Slide 4: The decks aboard ship are the same as the floors in a house. The main deck is the first continuous watertight deck that runs from the bow to the stern. In many instances, the weather deck and the main deck may be one and the same. Any partial deck above the main deck is named according to its location on the ship. Slide 5: At the bow it is called a forecastle deck, Amidships it is an upper deck, and at the Stern it is called the poop deck. The term weather deck includes all parts of the forecastle, main, upper, and poop decks exposed to the weather. Any structure built above the weather deck is called superstructure. Deck Fittings : Deck Fittings LEARNING OBJECTIVE:Recognize common deck fittings found aboard ships and explain their purpose. Deck fittings are the various devices attached to the hull that assist in handling the ship. The most common fittings are found around the weather decks. Deck Fittings and Mooring Equipment : Cleat - Consists of a double-ended pair of horns, used for securing a line or wire. Bitts - Pairs of heavy vertical cylinders, used for making fast lines led through chocks. Bollard - Strong cylindrical upright on a pier, about which a mooring line is placed. Deck Fittings and Mooring Equipment Slide 8: Chock - Heavy fitting with smooth surfaces through which mooring lines are led. Roller Open Closed Slide 11: BOLLARDS A bollard is a strong cylindrical upright on a pier, over which the eye (or bight) of a ship’s mooring line is placed. Slide 12: Padeye - A metal plate with an “eye”, attached to the deck to distribute a load over a large area. Lifelines - Lines erected around the edges of decks, referred to as follows: Top - Lifeline Middle - Housing line Bottom - Foot rope Snaking - Netting rigged between foot rope and deck. Slide 13: Capstan - Separate vertical machinery units or part of the anchor windlass around which lines are passed, commonly used in mooring and anchoring evolutions. Slide 14: Camel - A large float or raft used as a fender. Rat guards - Shields secured around mooring lines to prevent rats from coming board ships. Slide 15: Chafing gear - Canvas or other material placed around mooring lines to prevent wear. Fenders - Material designed to absorb the shock of contact between two ships or a ship and a pier. Slide 16: Boatswain’s chair - Used for sending one person over the side. Jacob’s ladder - Rope ladder w/rungs rigged over the side for temporary use Boat boom - Spar swung out from the side of the ship, permits small boats to ride safely alongside while at anchor. Slide 17: Pilot’s ladder - Flexible portable ladder, usually constructed of metal, sturdier than a Jacob’s ladder. Sea ladder - Rigid, portable ladder that maybe rigged to the side of the ship. Accommodation ladder - Rigid, inclined ladder rigged to the side of the ship to allow boarding of a moored or anchored ship. Mooring : Mooring When mooring, ensure that all line handlers are in safe zones when working tensioned lines. Keep an eye on the tattletales and on the general motion of the ship. Mooring : Mooring Avoid a parted line by keeping the bridge informed as line tension increases and by watching what is happening around the line. Standard Commands to Line Handlers. Mooring Lines : Mooring Lines Mooring lines are the lines used to secure the ship to a wharf, pier or another ship. It is subjected to a great deal of strain while mooring and unmooring the vessel. The angle of pull and the shock loading forces often applied to these lines are usually never considered. Slide 21: The size of bitts, the angle of pull on mooring lines and the size of the eye spliced in the mooring lines are all important.. Here are three considerations that should always be kept in mind when working mooring lines: 1. Characteristics. Any sharp bend in a rope, under load, decreases its strength. Slide 22: Usage. Where a rope bends more than 10 degrees around bitts or chocks or is bending across any surface, the diameter of the surface should be at least three times the diameter of the rope. Slide 23: 3. Eye Splices. The ratio of the length of an eye-splice to the diameter of the object over which the eye is to be placed (bollard, bitt, cleat, etc.) shall be a minimum of 3 to 1, preferably 5 to 1. If you have a bollard two feet in diameter, the eye splice should be six to ten feet in length. Definition of lines: : Definition of lines: Breast lines - Run at right angles from the ship, control distance of ship from pier. Aft spring lines - Tend aft from ship, control forward movement. Forward spring lines - Tend forward from the ship, control aft movement Mooring Lines : Mooring Lines Mooring Lines : Mooring Lines Numbering of lines: #1 - Bow line #2 - Aft bow spring line #3 - Forward bow spring line #4 - Aft quarter spring line #5 - Forward quarter spring line #6 - Stern line 1 3 4 5 6 2 Mooring Lines : Mooring Lines DO NOT MIX MOORING LINE Never mix lines of different constructions or material . Each type of rope exhibits different elongation characteristics and mixing will result in an unequal load sharing. Working with lines and rope : Working with lines and rope Gloves When working with wire rope, a person must wear gloves. There are many "fishhooks" (fragments of wire) that can cut a hand, and the grease that covers most rope is not good for an open cut. Slide 32: Working with lines and rope Gloves When handling line, however, a person should generally not wear gloves (avoids getting caught in lay of line) Keep hands at least 18 inches from a bit, pad-eye, or snatch block. Dip the Eye : Dip the Eye When two bights are placed on the same bollard, the second one is led up through the first before being put over the bollard. This allows either to be cast off without moving the other. DECK MACHINERY : DECK MACHINERY Slide 35: Includes the standard machinery found on the decks. The size and shape of the deck machinery may vary depending upon type of vessel, but the operating principles remain the same. Cargo Winches are power-driven machines used to lift, lower, or move cargo. Winches are classified according to their source of power. Electric winches are standard equipment on most vessels. Slide 36: Electric Winch Slide 37: An electric winch has a steel base on which the winch drum, motor, gears, shafts, and brakes are mounted. The drum, which has cable wound on it, is usually smooth with flanged ends. It revolves on a horizontal axis and is driven through single or double reduction gears by an electric motor (usually direct current). A solenoid brake and a mechanical brake are fitted to the motor shaft. Slide 38: An electric winch has a steel base on which the winch drum, motor, gears, shafts, and brakes are mounted. The drum, which has cable wound on it, is usually smooth with flanged ends. It revolves on a horizontal axis and is driven through single or double reduction gears by an electric motor (usually direct current). A solenoid brake and a mechanical brake are fitted to the motor shaft. Windlass : Windlass The Windlass is a special type of winch used to raise and lower the anchors and to handle the forward mooring lines. It consists of a wildcat (a steel casting in the form of a deeply grooved drum with projecting ribs [whelps]) used to grip the anchor chain, controls for connecting or disconnecting the wildcat from the engine, and a friction brake which can be set to stop the wildcat when disconnected. There are horizontal drums at each end of the windlass for warping. Slide 40: There are horizontal drums at each end of the windlass for warping. Windlass Capstan : Capstan The Capstan is a vertically mounted winch head used aboard ship when mechanical power is required for raising anchor, lifting heavy weights, or for any similar work. It is a cast steel drum mounted on a vertical spindle with the largest diameters at top and bottom and the smallest in the middle to allow the rope around it to surge up or down as the number of turns are increased. The drum is fixed to the spindle by keys. Slide 43: Capstan Ship’s Deck Gear : Ship’s Deck Gear Slide 45: Ship’s Deck Gear The term "ship’s gear" is used to describe that gear and equipment aboard ship that is used for cargo transfer activities and deck operations. Ship’s gear can be divided into four categories: Standing rigging. Running rigging. Deck fittings. Deck machinery. Slide 46: STANDING RIGGING Standing rigging gear includes the rigging that supports masts or king posts. This gear includes the following: Shrouds are heavy wire ropes that provide athwartship support for the mast or king posts. Two or more shrouds are used on either side of a mast or king post. They are secured to the outboard side of the deck or to the bulwark to provide maximum support. Slide 47: Turnbuckles are internally threaded collars turning on two screws threaded in opposite directions. They are used to secure and to take up the slack in the shrouds and stays. Stays and Backstays are heavy wires similar to shrouds. The difference is that they will lead in a forward or aft direction and are found at the mast where the jumbo boom (heavy lift boom) is located. Slide 48: When they support the mast: From a forward direction, they are called stays. From an aft (back) direction, they are called backstays.
