Study Notes
Bulk Carrier Damage Prevention
- Common grab damage during unloading includes damage to ladders, coamings, frames, hopper sides, and tank tops.
- Prevent damage to tank tops by lowering the grab slowly and evenly, maintaining a grip when moving, and exercising caution when there are items on the tank top.
- Prevent damage to hatch coamings and covers by ensuring they are fully open and clear of obstructions.
- Payloaders should operate carefully near ladders and avoid grinding corners of the bucket to prevent damage.
Safe Lightering Operations
- Seven important points for safe lightering operations include a designated person in charge, master's knowledge and responsibility, communication, mooring and unmooring, cargo and cargo transfer equipment use, weather, and operational checklists.
Severe Weather Conditions
- Heavy weather refers to challenging sea conditions including strong winds, high waves, rough seas, and poor visibility.
- Personnel should wear appropriate winter gear, exercise caution on ice decks, and work in groups of two or more on the lee side during heavy weather.
- Machinery should be warmed up in advance and cooling water should be checked for antifreeze in cold weather.
- Check to ensure anchors are properly contained and secured with additional lashings.
- Tighten gangway lashings regularly to prevent movement and damage.
- Ensure cargo is secured with proper lashings, shoring, or tomming as needed.
- Maintain a safe distance from the lee side during heavy weather.
- Check for open caps on ballast, bilge sounding, and temperature pipes to prevent water ingress.
- Consult with the Chief Engineer to reduce engine RPMs to acceptable levels and prevent slamming.
- On container and PCC vessels, modify route and speed in advance to avoid heavy rolling.
- Maintain lube oil sump levels for both the main and auxiliary engines to prevent pumps losing suction.
- Ensure seawater pumps are set to low suction to avoid losing suction during heavy pitching.
