1 MarineLINE (Siloxirane) Coating for Ships Engaged in the Carriage of Edible Oils and Chemicals Presented to FOSFA International August 10, 2004 By Donald J. Keehan

2 Cargo Versatility - Can Carry Virtually All IMO Cargoes Carry More Cargoes than Stainless Steel Clean Tanks Faster than Stainless Steel Tanks or Other types of Coated Tanks MarineLINE

3 Resists More Chemicals than Stainless Steel and Other Coatings Resistance to 131 Most Carried Chemical Cargoes MarineLINE

4 Market Limitations Prior to MarineLine Problems with Zinc Silicate Coatings Absorbs Cargo Quickly Retains Oil Like Cargoes Subsequent Cargo Contamination Limit Back Hauling Capability Not Resistant to Acids, Caustics, and Acid Containing Oils and Urea MarineLINE

5 Market Limitations Prior to MarineLine Problems with Phenolic Epoxy Coating Absorbs Cargoes to High Levels (depending on cargo) Absorbs Cargo Relatively Slowly Releases Absorbed Cargo Very Slowly Small Traces May be Retained Subsequent Cargo Contamination MarineLINE

6 Epoxies 3-dimensional screen-like structure when polymerized The greater the distance between crosslinks the greater the permeation causing chemical attack and absorption Epoxies used in coatings have Two (2) Functional Groups per molecule giving Four (4) Crosslinks Limitation of Epoxy Coatings MarineLINE

7 28 Functionality vs. Epoxy 2 Functionality in same area: 784 crosslinks vs. 4 crosslinks Higher Functionality Produces Higher Crosslink Density... Giving: Higher Chemical Resistance Higher Temperature Resistance Resistance to Permeation (absorption) MarineLINE

8 Epoxys Open Screen Structure MarineLine 784s Closed Screen Structure MarineLine vs. Phenol Epoxy MarineLINE

9 MarineLINE is approximately 3 times smoother than Phenol Epoxies and over 4 Times smoother than Stainless Steel (as confirmed by Independent Laboratory) MarineLINE Ra Phenol EpoxyRa Stainless SteelRa MarineLINE The Technology behind Easier Cleaning

10 Surface Energy / Surface Tension MarineLINE is Over 40 Times More Slippery than Stainless Steel and almost 5 times Slipperier than Phenol Epoxies Surface Energy is measured in Dynes/cm * Source: N.K. Adams The Physics and Chemistry of Surfaces MarineLINE The Technology Behind Easier Cleaning

11 Chemical Resistance Non Absorbent Qualities Verified Independent Test Certified by Members of International Association of Classification Societies (IACS) MarineLINE

12 % Absorption After 45 Days Immersion Days Recovery (Desorption) with 30°C Test by Independent Testing Laboratory MarineLine vs. Phenolic Epoxy MarineLINE

13 MarineLine vs. Phenolic Epoxy % Absorption after 45 days Days Recovery (Desorption) with Ventilation at 30 o C. Test by Independent Testing Laboratory MarineLINE

14 MarineLine vs. Phenolic Epoxy % Absorption after 45 days Days Recovery (Desorption) with Ventilation at 30 o C. Test by Independent Testing Laboratory MarineLINE

15 Test Protocol: 1) 3 Steel Boxes Coated With MarineLine and Bottoms Reinforced With Fiberglass Impregnated With MarineLine Resin - Boxes Blasted and Coated Inside Cargo Tanks of M/T Joran - Boxes Cured in Oven at 80°C for 6 Hours All Tests Witnessed and Certified by DNV Italy and RINA Laboratorio Chimico Merceologico Genoa, Italy, Dr. R. Cosulich

16 MarineLINE 2) Each Box Was Loaded With a Chemical for 30 Days. Chemicals Tested: 80% Acetic Acid 50% Phosphoric Acid Methanol 96% Sulfuric Acid Ethylene Dichloride Caustic Soda Virgin Naphtha Premium Gasoline All Tests Witnessed and Certified by DNV Italy and RINA Laboratorio Chimico Merceologico Genoa, Italy, Dr. R. Cosulich

17 MarineLINE 3) After 30 Days, the Boxes Were Emptied. Coated and Lined Surfaces Were Checked for Chemical Attack. 4) Each Chemical Was Checked for Contamination From Previous Chemical or MarineLine Coating. 5) Boxes Were Washed With Salt and Fresh Water Before Loading With Next Chemical. 6) MarineLine Coating Was Washed With Methanol & Analyzed for Chemical Residual. All Tests Witnessed and Certified by DNV Italy and RINA Laboratorio Chimico Merceologico Genoa, Italy, Dr. R. Cosulich

18 Product Purity (Non-Contamination) Before & After 30 day Immersion Product Tested MarineLINE Test Certified by DNV and RINA

19 Wall Wash Methanol Analysis (non-absorption) Before and After 30 Day Immersion MarineLINE Test Certified by DNV and RINA

20 MarineLINE Siloxirane Coating Approved for Food and Potable Water

21 Siloxirane Coating MarineLINE

22 Tanker Operators Statements MarineLINE " It was found that conventional intensive cleaning methods used for Zinc and Epoxy coated tanks does not have much effect on MarineLine coating. MarineLine coated tanks can be cleaned quicker in the same way as cleaning stainless steel tanks. Rust remover and caustic based detergents used to spray and scrub were used to scrub and remove dried up patches of sulphur after Sulphured Gas Oil last cargo. After this simple cleaning the tank can be made ready for methanol and MEG (methanol wall wash standard) cargoes quickly." Capt. Ramu Naidu Aurora Tankers M/T Selendang Sari

23 Tanker Operators Statements MarineLINE Mr. Jan Slooter, MD Clearwater Group M/T Coralwater changes cargoes on weekly basis. As an example ships 5 P/S had 7 different cargoes over 7 week period. Sequence of cargoes, spent caustic, nitrobenzene, epichlorohydrin, acryonitrile, EDC, analine, and formaldehyde. Prior to unloading sample of each cargo was taken for test and verification on non-contamination. After each unloading tanks were washed with hot salt water, followed by fresh water wash. Tanks were certified clean by methanol wall wash test prior to loading next cargo. Over 5-year period M/T Coralwater has never had a cargo contamination claim. Ship has carried over 400 different cargoes. Our MarineLine coated ships clean easier and faster than our older stainless steel ships.

24 MarineLINE Hernings MarineLine coated M/T Serra Theresa is carrying French Cognac to Ukraine and Ethyl Alcohol on return voyages.

25 MarineLINE Over 50 MarineLine coated ships operating since 1994 without a contamination claim Additional 60 tankers contracted for MarineLine coating by 2007
