and gravity of the cargo in each
material data sheet for each cargo, including all hazards associated
with handling of and treatment for exposure, inhalation and ingestion of this
if H2S cargo, the H2S concentration (ppm) by weight in oil
cargo loading rates
number of shore pumps to be used; will loading be started by pump
or gravity flow
shore pipeline displacements planned before, between and after loading/grades

procedures to be used while loading
quantities of ballast or slops to be pumped ashore and contents
of the slops
preferred sequence of loading (if multiple grade cargo)
procedures for changing grades of cargo

D. Loading plan and method of loading – operational agreement
Based on the information obtained during the meeting with the terminal representative
the Chief Officer should prepare a bar chart time diagram to illustrate the
anticipated loading operation. He/she should review the time diagram with
the Master and, after any necessary revisions, give a copy to the shore terminal
and post a copy in the cargo control room (CCR).
The time diagram indicates graphically the sequence and timing of the various
steps of the loading operation and provides an indication of the time when
the operations should be completed.
The declaration of inspection, exchange of information and the loading plan
together constitute an operational agreement for the loading of the vessel.
This agreement is complete when and only when the person in charge of the
shore terminal and the person in charge of the vessel have both signed the
declaration of inspection.
