TERMINAL MANAGEMENT AND ORGANISATION

A minimum Under Keel Clearance (UKC) should be defined taking into
account speed, squat, ship motion (e.g. due to wave action) and the

nature of the seabed.

Maximum draught should be defined for the usual water density at the
A maximum displacement figure may also be quoted for the berthingย์นาวี
berth.
When defining maximum draught, due regard should be given to unusual
tidal or environmental conditions that may affect water depth.

operation where there are restrictions on berthing energy or load limits on
fendering systems. The use of deadweight as a parameter for setting ship
size limitations is not recommended because this on its own is not a
measure of size or of total weight of vessel for calculation of berthing
energies.

15.6.3 Length Overall (LOA)
ึ
This is the maximum length of the ship and may be a limiting factor when
ships have to transit locks or turn in a turning basin.

15.6.4 Other Criteria

In addition, terminals may specify further dimensional limitations, for
example:

Minimum Length Overall (LOA): This may be specified to ensure that
small ships are not too small to tie up to or lie safely alongside the
fendering at berths designed for much larger ships.

Maximum or Minimum Bow to Centre Manifold (BCM): This is
usually to ensure alignment between ship and shore manifold
connections.
Minimum Parallel Body Length Forward and Aft of the Manifold: This
is to ensure that the ship will rest against the fenders when in position
with the cargo connection made.
Maximum Beam: This is required, for example, due to restrictions
imposed by a lock, dock or river transit.
Maximum Allowable Manifold Height Above the Water: This is to
ensure that the ship can keep the cargo arms connected throughout
the discharge and at all states of the tide. At some tidal locations, it
may be necessary to disconnect the loading arms during the high
water period.
Minimum Allowable Manifold Height Above the Water: This is
required, for example, to ensure that a loaded ship can be connected
to the cargo arms. At some tidal locations, it may be necessary to
disconnect the cargo arms during the low water period.
Maximum Air Draught: This is specified to ensure that ships can pass
beneath bridges and overhead obstructions, power cables etc. The
local harbour authority may define a minimum safe clearance distance.
