A Hatch Sealing/Unsealing Survey is a crucial inspection carried out to verify the integrity of cargo hatch covers during closure and opening operations. At BGMS, we provide independent verification to ensure that hatch sealing and unsealing processes are conducted properly, protecting cargo, ensuring regulatory compliance, and maintaining vessel safety.

Proper sealing of cargo hatches is fundamental to the safe and successful transport of goods—particularly bulk cargoes—over sea. These surveys provide assurance in several critical areas:

Water ingress due to improperly sealed hatches can result in:

• Cargo spoilage or contamination (especially in dry or hygroscopic cargoes)
   
• Legal claims for cargo loss or damage
   
• Rejection of cargo by the receiver
   

Our survey verifies the watertight integrity of hatch covers, ensuring cargo remains secure and protected throughout the voyage.

International maritime regulations and charter party terms often mandate that hatches be properly sealed and recorded before departure. Our survey helps ensure compliance with:

• IMO guidelines and SOLAS regulations
   
• Port State Control inspections
   
• Charterer and cargo owner requirements
   

BGMS provides documented evidence of sealing/unsealing activities, helping vessels avoid penalties or delays.

Poorly secured hatches can present safety hazards to:

• Crew members working on deck
   
• Structural integrity of the vessel in adverse weather
   
• Stability of the cargo due to unexpected ingress of water
   

Our survey identifies any mechanical or structural deficiencies in the hatch system and ensures that sealing/unsealing is completed safely.

We assess the condition and operation of:

• Rubber gaskets and seals
   
• Securing cleats, dogs, and wedges
   
• Drainage channels and compression bars
   

Identifying issues early reduces the risk of cargo delays, unplanned maintenance, or voyage interruptions.

Improper hatch maintenance or unmonitored sealing can lead to:

• Cargo damage and insurance claims
   
• Expensive repairs to corroded or flooded holds
   
• Lost time at port due to failed inspections
   

Routine Hatch Sealing/Unsealing Surveys provide a cost-effective risk management tool to reduce exposure and extend equipment life.

Our surveyors will:

• Witness and document hatch sealing or unsealing procedures
   
• Verify the condition of hatch covers, sealing materials, and securing devices
   
• Ensure proper application and removal of sealing tapes or devices
   
• Take photographs and record detailed observations
   
• Issue a Hatch Sealing/Unsealing Certificate or report with supporting evidence
   

• Experienced marine surveyors with practical knowledge of hatch systems and cargo requirements
   
• Independent, objective verification aligned with client and charterer standards
   
• Detailed documentation for operational and legal use
   
• Commitment to cargo integrity, safety, and compliance
