The Guidelines for the design and construction of offshore supply vessels were adopted by the Assembly
of the Organization in 1981 by resolution A.469(XII).
These Guidelines included guidance on intact stability that was later incorporated into the Code on Intact
Stability for all Types of Ships covered by IMO Instruments. To take account of the adoption of this Code
and amendments to the SOLAS Convention that have entered into force after 1981, new Guidelines for
the design and construction of offshore supply vessels were adopted in 2006. These new Guidelines also
include a form of Document of Compliance for offshore supply vessels.
