Cavotec gears up for Offshore Technology Days

Cavotec gears up for Offshore Technology Days

Ready for the off(shore): the Cavotec team at a recent OTD

Our offshore technologies experts are preparing for the Offshore Technology Days (OTD) trade show which gets underway tomorrow at the home of the Norwegian energy industry Stavanger.

The team will be showing how our innovative technologies – Radio Remote Controls, (EX and non- EX), Gessmann joysticks, hose and cable reels, onshore Alternative Maritime Power solutions for offshore vessels, connectors, and drag chains, (nylon and steel) – are helping our customers operate efficiently, safely and cleanly in some of the most demanding environments on Earth.

If you are one of the 30,000 visitors heading to the exhibition, don’t forget to meet the Cavotec team at stand 2400 in Hall B.

Attracting engineers, technical specialists, industry leaders and experts, OTD is now in its 17th consecutive year. With more than 500 exhibitors expected this year, organisers claim that OTD is one of the fastest growing oil exhibitions in the world.

Cavotec turnkey RRC package for steel plant

In the latest development for Cavotec turnkey radio remote control (RRC) technologies, our innovative RRCs are being used to operate a bulldozer at a BOSS steel plant in Port Talbot in the UK.

New and improved: the bulldozer rigged with our RRC unit.

New and improved: the bulldozer rigged with our RRC unit.

Our comprehensive system enables the operation of the machine where previously personnel were required to work in a highly hazardous environment.

The vehicle collects molten steel that spills from a 20-foot ladle during the steel mixing process. Such spillages are common, and this material needs to be quickly removed before it hardens. Our system enables its removal, while also keeping personnel at a safe distance from the ladle. In this highly demanding environment, reliability is key.

Teaming up with a third party integrator, we have supplied RRC units as part of a complete turnkey solution. Together with our fellow supplier, we have converted the bulldozer to enable full remote operation.

This process included the conversion of the vehicle’s conventional hydraulic system into electro-hydraulics. Having supplied a large number of systems for converting conventional cab-operated machines to radio remote operation, we plan to develop and expand this package offering.

The technology is proven, and our systems can be readily adapted for use on multiple vehicle platforms as well as machines ranging in size from extremely small to very large.

Cavotec drag chains drive bridge behemoth

What’s 57 metres long, weighs 200 tonnes and will link a floating hotel with oil platforms? Answer: the world’s longest offshore telescopic bridge. The bridge, built by Marine Aluminium, will be a walkway between specialised accommodation vessel Edda Fortis and oil installations in the North Sea. 

This highly specialised unit – powered by our advanced cable chain systems – will initially see service in the North Sea, but is designed to be readily adaptable to a variety of different applications.

The walkway section of the bridge is primarily made from aluminum, with just a 10 per cent steel content, making the structure light but durable.

Cavotec drag chains drive world's longest telescopic bridge

Bridge beast: the world’s longest telescopic walkway.

Pioneering project

This is the first time that Marine Aluminium has delivered a telescopic pedestal. It will be mounted on the vessel together with a winch system and can be raised and lowered as required.

Compared to conventional walkways, this bridge requires a large amount of hydraulics and management systems. Our drag chains ensure uninterrupted rotational, vertical and horizontal movement.

You can read more about this unusual application (in Norwegian) in Teknisk Ukeblad. And here’s news of another recent offshore energy project where our drag chains played a critical role.

Cavotec secures Sandvik order in Brazil

Cavotec has won a milestone order from mining equipment supplier Sandvik for four large level winder reels (see image below) for an application in Brazil.

The end-customer is global mining group Vale. These large units, capable of reeling 2,000m of cable, will be designed and manufactured by Cavotec at its facility in Shanghai.

This project will serve as an excellent reference for Cavotec and its Mining & Tunnelling unit in Brazil and beyond.


Gullfaks B drag chain project underway

Gullfaks B drag chain project underway

Cavotec’s largest oil and gas project to date – upgrading Statoil’s Gullfaks B drilling platform – is now fully underway and is proceeding well. 

Our engineers recently began work on the installation, one and a half months ahead of schedule.

The guide system for one chain system is now mounted, and our customer, Aibel, a leading engineering, construction, upgrading and maintenance service provider in the oil, gas and renewable energy sector, is happy with progress.

Cavotec is supplying, testing and commissioning three sets of stainless steel drag chains as part of a of a major modernisation programme that will extend the operational life of the Gullfaks B platform to 2032.

Cavotec supplies advanced power control and automation technologies to a wide variety of offshore energy customers worldwide.

Cavotec radio remotes pack a punch

Here’s news of another of our radio remote control (RRC) applications, this time with units that control the flow of explosives from tank trucks to boreholes via hoses.

Fire in the hold: 395 boreholes packed with explosives

Fire in the hold: boreholes are packed with explosives.

At this construction site in Sweden, the units ensured that 300 to 400 boreholes were safely filled with 30-40kg of explosives. Special features on these, (and on three other trucks), include an ‘AD TWIN’ system that boosts the maximum range of the units. The need for a reliable, long-range radio link is considerable, especially in these sorts of applications.

The units’ displays also provide operators with data on the amount of explosives in any given borehole, the total amount of explosives in all the boreholes, and pump pressure. All these are easily selected by the operator at the push of a button on the terminal unit.

Full control: a Cavotec MC-23 RRC unit ensures safe operations at all times.

Each truck is supplied with two identical systems which allows two operators to fill explosives simultaneously from one truck. We have supplied four trucks with this system for this customer, and are set to upgrade several other vehicles with similar equipment.

Cavotec RRCs are used at a wide variety of applications all over the world. Amongst many others, notable applications include operating traffic systems, equipment on deep sea drilling rigs and to even help clear unexploded munitions. The units are also used to operate our MoorMaster automated mooring system.
