This manual offers guidelines for double hull oil tankers constructed primarily for the carriage of oil in bulk. It includes a review of survey preparation guidelines which cover safety elements and the preparations required before surveys can be carried out. The book highlights what to look for, possible causes and recommends viable repair methods.
The guidelines focus on the IACS Member Societies’ survey procedures but may also be useful in connection with survey/examination schemes of other regulatory bodies, owners and operators.
This manual has been developed using the best information currently available. It is intended only as guidance in support of the sound judgement of Surveyors, and is to be used at the Surveyors' discretion.
This book includes a review of survey preparation guidelines, which cover the safety aspects related to the performance of the survey, the necessary access facilities, and the preparation necessary before the surveys can be carried out.
The survey guidelines encompass the different main structural areas of the hull where damages have been recorded, focusing on the main features of the structural items of each area.
An important feature of the manual is the inclusion of the section which illustrates examples of structural deterioration and damages related to each structural area and gives what to look for, possible cause, and recommended repair methods, when considered appropriate.
The International Association of Classification Societies (IACS) manuals provide guidelines to assist the Surveyors of IACS Member Societies, and other interested parties, involved in the survey, assessment and repair of hull structures for certain ship types.
This
manual
gives
guidelines
for
a
double
hull
oil
tanker,
which
is
constructed
primarily
for
the
carriage
of
oil
in
bulk
and
which
has
the
cargo
tanks
protected
by
a
double
hull
that
extends
for
the
entire
length
of
the
cargo
area.
It
consists
of
double
sides
and
double
bottom
spaces
for
the
carriage
of
water
ballast
or
void
spaces.
These
guidelines
focus
on
the
IACS
Member
Societies’
survey
procedures,
but
may
also
be
useful
in
connection
with
survey/examination
schemes
of
other
regulatory
bodies,
owners
and
operators.
It
includes
a
review
of
survey
preparation
guidelines,
which
cover
the
safety
aspects
related
to
the
performance
of
the
survey,
access
facilities
and
the
preparation
necessary
before
the
surveys
can
be
carried
out.
The survey guidelines encompass the different structural areas of the hull where damages have been recorded, focusing on the main features of the structural items of each area.
An important feature of the manual is the inclusion of the section that illustrates examples of structural deterioration and damages related to each structural area. It shows what to look for, possible causes and recommended repair methods when considered appropriate.
This manual has been developed using the best information currently available. It is intended only as guidance in support of the sound judgment of Surveyors, and is to be used at the Surveyors’ discretion. It is recognised that alternative and satisfactory methods are already applied by Surveyors. Should there be any doubt with regard to interpretation or validity in connection with particular applications, clarification should be obtained from the Classification Society concerned.
Surveyors
dealing
with
single
hull
oil
tankers
should
be
encouraged
to
read
the
‘Guidance
Manual
for
Tanker
Structures’,
based
on
the
practices
of
the
Tanker
Structure
Co-operative
Forum.
IACS
Common
Structural
Rules
for
Tankers,
implemented
in
April
2006
and
updated
in
2019,
were
developed
in
response
to
a
consistent
and
persistent
call
from
industry
for
an
increased
standard
of
structural
safety.
This
was
achieved
through
enhancing
the
design
basis
and
applying
engineering
first
principles.
The
development
of
the
CSR
for
Tankers
included
review
of
existing
Rules,
new
development
using
a
first
principle
approach,
application
of
the
net
thickness
philosophy,
an
enhanced
design
environment
and
a
longer
life,
ie
25
years
North
Atlantic.
The
Rules
are
applicable
to
double
hull
oil
tankers
exceeding
a
length
of
150
metres.
Note: Throughout this document reference is made to various IACS Unified Requirements (UR), Procedural Requirements (PR) and Recommendations. All URs and PRs and key recommendations are available from the IACS website (http://www.iacs.org.uk ).

The International Chamber of Shipping (ICS) is the principal international trade association for the shipping industry, representing shipowners and operators in all sectors and trades.
ICS membership comprises national shipowners' associations in Asia, Europe and the Americas whose member shipping companies operate over 80% of the world's merchant tonnage.
Established in 1921, ICS is concerned with all technical, legal, employment affairs and policy issues that may affect international shipping.
ICS represents shipowners with the various intergovernmental regulatory bodies that impact on shipping, including the International Maritime Organization.
ICS also develops best practices and guidance, including a wide range of publications and free resources that are used by ship operators globally.
