July 2012www.marinelink.com 31At the same time, the IMO has issued guidelines for bio-fouling control to minimize the spread of aquatic inva- sive species. Australia and New Zealand are revising the ANZECC code which regulates the use of antifouling systems and in-water cleaning in those countries. Cali- fornia has legislation on the way regarding biofouling with a view to preventing bioinvasions via hull fouling into the State. Others are following. The IMO is working on a Polar Code and is under pres- sure, quite correctly, to ban the use of biocidal antifoul- ing paint in the polar regions. We already have a mature non-toxic hull protection and biofouling control system which is certified for use on ice-going vessels and has been in successful commercial use for a number of years. We feel it is the best non-toxic approach to fouling control on ships and boats. We con- tinue to streamline the application and in-water mainte- nance of this coating system.Another factor which is not necessarily a legislative mat- ter but is a hot topic with class, is extending the drydock interval. The greatest obstacle to a 10-year drydock in- terval or even a 7.5-year interval is biofouling control. Because Ecospeed is maintained in the water for the life of the vessel after initial application and requires only minimal touch-ups of mechanical damage when the ves- sel does go to drydock, we predict a 10 or even 12 year interval as being well within the capabilities of our un- derwater hull protection and fouling control system. Specifically, what is your company?s offering/response in regards to the emerging rules under the PSPC (Perfor- mance Standard for Protective Coatings) for Cargo Oil Tanks (COT), which goes into effect at the start of 2013? Jim Brown, Marketing Development Manager, International Paint PSPC is an area in which we?ve been very active. All of the International Paint principal anticorrosive primers and shop primers have passed the demanding IMO PSPC COT laboratory tests in accordance with the IMO regu- lations. These regulations are designed to ensure the longevity of cargo oil tanks and stipulate that applied coatings must remain in ?good? condition for a minimum of 15 years, as defined by the International Association of Classification Societies. For a cargo oil tank coating to comply, it must be tested by Class Society approved testing facilities and have a Class Society Type Approval Certificate (TAC). The award of a TAC means the prod- uct has demonstrated the expected in service perform- ance, the quality of the supplied material is assured andthe product supply location has met regulatory require- ments. While the IP products passing laboratory tests includekey products from the Interbond, Intergard and Interplate product ranges, our premium product offer for corrosion protection in crude oil tanks is Intershield 300, a unique,abrasion resistant aluminium pure epoxy coating. Ear- lier this year, Intershield 300 demonstrated its durabil- ity after 15 years in the cargo oil tanks of the ?Samco Raven?. The 301,653 dwt crude oil tanker, underwent her third special survey at Yiu Lian Dockyard in China. The ships superintendent said that after 15 years, thecoating was in very good condition with the tanktops in excellent condition with very few areas of breakdown. Intershield 300 was also the first anticorrosive coating to be awarded type approval for seawater ballast tanks and in 2010 performance was proven in service over 15 years at the third special survey of the 73,222 dwt pana- max bulk carrier ?Eleranta?, when a Lloyd?s Register sur- veyor confirmed the double bottom tanks of the vessel to be in ?good condition.? The bulk carrier, built at Sam- sung in 1995, had Intershield 300 applied to her ballasttanks when it was built. Visser, PPG Our company is closely following the development and introduction of new rules. Our standard epoxy coating systems for the Cargo Oil Tanks of Crude Oil Tankers have been tested at a third-party laboratory according to the new IMO PSPC COT test standards. Our coating sys- tems have passed the stringent test criteria and are now offered to major Classification Societies for IMO PSPC type approval. Importantly, we can also offer advice and training, as and when required, to our customers on thecontent of these rules and their implications.Luna, HempelHempel is ready for the IMO PSPC for cargo oil tanks. The epoxy cargo oil tank coating HEMPADUR 15600, epoxy coatings HEMPADUR QUATTRO 17634 & HEMPADUR UNIQ 47741 and HEMPEL?S SHOP- PRIMER ZS 15890 have in February succeeded in pass- ing the laboratory test criteria in accordance with the new IMO resolution MSC.288(87) Performance Standard forProtective Coatings (PSPC) for cargo oil tanks of crude oil tankers. Also almost our whole range of epoxy, phe- nolic epoxy and solvent-free phenolic epoxy tank coat- ing products has undergone external testing and in June it was confirmed that HEMPADUR 15400, HEMPADUR 15500, HEMPADUR 85671, HEMPADUR 35760 and HEMPADUR 35900 all have succeeded in passing the laboratory test criteria in ac-cordance with the new IMO resolution MSC.288(87) Performance Standard for Protective Coatings (PSPC) for cargo oil tanks of crude oil tankers. Recently, several marine coatings companies have di- rectly linked the use of coatings to quantifiable fuel sav- ing on ships. Some even offering ?guarantees.? Specifically, can you/do you make such performance claims, and if so, could you please elaborate on the sys- tems you tout and studies to support. Doyle, NACE NACE International believes that it is beneficial for the marine industry to reduce and monitor the hull resist-ance. The development of new hull coating systems over the last ten + years can be an important step forward in helping the industry meet GHG emission reduction re-quirements. Van Rompay, Hydrex Yes we definitely do make such claims. In fact, it?s pos- sible that we began this trend with the publication of our series of Hydrex White Papers on ship hull performance, all publicly available free at www.shiphullperfor- mance.org. It is important to stress right up front thatEcospeed is a coating system which must be standardlyapplied and implemented in order to get the results weclaim for it. Sloppy application and failure to maintain the hull will, not unexpectedly, fail to get the expected results.
