Istanbul, Turkey, April 18, 2006 – When Turkey-based KS Shipping decided to add a line of five newbuild chemical tankers to its fleet, they required a novel protective tank lining system for ultra-demanding performance. USA-based Advanced Polymer Coatings (APC) presented a new MarineLine®-based lining and coating system to ensure the KS ships could carry the maximum types of cargoes possible by providing superior resistance to a wide of chemicals including acids and also have the added strength to withstand basic mechanical damage.

The fleet of five 15,300 dwt ships goes beyond typical classification expectations. Key engineering specifications outline the requirement that the tanks be able to carry acids with a Specific Gravity of up to 1.9 and meet all IMO ll specifications. In addition, a key specification is that a barrier be installed in order to prevent mechanical damage to the tank tops. Each of the ships contains 18 cargo tank and two slop tanks.


MarineLine® was chosen as the coating for its proven performance in many years of service in the chemical tanker industry, and its versatility in handling the IBC cargo range. To answer the need for the mechanical barrier, a special MarineLine®-impregnated fiberglass-reinforced matting system was developed to cover and protect the tank tops and bulkheads. The fiberglass-reinforced lining measures approximately 95-130mm thick, providing exceptionally high tolerance to mechanical damage (more than 10 times greater impact resistance than the coating alone).

All the newbuild construction has been at Cicek Shipyard in Turkey. On the first ship done, the M/T Puli, the tank lining system began with a MarineLine® coating applied in two spray coats to the deckhead and bulkheads. A MarineLine® base coating was applied to the tank tops. This area was then wetted out with MarineLine® fiberglass rolled into the resin. Next, the fiberglass-reinforced surface was smoothly sanded before a final coating of MarineLine® was applied. The entire tanks were then heat cured to ensure the coating work was completed and ready for service.

Today, the first of these advanced tankers, the M/T Puli is already in service. The ship was recently purchased from KS Shipping by UNI TANKERS of Denmark and renamed the “Fionia Swan.” The second ship, the M/T Puli I has also been completed with the MarineLine® coating and lining system. Ship delivery will be this fall. This ship has also been sold, to the Netherlands-based company Lauranne Shipping. The M/T Puli II is in progress now at Cicek, and the final two ships in the series will be completed after that.

As IMO-II approved chemical tankers, these vessels have ‘Clean Sea’ notation and Bureau Veritas Ice Class 1A certification so they can operate in the Baltic year round. They also are designed to carry the maximum number of different cargos, complying with the industry’s highest standards. This enhanced lining system provides excellent resistance to a wide range of ultra-aggressive agents, while the MarineLine®-impregnated fiberglass lining delivers ongoing protection against mechanical damage, a solution that other chemical tanker operators will want to emulate in the future.
