In 1969, I had calculated and set a procedure/program for lifting test carried out to the SWL 165- ton heavy derrick of M/V "You Hao", an ocean-going cargo ship of COSCO GUANGZHOU. The testing load was 181.5 T.
Now, when I have retired, I think the calculation about stability and program should be done by the technical department of COSCO and the shipyard, and not by me. I was at a position of surveyor at that time.
Fortunately, no accident was happened. The testing was successful. |
