US based Advanced Polymer Coatings reports record growth driven by rapidly changing market


USA based Advanced Polymer Coatings (APC), the owner of the MarineLINE cargo tank coating brand, is announcing its most successful year of trading with maritime sales growing by 40 per cent in 2021.

The Ohio headquartered family firm, led by President David Keehan, now says it accounts for more than 12 per cent of the global cargo tank coating market and is specified on more than 700 ships, with 56 ships coated equating to over 750,000 square meters of MarineLINE applied in 2021.

Mr Keehan said growth is being driven by a rapidly changing shipping landscape. He said decarbonisation is exerting huge pressure on operators, notably charterers, who are now searching out products like MarineLINE to help achieve emission targets. He noted MarineLINE’s ability to cut average tank cleaning times by two days per voyage, compared to standard coatings, led to a three per cent annual fuel reduction cutting carbon emissions by 4500 MT per annum per tanker as well as significant fuel savings.


Mr Keehan said exports are underpinning APC’s growth with key markets including China, the Gulf, Croatia, and Turkey.


“We are seeing more changes in the tank coating market than any point in the last ten years,” he said. “MarineLINE has always been positioned as a premium product, as we specialise solely on tank coatings. We are not a generalist paint company attempting to coat the entire ship. That model is becoming less appealing as operators are now much more aware that when tank coatings go wrong it can cost millions of dollars per ship to repair plus disruption and lack of availability. Another trend we are observing is that charterers are influencing the selection of tank coatings, and they are hungry for cost and emissions savings. The charterers want to secure long-term deals with ship owners. They want to know the coating can perform and cope with a wide variety of chemicals over a sustained period without risk of cross contamination. When you consider that a ship can be expected to carry 85 different chemicals a year across 16 cargo tanks this is one of the biggest issues and costs an operator can face. In addition, decarbonisation is becoming more and more of an issue and is a growing advantage for MarineLINE. MarineLINE’s ability to reduce tank cleaning times slashes fuel use and emissions (see notes to editors) and that combined by our ability to carry a versatile range of products is giving us an edge and we back that up with a five-year warranty.”


Mr Keehan said APC’s growth is further being helped by new senior appointments to the team. New faces joining in 2021 include Captain Tore Svensen, a chemical tanker specialist and former head of fleet at UACC in the Gulf, and Kenneth Rogers a former head of Aurora Tankers in Singapore who has also held senior positions with Carnival, SEACOR and Seabulk. Mr Keehan said both Tore and Kenneth are bringing deep market knowledge and contacts.


“Building on the success of 2021 and our growing maritime customer base this year will see APC further embrace digitisation,” he said. “We are developing an in-house digital portal to give operators more time information and data about ship performance. We aim to launch that this year to support our drive to grow particularly in Asia and Europe.”


Elsewhere Mr. Keehan said he is particularly proud that APC is committed to philanthropy with donations to a range of charities exceeding $1million. APC’s nominated charities include St Jude Children’s Research Hospital in Memphis, the Toys for Tots Foundation, The St Augustine Hunger Centre, Prayers for Maria Children’s Glioma Cancer Research Foundation in Ohio, and St Edward High School in Ohio where Mr. Keehan formerly taught entrepreneurship.

Zinc Coated Vessel
• 56 hours of hot water washing produces 106.4 MT of CO2

• 12 hours of hot water washing produces 22.8 MT of CO2


Example: A vessel “costs” $18,000 per day
• A vessel has 16 cargo tanks.
• 4 cargo tanks can be cleaned simultaneously.
• Each cargo tank requires 200L of cleaning chemicals.
• The typical cost of a regular cleaning chemical is $3 per Litre


Zinc coated vessel MarineLINE
Total Cleaning Time 64 hours 16 hours
Hot Water Cleaning Time 56 hours 12 hours
Cleaning Chemical Consumption 3200L 0L


  • The financial advantages of a MarineLINE versus zinc silicate in this example can be quantified as follows:
