Once the meeting is finished, a “Ship/Shore Safety Checklist or Ship to Ship Transfer Checklist (for
STS Operation) must be completed and signed in agreement by both parties.
Ullage measurement and Cargo Quantity Calculation For cargo operation
, various parameters such as water measurement, temperature, ullage and sampling are carried out by shore side terminal side representative or surveyor. Chief officer must ensure one watch officer attend and assist the terminal surveyor for measurements to calculate the cargo quantity. It is the watch officers responsibility to check all the ullage ports (vapor locks) and other openings are shut and closed once the surveyor does the measurement. The watch officer should also note down all the readings acquired by the port surveyor for cargo measurement.

onboard, and while boarding them surveyors or crew members have faced accidents and suffered severe head and spine injuries
• The ship has to be securely moored alongside the terminal or to a floating assembly to ensure it does not move during the operation
, wherein the vessel can become light and float up or get heavy and settle down
15. l Marine Insight For discussing safety and operational matters prior commencing the cargo operations, a ship/shore meeting is carried out between the vessel and the terminal representatives. Following points are reviewed before the ship/shore interface begins
• Means of safe access have to be provided between the ship and the shore by ships gangway or shore gangway. In case of a ship to ship transfer, a personal transfer basket is often used
• The gangway should be as dry as practicable
, obstruction free and devoid of oil stains or slippery surface
• There have been numerous incidents in the past when gangways were not appropriately secured Ship Gangway Image Credit- Josh Wilsoon Cargo Operations for Tanker I 16.
• Standard means of communication are portable UHF radios or walky-talkies. It is to note that ships VHF radio can also be used as a mode of, communication. A primary and backup channel or mode of communication must always be defined before starting any cargo operation at the port
• In case of fire onboard or at the terminal, the vessel is required to rig towing pennants, which are also called Fire Wires
• These wires are rigged on the opposite side to which the loading arms are connected. Using them, a vessel can be towed and immediately taken out of the port limits or terminal
• Most of the terminals require eyes of the towing pennants to be hanging around 1 meter above the water level at all times
17. l Marine Insight
• The means and mode of communication between the ship and shore must be established, and the procedures should be discussed and agreed upon It is very vital for the duty officers to understand and recognize normal and emergency signals for communication.”
