International
Load Line Convention 1966 (ILLC) Simplified.
International
LoadLine Convention is a IMO convention adopted on 5th
April 1966 and entered in to force on 21st July 1968.
Why ILLC?
(The Purpose)
The
ILLC aims to establish uniform principles and rules with respect to
limits which the ships engaged in international voyages may be loaded
having regard to safeguarding life and property at sea.
Brief
history.
The
first LoadLine convention was adopted in 1930 based on the principle
of reserve buoyancy. It was also recognised that adaquate freeboard
ensures stability and to avoid excessive hull stresses due to
overloading.
The
ILLC 1966 have taken into account the freeboard by sub division and
damage stability conditions.
The
Structure of ILLC
The
ILLC has 3 annexes. Annex 1 is further divided in to 4 chapters.

Loadline
ammendments that never came into force.
Various
ammendments were adopted in years 1971, 1975, 1979 & 1983. They
required positive acceptance of two thirds of the parties involved.
This has not been reached, therefore never came into force.
So, What is
TACIT Ammenndment procedure?
As
you have read above, it takes a long time an ammendment to come into
force by positive acceptance. In order to speed up this procedure,
TACIT ammendment procedure was introduced which was included in 1988
protocol.
How does the
tacit ammendment procedure work?
By
tacit ammendment procedure an ammendment adopted to the International
LoadLine Convention will enter into force 6 months after the deemed
date of acceptance unless one third of the parties reject it.
Usually
the duration from the date of adoption to date deemed acceptance is 2
years.
What
happened to the 1995 ammendments?
The
1995 ammendments was adopted under the possitive acceptance method
-did not enter into force were superseeded by 2003 ammendments.
2003
ammendments were adopted in June 2003 entered into force in 01st
Jan 2005.
