Anchors

When stationary, the ship is affected by wind, water resistance force, impact force of waves and other random forces. The anchor is a device, normally made of metal, used to connect a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. Permanents anchors are used in the creation of a mooring, and a rarely moved.

Main anchor (or stop anchor) are usually located at the bow, because it has a drainage form that reduces the resistance used to fix the vessels. Drag anchor are placed at the stern to prevent the vessel from spinning while anchored, to avoid the impact of water flowing into the propeller and rudder. To avoid drifting the ship, use small anchor to perform this function.

- Anchors are made of cast steel, forge steel or rolled iron

► Equip with anchors:

• The vessels must be equipped with anchors suitable for their dimension to ensure ability to hold the vessel
• The vessels must be equipped at least 2 bow anchor. If a third anchor is provided, it should be connected to a dedicated anchor chain and placed on board to be ready for immediate use
• The anchor arrangement must be such that damage and twisting of the chain can be avoided. Appropriate equipment shall be located to hold the anchors securely under all operating conditions
• All equipment of anchor system, tie flange, guide pulley and missing rings shall be structured and linked to the hull so that under the design load the integrity of the hull isn’t lost
