Eco-Friendly Marine Coatings & Lubricants: A Sustainable Shift

If you own or operate a boat, ship, or fishing vessel in India, you're likely familiar with the impact that maintenance has on the marine environment. From hull coatings to hydraulic oils, traditional marine products are often petroleum-based and harmful to aquatic life. Thankfully, things are changing. With the shift towards eco-friendly marine coatings and lubricants, the Indian maritime industry is starting to adopt greener practices—without compromising on performance.

In this blog, we’ll break down everything you need to know about eco-friendly coatings and lubricants, their benefits, and how they play a critical role in sustainable marine operations. Whether you're a shipbuilder in Kochi, a fishing boat operator in Gujarat, or a marine mechanic in Chennai—this guide is for you.

What Are Eco-Friendly Marine Coatings and Lubricants?

Eco-friendly marine coatings and lubricants are specially formulated products that have minimal impact on the environment. These products are:

• Biodegradable – they break down naturally without harming marine life
  
  

• Non-toxic – free from heavy metals and harmful chemicals like copper or zinc
  
  

• Low-VOC – emit fewer volatile organic compounds, which are bad for air quality

Unlike conventional materials, these green alternatives help reduce pollution while maintaining the performance of marine equipment and parts in harsh sea conditions.

Why Sustainability Matters in the Marine Industry

India has over 7,500 km of coastline and supports nearly 4 million people through fishing and coastal activities. However, according to a report by the Central Marine Fisheries Research Institute (CMFRI), oil spills, toxic coatings, and waste discharge from boats are contributing to water contamination and decline in fish population.

Moreover, with global regulations tightening (like IMO 2030) and Indian ports now pushing for green shipping practices, the shift towards sustainable marine maintenance is no longer optional—it’s necessary.

Types of Eco-Friendly Marine Coatings

Let’s talk about the types of coatings you can consider for your vessel:

1. Water-Based Hull Coatings

• VOC-free and safer for applicators
  
  

• Offers decent antifouling performance for boats operating in low-fouling areas
  
  

• Ideal for wooden and fibreglass boats

2. Silicone-Based Foul Release Coatings

• Smooth finish reduces drag and prevents marine growth
  
  

• Increases fuel efficiency by up to 6–8%
  
  

• Best suited for commercial vessels and fishing trawlers in tropical waters

3. Copper-Free Antifouling Paints

• Unlike traditional antifouling paints, these do not leach heavy metals
  
  

• Safer for coral zones and inland waters like the Sundarbans or Goa backwaters
  
  

• Long-lasting with 1.5 to 2-year protection
  
  

🧪 A study by the Indian Institute of Technology Madras (2022) shows that copper-free coatings reduce underwater metal leaching by over 85%.

Types of Eco-Friendly Marine Lubricants

Marine vessels require lubrication for moving parts like propeller shafts, steering systems, deck winches, and cranes. Here's what to use instead of mineral oils:

1. Biodegradable Hydraulic Oils

• Used in steering systems and winches
  
  

• Breaks down rapidly in water, reducing the risk of marine pollution
  
  

• Ideal for trawlers and harbour tugs operating in sensitive zones

2. Eco Grease for Bearings and Deck Gear

• Resistant to water washout
  
  

• Suitable for gearboxes, cranes, and marine winches
  
  

• Long shelf life and fewer applications required

3. Environmentally Acceptable Lubricants (EALs)

• Approved under US EPA’s VGP (Vessel General Permit) and accepted globally
  
  

• Used in propeller shafts, thrusters, and rudder systems
  
  

• Now available from top brands like TotalEnergies, Gulf, and local Indian manufacturers

Benefits of Going Green with Marine Lubricants and Coatings

Here’s why switching to eco-friendly options is a smart move:

• Reduces Water Pollution: Prevents chemical leaks and metal runoff into oceans
  
  

• Improves Equipment Life: Greener products are often less corrosive and extend part lifespan
  
  

• Regulatory Compliance: Helps avoid fines from DG Shipping and other authorities
  
  

• Boosts Fuel Efficiency: Smoother hull = lower drag = better fuel savings
  
  

• Enhances Brand Value: Great for exporters and operators focusing on ESG goals
  
  

📈 Indian shipowners who switched to eco-lubricants reported a 10–12% reduction in part wear and tear (Marine Engineers Association Survey, 2023).

Government Guidelines and Certifications in India

The Directorate General of Shipping (DG Shipping) and Indian Coast Guard have begun enforcing stricter rules around marine discharge and pollution. When choosing green coatings or lubricants, look for:

• BIS certifications for quality standards
  
  

• ISO 14001 compliance for environmental safety
  
  

• IMO-compliant formulations under MARPOL Annex V
