The Barke® High-Lift flap rudder is the solution for any vessel with high manoeuvring requirements combined with significant fuel savings.

With its progressively rotating flap, this rudder type generates high lift forces at large rudder angles and low drag (resistance) at small rudder angles.

The enclosed linkage system of the Barke® rudder provides overload protection and eliminates the entry risk of sand, ice and floating objects. These are ideal characteristics for fishing and research vessels, and dredgers.

With its in-house cylinder design, the Commander™ Piston-type guarantees reliability and high quality. This steering solution offers multiple options in rudder stock connections, rudder angles and cylinders, which makes the installation process efficient and space-saving.

Piston-type steering gear is available in standardised series with different configurations but can also be custom-built according to specific requirements. The torque range varies from 1 up to 425 kNm with rudder angles up to 65 degrees.

A tugger winch is made to perform frequent assistance work on any type of vessel. Tugger winches can be used for multifunctional work on tugboats and other work boats and are used for a wide range of tasks. A DMC tugger winch excels in its simplicity. Despite their simple, robust design and heavy-duty construction, DMC tugger winches function as reliable winches. The performance of our tugger winches is assured because we select only the highest quality gearboxes. DMC tugger winches set themselves apart by their low-maintenance design and long service life.

Available models

Type of cable: Synthetic wires and steel cable
Pulling force: 3, 5, 10, 15 tonnes (higher forces are available on request)
Drum configuration: Single, smooth or grooved
Drive: Hydraulic or electric

Advantages

• Robust design with durable materials. The design of our tugger winches is simple but effective as well as low in maintenance. We are able to achieve this by limiting the number of parts, making critical parts robust, using stainless steel and opting for high-quality rotating parts. In addition, we minimise the number of rotating points, levers and lubrication points.
• Quiet, compact transmission. Tugger winches from DMC are equipped with high-quality gearboxes.
• Superior anti-rust protection. Our tugger winches are fully coated with a high-quality, 3-layer paint system. The base layer is an extremely zinc-rich primer which has a zinc content of more than 90%. This ensures that our robust winches are optimally protected against corrosion, even under the most extreme conditions.
• Easy alignment and attachment. All DMC tugger winches are designed to be deck-mounted with only four foundation points. This standardised print ensures easy alignment and attachment of a DMC tugger winch to the deck. It also results in as few obstacles as possible on deck, where towing wires can become snagged.

An anchor and mooring winch is applied to cargo and container ships so that they can moor safely at the quay and remain moored at their berth. These winches ensure the safety of the crew and the cargo of a ship. Inland tankers are also often equipped with this type of winch. DMC anchor and mooring winches comply with all Bureau Veritas class requirements. Depending on the wishes of the customer, it is possible to obtain certification in accordance with ATEX or OCIMF guidelines. Our range of anchor and mooring winches is designed for intensive use. For example, when waiting offshore in stormy weather for the next tow. Where regular anchor winches can only handle short-term peak loads, DMC anchor and mooring winches have the ability to actually pull and hold the forces at the nominal motor torque. Multiple configurations are possible as we build our winches with standardised modular solutions. In addition, customisation is always an option.

Asymmetric Rudder Technology (ART™) is a unique leading edge that is adapted to the angles of the propeller to create smooth water inflow. This technology is developed to reduce resistance and cavitation. The profile of this Energy Saving Device is specifically modified to counter the rotation effects of the propeller slipstream. It is an optional feature that can be applied to all Van der Velden® rudders.

ART™ is available in two versions: the S- or Z-shape. The S-shape has a more detailed design, it therefore reduces the risk of cavitation even more than the Z-shape. Nevertheless, the cavitation risk is significantly reduced with both versions, in comparison to a conventional leading edge. Increased operational profile and extended product lifetime are the results when ART™ is applied to a rudder.

The Timon rudder is known for its excellent manoeuvring and course-keeping performance. This rudder has an open flap linkage mechanism and side bar flap system with a 90 degree angle. It has a wide range in size, which makes it the ideal rudder for larger vessels such offshore and container vessels.

Optional Energy Saving Devices

• Asymmetric Rudder Technology (ART™)
• Rudder bulb

Other optional features

• Heel bearing support. This feature improves the performance of the rudder and is often applied to fishing vessels. It reduces the load in the neck bearing and it protects the propeller from fishing nets. With heel bearing support, a rudder can be designed with a slim profile. The distribution of rudder reaction forces in three points (rudder carrier, neck bearing and heel bearing), compared with the free hanging rudder, will increase the strength of the rudder, especially during trawler operations.
• Rudder trunk extension. To extend the trunk into the rudder blade, the lower neck bearing is positioned as close as possible to the centre of the force that is acting on the rudder. This gives the opportunity to build large rudders. With trunk extension the stresses, from bending, in the rudder trunk and stock are reduced. Also, the reaction forces in the neck and carrier bearing are smaller.

Towing winches are often used on tugboats assisting container ships and other cargo ships in ports and port terminals. The pulling and braking force, in combination with the transmission, determine the application of this type of winch. DMC’s towing winches, driven by gearboxes, are unique in use. This solution developed in-house ensures that the speed of the winch is automatically adjusted to the required pulling force. The variable speed allows the winch to always run at the highest possible speed. This eliminates the need to manually choose between two or three-speed models.
