 Tank Cleanliness Survey

By Bashan & Gilead Marine Services Pte Ltd (BGMS)

A Tank Cleanliness Survey is an essential inspection conducted to verify that cargo or fuel tanks onboard a vessel are clean, free of contaminants, and safe for their intended use. At BGMS, we conduct independent tank cleanliness surveys to support operational safety, cargo integrity, and regulatory compliance.

Clean tanks are critical for maintaining safety, product quality, and operational efficiency. The key objectives of a tank cleanliness survey are:

Residual substances—such as sludge, previous cargo residues, or volatile vapors—can pose significant fire and explosion risks. Our survey helps identify such hazards and ensures the tank is safe for:

• Loading new cargo (especially different or sensitive grades)
   
• Entering confined spaces (for crew or contractors)
   
• Hot work or maintenance operations
   

Tank contamination can compromise the integrity of new cargo—especially fuels, chemicals, or food-grade products. Our survey:

• Detects residues, rust, scale, or water accumulation
   
• Prevents cross-contamination between cargoes
   
• Ensures tanks meet required cleanliness standards (e.g., white product spec)
   

Many flag states, port authorities, and charterers require verified tank cleanliness, especially when:

• Switching between incompatible cargoes
   
• Preparing for inspection or cargo survey
   
• Complying with MARPOL, IMO, and local port regulations
   

BGMS ensures your vessel complies with applicable regulations and avoids potential penalties or delays.

Our surveys can identify issues with the tank cleaning process, such as:

• Ineffective cleaning methods
   
• Inadequate frequency or flushing routines
   
• Improper use of cleaning chemicals or procedures
   

Correcting these inefficiencies supports smoother cargo operations and minimizes downtime.

A clean tank is less prone to:

• Corrosion and long-term damage
   
• Cargo rejections or contamination claims
   
• Additional port delays and demurrage charges
   

Investing in tank cleanliness inspections helps protect your asset and cargo value while controlling operational costs.
