Review of Drawing of PJT Cargo

KOMSA has many experiences of MWS & Towage surveys on big projective cargoes, i.e, RTGC, RMQC, Evaporator, CSU, Floating Crane & Etc. reviewing engineer drawing with our engineering program.

Through the engineering meeting, we advise the concerned the safety sea-fastening and rolling, pitching, heaving degree and sufficient lashing for sea-transportation.
