🇧🇷 Brazil’s New Biofouling Rules (2026): What Every Ship Owner & Master Must Know — Simply Explained

 🇧🇷 Brazil’s New Biofouling Rules (2026):

What Every Ship Owner & Master Must Know — Simply Explained

By ShipOpsInsights with Dattaram

“In shipping, small oversights can create big delays. Preparation is the cheapest compliance.”

From 1 February 2026, Brazil will strictly enforce new hull cleanliness (biofouling) regulations for vessels calling at Brazilian ports. These rules are aligned with the IMO 2023 Biofouling Guidelines and will directly impact voyage planning, inspections, and port readiness.

This is not a paper regulation.
This is a physical hull condition requirement.

Let’s break it down clearly, practically, and without jargon—the ShipOpsInsights way ⚓

 

🌊 1. What Is Biofouling & Why Brazil Is Serious About It

Biofouling simply means marine growth on a ship’s hull—slime, algae, barnacles, shells. Over time, this growth increases fuel consumption, reduces speed, and most importantly for Brazil, harms the local marine ecosystem.

Brazil has vast and sensitive coastal waters. To protect them, authorities now require ships to arrive with near-clean hulls, not visibly fouled ones. This is no longer optional good practice—it is a port entry condition.

Many vessels operate efficiently for years without visible concern, but one neglected hull inspection can now lead to delays, cleaning orders, or denied smooth transit.

This regulation shifts responsibility upstream—from port arrival to advance planning.

🚢 2. Which Vessels Must Comply (Yes, This Includes Most Ships)

The rule applies to:

• All vessels calling Brazilian ports
• Length more than 24 meters (LOA)

This means bulk carriers, tankers, container ships, gas carriers, offshore vessels—almost the entire trading fleet.

There are no exemptions based on flag, age, or trade type. If your vessel is over 24m LOA and calling Brazil, compliance is mandatory from 01 February 2026.

Owners and Masters should treat this the same way we treat Load Line, MARPOL, or PSC requirements—non-negotiable.

📋 3. Mandatory Documents to Be Onboard (Paper Matters Here)

Brazil requires two specific documents, aligned with IMO guidelines:

1️⃣ Biofouling Management Plan (BFMP)

This explains how the vessel manages hull cleanliness, including:

• Inspection routines
• Cleaning methods
• Dry-dock strategy

2️⃣ Biofouling Record Book (BFRB)

This is the evidence log, recording:

• Hull inspections
• Dry dockings
• In-water cleanings

These are not “keep-for-office” documents.
They must be onboard, updated, and consistent.

Inconsistencies between hull condition and records will raise red flags.

🔍 4. Underwater Inspection: The Most Critical Requirement

This is the core operational requirement.

Brazil mandates:

• A valid underwater inspection report
• Report must be within the last 12 months
• Hull condition must be Biofouling Rating 0 or 1

You must also declare the inspection date in YYYY-MM-DD format.

No recent inspection = compliance risk
Inspection showing rating 2+ = cleaning required before arrival

This means underwater inspections can no longer be postponed “until dry dock.”

🟢 5. Hull Rating System: What Is Allowed vs Not Allowed

Brazil uses IMO MEPC.378(80) hull fouling ratings.

✅ Allowed (Entry Permitted)

• Rating 0 – Completely clean hull
• Rating 1 – Only slime / microfouling

❌ Not Allowed

• Rating 2 or higher –
  Light to heavy marine growth (barnacles, weeds, shells)

👉 If your vessel is rated 2+, cleaning must be done BEFORE transit or port call.

There is no “we’ll clean later” flexibility.

🧭 6. What Owners & Masters Should Do Now (Action Plan)

Even though enforcement starts in 2026, smart preparation starts now:

✔ Ensure BFMP & BFRB are prepared and onboard
✔ Schedule regular hull inspections
✔ Plan underwater inspections within 12 months
✔ Monitor hull condition before Brazil voyages
✔ Arrange cleaning well in advance if required

This is not just compliance—it is risk management.

⚓ Final Thought from ShipOpsInsights with Dattaram

“Brazil is not asking for perfection. It is asking for preparation.”

If your hull is clean and your documents are ready, Brazil will be just another smooth port call.

If not—delays, cleaning orders, and commercial impact await.
