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.

Electrification, automation drive port and ship projects

Last week we announced a series of projects with ports and shipping lines involving our innovative electrical supply and automated mooring systems.

Salalah has used MoorMaster™ at various berths for many years.

Salalah has used MoorMaster™ at various berths for many years.

The largest of these project is for eight MoorMaster™ automated mooring units for the Omani port of Salalah, which has already been using MoorMaster™ at a number of different berths for several years.

MoorMaster™ is a vacuum-based automated mooring technology that eliminates the need for conventional mooring lines. Remote controlled vacuum pads recessed in, or mounted on the quayside or pontoons, moor and release vessels in seconds.

MoorMaster™ has completed more than 100,000 mooring operations to date at Ro/Ro, container and bulk handling and lock applications worldwide.

Click on the link below, and you’ll see MoorMaster™ in action at the St. Lawrence Seaway in Canada.

We’re also encouraged to see a number of orders for one of our latest innovations: our Automatic Plug-in System (APS). APS automates the electrical power and communication connection of cranes, ships and other mobile equipment to the power grid, thereby expanding the use of mobile electrical equipment. The system delivers cost savings, environmental benefits and improved safety standards.

At DP World’s major development at the Port of Yarimca in Turkey, we’re set to supply APS equipment that will provide electrical power and communication connection for Electric Rubber Tyred Gantry (ERTG) cranes. And in another project at the same port, we’re supplying Konecranes with APS equipment that will be installed on 18 ERTG. And for one of the largest container terminals in Portugal, we’re supplying APS for 11 ERTG.

And for a new container terminal in Surabaya, Indonesia and in Melbourne, Australia, we’re supplying a total of 22 cable reeling systems for Automated Stacking Cranes.

Elsewhere, for a major European shipping line, we’ve won a substantial order to supply Alternative Maritime Power (AMP) reel systems for nine new-build container ships. We’ve also been awarded a similar order for AMP equipment that will be installed on five container vessels for a Chinese container line. Our AMP systems reduce vessel emissions in port thereby helping to improve air quality in surrounding communities.
