MANAGEMENT

This Chapter provides a summary of information for assisting the ship and the
terminal jointly to manage personnel and operational safety. Reaction to changing
weather conditions during cargo handling is addressed. The correct use of
personal protective equipment for both ship and shore personnel is also discussed.

The diligent and conscientious joint completion of the Ship/Shore Safety
Check-List provides the foundation for a safe transfer operation. The Check-List
is included in this Chapter, together with guidelines to assist its completion.

This Chapter also includes guidance on the interface between ship and terminal
emergency procedures.

26.1 Climatic Conditions

26.1.1 Terminal Advice of Adverse Weather Conditions
The terminal should establish limiting parameters for controlling or
stopping cargo operations based on the design criteria for the berth and
its equipment. The parameters may be determined by environmental
conditions, such as wind speed, tidal current and swell, or by the physical
limitations of the berth, such as fender loads or mooring point strength.
Any limitations should be discussed with the tanker before operations
commence and recorded in the Ship/Shore Safety Check-List (see
question 48).

The Terminal Representative should alert the tanker to any forecast of
adverse weather conditions which may require operations to be stopped,
or loading or discharge rates to be reduced. In some instances,
necessary information may be provided by third parties in the immediate
vicinity or by the ship.

Where environmental conditions are critical to the operation of the berth,
the terminal should consider providing appropriate measuring
instrumentation to provide information that will assist in managing the
risk.

26.1.2 Wind Conditions
If there is little air movement, petroleum gas may persist on deck in heavy
concentrations. If there is a wind, eddies can be created on the lee side
of a tanker’s accommodation or deck structure which can carry vented
gas towards the structure. Either of these effects may result in local
heavy petroleum gas concentrations and it may be necessary to extend
the precautions set out in Section 24.1 or to stop loading, ballasting of
non-gas free tanks, purging, tank cleaning or gas freeing while these
