The offshore diver may do a wide range of tasks in support of offshore drilling or production. Much of the offshore seabed diving work is inspection, maintenance and repair of the (BOPs) and their permanent guide bases. The primary functions of a blow-out preventer system are to confine well fluid to the wellbor. [pdf]
DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanism followed the bit down into the hole. Applications were later found for the DTH method underground, where the direction of drilling is generally upwards instead of downwards. [pdf]

A is first thought to have been used for rock drilling in 1844. Many quarries used hand held tools that required the driller to suspend himself from a rope over the quarry face in order to place the drill hole in the required position. This system used small diameter holes and was not only terribly inefficient, but very dangerous due to flying rock as a result of the inaccuracy of the drilled borehole. [pdf]
The system is thought to have been invented independently by Stenuick Frères in Belgium and Ingersoll Rand in the USA in the mid-1950s. DTH is short for “down-the-hole”.OverviewA down-the-hole drill, usually called DTH by most professionals, is basically a screwed on the bottom of a .
