Class and Statutory aspects of conversions and refurbishment <Arnstein Eknes> <Mariehamn, 12 October 2006> On the agenda today Starting point for all conversions What is minor / major conversion Statutory Examples Summary - Key questions to address early and repeatedly! Slide 2 1
Planning Know the purpose with conversion - and what is major Slide 3 Plan your conversion What is the purpose with the conversion - Describe as early as possible Proper planning pay off later - Reduce risk of delays, extra work & late suprises - Part of planning is knowing the regulatory consequences - Early identification of critical focus areas - Establish responsibility for important key tasks early Slide 4 2
Plan your conversion Typical early questions to address: - Will the ship be engaged in different trade than before the conversion? - Will any of the ship certificates be affected - Do we know what require approval and by whom? When looking at solutions: - What is possible - What are the consequences on function & process & cost When planning the process: - What should be prepared & approved prior to construction? Slide 5 Major conversion - definition By modifications of a major character it is to be understood that major conversions are defined as a conversion of an existing ship: i) which substantially alters the dimensions or carrying capacity of the ship; or ii) which changes the type of ship; or iii) the intent of which in the opinion of the Society substantially prolongs the life of the ship. (MARPOL 73/78, Annex I, Regulation 1(8)(a)) Slide 6 3
Major conversion i) which substantially alters the dimensions or carrying capacity of the ship; Slide 7 Major conversion ii) which changes the type of ship; Stern Trawler Seismographic vessel Slide 8 4
Major conversion iii) the intent of which in the opinion of the Society substantially prolongs the life of the ship. Example: Renewal of passenger accommodation on one entire deck on a passenger ship. The renewed accommodation is to comply with current rules. Slide 9 Application of rules Fire safety Modifications in connection with a major conversion shall comply with current rules. Notwithstanding passenger ships w. > 36 passengers shall comply with the following (SOLAS Ch.II-2 Reg1.3.2): a) all new material shall comply with current rules. Slide 10 5
Application of rules Fire safety ( > 36 passengers.. (SOLAS Ch.II-2 Reg1.3.2)) : b) When 50 t new interior material; systems and interior arrangement shall comply with current requirements. DNV interpretation : 50 t per deck. USCG interpretation: 50 t per Main Fire Zone. Slide 11 Can the draught be increased? Initial questions will include: What is scantling draught and which draughts have been approved earlier? Has the question been raised before for this ship or sister ships? Will there be any redefinition of the freeboard deck? Will it be feasible to meet load line regulations? Will it meet current (or new) stability requirements? Global strength Bow height requirements Stern-, bow- or side doors Position of side scuttles, valves and discharges Rudder system Maintain ice class after conversion? Next step: start calculations.

Rules and regulations Classification IACS Unified Requirements Validity / edition - Date of class request / date of contract between builder and owner for new ship Classification principles - New rules prevail - Grandfather clause? Statutory Statutory regulations Validity / edition - Keel laying date important Statutory principles - Existing regulations valid for existing ships - Flag - Ports New regulations for new ships - Unless clearly specified Slide 17 Applicable statutory regulations SOLAS Ch. II-1 - Increase in number of passengers, added / relocated weights may affect stability calculations and imply new inclining test SOLAS Ch. II-2 - Re-arrangement of stairs & corridors and accesses to escape ways are critical as well as changing the function of a space may require re-categorisation of spaces. Slide 18 9
Applicable statutory regulations SOLAS Ch. III - New and relocated lifesaving equipment shall always follow latest SOLAS amendments. - Lifesaving equipment in new positions will require fire integrity of ship side / protection of windows - This may be extensive work, class A requirements for post October 2004 ships, class B requirements for pre October 2004 ships Slide 19 - Main Vertical Fire Zone Structural Fire Subdivision Passenger Ships ~40 m (max 48 m) A-60 A-60 A-60 Area Max =1600 m 2 (1600/48 =33.33 m) 10

Examples showing importance of proper planning Slide 27 Examples Hotel manager ordered, without any preapproval from own shore based offices nor Class or Flag, contractors to re-arrange pantry & restaurant spaces, including new direct accesses to staircases and closing excisting escape corridors. Consequence was impairment of staircase boundaries and blocking of mandatory escape routes Slide 28 14
Examples Owner decided to install new sewage handling system while in operation, work started without any further clarification with Class or Flag. Consequence was that water tight bulkheads and structrual elements where cut open by subcontractors damage stability properties seriously impaired Slide 29 Examples -Current Statutory Certificates and i.e. vessel arrangements may be based on numerous exemptions / operational limitations - Vital to have the PSSC & exemption certificates, List of Operational Limitations as well as latest stability booklets, damage control plan, fire and life saving plans (including the approval letters from Flag State / RO, not only the stamped documents) Slide 30 15
Examples Older vessels taken from a domestic trade or fixed route between two neighbouring ports are traditionally not up to SOLAS compliance for international trade. Inability of current Owner to provide upfront the key documents referred to traditionally confirm sub- SOLAS standard and need for significant upgrades if international trade with PSSC is the target. - Acceptance by new Flag may be a challenge Slide 31 Summary Conversion and refurbishment Slide 32 16
Critical for successful processes Early involvement! Kick off meeting incl. class - Exchange information - Be clear on responsibility - Discuss purpose of conversion - Discuss possible solutions - Early identification of regulatory impact, DNV can advise 18 October 2006 Mariehamn Slide 33 Critical for successful processes Early involvement! Kick off meeting incl. class - Agree upon - rule interpretations - a drawing approval schedule - Identify and discuss possible problem areas - Agree upon the required documentation scope for submittal - target: planning & approval before construction Mariehamn 18 October 2006 Slide 34 17
