USCG Barge Supervisor study plan

Map the full cargo transfer sequence for loading and discharging a barge, listing each valve, manifold, and tank state at every step

Compute displacement, deadweight, and cargo capacity for three sample barges given draft and tank tables

Calculate draft change per inch of cargo for a rectangular and a raked tank

Identify the regulatory and company documents that govern a transfer operation and state what each one controls

Explain the vapor pressure, flash point, and flammable range limits that govern transfer rates for at least four cargo types

Describe segregation and compatibility requirements for loading multiple cargoes on one barge

Sequence the pre-transfer conference agenda and list the persons who must attend

Draft the actions to take when a line or manifold leak is detected mid-transfer

Describe inert gas system operation and state the oxygen and hydrocarbon limits maintained during transfer

Explain how temperature change affects cargo volume and how to correct for it in transfer quantities

Identify hazards of static electricity and list bonding and grounding steps before transfer

State the sampling and gauging procedures required before, during, and after transfer

Compute righting arm, GM, and list using a sample stability table for a barge with an off-center tank

Calculate trim and final drafts after transferring a stated tonnage between two tanks

Determine the free surface correction for partially filled tanks and apply it to a corrected GM

Verify a proposed loading plan against minimum freeboard and maximum draft limits

Outline the notification chain and reporting requirements for a discharge under the applicable pollution regulations

Describe the deployment sequence and limitations of a containment boom around a barge at a transfer facility

List the firefighting agents and tactics appropriate for a tank fire versus a machinery-space fire on a barge

Explain the emergency shutdown sequence and who has authority to order it

Identify the required lifesaving and firefighting equipment carried on a tank barge and state the inspection interval for each item

Describe the tank, cofferdam, and hull structure features that control cargo containment and detect leakage

Explain the inspection and maintenance requirements for cargo pumps, valves, and venting systems

Draft a muster and abandon-ship drill sequence for a barge crew

Apply the navigation rules for meeting, crossing, and overtaking situations to towing and barge configurations

Identify lights, shapes, and sound signals required for a towing vessel with an alongside or astern tow

Describe barge handling considerations in current, wind, and confined water during mooring and transfer

Explain watchkeeping and communication duties of the barge supervisor during transfer

Recite from memory the key limits, intervals, and notification requirements from every domain

Re-solve one stability calculation and one transfer quantity correction without notes

Walk through a full emergency scenario from detection through notification and shutdown

Review all missed items from prior weeks and correct each one in writing
