optic cables, which terminates in a junction box on the winch. This bundle needs protecting from sea spray and harsh offshore environments to maximise its service life and provide trouble-free operation,” says Cronin. In the subsea environment it is essential that power is maintained for data to the ROV, because when the ROV is not working, it means the entire rig is down and not drilling. Providing ongoing protection for the slip ring from the environment is therefore vital. Enquiries: Mike Cronin.Tel. 011 826 7117

Elquip Solutions has introduced a high-end, com- prehensive range of flexible conduit systems and components from UK manufacturer Flexicon to the local market. These conduit systems provide superior cabling protection, particularly in high-demand, hazard- ous environments such as in the rail or mining industries. Further demonstrating its versatility, Flexicon’s liquid-tight conduit system has been used to protect the power supply to subsea remotely-operated vehicles (ROVs) in the oil and gas industry in Brazil, China and Australia.

The 63 mm LTP conduit and special engineered fittings are used to protect the slipring con- nections inside the winch. This provides 3,3 kV feeds to the power transmission system, which connects the subsea ROV to the surface, according to Mike Cronin, managing director of Elquip Solutions. “In addition to the power ca- bles, fibre optic elements are included in the single cable con- nection system called an ‘umbili- cal’.The tail from the slip ring is a loose bundle of copper and fibre

Specially plated – more stability

The increasing modularisation of industrial pro- duction facilities and the rise in mobile equipment employed is resulting in growing demand for connectors capable of High Mating Cycles (HMC). The launch of the new Han-Modular Hinged frame HMC now enables the integration of Han-Modular components into HMC connectors.

The Han-Modular system can now handle HMC as well – the key component being the new Han- Modular Hinged frame HMC which is designed to handle more than 10 000 mating cycles.The new Han-Modular Hinged frame HMC sets itself apart from conventional hinged frames in particular in terms of the PE contact. The contact is specially

plated and boasts increased fixation stability in the frame of the Hinged frame HMC. Since the Han HMC hous- ing is executed with IP65 protection, the new HMC hinged frame also opens up new application fields for Han-Modular. Not only can Han-Modular connectors be plugged and unplugged many thousand times, the modules in HMC housings are also especially well pro- tected against mechanical loads, contact and dust accumulation as well as against water spray.
