The EH Handle offers an escape release option as standard, ensuring the safety of operators at all times. It also has lock-out features and can support up to four padlocks with a shackle diameter of 8mm.

Cased in stainless steel or zinc alloy depending on the application the EH Handle is easily installed or retrofitted, accommodating differing door thicknesses and a misalignment allowance of ±12 mm.

Fortress Interlocks has specially designed the EH Handle to be discreet and particularly useful for applications using small radius hinged doors in harsh environments. The EH Handle forms part of the amGard range of safety interlocks, a modular, heavy duty interlocking range that provides both safety and security by controlling access to dangerous machinery and safeguarding personnel. A variety of actuators and adaptable mounting arrangements helps sustain a long life cycle and minimizes downtime.

The Swedish Coastguard service has selected a Crowcon gas detector for one of its newly constructed hovercraft. The flameproof (Exd) infra-red Nimbus fixed gas detector and Gasmaster control panel were installed on the craft by Griffon Hoverwork of Southampton on the UK’s south coast.

The hovercraft will carry two Ski-Doo snowmobiles in the cargo bay, which will be used for emergency rescue services during the winter months. Because of the danger of petrol vapour leaking from the snowmobiles, it was necessary for the cargo bay to be fitted with a reliable hydrocarbon gas detector and control panel. As the cargo bay is usually closed, these vapours could reach concentrations hazardous to human health.

The Swedish Transport Authority has other Crowcon gas detectors in its coastguard fleet, including ships, so when it came to commissioning a new hovercraft from Griffon Hoverwork, it expressly requested that Crowcon detectors should be installed.

“We are delighted that the Swedish Coastguard has decided to install one of our units in their new hovercraft,” commented Crowcon Fixed Systems Product Manager Andy Avenell. They already use many of our gas detection systems in their existing fleet and it is testament to the quality and reliability of our equipment that they keep coming back to us for more units.”

If the Nimbus detector registers dangerous levels of petrol vapour, ventilation and alarm systems are automatically triggered by the Gasmaster control panel. In addition to this, a local external status light which shows, at a glance, if the unit is in normal function or in fault.

The rugged detector is designed to operate in the dirtiest, harshest conditions. The optics will operate up to 90% obscuration, and at 75% obscuration a ‘dirty optics’ warning appears on the Gasmaster control panel, informing operators that the optics need cleaning. The Nimbus is extremely simple to use, even in inaccessible areas. A duct mounting plate is available, incorporating a remote gassing port, which allows calibration checking without requiring entry into the duct.

Following the success of its shallow-water real-time imaging sonar, the Gemini 720i, Tritech has launched a deep-rated version, the Gemini 720id. Now available in 300m and 4000m versions, Gemini is a forward-looking sonar which utilises an array of transducers to provide a 120º field of view, for a real-time sonar image of the underwater scene ahead.

With its high-resolution specification, Gemini has near-field focus capability ideal for very short-range manipulator work as well as very long range target detection. Gemini sonars can be easily integrated with a variety of ROV and AUV platforms.

Gemini is the technology for subsea sonar vision. As the next generation in real-time multibeam imaging sonars, Gemini has quickly captured the global subsea market; most recently achieving a nomination for the Subsea UK Innovation and Technology Award.

Gemini’s rapid and dynamic visualisation of the underwater scene makes it perfect for deep-water applications where successful navigation and obstacle avoidance is required. Gemini provides instant feedback on changes happening in the underwater scene, which reduces overall operation time and increases ROV effectiveness.

Chris Echols, VP of North America, Ashtead Technology Offshore (US), comments: “Ashtead Technology Offshore is extremely excited to be the first to present, to the rental market, the latest generation of 2D multibeam sonar technology in the Americas region. We believe this will revolutionise the way ROV service contractors navigate in low visibility situations because of the Gemini’s wide field of view and real time imaging capabilities.”

Dave McKay, Specialist Subsea Services (UK) also comments: “As an ROV contractor, we have been delighted with the performance of Tritech’s Gemini sonars. The Gemini was fitted to one of our Triton XLS 150hp work-class vehicles for a well-abandonment project and most recently in power cable lay and cable pull-in operations. In both these operations, the Gemini’s real-time field of vision allowed us to have a clear view of the underwater scene, which assisted our client field operations to run smoothly and more efficiently.”

Pressure relief specialist Elfab has become the first manufacturer to offer a rupture disc protected by a three-year warranty. Since its launch in 2004, Opti-Gard™ has proved so robust and reliable in operation that Elfab is offering a three-year warranty as standard on Opti-Gard ™ discs supplied after 1st January 2011*.

The Opti-Gard™ system comprises a reverse-acting rupture disc, a single-design holder with multi-flange compatibility and a non-invasive, ATEX-approved burst detector, Flo-Tel™+. Featuring an industry-leading tolerance of only three per cent across a wide range of burst pressures and a 95 per cent operating ratio, Opti-Gard™ offers the highest performance characteristics available for liquid, gas or vapour applications.

Opti-Gard™’s performance has allowed the optimisation of process pressures for many of Elfab’s customers. Apart from lowering re-supply costs, this has reduced disc inventories by up to 60 per cent.

* Please refer to www.elfab.com for terms and conditions of warranty.
