USCG Boatswain Manual Ch. 4 §4.1

USCG Boatswain Manual Ch. 4 §4.1 — Deck Safety Deck PPE includes hardhat in cargo or rigging operations, ANSI-rated work boots with non-slip soles, high-visibility vest, gloves appropriate to the task (cut-resistant for wire, leather for line), and hearing protection where engine or compressor noise exceeds 85 dB.

46 CFR §177.900

§ 177.900 Deck rails. (a) Except as otherwise provided in this section, rails or equivalent protection must be installed near the periphery of all decks of a vessel accessible to passengers or crew. Equivalent protection may include lifelines, wire rope, chains, and bulwarks, which provide strength and support equivalent to fixed rails. Deck rails must include a top rail with the minimum height required by this section, and lower courses or equivalent protection as required by this section. (b) Deck rails must be designed and constructed to withstand a point load of 91 kilograms (200 pounds) applied at any point in any direction, and a uniform load of 74 kilograms per meter (50 pounds per foot) applied to the top rail in any direction. The point and uniform loads do not need to be applie…

46 CFR §182.220

§ 182.220 Installations. (a) Except as otherwise provided in this section, propulsion machinery installations must comply with the provisions of this part. (b) The requirements for machinery and boilers for steam and electrically propelled vessels are contained in applicable regulations in subchapter F (Marine Engineering) and subchapter J (Electrical Engineering) of this chapter. (c) Propulsion machinery of an unusual type for small passenger vessels must be given separate consideration and is subject to such requirements as determined necessary by the cognizant OCMI. These unusual types of propulsion machinery include: (1) Gas turbine machinery installations; (2) Air screws; (3) Hydraulic jets; and (4) Machinery installations using lift devices.

NAVEDTRA 14067 §4-1

NAVEDTRA 14067 §4-1 — Deck fittings and line-handling safety Deck fittings are the fixed points to which lines are led and made fast. Bitts are paired vertical posts (usually welded to the deck) around which mooring and towing lines are figure-eighted and secured; cleats are horn-shaped fittings for smaller lines; chocks are fairleads (open, closed, or roller) through which a line passes over the side, changing its lead without a sharp bend and protecting it from the deck edge; bollards are the shoreside posts a ship's eye is dropped over. A line is "made fast" to bitts by taking a round turn on the after bitt then figure-eights across both bitts, finished so it can be surged or slipped. To surge a line is to let it slip around the bitts or a warping head in a controlled way, taking the s…

NAVEDTRA 14343 §4-3

NAVEDTRA 14343 §4-3 — Anchor windlass and wildcat operation (deck machinery) The anchor windlass is the deck machine that heaves in and pays out the anchor chain and holds the anchor at the hawsepipe. Its principal parts are the wildcat (a notched, sprocket-like drum whose pockets, or whelps, are shaped to grip each link of chain), the wildcat clutch (or locking head) that connects the wildcat to the drive shaft, the brake band that controls the wildcat when it is declutched, and the prime mover (electric, hydraulic, or steam). Most windlasses also carry gypsy heads (warping heads) on the shaft ends for handling mooring lines. To let go the anchor: with the wildcat declutched and the brake holding, the riding pawl or devil's claw and any chain stopper are removed, then the brake is eased …

NAVEDTRA 14343 §8-3

NAVEDTRA 14343 §8-3 — Standing and running rigging; fittings Rigging is divided into standing rigging — the fixed wires that support masts, kingposts, and booms (stays, shrouds, guys, and pendants) — and running rigging, the ropes and wires that move over sheaves to do work (falls, halyards, cargo runners, topping lifts). Standing rigging is set up taut and secured with fittings and adjusted by turnbuckles. Common rigging fittings and their uses: shackles (U-shaped connectors closed by a pin) join lines and gear — anchor/bow shackles for round loads, chain/ D-shackles for in-line pulls; a thimble is a grooved metal eye spliced or swaged into a rope's eye to protect it from chafe at the connection; a turnbuckle (rigging screw) has right- and left-hand threaded eyes so turning the body tens…
