Lifting and handling products manufactured by the J D Neuhaus company are engineered for performance, reliability and longevity when operating in extreme environments of dirt, dust, high humidity, and even potentially explosive atmospheres. Some of the toughest and more unusual conditions are currently experienced by today’s underwater aquanauts. Divers are very often working alone, in conditions of variable depth water pressures and temperatures, combined with poor visibility while also battling with ocean currents. With all these problems to contend with, any tools they use need to be rugged, reliable, easy to operate and comply with the highest performance standards.
The last few decades has seen unparalleled development in the field of oil and gas exploration, particularly offshore. JDN hoists have played their part in this market, offering hoists with lift capacities from 250kg up to 100 tonnes, with specialised units of 200 tonnes lift capacity having been supplied for BOP handling. The development of subsea hoists means that underwater as well as on-deck lifting operations for a wide range of operational, maintenance and repair functions can be undertaken on jack-up rigs, semi-submersible platforms, drill ships and FPSO vessels. Even undertaking underwater pipeline and wellhead operations down to levels of 70 metres can also be considered.
