On-Hire/Off-Hire Surveys: Prot...

On-hire and off-hire surveys are critical inspection processes conducted at the commencement and conclusion of vessel charter periods. These surveys document vessel condition, equipment functionality, and cargo space status to protect the commercial interests of both owners and charterers. This article explains the purpose, process, and importance of these specialized marine surveys.

Purpose and Importance On-hire and off-hire surveys serve multiple important functions:

1. Condition Documentation: Establishing the vessel's condition at delivery and redelivery
2. Bunker Verification: Documenting fuel quantities for financial settlement
3. Equipment Functionality: Verifying operational status of vessel equipment and systems
4. Cargo Space Condition: Assessing cleanliness and suitability of cargo spaces
5. Damage Identification: Documenting pre-existing or new damage
6. Dispute Prevention: Creating objective records to prevent disagreements
7. Charter Party Compliance: Ensuring the vessel meets contractual requirements

On-Hire Survey Process The on-hire survey is conducted when the vessel is delivered to the charterer and typically includes:

1. Documentation Review:
   • Vessel certificates and class status
   • Maintenance records and previous survey reports
   • Equipment manuals and inventories
   • Charter party requirements
2. Physical Inspection:
   • Hull condition above and below waterline where possible
   • Cargo spaces condition and cleanliness
   • Hatch covers and closing appliances
   • Cargo handling equipment and gear
   • Navigation and communication equipment
   • Engine room and machinery spaces
   • Safety equipment and lifesaving appliances
   • Accommodation spaces as specified in charter
3. Operational Testing:
   • Cargo handling equipment under load where practical
   • Navigation equipment functionality
   • Communication systems
   • Vessel propulsion and maneuvering systems
   • Auxiliary systems critical to vessel operation
4. Bunker Survey:
   • Measurement of all fuel, diesel, and lubricating oils
   • Verification of tank calibration tables
   • Calculation of quantities for commercial handover
5. Inventory Verification:
   • Spare parts as specified in charter
   • Equipment and stores to be provided with vessel
   • Consumables included in charter terms
6. Photographic Documentation:
   • Comprehensive photographic record of vessel condition
   • Special attention to any pre-existing damage
   • Documentation of cargo space condition

Off-Hire Survey Process The off-hire survey is conducted when the vessel is redelivered to the owner and follows a similar process with emphasis on:

1. Comparison to On-Hire Condition:
   • Identification of any new damage or deterioration
   • Assessment of overall condition relative to delivery state
   • Verification that charterer's maintenance obligations were met
2. Bunker Quantity Determination:
   • Final measurement of all fuel grades and lubricants
   • Calculation of consumption and quantities for financial settlement
3. Equipment Functionality Verification:
   • Confirmation that all equipment is in working order
   • Documentation of any deficiencies for potential claims
4. Cargo Space Inspection:
   • Cleanliness and condition of holds or tanks
   • Presence of cargo residues or contamination
   • Damage to cargo space structures or fittings
5. Final Documentation:
   • Comprehensive report comparing on-hire and off-hire condition
   • Detailed inventory of outstanding deficiencies
   • Recommendations for necessary repairs or cleaning

Key Focus Areas by Vessel Type

1. Dry Bulk Carriers:
   • Hold cleanliness and suitability for next cargo
   • Hatch cover watertight integrity
   • Cargo handling equipment functionality
   • Hold structure and coating condition
2. Tankers:
   • Tank cleanliness and previous cargo residues
   • Coating condition in coated tanks
   • Pumping and pipeline system functionality
   • Inert gas and tank cleaning systems
3. Container Vessels:
   • Cell guide condition
   • Lashing equipment inventory and condition
   • Reefer plug functionality
   • Hatch cover and lashing bridge condition
4. General Cargo Vessels:
   • Cargo gear certification and functionality
   • Tweendeck condition and securing arrangements
   • Hold cleanliness and suitability
   • Access arrangements and safety provisions

Special Considerations

1. Time vs. Voyage Charter: The scope and detail of surveys often differ between time charters (where the charterer operates the vessel) and voyage charters (where the owner retains operational control).
2. Bunker Sampling: Modern practice often includes taking representative samples of bunkers during both on-hire and off-hire surveys to address potential quality disputes.
3. Speed and Consumption: For time charters, vessel performance regarding speed and fuel consumption may be verified through sea trials or analysis of voyage data.
4. Joint Surveys: When possible, surveys should be conducted jointly with representatives of both owner and charterer to minimize disputes.
5. Charter Party Review: Surveyors should be familiar with specific charter party terms that may affect survey scope and acceptance criteria.

Survey Reports and Documentation Professional on-hire/off-hire survey reports typically include:

1. Factual Documentation: Objective description of vessel condition
2. Photographic Evidence: Comprehensive visual record
3. Quantitative Measurements: Bunker quantities, equipment readings
4. Comparative Analysis: For off-hire surveys, comparison to on-hire condition
5. List of Exceptions: Deficiencies or damage noted
6. Recommendations: Suggested actions for noted issues

On-hire and off-hire surveys represent critical risk management tools in vessel chartering. When conducted thoroughly by qualified surveyors, these inspections protect both owners and charterers by documenting vessel condition objectively, preventing disputes, and providing the factual basis for any necessary financial adjustments at the conclusion of the charter period.
