High Level Panel on Double Hull Tankers

• 5 April 2005 Marpol Annex I concerning mandatory
  phasing out of single hull tankers came into
  force
• - i.e. phasing in of double hull tankers.

11
High Level Panel on Double Hull Tankers

• Are double hull tankers the answer ?

12
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.

13
High Level Panel on Double Hull Tankers

• Main advantage of the double hull construction
• Low energy collisions
• Minor groundings.

14

• Established April 2004
• 6 meetings held concluding meeting on 31st March
  2005.

16
High Level Panel on Double Hull Tankers

• Terms of Reference
• 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.

17
High Level Panel on Double Hull Tankers

• Terms of Reference
• 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.

18
High Level Panel on Double Hull Tankers

• Areas for consideration
• Accelerated structural corrosion in water ballast
  and cargo tanks
• The lack of mandatory provisions relating to
  coatings for cargo and ballast tanks
• Fatigue
• A demanding and difficult maintenance regime
  which, if not properly observed could lead to
  structural deterioration
• Lack of an international standard and of
  procedures to monitor/control workmanship during
  the vessel new building stage

19
High Level Panel on Double Hull Tankers

• Areas for consideration
• Lack of an international standard and of
  procedures to monitor/control workmanship during
  vessel repairs
• Inconsistencies between Classification Societies
  in their approach to inspection and survey
  during newbuilding and during repairs on vessels
  in service
• Possible use of inert gas in ballast spaces
• Hydrocarbon gas detection in ballast spaces

20
High Level Panel on Double Hull Tankers

• Areas for consideration
• Alignment (misalignment) between structural
  members (may lead to failures in service)
• Structural geometry and member thicknesses
• Access for structural surveys in service
• Robust designs and fitness for purpose
• Corrosion margins on newbuild hull structural
  elements.

21
High Level Panel on Double Hull Tankers

• Recommendations
• 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.

22
High Level Panel on Double Hull Tankers

• Recommendations
• 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.

23
High Level Panel on Double Hull Tankers

• Recommendations
• 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.

24
High Level Panel on Double Hull Tankers

• Recommendations
• 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.

25
High Level Panel on Double Hull Tankers

• Recommendations
• 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.

26
High Level Panel on Double Hull Tankers

• Recommendations
• 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.

27
High Level Panel on Double Hull Tankers

• Recommendations
• 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.

28
High Level Panel on Double Hull Tankers

• Recommendations
• 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).

29
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).

30
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
