3 WHO WE ARE Vard Marine Inc. is a naval architecture and marine engineering company established in July 1983 and is a subsidiary of VARD Group AS in Norway. Its offices stretch across North America to: Vancouver, BC Houston, TX Ottawa, ON Page 3

4 HISTORY OF VARD MARINE INC STX Canada and US Marine Purchased by VARD Name changed to STX Canada and US Marine Inc. after acquisition by the STX Group Wartsila Arctic Office opens in Vancouver Opened US office in Annapolis, MD Name changed to Wartsila Marine Inc, Relocated US operation to Houston, TX Name changed to Aker Marine, Inc Name change to Kvaerner Masa Marine Acquired Polar Design Associates formerly Cleaver & Walkingshaw Name changed to Aker Yards Marine, Inc Opened new Canadian office in Ottawa, ON 2013 Opened new office in North Vancouver Page 4

8 Aker Arctic Value Added Support with hull form development & propulsion system selection Model testing Structural concepts And data Examples focus on recent Canadian Navy Arctic patrol ship Coast Guard polar icebreaker designs 3/9/2016 Page 8

9 Data Ice engineering remains a very empirical discipline Purely theoretical models need to be treated with extreme caution Aker Arctic has an unparalleled database of model testing, full scale data and service experience, together with a library of 3 rd party information. It is extremely valuable to VARD, and to our clients, to use this data to gain confidence in performance predictions at all stages of a project. Understanding knowledge gaps is also key to the design development strategy Concept exploration Model test scope etc 3/9/2016 Page 9

10 Hull form development Most icebreaking hull forms involve multiple trade-offs: Icebreaking and open water resistance Seakeeping and manoeuvrability Performance and construction cost Arctic Offshore Patrol Ship: Modest icebreaking requirement (1m) Extensive open water operations Considerable design to cost constraint Polar Icebreaker High end icebreaking requirement (2.5m) High endurance Multi-mission; extensive science missions 3/9/2016 Page 10

11 Aker Arctic support hull form AOPS Lines plan finalization Propulsion system trade-offs (pod/shaft) Input to model test plans Polar Exploration and analysis of multiple hull forms (straight, sloped, knuckled sides, etc) Highly customized bow form development Analysis and assessment of multiple propulsor configurations (shafts, nozzles, pods) Input to model test plans; and testing 3/9/2016 Page 11

12 Model testing considerations Ice model testing is expensive, but is critically important to performance verification and hull form finalization 1. Issues with ice tank testing can include: a) Inherent ice properties (strengths, density, etc) b) Consistency between and within ice sheets c) Model-ice friction coefficients d) Realistic propulsor models 2. Model-full scale correlation a) Resistance scaling b) Propulsive effects (prop-ice interaction) c) Correlation with full-scale trials results 3. Interpretation of results The testing organization needs to provide: Quality in (1) Value-added in (2) and (3) 3/9/2016 Page 12

13 Aker Arctic support model testing In AOPS and Polar icebreaker, Canadian government policy dictated that initial tank testing should take place in St. John s Newfoundland, at National Research Council Tank. AAT support was crucial in assessing initial results and identifying ways ahead. Additional testing of Polar was conducted at AAT to verify and validate performance. All of this drew heavily on past data and staff experience. 3/9/2016 Page 13

14 Structural concepts Selection of basic ice class needs to match concept of operations where, when, what? Ice classes are generic - tailoring may be needed to address real operational risk. Classification society rules (and IACS URs) do not provide comprehensive methodologies for selection, customization, or for the design of many components. Analysis can help, but real-world data and experience are even more important 3/9/2016 Page 14
