Winches for Van de Gruiter

On behalf of Van de Gruiter we developed a unique set of winches. For the outfitting in the Netherlands a yacht needs to be transported behind a tugboat through a number of sluices. During locking, the tugboat and the yacht cannot fit into the lock simultaneously. For this purpose, DROMEC Winches developed a quadruple winch system on the hull of the yacht.

Quadruple winch system

Using 4 electric mooring winches with a pulling force of 5500 kg on deck 1, the hull is secured before entering the lock. The tugboat passes through the lock. Subsequently, the 70-meter cables with a diameter of 28mm are attached to the bollards in the lock. The 4 winches with controls pull the hull into the lock. After locking, the cables are disconnected and reattached to the tugboat. Similarly, the hull is then pulled back to the tugboat.

Free-wheeling clutch

The 4 winches are identical, they are mirrored at the bow and on either side of the aft deck. The cable is retracted at a speed of 10 meters per minute. The winches are equipped with a manually operated free-wheeling clutch, a crucial requirement for these winches. With a drum in free-wheel mode, the operators on shore can pull the cable to the bollard. And once the cable needs to be released, the drum goes into free-wheel mode. When the cables need to be retracted again, the drum is reconnected to the drive for rewinding.

Controls

DROMEC Winches has mounted a frequency-controlled control system on the winches. With a user-friendly handheld controller, the operator can incrementally increase and decrease the speed with push buttons.

Joost Ressing:
‘We have connected a control system to each winch, making it a complete set that is versatile. This way, multiple yachts can be moved over long distances. The collaboration with Van de Gruiter was pleasant, and communication was good on both sides. Despite the tight delivery time, everything worked out well!’

DROMEC Winches Supplies Winch System for FLEET CLEANER Delft

FLEET CLEANER Delft specializes in cleaning seafaring vessels in ports such as Rotterdam, focusing on efficiency during the loading and unloading processes. DROMEC Winches has supplied a winch system for the work vessel Thunderbird 4 of FLEET CLEANER, enabling environmentally friendly cleaning of ship hulls.

 

Umbilical System

Onboard FLEET CLEANER’s work vessel, a crane with a remote-operated robot, known as the ROV (Remote Operated Vehicle), is positioned. This robot is controlled remotely and connected via an umbilical cable to the system provided by DROMEC. Within this umbilical bundle, hydraulic, electrical, and data cables are integrated, along with a wastewater hose, allowing for eco-friendly water discharge. The winch is suitable for ATEX environments, enabling FLEET CLEANER to clean oil and chemical tankers as well.

 

Mechanical Coupling

DROMEC Winches’ winch system can spool up to 180 meters of umbilical cable. The fully electrically powered system boasts a pulling capacity of 2.5 tons and a holding force of 4.5 tons. The cable can be reeled in at a speed of 30 meters per minute. DROMEC Winches has specially developed a mechanical coupling on the cable guide, which is detachable, allowing FLEET CLEANER to manually adjust the cable. This feature proves particularly useful for the umbilical cable, which may not always maintain a consistent shape.

 

ATEX Certification

Jan Willem, engineer, explains,
“While this winch system has the size of a container, it is very straightforward to operate with just two buttons on the control panel for speed and winding. All components are ATEX-certified, except for the control unit located below deck. An interesting development is that DROMEC Winches now also develops winches with full ATEX certification, including control units. DROMEC has already developed a wide range of umbilical winch systems, providing us with a diverse selection of models.”

Custom EWA-650-KB anchorwinch

This week we again supplied an EWA-650-KBV wire anchorwinch. Due to the onboard situation, the requirement was to position the winch directly near the living area, to realise extra free deck space.

Because of this a modification to the bandbrake handle was needed. Now the handle points horizontally forward instead of the standard vertical position.
Also a 35 x 7 non rotating cable is spooled on the drum with right pre-tension. This cable is equipped with an open spelter socket to make anchor assembly quite easy.

Are you looking for a standard anchor winch or are you looking for a special execution? Dromec provides a solution!

Hydraulic tugger winches for Herman SR. BV

Recently Dromec supplied two hydraulic tugger winches of type HPV-12000 to company Herman SR. BV.

Herman SR. BV supplies workboats including crew for all kind of maritime projects. Both  HPV-12000 (12 mT on layer 1) as the 15 mT variant, HPV-15000 are available from stock.

The winches are characterized by a solid and compact design and cable capacity of 104 mtr. In 5 layers. Winches are equipped with a disc braken and brake valve and plug and play to use.

As surface treatment, a 3-layer offshore coating RAL9005  is applied. Nice to see that also Dromec’s  cable spooling machine type DPW-750 is in use!

Dromec wishes Herman SR. BV many safe and pleasant jobs.

Compact, safe and powerful winches

In recent years, we supplied several winches to our customer Waternet Amsterdam. De winches on the photo’s where supplied in 2019 and are used as couple & mooring winches.

In that time, the customer required powerfull and safe winches with minimal impact on shipdesign and free deckspace.

Because outgoing cables run below deck and are completely covered, a safe working environment is created.

Recently we replaced new stainless steel drum covers.
