MOORING, ANCHORING, & TOWING OPERATIONS Flashcards
Q1: What is the primary function of ground tackle in anchoring operations?
A1: The primary function of ground tackle is to secure the ship at anchor. It includes the anchor, chain, and associated equipment necessary for deploying and retrieving the anchor to ensure the ship remains in a fixed position. (NAVSEA S9086-TV-STM-010, Chapter 581)
Q2: Describe the steps involved in preparing ground tackle for anchoring.
A2: Steps involved in preparing ground tackle for anchoring include inspecting the anchor and chain for wear and damage, ensuring the windlass and brake are functional, and preparing the anchor for release by removing lashings or stoppers. (NAVSEA S9086-TV-STM-010, Chapter 581)
Q3: What are the key procedures for deploying an anchor?
A3: Key procedures for deploying an anchor include selecting a suitable anchorage, paying out the appropriate length of chain (scope), releasing the anchor under control to prevent damage, and ensuring the anchor is set firmly into the seabed. (NAVSEA S9086-TV-STM-010, Chapter 581)
Q4: Explain the process of weighing anchor.
A4: The process of weighing anchor involves reversing the steps used to deploy the anchor: ensuring the chain is vertical, engaging the windlass to lift the anchor, washing down the chain and anchor to remove seabed material, and securing the anchor in its housing. (NAVSEA S9086-TV-STM-010, Chapter 581)
Q5: What equipment is included in ground tackle for mooring operations?
A5: Ground tackle for mooring operations includes mooring lines, fenders, bollards, chocks, cleats, and winches. These components work together to secure the vessel to a pier, dock, or mooring buoy. (NAVSEA S9086-TW-STM-010, Chapter 582)
Q6: Describe the procedures for a standard mooring operation.
A6: Procedures for a standard mooring operation include approaching the mooring site at a controlled speed, using fenders to prevent damage, deploying mooring lines to shore personnel or bollards, securing lines to winches or cleats, and adjusting line tension as needed. (NAVSEA S9086-TW-STM-010, Chapter 582)
Q7: What are the primary considerations when planning a towing operation?
A7: Primary considerations for planning a towing operation include assessing the condition and strength of towing equipment, determining the towing route and environmental conditions, ensuring clear communication between the towing and towed vessels, and preparing emergency procedures. (NAVSEA SL740-AA-MAN-010, U.S. Navy Towing Manual)
Q8: Explain the procedures for connecting a towing hawser to the towed vessel.
A8: Procedures for connecting a towing hawser include positioning the towing vessel appropriately, passing the messenger line and hawser to the towed vessel, securing the hawser to the tow point, and gradually taking up slack while maintaining communication to ensure proper alignment and tension. (NAVSEA SL740-AA-MAN-010, U.S. Navy Towing Manual)
Q9: What are the safety precautions to be taken during mooring operations?
A9: Safety precautions during mooring operations include wearing appropriate personal protective equipment, keeping clear of snapback zones, maintaining situational awareness, ensuring all equipment is in good condition, and using proper hand signals for communication. (NAVSEA S9086-TW-STM-010, Chapter 582)
Q10: How should the condition of mooring lines be monitored and maintained?
A10: The condition of mooring lines should be monitored through regular inspections for wear, chafing, and damage. Lines should be replaced as needed, and chafing gear should be used to protect them at contact points. Proper stowage and care extend their service life. (NAVSEA S9086-UU-STM-010, Chapter 613)
