Скачать или смотреть How to drop anchor - Full Anchoring Operation

Anchoring operation is a critical ship maneuver to secure a vessel in a specific location using its anchor, involving detailed planning (weather, depth, seabed), precise navigation to the spot (approaching into wind/current at slow speed), controlled release of the anchor chain ("letting go" or "walking back"), and securing it once the correct chain length (scope) is deployed, all while monitoring for dragging and maintaining engine readiness for emergencies, requiring teamwork between the bridge and forecastle crews for safety.

Key Phases & Steps
Planning: Determine anchor site, water depth, seabed, weather, and required chain length (scope) based on depth and conditions.
Preparation: Ready equipment (windlass, brakes), remove safety devices (lashings, bow stoppers), and brief the crew.
Approach: Navigate slowly (0.3-2 knots) into the wind/current towards the drop point, using engine power to stop over the spot.
Deployment:
Letting Go (Gravity Drop): Release the brake for a free fall (for smaller ships/shallower water).
Walking Back (Controlled): Use the windlass to pay out chain (for larger ships/deeper water).
Release anchor when on location, letting it settle as the ship drifts back.
Securing: Pay out the planned chain length (shackles), fasten the brake, apply the bow stopper, and check for a secure hold.
Signaling: Raise an anchor ball to show other vessels you are at anchor.
Critical Factors
Ship & Anchor Handling Team: Bridge (navigation) and Forecastle (anchor handling) teams work together.
Equipment: Windlass, chain markings (shackles), bow stopper, and anchor.
Conditions: Wind, current, water depth, and seabed type (mud, sand).
Safety: Constant monitoring for dragging, engine readiness, and adherence to procedure.
