DROMEC supplied electric spudpole systeem for DAMEN Shipyards Gorinchem the Netherlands

Together with Damen, a system has been realized in which the safety of the users on board was our highest priority

DROMEC has developed a user-friendly system together with Damen to be able to safely handle 2 spud poles, each with their own weight of approximately 85 metric tons and a length of 30 metres, and to be able to freely change positions on the barge. Each pole can be driven into the ground with 160 tons to anchor the crane barge in a stable way and keep it in position so that the 625 tons crane on the barge can work safely. The system works on the principle of rack and pinion.

Plug & Play system

The 4 spud pole stations are linked to a central control system that monitors and guarded all stations. Each station is equipped with a control console so that the handling and operation of the pole can be done locally and the operator has a direct view of the loading and unloading of the pole.

Software

The main controlsystem runs on a Dromec inhouse developed software platform, on which all safety functions are monitored and guarded.

System specification per station:

• speeds 2 & 4 m/min
• workload 80 mT (nominal)
• peak workload 160 mT (peak)
• protection class IP67
• 2x mechanical securing device
• 2x electromagnetic holding failsafe brake
• sensors for pole status & position
• absolute encoders for position monitoring
• siemens 7 inch comfort panel for alarm and system status display
• modbus communication with 625 mT crane
• 4x stainless steel local control cabinet with functions:

– emergency stop
– green LED “System Ready”
– red LED “Alarm”
– push button “pole up”
– push button “pole down”

Dromec and Gleistein are pulling the right strings

If two companies are pulling the strings in their sector, it is Dromec and Gleistein. One in the field of drives and winches, the other with ropes, lines and cables in all shapes and sizes. Dromec developed two new and advanced test benches for the rope factory in Slovakia. Without the right tension, there is no right quality.
Eerde Warnaar from  company Gleistein explains it perfectly in the video below!

Gleistein from Germany, which hopes to celebrate its bicentenary in 2024, is the number two in Europe in the field of rope production. A family business, which is now run by the eighth generation. Gleistein manufactures ropes for applications in the offshore, maritime sector, heavy and industrial lifting, water sports and playgrounds. Every day, a total of more than 45 kilometers of rope rolls out of the production locations in Bremen and Slovakia. More than 5000 different types of ropes are in the range, varying in thickness from 0.3 to more than 360 millimeters.

Pre-stretch

‘A newly produced rope must first become stiff through use,’ says Eerde Warnaar, Senior Application Engineer and Business Developer at Gleistein. ‘When there is tension, the rope stretches slightly. A material like nylon can generate as much as 18 percent stretch. There are customers who require a maximum tolerance of 1 centimeter. That is why we must be able to calculate exactly how long the stretch length is at a certain tension force (the so-called pre-stretch). And then correct that to the desired actual rope length.’

Measuring = knowing. Gleistein has two very heavy test benches of 300 and 30 tons to analyze the pre-stretch. The company has ordered two new ones from Dromec: 100 and 10 tons. They are completely custom designed, with full digital programming and automatic winches. The software can also be controlled and programmed remotely. Clever in case there is a malfunction in the system. A laser measures the lengths and the tension forces, without any chance of deviations.

Tracing Rope Breaks

‘These test benches also offer a solution for tracing the causes of rope breaks. Because we repair broken ropes if it is economically rewarding and technically justifiable. Strands can be spliced ​​and tied together. No two ropes are the same, apart from the uses. Each rope has its own construction and materials.’

That Dromec was awarded the order did not come out of the blue. ‘Gleistein previously had large winches and coils made in Rhenen. I have known Cees Drost, the CEO of Dromec, for fifteen years. Their service is always excellent. Together with the client, they work neatly on a tailor-made solution. That always gives confidence and a sense of satisfaction.’ The development of the test benches took fourteen days, while construction was completed in three months.

New winch with controls for DEME Building Materials BV Vlissingen

Traditionally, Dromec has had a strong connection with the offshore and nautical sector. It is therefore not surprising that the Zeeland based construction and machine builder P. van Eijzeren and Dromec have found each other. An existing conveyor belt has been converted and it again complies with current legislation and regulations.

Project DEME Building Materials conveyor belt

P. van Eijzeren – based in Borssele and Zierikzee and founded in 1919 – specializes in agricultural mechanization and in construction and machine building, including engineering, machining and assembly.

‘Dromec uses us as a supplier for all kinds of sheet metal and steel parts. We also produced winchdrums for them’, explains project engineer Bram Steendijk. ‘The project for DBM Vlissingen-Oost was considerably larger.’

 

Winchsystem for conveyorbelt

Storage and transhipment company DBM Vlissingen-Oost knocked on their door to modernize a conveyor belt with which inland vessels are loaded with sand, stones and gravel. ‘The height of that belt in relation to the ship had to be flexible. Adapted to the size of the ship and moving with the tide. To raise or lower the conveyor belt, a winch system was needed. The skipper operates the belt.’

 

 

Matching 3D Model

The winch, control & software, hoisting cable and associated pulleys come from Dromec’s design department and workshop. P. van Eijzeren was responsible for the adjustments of the conveyor belt and the construction in the port of Vlissingen. The entire construction was, of course, extensively tested in practice. The development process – from the first sketch to commissioning – took six months.

Good communication and cooperation

The mutual communication and cooperation is excellent. ‘Because of the big distance, we mainly communicate by telephone and e-mail. That was always done in a pleasant and clear manner. The Dromec winch 3D model fitted neatly into our conveyor belt design model. The work and time schedule were neatly drawn up. I know that our customer is very satisfied with the end result. That functions properly. In short, it was a great service & co-operation!’

It was a fervent wish of Wubbo Ockels to go into space. That dream came true. And that is now also happening with the revolutionary energy kite, the project with which the astronaut experimented as a professor at TU Delft. The Delft start-up Kitepower is building on his great legacy and has now developed a mature and usable system for the market. Thanks to an important contribution from Dromec.

From vision to reality. Electricity is generated via a dynamo by unrolling a cable, which is connected to the circling kite. So pulling force is converted into current. An autopilot enables automatic take-off and landing. An extremely durable and efficient system. Dromec designs and builds the ground stations – with winches for the kites up and down movement cycle.

Winch

‘Wubbo was my graduation professor and a tireless advocate of sustainable energy, recalls CTO Joep Breuer. ‘Thanks to a European subsidy, we were able to convert his ideas into a commercial company for kite wind energy in 2016. We soon arrived at Dromec, after which the first winchsystem was developed. Later an improved version with a larger kite was realized. The results of the flights are very satisfactory. The collaboration with Dromec is excellent. They make beautiful technique and supply high quality materials. While brainstorming, we learn from each other. It’s great to work towards perfection together.

Only a handful of companies in Europe are engaged in energy kites. As a pioneer, Kitepower is one of the leading companies in this market. The company works with the top ten best kiters in the world. The inventors from Delft are doing a great job. In August they started a crowdfunding campaign with the goal collecting €700.000,- For all info about this crowdfunding campaign see foolowing link crowdfunding

Six years of research resulted in two working prototypes. After three successful pilots – one with Defense – and nine versions of our Kitepower system, we are ready for the next phase: bringing our AWES to the international market. AWES is the first mature and functional mobile airborne wind system. One ground station (built in a 20 ft standard container size) with kite will supply up to 150 households with electricity (100 kW per year). In the future we want to expand that to 500 kW.’

Defence

Today, the call for Kitepower’s innovative technology is louder than ever. Exploding energy prices, Russian gas cut off, extreme weather conditions due to climate change: current events prove it. ‘We still have to compete with wind turbines. But kite wind energy uses 80 to 90 percent less material than wind energy and has a longer lifespan. And there is no horizon pollution, annoying shadow effect and noise disturbance with our system. Now the two systems complement each other. Ultimately, we want to make ours more profitable and offer a serious and greener alternative to classic windturbines. A comparison with solar energy: our Falcon with a kite area of ​​60 square meters produces as much energy as 2000 square meters of solar panels.’

Energy kites are ideal in compact areas where wind turbines cannot or are not allowed. Kitepower fits worldwide. Particularly in deprived and inhospitable regions without power plants, places where natural disasters shut down energy supplies, at field hospitals in war zones. Farmers and companies in developing countries will benefit from it. So kite wind energy also serves a great social purpose. It definitely has the future.

Dromec is proud to be part of this development. In addition to the Kitepower systems, Dromec designs, develop and builds several solutions for the so-called renewables (green energy). Systems for pulling cables for installing offshore wind farms, pull-in systems for main offshore power cables, wind turbine service winches, etc. In addition, Dromec is the inventor of floating solarpannel islands that follow the sun, in the market known as Floating Solar.

In close cooperation with Kooiman Marine Group and Van Oord, Dromec developed, build and supplied 2x Active Heave Compensated 30 mT winches for Van Oords new hybrid water-injection dredger Maas.

Besides winches, Dromec also supplied the AHC controls, software and integration to the Van Oord HMI system (VOCAM). The winch system is an important part of the innovative hybrid energy management system that reduces harmfull CO2 emissions and meet the IMO TIER III regulations.

During dredging, the winchsystem feeds back re-generated energy into the ships powergrid where it is used for propelling the diesel-electric engines. Compensating  ship movements caused by waves is realized by Dromec’s software platform in combination with a high speed winch control system.  During dredging operations data as position, speed and torque are monitored & guarded by the winch controls. The AHC system enhances the positioning of waterjets that results in more precise and higher efficient pre-programmed dredging operations. Dromec commissioned the complete set to make sure Maas was ready for first dredging job on river Thames in London (UK).

For Deme Group, Dromec engineered and build this special Recovery winch for Deep Sea Mining ROV (Remotely  Operated Vehicle).

This winch is applied for recovery of ROV during deep sea mining operations. Because of the dimensions and weight of this winch, the assembly & transport is performed by our partner company  De Meyer
