BULK MATERIALS HANDLING
Hoists designed for the oil and gas industry used in FPSO mooring system
The J D Neuhaus company have a long established reputation for the design and manufacture of materials handling products. They also supply purpose designed equipment for specialised applications such as the oil and gas industry where safety and reliability are primary requisites. For this purpose they can supply hoists, with a lift capacity range from 0.25Kg up to 100 tonnes, to API7K certification. These are high durability products rated explosion proof/spark resistant and powered by compressed air or hydraulics with corrosion resistant options also available. Customised lifting and control systems can be accommodated with load test certifications available through DNV, ABS, Lloyds and others. Typical land based or offshore equipment loads include BOP handling, FPSO (Floating Production, Storage and Offloading) vessel mooring/tensioning together with a wide range of general materials handling requirements on jack-up rigs, semi-submersibles, drill ships etc. Specialised hoist applications have also been developed for operation in low temperature ‘cryogenic’ conditions, together with hoists for subsea operation down to levels of 70 metres. The FPSO vessel is used as a temporary storage unit for oil or gas from offshore production platforms before it is subsequently transported by a pipeline or oil tanker to the store depot. An integral piece of equipment on FPSO’s are the hoists used to manoeuvre equipment both on and around the vessel. Subject to heavy loads and harsh environments, the JDN hoists provide an essential ‘strongest link’ in these material handling operations.
Bardex Corporation, headquartered in Goleta, California, was contracted to design and build the mooring system for an FPSO ordered from Elf Petroleum Nigeria, Ltd.
(EPNL), a Nigerian subsidiary of French Oil company Total S.A., and contracted through Hyundai Heavy Industries (HHI). A number of overhead cranes were evaluated before Bardex concluded that JDN’s hydraulic overhead crane was the best option.
Instead of procuring 16 separate chain jack tensioning systems (four per corner of the FPSO and each rated at 18 tonnes), it was determined that one unit per corner could be used and a system of four overhead cranes used to move one chain jack tensioning system for use in all four corners of the FPSO. Additionally, the specially designed mooring system included sixteen fairlead stoppers each weighing in at almost 25 tonnes. A system like this had never been built before, and JDN was the only crane builder in the world capable of supplying it to specification and on time. It comprised a hydraulically powered overhead crane with a hoist lift capacity of 18 tonnes, designed to withstand daily ocean environmental conditions with a high atmospheric moisture content.
Established in 1745, J D Neuhaus products operate safely and reliably in some of the most demanding and difficult environments in the automotive, oil & gas, and mining industries, while offering unmatched quality and superior service.
The stringent regulations, design codes and standards used in the manufacture and production of their products include:

Award-winning Komatsu range promises eco-friendly performance in all conditions
Just over a year after its appointment as a UK distributor for Komatsu Forklifts, Ambassador Lift Trucks is launching the AE50/AM50 series of compact three and four-wheel electric total AC forklift range to the UK market.
Developed to achieve low operating costs, productivity, safety and comfort, the eco- friendly AE50 is Komatsu’s first total AC electric powered lift truck which achieves outstanding energy savings compared with its conventional engine truck models. With its waterproof characteristics and ability to be used outdoors, this unique truck offers users a way to “Go Green” by replacing engine powered models that are used indoors or outdoors with an electric forklift alternative. This could have a dramatic effect for users looking to reduce their carbon footprint and reduce their overall operational costs through reduced maintenance expenditures and lower

costs of re-fuelling. Trevor De’Ath, Sales Director at Ambassador believes the AE50 will be an industry leader. “Nothing will stop the AE50; the performance is exceptional and versatile”, explains Trevor. “With its weatherproof design, the AE50 can be used outside in adverse weather conditions with maximum efficiency. The high-speed charger and side battery access and removal make the exchange safer and smoother making it ideal for continuous operations.” In addition to fuel savings, the total AC system offers a power and controlled drive system, hydraulic and power steering system with no DC motors. The AE50/AM50 range also offers low maintenance costs without compromising on performance, and exceptional durability thanks to the air-tight wet disc brake system. Users have a choice of

greater application flexibility. “It’s a fantastic option for warehousing,”
says Trevor. “The AE50 has so many features but essentially it offers substantial cost savings on energy and maintenance as well as outstanding performance, indoors or outside, and 24 hour/365 day capability – we think it’s going to satisfy the growing demands in the material handling industry.” Tel: 01376 520520
