Cargo work safety - Self-unloaders procedure
Preventing/Dealing with Spillage’s and Overloads:
It is absolutely essential to avoid any spillage, and belt overload by taking the following
measurements and precautions:-
- Correct training and belt tensioning.
- Adjustment of scrapers.
- Proper control of cargo flow onto the belt.
- Maintaining proper hydraulic line pressures on the gates.
- Careful monitoring of the belt load meter settings in the CCR when operating at maximum
- Frequent inspection of the system to identify any malfunction.
- Maintaining a shore hopper/boom watch to prevent overloading the shore system.
CAUTION: WHEN REMOVING SPILLAGES CLEAR OF THE BELT THE SYSTEM EMERGENCY
STOPS MUST BE ACTIVATED AND TEH BACKSTOPS ENGAGED ANDC HECKED. THE
OPERATION MUST BE CONTINOUSLY SUPERVISED BY A COMPETENT PERSON.
ENSURE THAT THE LIFT BELT BACKSTOPS ARE ENGAGED BEFORE CARRYING OUT ANY
WORK IN THE VICINITY OF THE LIFT BELT AND ITS PULLEY/WHEELS ETC.
Cargo on the Return Belt
When spillage occurs or pieces of cargo bounce off the carrying side of the hold conveyor belt and
falls onto its return side, this cargo will get in between the carriage components and cause
damage to them. Proper control of the cargo flow onto the belt and good belt tracking will
prevent this occurrence. If spillage occurs, the hold conveyor must be stopped, using the pull chord
to clear the spill.

Max Dimension of Cargo per C/P
The C/P states that the maximum size of a stone/rock/piece of cargo, which is allowable is 10 cm in
any direction. Oversized cargo may cause damage to the belt cover, or get stuck in the system
causing further damage. If oversized pieces are noted, samples must be kept aside, and a protest
issued to the Shippers. The relevant Ship Management Office and Owners must be informed
Danger in the Loop Area:
No unauthorised persons are allowed in the Loop area and the CCR must be informed prior to entry.
Crew entering this area must wear protective clothing and exercise caution, as there is danger of
falling cargo, which may have slipped through the loop belt, or fallen off the elevator belt. The Chief
Engineer can restrict entry as necessary.
Loop Water Sprinkler
A water-sprinkler arrangement is provided to protect the Loop House. It is not an automatic
arrangement, and must be turned on immediately in the event of a fire. The water output from this
sprinkler may prove inadequate and is basically to cover the period until fire hoses are ready.
The water sprinkler arrangement must be tested regularly to ensure that the nozzles are not
ND Ultrasonic Testing of the Boom
Regular and thorough visual checks of the Boom structure are to be carried out.
If excessive deflection or fractured welding is sighted, then the Boom structure must be subjected to
dye penetrant testing of all suspect welding. Evidence of cracking of any welding etc is to be
followed by an Ultrasonic examination of the entire Boom Structure by an accredited Company.
Entry Procedure to clear Hang-Ups
- A FULL RISK ASSESSMENT IS TO BE COMPLETED
- The Master must obtain authorisation from the office.
- All personnel must be informed and signs posted.
- Communication must be established, and tested.
- The relevant checklists must be completed.
- Continuous supervision of all persons must be maintained by the Chief Officer
- The hatch covers must be opened in order that all persons in the hold are clearly visible.
- During Entry, a continuous watch on all persons in the hold must be maintained by the Chief
Officer or Deck Officer. keeping the Emergency-Stop control at hand.
- The Emergency stops are to be manned
- Close and isolate all gates.
- Maintain a close watch out for slide, and cave-ins of the cargo.
- Use a loudhailer.
- The condition of hold ladders must be checked regularly, and repaired as required.
- A safety station in the hold must be designated.
- Use safety walk-boards across hog-backs.
- Use short sliding ladders on the saddle-back for an easy cross over to the other side.
- Designate a support team ,to provide and lift-up apparatus.

Operation of sea going bulk carriers involved numerous hazards . Careful planning and exercising due caution for all critical shipboard matters are important . This site is a quick reference to international shipping community with guidance and information on the loading and discharging of modern bulk carriers so as to remain within the limitations as specified by the classification society.
It is vital to reduce the likelihood of over-stressing the ship's structure and also complying with all essential safety measures for a safe passage at sea. Our detail pages contain various bulk carrier related topics that might be useful for people working on board and those who working ashore in the terminal. For any remarks please
