1. Intershield®300
60% of the world’s LNG carriers are protected by Intershield®300 – the industry benchmark in corrosion protection
Intershield®300 Abrasion resistant aluminium pure epoxy
The LNGc industry choice.
Operators of LNGcs demand high performance coatings to deliver long term asset protection throughout the 40 year vessel life. That’s why over 60% of the world’s LNGcs are protected by Intershield®300
Working closely with the world’s major vessel operators and new construction yards, International Paint recognised the importance of high performance corrosion protection for improved newbuilding productivity and long term asset protection.
Over 20 years after its introduction, Intershield®300 is now firmly established as the newbuilding industry benchmark for premium performance, abrasion resistant, corrosion protection.
Value Proposition: -
Intershield®300 - is available in the newbuilding and maintenance and repair sector as an integral part of an overall corrosion protection program designed to provide cradle to grave protection for the ship.
With an operational requirement for the highest levels of corrosion protection, many operators of LNG newbuildings have chosen International Paints’ Intershield®300 for just about every area of the vessel.
Intershield®300, specified and professionally applied initially at the new construction stage and then during planned maintenance throughout the vessel’s life, can offer long term asset protection, maximised operational efficiency, controlled future maintenance costs and good return on investments. Intershield®300 has built an impressive and unique track record of outstanding corrosion protection on over XXX LNG carriers worldwide.*
PSPC Into updated position –
Intershield®300 is widely recognised as the industry benchmark product in terms of IMO PSPC compliance. With its excellent anticorrosive performance, unique abrasion resistance and over 9% aluminium content, this pure epoxy coating offers asset protection beyond legislative compliance.
“In a third special survey of the 15-years-old bulk carrier, m.v. Eleranta, built in Samsung in 1995, a Lloyd’s Register surveyor confirmed the double bottom tank of the vessel coated with Intershield®300 was in “good” condition. This is the only recorded vessel that has proven to meet the IMO PSPC guidelines and it’s expected that Intershield®300 will continue to deliver excellent protection to the m.v. Eleranta further into her life.”

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
Additional Information
60% of the global LNGc fleet are protected using Intershield®300 (both at NB and M&R)
At Newbuilding 150 vessels coated with Intershield 300 (360 vessels in the fleet)
The LNG shipping industry prides itself on its long record of safe operations and with an above average vessel lifetime expectation of 40 years, the LNGc industry demands exceptionally high levels of corrosion protection.

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.

8. Intershield®300 – Corrosion Resistance
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.
Modified Epoxy – 7 years in Service
Intershield®300 – 7 years in Service
Although it is common practice for yard quality assurance personnel and owners’ representatives to focus on identifying areas of low dry film thickness, inevitably due to the complexity of these structures some areas will not achieve the specified film thickness
Low DFT is a key cause of premature corrosion in ballast tanks – Intershield 300 delivers excellent ac protection even when applied at low dft.
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 cathodic disbonding – 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

28. Intershield®300 – Beyond Compliance
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

29. 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.
