The 2011 ESP Code became mandatory under
SOLAS regulation XI-1/2. Parts A and B of annex A of
the Code provide the requirements for bulk carriers
with single-side skin and double-side skin construction, respectively. Parts A and B of annex B of
the Code provide the requirements for oil tankers with double-hull and non-double-hull construction,
respectively. In order to provide an easy-to-use Code, IMO’s Maritime Safety Committee agreed that
the Code should be closely aligned with the IACS Unified Requirements (UR) Z10 (Hull surveys).
