After a thorough analysis of the customer's requirements, PPG finally went with a 36-month 'hybrid' system comprising the SIGMAGLIDE 1290 fouling release for the vertical sides and the SIGMA NEXEON 710 coating for the flat bottom. The dry docking had a very short lead time of under 14 days and was awarded against a number of very competitive offerings.
PPG Protective & Marine Coatings (PPG) was invited by GASLOG in September, 2014 to specify its best fouling release coating system for six LNG vessels previously coated with a competitor’s fouling release coating. Overcoating a competitor fouling release coating is always a challenge due to the different, related technologies.
PPG Protective & Marine Coatings (PPG) has a long- standing relationship with Carisbrooke Shipping having delivered coatings to the company’s new-building vessels constructed in a number of European and Far Eastern countries. Building on this close relationship, all vessels in this series at Jiangsu Yangzijiang were allocated to PPG for the provision of coating systems on their internal and external surfaces. The system applied at the new-building stage in China was SIGMACOVER 380.
Wagenborg Shipping was looking for a coating system for their L-series vessels. The main requirement was that the system should be easier to apply for onboard staff. PPG proposed the SIGMADUR ONE single-pack finish coat to reduce the coating process complexity and make it easy for the crew to apply the coating and simplify stock control. Since the application of the SIGMADUR ONE system, Wagenborg has seen much improved results in maintaining their vessels.
For the Marietje Nora, Danser van Gent were looking for a durable and robust coating system. PPG proposed the PSX 700 system to meet the customer’s criteria. Since its introduction in 2003, the PSX 700 system has been widely acclaimed by customers for its long- term durability and outstanding performance in harsh conditions. The PSX 700 topcoat delivers unrivaled performance while complying with the most exacting VOC regulations.
The B-Class vessels Balticborg and Bothniaborg operate between The Netherlands, Germany, Sweden and the UK to a tight schedule with very limited maintenance time. They also face severe ice conditions in winter, so the hulls need excellent, long-lasting protection to ensure reliable, economical performance levels. SIGMASHIELD 1200 was therefore specified to minimize damage, reduce subsequent repair costs and improve operational efficiency.
We proposed the SIGMADUR ONE finish coat to reduce the coating process complexity and make it easy for the Stena Transporter crew to apply the coating and simplify stock control.
The SIGMADUR ONE coating is an ideal, user-friendly, heavy-duty finish to support crew members during onboard maintenance. Instead of a typical two-pack finish, it comes in one pack, so no mixing is required, which saves time and reduces mistakes during application.
In 2008 PPG Protective & Marine Coatings (PPG) started to work together with ESVAGT in order to provide a suitable solution for their fleet. Initially this involved test applications of our newly developed SIGMA ECOFLEET 690 product and this in-depth development finally resulted in the first full application to one vessel in early 2011. Since then, the in-service operational results have been closely monitored to ensure that all the performance targets are being successfully met.
PPG Protective & Marine Coatings (PPG), created the SIGMA ECOFLEET 690 product to deliver excellent self-polishing antifouling for extreme and aggressive fouling conditions.
The SIGMA ECOFLEET 690 antifouling has been formulated using PPG’s unique patented binder technology ensuring consistent performance levels and fouling control for in-service periods of up to 60 months.
As an optimal coating for the protection of a vessel’s underwater hull from fouling and discoloration, the SIGMA NEXEON 750 antifouling offers exceptional performance for static- and low-activity vessels at new-build.
The high-performance silyl acrylate SIGMA SAILADVANCE DX antifouling was chosen in May 2012 for application at the COSCO Dalian shipyard in China.
In addition to keeping the ship’s hull free from fouling, the product’s silyl-acrylate polymer technology also contributes positively to the hydrodynamics of the ship’s hull by reducing hull frictional drag and, crucially, the amount of fuel consumed.
SCF Unicom chose SIGMA SAILADVANCE DX in order to benefit from the excellent linear polishing and self-smoothing properties provided by the advanced silyl acrylate binder. The product is a premium self-polishing, self-smoothing silyl acrylate antifouling. In addition to keeping the hull free from fouling, its silyl-acrylate polymer technology also contributes positively to the hydrodynamics of the ship’s hull by reducing hull frictional drag and, crucially, the amount of fuel consumed.
PPG has developed a unique online system: SIGMACARE PLUS, which has been specifically designed to simplify onboard coatings management for vessels and large fleets. This revolutionary tool now makes it easier to carry out onboard maintenance for owners, vessel management and crew members. In essence, SIGMACARE PLUS eliminates the complication often associated with onboard maintenance, maximizes efficiency and reduces waste in management time, onboard manpower and product usage.
Acting in accordance with its stringent corporate focus to apply the latest innovations in marine protective coatings and, after extensive research and evaluation, the company chose the SIGMAGLIDE 990 biocide-free fouling release from PPG Protective & Marine Coatings. PPG is the only company with long and extensive experience in both premium silyl acrylate antifoulings and silicone-based fouling release coatings. This enables us to offer a bespoke solution for each customer.
Fuel costs are a growing burden for the shipping industry. At PPG, we anticipated this trend and engineered the most advanced pure silicone fouling release system: the SIGMAGLIDE 990 coating. This innovative system is formulated to help owners and operators save fuel costs, while at the same time improve their environmental footprint by reducing green house gas emissions and help them to achieve a biocide-free operation.
PPG’s unrivaled knowledge in coating technology provides the ideal basis to increase a vessel’s profitability and productivity: the SIGMAGLIDE biocide-free, silicone fouling release system, specially formulated to provide optimal hull smoothness. A key advantage over other technologies for ships in service is that the silicone fouling release system provides a smooth surface from the outset – so fuel savings are realized immediately.
At PPG, we foresaw the issue of rising fuel costs and developed the most advanced pure silicone fouling release system on the market: the SIGMAGLIDE 990 coating. This innovative system helps owners and operators save fuel costs, while at the same time improves their environmental footprint by reducing GHG emissions and helps them to achieve a biocide-free operation.
Success or failure of coatings in service can influence the profitability rate at which a ship operates. Ship owners have to carefully consider the coating choices needed for each specific vessel area, taking into account factors such as service conditions as well as substrate type. SIGMAPRIME is a high-quality epoxy primer designed to fit shipyard building practices and offer excellent long-term protection.
PPG Protective & Marine Coatings (PPG) offers two abrasion-resistant, ice coatings (SIGMASHIELD 460 and SIGMASHIELD 1200). These were selected based on the anticipated ice conditions during service life. The SIGMASHIELD 1200 coating is based on a very hard filler composition, providing excellent anti-abrasion properties, and on a highly cross-linked phenolic epoxy technology, further extending the service life of the coating by tremendously increasing the creep resistance.
PPG Protective & Marine Coatings convinced Boskalis, after 2 years of extensive testing both in-house and externally, that SIGMASHIELD products would provide the most durable coating solution for cargo holds. PPG applied a system comprising the SIGMASHIELD 1090 product as an under layer with the SIGMASHIELD 1200 coating as a finish layer on top to the Causeway.
Over the past 30 years, the PHENGUARD system has consistently given ship owners the ability to carry an exceptionally wide range of cargoes, including highly aggressive loads such as methanol, EDC and fatty acids.
