Independent On/Off Hire condition surveys performed onboard commercial vessels focused on documenting vessel condition, bunker quantities, visible damages and operational observations during delivery and redelivery attendance under charter party requirements.
Operational & Contractual Verification
On/Off Hire surveys are commonly performed to document the operational condition of commercial vessels at the time of delivery or redelivery between Owners and Charterers. Particular attention is generally given to visible damages, cargo spaces condition, bunker quantities onboard and operational observations relevant to charter party responsibilities and potential commercial disputes.
Typical Survey Scope
Attendance may include inspection of cargo holds, hatch covers, deck areas, accommodation condition, navigation bridge, engine room spaces, visible structural condition and operational equipment depending on vessel type and operational accessibility during attendance.
ROB Bunker Quantities
Remaining onboard bunker quantities are commonly verified during delivery and redelivery attendance through sounding procedures, temperature verification, density checks and bunker quantity calculations intended to document fuel quantities at the time of attendance.
Operational Observations & Damages
Typical operational observations may include visible structural damages, cargo hold condition deficiencies, hatch cover observations, maintenance concerns, operational deficiencies and onboard conditions potentially relevant to charter party responsibilities and commercial claims.
Survey Reporting
Survey findings are documented through practical operational reporting including vessel condition observations, bunker quantity calculations, visible damages and operational remarks relevant to delivery and redelivery attendance. Depending on operational requirements, bunker calculations and bunker statements may be issued onboard at the time of attendance or incorporated into final reporting issued after vessel departure.
