What is MarineLINE®

Key Coatings Benefits

  • MarineLINE® 784 from Advanced Polymer Coatings, is the premier cargo tank coating system available for chemical and product carriers, and the only high-performance lining that withstands all IMO approved chemical cargoes.
  • MarineLINE® is generally recognized as safe (GRAS) for food grade cargoes. MarineLINE® 784 coating complies with the FDA and all applicable food additive regulations.
  • More chemical resistance than stainless steel, phenolic epoxies, and zinc silicate coatings.
  • Superior resistance to acids, alkalis, and solvents; maximum versatility to carry CPPs, PFADs, Bio-Fuels, and Methanol.
  • Virtually non-permeable for assurance of product purity.
  • Superior bond strength and adhesion.
  • Very low VOC - 99 grams/L (0.80 lbs./gal.).
  • Excellent flex stressing.
  • Resistance to wear, abrasion and impact.
  • Thermal shock resistance -40°C to +150°C (-40°F to +302°F).

Key Performance Benefits

  • Shipowners generate strong return on investment (ROI).
  • Faster, easier, more efficient cleaning due to non-absorption, low surface energy, and smooth surface.
  • Inspection of tank coating application and curing by MarineLine professionals.
  • Easy tank cleaning with fewer slops, and fast drying.
  • Minor tank touch-up repairs are done easily.
  • ABS ISO 9001:2008 Certification.
  • MarineLINE® 784 is ABS Type Approved.

Cargo Tank Coating ROI

marineline-roi-chart

This 5-year comparison of MarineLINE® versus Phenol Epoxy coatings shows the tremendous difference in Additional Return On Investment. Chart calculations are based on data accumulated from a number of tanker shipowners.

25,000 DWT Tanker, nine voyages per year @ $20,000 USD per day

  1. 3 less cleaning days per voyage than Phenol Epoxy (27 more sailing days)
  2. 50% less cleaning chemicals used
  3. 50% fewer slops
  4. MarineLINE® cargo tank coating is fully cured when leaving the shipyard, so additional income is earned as MarineLINE® can immediately carry all cargoes on the MarineLINE® resistance list.

A History of Performance

The MarineLINE® cargo tank coating has been applied to more than 700 maritime chemical and product tankers, covering over 10 million square meters of surface.

  • The majority of ships coated are over 8 years old with some over 15 years old.
  • MarineLINE® has been applied successfully in major shipyards around the world.
  • These tankers have carried thousands of different chemicals, including Acids, Caustics, Solvents, Inorganic Chemicals, and Edible Oils, with some tankers changing their chemical cargoes up to 85 voyages a year.
  • APC’s MarineLINE® coating withstands the stresses of twisting and bending in rough seas while resisting temperature extremes of the cold Baltic winters to the hot Middle East summers.

The MarineLINE 784® Solution Utilizes Polymer Technology

MarineLINE® 784 is formulated with a patented polymer, designed and engineered with high functional groups per molecule. When heat cured, MarineLINE® 784 coating forms three-dimensional, screen-like structures with up to 784 cross-links. This far surpasses Epoxies that only deliver two functional groups with only four cross-links.

This more densely cross-linked molecular structure delivers:

  • Higher Chemical Resistance
  • Higher Temperature Resistance
  • Higher Reactivity at Lower Temperature
  • Higher Resistance to Absorption
  • Greater Toughness
  • Faster Tank Cleaning

The Greater the Distance Between the Cross-links, the Greater the Permeation Causing Chemical Attack and Absorption

Chemical Concentration

MarineLine-Chemical-Concentration-chart

Over the past 10 years of voyages of MarineLINE® coated vessels, the tanks have never had a contamination claim. As this chart illustrates, the cross-linked structure of MarineLINE® coating does not absorb the cargo, thus ensuring product purity, from port to port.

Operational Efficiencies of MarineLINE®

Long Service Life Potential

Taking care of your MarineLINE® cargo tank coating with proper cleaning and regular maintenance can provide years of profitable service. Well maintained MarineLINE® tanks have been in service 10+ years, and are still performing well. The following UNRETOUCHED photographs of tankers at various inspection intervals provide some insight into the performance of MarineLINE®. For some tanks, minor coating repairs have been made using the MarineMEND Repair system (see below).

marineline-longevity

Easy Cleaning

MarineLINE® 784 has an ultra-smooth, glossy, low energy surface that reduces venting time, uses less cleaning chemicals and less fuel/energy for cleaning equipment, and leads to faster turnaround.

A wide range of approved cleaning detergents and chemicals can be used to clean and prepare the coating for next cargoes allowing the shipowner/operator to maintain the coating with minimal effort.

A number of shipowners have provided examples of their MarineLINE® cleaning practices which APC readily shares with others upon request. A properly cleaned and maintained MarineLINE® cargo tank coating should provide excellent service for many years.

Simple Coating Repair for Small Areas

The MarineMEND Repair System Kit is designed for minor repairs of MarineLINE® coated cargo tanks. The repair procedure can be used when the coating has minor mechanical damage.
