High Level Panel on Double Hull Tankers
5 April 2005 Marpol Annex I concerning
mandatory phasing out of single hull tankers
came into force;
10
- i.e. phasing in of double hull tankers.
High Level Panel on Double Hull Tankers
Are double hull tankers the answer ?
11
High Level Panel on Double Hull Tankers
Yes, provided the double hull tanker is:
• Maintained to a high standard;
• Operated by personnel who are well trained
and committed to their jobs;
• Designed and built to high standards.
12
High Level Panel on Double Hull Tankers
Main advantage of the double hull
construction:
13
• Low energy collisions;
• Minor groundings.
High Level Panel on Double Hull Tankers
• Established April 2004;
• 6 meetings held; concluding meeting on 31st
March 2005.

• European Maritime Safety Agency (EMSA);
• International Association of Classification Societies
(IACS);
• International Chamber of Shipping (ICS);
• International Maritime Organisation (IMO);

15
High Level Panel on Double Hull Tankers
Terms of Reference
1. Scope:
To collect and analyse feedback from experience
in the design, construction, operation,
maintenance and survey of double hull
tankers of all types and sizes and identify
factors that may have an adverse impact on
the structural integrity of the vessels.
16
High Level Panel on Double Hull Tankers
Terms of Reference
2. Objective:
To produce a concise summary report that proposes
solutions for any areas of concern that the panel has
identified together with recommendations for action.
The report should also suggest methods by which its
proposals may be implemented and this may include:
2.1 Amendments to IMO requirements;
2.2 Amendments to Classification rules;
2.3 Improved guidelines for Industry;
2.4 Enhanced ‘in-service’ maintenance;
2.5 Research.
17
High Level Panel on Double Hull Tankers
Areas for consideration:
1. Accelerated structural corrosion in water ballast and
cargo tanks;
2. The lack of mandatory provisions relating to coatings
for cargo and ballast tanks;
3. Fatigue;
4. A demanding and difficult maintenance regime which, if
not properly observed could lead to structural
deterioration;
5. Lack of an international standard and of procedures to
monitor/control workmanship during the vessel new
building stage;
18
High Level Panel on Double Hull Tankers
Areas for consideration:
6. Lack of an international standard and of
procedures to monitor/control workmanship
during vessel repairs;
7. Inconsistencies between Classification
Societies in their approach to inspection and
survey – during newbuilding and during
repairs on vessels in service;
8. Possible use of inert gas in ballast spaces;
9. Hydrocarbon gas detection in ballast spaces;
19
High Level Panel on Double Hull Tankers
Areas for consideration:
10. Alignment (misalignment) between
structural members (may lead to failures in
service);
11. Structural geometry and member
thicknesses;
12. Access for structural surveys in service;
13. Robust designs and fitness for purpose;
14. Corrosion margins on newbuild hull
structural elements.
20
High Level Panel on Double Hull Tankers
Recommendations:
1. Concern: Corrosion in ballast tanks.
Control measure: Improved coating performance.
Implementation: SOLAS Reg II-I/3-2 should be
amended to introduce a mandatory performance
standard (target life 15 years) for the coatings that are
required in the ballast tanks of new double hull oil
tankers of 150m and above. The performance standard
that is currently being proposed for the ballast tanks of
Bulk Carriers would be a suitable standard to mandate.
21
High Level Panel on Double Hull Tankers
Recommendations:
2. Concern: Corrosion in cargo tanks; tank top and
deckhead.
Control measure: Coating of these two areas.
Implementation: SOLAS Reg II-1/3 should be
amended, with the possible addition of a new reg 3-7 to
mandate additional corrosion protection (coatings) for
the internal deckhead and tank top areas of cargo tanks
in newbuild tankers of 150m in length and above.
Exemption to be possible.
22
High Level Panel on Double Hull Tankers
Recommendations:
3. Concern: Corrosion in cargo tanks.
Control measure: Performance standard for cargo
tank coatings.
Implementation: SOLAS Reg II-I/3 should be
amended to introduce a mandatory performance
standard (coating life) for the coatings that are
recommended (in this report) for the cargo tanks of
new double hull oil tankers of 150m and above. IACS
may develop this standard with Industry by means of
the joint working group on corrosion.
23
High Level Panel on Double Hull Tankers
Recommendations:
4. Concern: Corrosion in ballast or cargo tanks.
Control measure: Repair and maintain coating.
Recommendation: it is recommended that vessel
owners repair and maintain the tank coating systems
on their vessels in accordance with the coating repair
standard that has been developed by IACS (Guidelines
for coating maintenance and repairs for ballast tanks
and combined cargo/ballast tanks on oil tankers). The
repair standard may be referenced within the proposed
TSCF maintenance manual.
24
High Level Panel on Double Hull Tankers
Recommendations:
5. Concern: Cracks due to fatigue.
Control measure: An appropriate response to fatigue
failures to be developed that includes fatigue analysis
when appropriate and pro-active repairs or
modifications as may be necessary.
Implementation: IACS to develop guidance for
identifying significant failures caused by fatigue and
procedures to be followed when dealing with such
identified cases. Revisions to IMO Resolution A.744(18)
should also be considered.
25
High Level Panel on Double Hull Tankers
Recommendations:
6. Concern: Variations in workmanship and construction
standards during new building and during repairs.
Control measures: Establish international standards
for hull construction, including TSCF recommendations
for repairs. Harmonize the content, standards and
procedures of the initial hull Classification survey.
Harmonize the content and standards of initial statutory
surveys. Establish and harmonize standards for hull
repairs on existing vessels.
Implementation: IACS to develop standards,
procedures and requirements that will enable the
harmonization of newbuild Classification surveys (with a
view to issuing as Unified Requirement). Modifications
to IMO Resolution A.948(23) should be considered to
improve initial statutory surveys.
26
High Level Panel on Double Hull Tankers
Recommendations:
7. Concern: Cargo seepage into ballast tanks.
Control measure: Fixed hydrocarbon gas detection
system to be provided within double hull and double
bottom spaces of tankers to allow constant monitoring
of tank atmospheres.
Implementation: SOLAS Reg II-I/5.7 to be amended
to require that fixed hydrocarbon gas detection
systems, giving constant monitoring of double hull and
double bottom tank atmospheres, are made mandatory
in new tankers; only on those vessels required to be
provided with an inert gas system in the cargo tanks:
20000 DWT and above or using crude oil washing.
27
High Level Panel on Double Hull Tankers
Recommendations:
8. Concern: Cargo seepage into ballast tanks.
Recommendation: The owners and operators of
existing double hulled taners should be encouraged to
consider fitting fixed hydrocarbon gas detection
systems within the double hull and double bottom
spaces of their vessels.
IACS to establish standards and requirements for a
suitable fixed hydrocarbon gas detection system
(possibly by means of a joint working group with
Industry).
28
High Level Panel on Double Hull Tankers
Recommendations:
• 9. Concern: Corrosin and fatigue in ballast and cargo
tanks
Control measure: Hull maintenance
Implementation: Appropriate procedures and
standards for repairs and maintenance need to be
established.
(possibly the new TSCF maintenance manual could be
means by which this could be introduced; as an IMO
resolution or linked to Classification).
29
High Level Panel on Double Hull Tankers
• The recommendations to be implemented through:
• 1. Amendments to IMO Conventions
• 2. Amendments to classification requirements and
procedures
• 3. Improved guidelines and self regulation by Industry
• Final report expected to be approved by the Panel June
2005
• Benchmark meeting in autumn 2005 to assess progress
made in implementation of recommendations and the
Maintenance Manual from TSCF
