The method of supporting and lowering a subsea package load on an umbilical from the deck of an offshore service vessel to a subsea work location including providing a reel to store the umbilical on the deck which is not capable of sustaining the maximum load, providing a supporting tractor with dual chains which have multiple dogs mounted on skewed surfaces which amplify a spring load support against the umbilical for frictional support of the umbilical and therefore the subsea package.
