DROMEC Winches develops 3 electric winch systems

Ampelmann delivers safe and efficient offshore access solutions to the global offshore energy sector. Its portfolio of modular and energy efficient gangways is tailored to meet every local and global demand, providing reliable and consistent access to offshore installations in a variety of sea states and weather conditions. In collaboration with the engineers at DROMEC Winches, Ampelmann has developed 3 electric energy-efficient winch systems.

Energy Efficiency

Ampelmann previously used hydraulic transfer systems, employing a big power pack to operate cylinders and hydraulic hoisting winches. In this era of sustainability and energy conservation, Ampelmann approached the engineers at DROMEC Winches to jointly devise a more sustainable solution. This led to the electrification of 3 winch systems, resulting in a net consumption of 10% related to the previous big power pack, a significant reduction compared for the 31-meter-long gangway.

Kees-Jaap van Nes, Senior Project Manager at Ampelmann, says,
“I am very satisfied with our collaboration with Dromec. It’s a great product developed through excellent teamwork.”

Crane Hoisting Winch

The offshore vessel navigates to the wind turbine for various maintenance and operations tasks. An electric hoisting winch installed at the tip of the gangway enables the gangway to function as a crane. With a high nominal load, tools are hoisted to the wind turbine. To reduce weight, this winch is predominantly constructed with lightweight components. This upgrade allows the crane to transfer more equipment with a peak speed.

Telescopic Winches

The gangway features a telescopic extension system with 2 winch systems, each capable of exerting a powerful force. This system is fully redundant for safety and operational reliability. Operating under constant tension, the entire system is heavily utilized, even in seas with a significant wave height of 3.5 meters. With a peak speed, the gangway can extend and retract using the winch system.

Height Adjust Winch

At the base of the offshore vessel, there is a large winch, which raises the entire gangway to the required height. Powered by dual motors, the gangway can be lifted 15 meters. The redundancy of dual motors ensures operational reliability. It is possible to position the gangway using a single motor at a lower speed if needed.

Geerart, an engineer at DROMEC, says,
“With Ampelmann, we truly reach an optimum solution. We understand the technical aspects together and are capable of collaboratively improving for the future. The transition from hydraulic to electric power has significantly reduced energy consumption. Our alignment in terms of system control is also remarkable. There is mutual appreciation, and based on this initial design of the upgraded winch systems, more innovations will follow.”

DROMEC Constant Tension machines

DROMEC Constant Tension machines are known for their multifunctional spooling capabilities. These machines find applications in various market sectors, ranging from spooling and unspooling electrical cables to winding heavy tow wires for offshore vessels. Over the years, DROMEC has developed a diverse range of winches in terms of power and size.

Electric Drive

What makes DROMEC special is the deliberate transition to exclusively using electrically powered systems a few years ago.

According to Cees Drost,
“This transition has brought DROMEC two significant advantages. Firstly, we have reduced environmental impact by eliminating diesel emissions. Secondly, our machines can be controlled with much greater precision, allowing even highly sensitive umbilical wires to be spooled without risk, thanks to integrated data logging. Furthermore, our system offers the capability to generate electricity during the project itself. These machines are often employed in opposite position to other winches or reels, where customers require specific tension requirements. During spooling, we can switch the motor to act as a braking dynamo. This not only results in emissions savings but also energy savings, especially in situations where work is predominantly carried out indoors. In the absence of a power source at a project site, there is always the option to activate a small and energy-efficient generator, a requirement in less than 5% of projects.”

Tensioning

DROMEC primarily sees these machines being used in markets such as rigging companies, where long lengths are converted into customer-specific lengths for both steel and fiber ropes. Another application involves replacing steel cables on cranes and pile drivers, where old wires are first spooled onto an empty reel before the new or clean cable is wound under tension on the machine. DROMEC spooling machines are also widely used for wire inspection. In this process, wires are degreased, inspected, re-greased, and immediately spooled under tension on the winch, all in a single back-and-forth motion.

Customization

Upon request, DROMEC Winches can offer more extensive customer-specific features, such as Active Heave, line measurement, high-speed capabilities, or specific pulling forces. DROMEC spooling machines vary in pulling force, with the smallest machine having a pulling force of 60 kg, and the largest machine exerting a pulling force of 42 tons (at the core). For newly developed spooling machines, two essential parameters are always considered: the maximum weight of the reel within the machine and the desired pulling force. At DROMEC we are always up for this challenge!

DROMEC sponsors WIND

Seafarers’ charity has been supporting seafarers and their families for over 100 years. WIND, originally a maritime company, is dedicated to supporting their colleagues at sea. DROMEC is proud to support this cause, as our business activities also have a significant focus in the maritime sector.

WIND rents equipment worldwide. DROMEC Winches supplies various winch systems to WIND, which are used, among other things, for guiding a High Voltage Offshore Cable from the carousel. Before a cable layer can set sail with a full carousel, the cable often needs to be spooled onshore. DROMEC Winches has developed a winch system that can guide the cable under tension, ensuring it is neatly placed in the carousel and can be paid out at a later time.

For the Seafarers’ Charity Fund, WIND organized a challenge in the Lake District in England. Participants successfully climbed 24 peaks within 48 hours, covering 33 miles with a 13,000 ft ascent. And they conquered it!

DROMEC Winches constructs winch system for megadoor Smulders UK

Smulders is an international steel construction company operating in the onshore and offshore sectors. For a new production facility in Newcastle, DROMEC Winches at the request of ASAV lifting- and hoisting technology has developed an advanced winch system for an impressive megadoor.

Megadoor

The impressive production facility stands at a height of 36 meters and a width of 47.5 meters, equipped with a megadoor operated by two powerful winches on each side. The megadoor consists of steel panels divided into sections, hanging from the steel structure. The advanced winch systems effortlessly lift the panels upward or lower them downward, ensuring perfect alignment during opening and closing. Additionally, the winches can be operated independently for added safety or in case of a malfunction. The winch system has the capacity to hoist a weight of 135 tons on a single cable.

Winch System

The two winches are strategically positioned on either side of the megadoor. The cable runs up and over multiple pulleys on one side and descends to a fixed point on the other side. The system is precisely mirrored on the opposite side. Both winches operate synchronously to maintain the desired speed during the opening and closing of the megadoor. The winch system has a pulling force of 19 tons and can handle peak loads of up to 38 tons. In situations where the winches need to bear the weight or during emergencies, the system operates at a lower speed to ensure safety.

 

Jesper Becks from Smulders:
“The installation of the megadoor was a complex process that required a combination of technical expertise and practical experience. Given our specialization in steel construction, we relied on DROMEC as a reliable partner for the supply and installation of the electromechanical components. DROMEC handled the entire process, from the engineering of the winches and lifting mechanism to the installation. Transparency, flexibility, and safety were paramount at every step. Thanks to DROMEC’s technical knowledge and flexibility, the installation of this impressive 135-ton megadoor went smoothly. The successful and safe completion of the installation is a significant milestone in this project.”

 

Controls

Both winches can be easily operated using a control panel or a button. The control system includes a switch to detect whether the doors are in the upper or lower position. Sensors acting as limit switch are installed at both the top and bottom of the door. Furthermore, the door is equipped with a wind sensor to prevent opening in strong winds. DROMEC has also incorporated a built-in functionality to seamlessly switch from the regular power supply to a generator if necessary.

 

Pieter van Roekel from DROMEC:
“The Smulders project showcases a combination of precision and weight within a timeframe of approximately 15 weeks. We have made every effort to fully support Smulders throughout the process. The installation and tensioning of the cables were carried out by our experienced team in collaboration with our partners at TWS.”
