Cavotec co-hosts shore power event in Bergen

Cavotec co-hosts shore power event in Bergen

Cavotec, Schneider Electric and the Port of Bergen are hosting a major event on shore power next week which will gather leading experts to discuss how the technology is playing an increasingly important role in reducing emissions at the world’s ports.

On Tuesday, June 16 delegates will gather in Bergen to consider key aspects of global shipping’s use of shore power, including the latest developments in shore power technologies, how changes in regulatory frameworks are affecting the application of shore power, and the challenges that exist for its wider use.

Cavotec’s Luciano Corbetta, Sales Director for our Ports & Maritime unit, will join other industry experts, environmental organisations and local and global media for a series of seminars and in-depth case studies.

Shore power – also known as Alternative Maritime Power (AMP), cold ironing, and High Voltage Shore Connection (HVSC) – is the process of connecting ships in port to land-generated electrical power. This allows vessels’ diesel-fired engines to be switched off, thereby reducing emissions in ports and surrounding communities.

We will also be hosting a port visit during which attendees will see Bergen’s shore power installation at first hand. Furthermore, the event promises to be an excellent opportunity to meet colleagues and network with fellow ports and shore power professionals.

Cavotec is a leading supplier of innovative shore power technologies. Our AMP systems are in use at a large number of low and medium voltage ship- and port-based applications worldwide.

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 powers battery-driven passenger ferry

The glorious waters of the Swedish capital are a little cleaner today, and a little quieter, thanks to one of our innovative shore power systems which is being used to charge a battery-powered passenger ferry.

At the ready: the Cavotec AMP cable unit.

At the ready: the Cavotec AMP cable unit.

The project involves Echandia Marine and global engineering group ABB. Cavotec has supplied a cable reel, a connector and a radio remote control (RRC) unit for a system which charges 34 battery packs on board the E/S Movitz, a small passenger vessel which ferries commuters and tourists around the islands of central Stockholm.

The Cavotec motorised cable reel and connector ensure the safe and efficient transmission of electrical current, (DC), from land, while the system itself is remotely operated by a Cavotec RRC 2-3 unit.

Two electric motors, or pods, provide propulsion and steering for the ferry, and generate 125kW of power. On a single charge, the vessel can operate for up to 90 minutes. The Movitz also has two diesel generators on board as back-up in the event of battery failure.

The ferry can even be fitted with solar panels or fuel cells. Emissions from the Movitz are therefore virtually nil, compared to 300 tonnes of carbon dioxide, three tonnes of nitrogen oxide and 160kg of particulate matter which the ferry generated in the past using conventional diesel propulsion.

Furthermore, the only sound on this ferry are passengers chatting and waves lapping around the hull.

This application shows how emissions can be cut effectively and efficiently. How’s your Swedish? If it’s good, you can read more about this application on ABB’s website here.

Partnerships strengthened in port equipment orders

The world’s leading crane manufacturers, port operators and ship owners continue to rely on Cavotec to meet growing demands for advanced crane technologies and innovative shore power systems. A number of recent orders, (announced at the end of March), amounting to a total of €10 million attest to this.

For the Pasir Panjang Terminal at the Port of Singapore, the most advanced terminal in the world’s second busiest port, the Group has been awarded a total of five orders. The most substantial of these is for cable reels that will supply electrical power to 72 ZPMC Automated Stacking Cranes. Another ZPMC order will include the largest power and spreader reels ever manufactured by Cavotec Spec- imas, one of Cavotec’s eight Centres of Excellence. The reels are designed for four ZPMC STS cranes destined for the Port of Genoa, and demonstrate significant advances in meeting growing customer requirements in terms of scale, performance and technical complexity.

“These projects highlight the degree of co-operation Cavotec enjoys with equipment manufacturers, and the world’s largest port operators, as a preferred supplier of a variety of innovative, mission-critical systems,” says Ottonel Popesco, Cavotec CEO.

Cavotec shore power unit selected for simulator

Ships’ crews need to sharpen their skills from time to time, and we’re delighted to be involved in a new training facility in Sweden – the first of its kind anywhere in the world – where mariners will be instructed in how to connect ships to shore power.  

Chalmers University of Technology has installed a shore power connection simulator on former bulk carrier MS Fryken in Gothenburg. Staff from Chalmers University will train captains and crew new to shore power, as well as provide instruction for staff on vessels which already use the technology.

The construction of the simulator is in part a response to shore power requirements set to be introduced by the Swedish Transport Agency, and in part to meet the growing use of shore power by shipping lines which are increasingly seeing the benefits of switching off their ships’ engines in port and connecting to shore power. The training course is mandatory for all personnel who handle shore power systems.

Shore power – also known as Alternative Maritime Power (AMP), cold ironing, High Voltage Shore Connection (HVSC) – is the process of connecting ships in port to land-generated electrical power. This allows ships’ crews to switch off vessels’ diesel-fired engines, thereby reducing emissions in ports and surrounding communities.

The simulator – fitted with a Cavotec AMP connection mechanism – will be used to train crews in how to connect their vessels to the high voltage cables needed to power ships in port.

Mega-connection: the simulator instructs crews on how to connect 2-3MW cables to land-based power sources.

The simulator shows crews how ships are positioned in relation to shore power units, and how to safely connect cables to ships, which involves correctly connecting 2-3 Megawatt cables with land-based power sources.

Our Swedish readers can read more about the simulator here. And you can see one of our AMP systems – AMP Mobile – in action at the Port of Los Angeles here.

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.

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.
