  1. Intershield®300 60% of the world’s LNG carriers are protected by Intershield®300 – the industry benchmark in corrosion protection

  2. Intershield®300 • Overview • Features & Benefits • Technology Background • Proven In-service Performance • Track Record

  3. Intershield®300 - Overview • Intershield®300 the LNGc industry operators’ choice for high performance, long term asset protection. • Introduced in 1988, Intershield®300 can be used as a universal primer at Newbuilding or Maintenance & Repair. • This unique abrasion resistant, (>9%) aluminium pure epoxy coating offers long term asset protection, control of through life maintenance costs and enhances vessel earning potential • Intershield®300 is a light coloured, abrasion resistant, aluminium pure epoxy coating. It can be applied directly to mechanically prepared shop primer or suitably prepared bare steel and is suitable with controlled cathodic protection

  4. Intershield®300 - Overview • 60% of the global LNGc fleet is protected by Intershield®300. • Intershield®300 has been applied to 150 LNGc vessels. • With an average vessel lifetime expectation of 40 years, the LNGc industry demands exceptionally high levels of corrosion protection. • Failure to apply adequate corrosion protection at Newbuilding leads to additional costs to LNGc owners and operators during the vessel lifespan • Many LNGc owners and operators recognise the importance of using the highest level of protection available and are taking advantage of the performance of Intershield®300

  5. Intershield®300 - Overview • The basic concept of a Universal Primer is to simplify block painting procedures • Replacement of several products with a single product that meets all the required characteristics that the shipyard demands. • Intershield®300 is has excellent application properties and low temperature cure so it can provide the same ultimate protection through all seasons • Intershield®300 can ensure all areas of your LNGc are protected by the ultimate corrosion protection.

  6. Intershield®300 – Features & Benefits

  7. Intershield®300 – Corrosion Resistance • Due to the emergence of new supply and importing markets trade routes for LNG carriers are becoming more diverse. • In ballast tanks, for every 10oC increase in ballast water temperature the rate of corrosion doubles - increasing the requirement for a higher performance anticorrosive. • Cycling between hot and cool water also increases the internal stresses within coatings and so crack resistance becomes imperative. • Export Countries • Qatar, Australia, Yemen, Nigeria, Peru, Angola, Norway, Russia… • Import Regions • Europe, Americas, • Asia

  8. At the core of a sound hull structure is the requirement to maintain the ballast tank anticorrosive system. By specifying Intershield®300, LNGc owners and operators can reduce maintenance, repair and touch-up costs, steel replacements and time in dock. In service inspections of Intershield®300 give evidence that it delivers long term asset protection and return on investment. Due to the complexity of water ballast tanks – its is difficult for the applicator to ensure that the correct dry film thickness is applied to all vessel areas - Intershield®300 performs excellently at both high and low dry film thicknesses. Intershield®300 – Corrosion Resistance Modified Epoxy – 7 years in Service Intershield®300 – 7 years in Service Intershield®300 – 15 years in Service

  9. Intershield®300 – Corrosion Resistance • Corrosion and general fatigue increase as LNGc age • Many LNG vessels are built using high tensile steel as it allows the use of thinner plates whilst maintaining structural integrity. • High tensile steel corrodes just as quickly as mild steel – and is a concern because there is less steel to corrode before a resultant failure / leak takes place. • Intershield®300 is designed for the ultimate long-term corrosion protection to minimize maintenance expenses and maximize long-term asset protection

  10. Intershield®300 – Aluminium Pigmentation • Aluminium acts both as a barrier pigment and to prevent the spread of corrosion at the steel surface (reduction in underfilm creep) • The maximum allowable level by class societies for aluminium (in the dry film) is 10% by weight • Intershield®300 contains just the right levels of aluminium (>9% by weight in the dry film) to ensure it is safe and compliant • Also offers improved resistance to cathodicdisbonding – providing corrosion protection from Newbuilding through the lifetime of the vessel

  11. Intershield®300 – Edge Retention • Due to the complexity of water ballast tanks, edge protection is critical - yet many coatings start to fail on edges, exposing the steel and leading to corrosion. • Stripe coating helps but the best solution is to use a coating that utilizes “edge retentive” properties • Intershield®300 performs excellently on edges giving the owner long term corrosion protection - even on the most demanding vessel areas. Typical Modified Epoxy < 40% Intershield®300 = 100%

  12. Intershield®300 – Technical Expertise • Our globally available, highly trained technical service team means that we can provide a service beyond paint delivery and can give sound technical advice to support the lifespan of your LNGc vessel • Our worldwide technical service training program is recognized by Classification Societies as equivalent to NACE and FROSIO qualifications and meets the requirements of IMO Resolution MSC.215(82) – Performance Standard for Protective Coatings (PSPC) • Globally International Paint has over 800 TSRs, 260 qualified to NACE standards and 105 FROSIO Inspector Level III or equivalent – as verified by the administration.

  27. IMO PSPC standardizes the coating process to ensure ballast tank coatings have a target lifetime of 15 years but it can’t guarantee approved coatings will last this long. Many WBT coatings will achieve 15 years, but will require varying amounts of repair through their life - costing money and time. As LNG vessels are designed and built for a 40 year lifetime, selection of a high performance coating that has proven long-in service performance is wise. Intershield®300 is the industry benchmark in IMO PSPC compliant anticorrosive performance and has an extensive proven track record Intershield®300 – Beyond Compliance Modified Epoxy Pure Epoxy P E R F O R M A N C E Aluminium Pure Epoxy Abrasion Resistant Aluminium Pure Epoxy

  28. Intershield®300 – Beyond Compliance • The IMO PSPC for Water Ballast Tanks states that protective coatings must have a 15 year lifetime in dedicated seawater ballast tanks •  At her third special survey a Lloyd’s Register surveyor confirmed the double bottom tank coatings of the panamax bulk carrier, the m/v Eleranta to be in “good” condition (as rated in IACS Recommendation 87) • Intershield®300 is the only anticorrosive on the market that has proven 15 years in service performance • With minimal maintenance and repair, it is expected that Intershield®300 will continue to protect the ballast tanks of the m/v Eleranta; exceeding IMO PSPC standards and going beyond compliance.
