The Science Behind it All

Performance Starts at the Molecular Level

More Reactive Sites. More Potential for Crosslinking.

MarineLINE® performance begins with APC’s proprietary high-functionality polymer technology. From initial crosslinking to the final cured surface, its molecular structure is engineered to create a denser barrier, reduce cargo absorption, and make tanks easier to clean.

Conventional Novolac Epoxy

Fewer reactive sites

Lower polymer functionality provides fewer reactive sites available for crosslinking.

MarineLINE Technology

Significantly more functionality

APC's proprietary polymer contains significantly more reactive functionality, creating greater potential for crosslinking as the coating cures.

02Why It Matters

Turnaround Time Is Earning Time.

$370K–$470K gain in potential annual on-hire value per MR vessel

$15K in annual cleaning chemical savings

Operational Outcomes

Faster Cargo Changes — Achieve demanding water-white and wall-wash cleanliness standards with tank turnaround up to 2.5 days faster per cleaning operation.
More Vessel Availability — Gain 10.5–13.5 potential additional on-hire days per year, representing $370K–$470K in potential annual on-hire value per MR vessel under certain trade patterns.
Lower Cleaning Costs — Reduce reliance on cleaning chemicals, delivering up to $15K in annual cleaning chemical savings while supporting faster tank preparation.

Case Study

Lab-Tested, Shell Approved: MarineLINE® Moves to List of 'Approved' Methods for MEG Carriage via Shell Cargo Handling Sheet

Monoethylene glycol (MEG) carriage was long restricted to stainless steel tanks over contamination concerns. Following a study with Shell's chemists, and APC's own benzene-to-MEG carryover testing, MarineLINE® has been added as an approved method for carrying MEG, giving operators greater vessel flexibility without compromising purity.
