rates, and sales.

The steamships of the world may be roughly divided into three classes. These are, first, those belonging to mail lines, carrying passengers and mails, and leaving and arriving at certain ports at an advertised time, and with the greatest regularity possible under the circumstances.
What is ship’s geometry and Hull definition?
Ship’s Geometry and Hull Definition. The horizontal planes which are known as waterplanes and their lines of intersection known as waterlines. The transverse sections are defined by intersections of the athwartships planes. The planes which are in parallel to the middle line plane and cut the hull in buttock lines,…
How are the transverse sections of a ship defined?
The transverse sections are defined by intersections of the athwartships planes. The planes which are in parallel to the middle line plane and cut the hull in buttock lines, the middle line plane defines the profile.
