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.

Following the success of electric car incentive programmes in Norway, a group of engineers, investors, and representatives from the maritime sector are teaming up to expand the use of electrically powered ships in the Nordic country.

“We supported research and development into electric cars in Norway, now we need to establish an innovation platform for the electrification of ships,” Sofus Gedde Dahl, Managing Director of Cavotec Norway, recently told Norwegian technology publication Teknisk Ukeblad.

The project, named ReCharge, is headed by leading certification and classification group DNV GL. Along with Cavotec, Port of Oslo is also partnering on the project, together with Enova, a technology- and data analytics-driven online lending company, which is contributing almost half of the project’s total NOK 1.45 million budget.

ReCharge will review the practicalities of expanding the availability of shore power at Norway’s ports, and research different power systems, such as battery-powered vessels and hybrids.

Shore power, or cold ironing, is the process of connecting ships in port to the electrical grid and switching off their engines. This reduces emissions of NOx, SOx, and particulate matter.

Cavotec has extensive experience of the design, manufacture and installation of high and low voltage ship-based, shore-based, and mobile shore power, or Alternative Maritime Power (AMP) systems. The Group first started working with AMP in the 1980s in Sweden, and has since supported customers worldwide with the technology.

The Group also developed the world’s first combined Cavotec MoorMaster™ automated mooring and AMP system for two passenger ferry berths in the Norwegian fjords. The AMP system in this application recharges batteries aboard a battery-powered passenger ferry.

ReCharge conveners say that they want to see Norway become the world leader in environmentally friendly ships. And while Norway is not an EU state, improved availability of shore power would keep it in line with conditions of an EU directive which requires all ports in the 28-member bloc to make shore power available by 2025.

“Charging options are critically important for batter-powered ships and plug-in hybrid vessels. Shore power will therefore play an increasingly important role in port infrastructure of the future,” says Project Leader Hans Anton Tvete, DNV GL.

According to DNV GL, some 40 hybrid ships are on order for Norwegian shipping lines, with a similar number of plug-in hybrid vessels also due to enter service in the coming years.

Organisers have also stressed the role of government support in expanding the availability of shore power.

“To establish shore power and associated infrastructure, we need the support of central government. The development of infrastructure is critical. Shipping lines want to see a return on their investment within a relatively short time scale,” Bjørn Vartdal, Programme Leader for Maritime Research at DNV GL told Teknisk Ukeblad.

On the technical side, Cavotec points out that despite the difference between voltages used by many ships, (60Hz), and on land, (50Hz), it is possible for growing numbers of vessels to connect to shore power.

“If we pool our expertise with fellow suppliers, customers and other stakeholders, I believe that we have the necessary technical know-how and insight to significantly broaden access to shore power,” says Gedde Dahl.

Cavotec recently co-hosted the opening of the what is believed to be the first shore power application for offshore vessels in the Norwegian port of Bergen.

Shore power facility for offshore ships goes on line

Along with Schneider Electric and the Port of Bergen, we recently hosted the opening of what is believed to be the world’s first shore power facility for offshore supply vessels.

The Skandi Vega connects to shore power at the Port of Bergen.

Luciano Corbetta, Sales Director for our Ports & Maritime unit, also joined other industry experts, environmental organisations as well as local and global media for a series of seminars and in-depth case studies.

During the opening ceremony, which saw the Skandi Vega connected to the Norwegian power grid, local officials announced NOK 2.5 million in increased funding for the introduction of shore power at the port. Earlier, Inge Tangeras, CEO of the Port of Bergen, told delegates: “The future is electric.”

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 ships’ crews to switch off vessels’ diesel-fired engines, thereby reducing emissions in ports and surrounding communities.



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.

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.

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.
