Sea-Going Tug

A tug built and certified for unrestricted ocean passages, towing barges, rigs, and dead ships between ports or across oceans. It runs large fuel capacity, a deep towing winch with several hundred meters of wire, gob and Norman pins to control the towline lead, and accommodation for long voyages; bollard pull commonly runs from 60 tonnes to well over 200 tonnes on anchor-handling tug supply hulls used for towing. The ocean tow follows an approved towage plan and a marine warranty surveyor’s route assessment. It contrasts with the harbor tug, which works only inside port limits.
