Load line survey

In order detecting whether the vessel is over-loaded and it’s freeboard,

it is basically an effort to make the hull watertight below the freeboard and weather tight above it.

 

It is a administration requirement for ships to get Load line certificate which is subjected to annual survey.

• 150 GRT and above
• New ship of length 24m and above

It is calculated by classification to ensure ships

• • 1. Floating stability
    2. Reserve buoyancy ( volume of above waterplane to be watertight increase buoyancy)
    3. Freeboard
    4. Amount of cargo loaded
    5. Watertight integrity

Survey

Ship is subjected to 

1. 1. 1. 1. 1. Initial survey
            2. Periodical survey ( not exceed 5 years)
            3. Annual survey 

Certificate

1. 1. International load line certificate
   2. Stability certificate,
   3. Inclining test certificate
