2,500 kW variable speed, super synchronous subsea
motor operates at speeds ranging from 2,500 to 4,000 rpm

Hayward Tyler Ltd, a leading manufacturer of pumps and motors for the power and oil and gas industries, recently delivered three of the largest subsea motors ever built. The 2,500 kW subsea motors were ordered by Aker Kvaerner Subsea, a leading provider of surface and subsea solutions for the oil and gas industry, to drive its seawater injection pumps on the StatoilHydro Tyrihans project in the Norwegian Sea. The motors have been developed in close cooperation with Aker Solutions.

The qualified Hayward Tyler design for the 2,500 kW variable speed, super synchronous motor will operate at speeds ranging from 2,500 to 4,000 rpm. The subsea motors will have increased insulation (11 kV) to accommodate the electrical challenges faced by the world's largest subsea motor and longest step out (31.4 km) from the Kristin platform.

Mark Wood, Group Sales and Marketing Director, Hayward Tyler stated: "Hayward Tyler is proud to have built and delivered these extraordinary motors and to be involved in such an important project. Building the motors is a significant achievement for the company in terms of technical challenges and engineering capabilities and we look forward to the new challenges that lie ahead to further develop our motor technology."

Offshore winch pulls both ways

A J D Neuhaus air operated winch has been successfully deployed on the AWG/1 drilling rig operated by Nederlandse Aardolie Maatschappij BV (NAM) in the Dutch North Sea sector.

The winch is a Profi Puller 1800 model, fitted with a split winding drum and is used for hauling loads on a flatbed wheeled trolley running in a guidance track over a connecting bridge between the production and compression platforms. The trolley has a load capacity of 7 tonnes, with the single winch pulling loads in both directions across the 40 metre long bridge. With the winch situated at one end of the bridge and a reversing roller at the opposite end, a positive pull force can be exerted on a loaded trolley when traversing in either direction over the connecting bridge.

The Profi Puller 1800 winch, fitted with a split winding drum, pulls both ways.

The split winding drum on the winch has one drum paying-out the wire rope at the top (which is connected to the side of the trolley) while the other drum reels-in at the bottom (with the rope connected to the opposite side of the trolley after passing over the reversing roller). This sequence of paying-out and reeling-in is changed when the direction of the rotation of the winch is reversed. Loads traversing the exposed bridge causeway are always tethered at each end for maximum safety, with the attached wire rope always in tension from the direction of the pulling operation.

JDN winches designated for offshore duties are also subject to paint finishes designed to provide a high level of protection against adverse weather conditions and general exposure to marine environments.

With air operated motors providing the power, the JDN equipment is suitable for operation in hazardous areas and as standard carry a rating of Ex II 2 GD T4(x) / II 3 GD 11B T4(x). Increased spark protection can also be provided for a rating of EX II 2 GD 11B T4(x).

JDN winches can be supplied for lifting and pulling operations with capacities from 1200 to 3000kg. They combine variable speed operation with maximum reliability and minimum maintenance, even at 100% duty cycles. They offer high rope wire capacities, with an ideal ratio of drum/rope diameters which ensures long rope duty cycles. Highly durable steel structures, with optional pulling frames for rigidity and durability are further enhanced by ease of installation and low operating noise levels.

BOP handling systems, suitable for landbased or
offshore oil and gas exploration and production platforms

BOP handling systems, suitable for landbased or offshore oil and gas exploration and production platforms can be supplied by J D Neuhaus. These products can be offered with pneumatic or hydraulic operation for the lift, lower and traverse operations, making them ideally suited for installation in hazardous or other potentially explosive environments.

A BOP handling system comprises twin matched hoists used in conjunction on parallel overhead rails. Systems can be provided with joint lift capacities from 20 to 200 tonnes. Where limited headroom conditions occur, then ultra-low monorail hoists offering combined lift capacities from 8 to 24 tonnes can also be supplied. (Refer to picture on the right).

These products comply with international standards including AP1 7K, ABS, ANSI B30.16, DNV Approval Programmes and NORSOK, together with 3.1B certification on load carrying parts, and backed-up by a worldwide service network. The hoists incorporate overload protection adjustable from 90 to 125%, with a load safety factor of 5:1, dynamic factor of 1.33 and tensile strength rating of 2.5. In addition, traceability is provided by the JDN unique parts marking system.

J D Neuhaus also provide instructions for the safe installation and operation of their BOP handling systems. This document includes information regarding the selection and reinforcement where necessary of the overhead runway beams, together with the positioning, spacing and alignment of hoists for optimum operation. The need to use lift points located on the BOP which are above its' centre of gravity, and the need to keep trolley drives and beam flanges clear of drilling mud are indicated. The need for preventive maintenance and adequate lubrication to combat the effects of seawater and excessive component wear is also highlighted.

Boll launches new automatic filter for fuels, lubricants & coolants

Bollfilter has launched a new automatic filter system to protect valuable plant and machinery from the risk of damage from solids contamination - the Boll 6.72.

The Boll 6.72 Automatic Filter is designed for the filtration of particulates from heavy fuel oil and lubricants for mobile and stationery diesel engines as well as coolants and wash water in automotive industry machining and part washing processes.

Manufactured by Boll & Kirch, the leading European manufacturer of automatic filtration systems, the 6.72 - like the rest of the Boll automatic range - is designed for efficient operation, low maintenance and high performance.

New Features
The Boll 6.72 Filter incorporates a number of important improvements in both design and function.

The new housing is more compact, reducing the space required for installation, and its robust design, with even fewer moving parts, improves durability and reduces maintenance.  Perfect synchronisation of the back-flushing process by means of a double acting air/flushing valve, makes the self-cleaning process even more efficient.

The Boll 6.72 Filter is available in three sizes: DN40, 65 and 80 with a choice of filter element tpyes.  Backflushing can be controlled by differential pressure or time, with filtration down to 6 micron.

The 6.72 Range
The Boll 6.72 Filter is available in three sizes: DN40, 65 and 80 with a choice of filter element tpyes.  Backflushing can be controlled by differential pressure or time, with filtration down to 6 micron. All sizes are available with a manual standby unit connected by a  2 stage 3 way valve, the model 6.72.1

Comprehensive support
Bollfilter Protection System are supplied by Bollfilter UK, which offers UK customers full technical support, including system design, commissioning and contract maintenance.

Converting a low cost single point
cam into a cam for a 3 point locking system

How often do we see greater flexibility for less cost? Well, EMKA's new 3 point cam adapter offers just that. It converts a low cost single point cam into a cam for a 3 point locking system. This gives enclosure manufacturers a much reduced stock requirement for varying cabinet door sizes, typically leading to a 40% reduction in stock costs on this component type.

OEM/Specialist cabinet producers up to now have needed to stock both single and 3 point cams, but now need only stock the popular and low cost single point item with a small quantity of adapters. The 1000 cam adapter is a precision zinc die component suitable for the complete range of EMKA 1000 ¼ turn locks where the standard single point cam is appropriate.

Fixing is a single bolt operation and may be carried out in cabinet manufacture, at installation, or as a retro-fit, by removing the cam fixing bolt and refitting, then installing the rod system to the door, thus providing two more closure points for improved sealing and security on longer doors.
