Workboat 93
The WB 93 is a compact transportable workboat that can be successfully deployed in several different projects and activities such as dredge support, fish farming, Off shore support, diving support. This workboat can be delivered in several configurations. There is a basiic version with an "open" cabin and an option to have a tiltable hydraulic propulsion form working in shallow area's with debris in the water.
Suitable waters and enviroments
The WB 93 is engineered to perform reliably in a wide variety of aquatic environments, making it an exceptional choice for operations that demand flexibility, mobility, and durability. Whether operating in calm inland waters or more demanding coastal zones, this workboat offers stable performance and easy maneuverability even under challenging conditions.
Its shallow draft of only 0.7 meters allows the WB 93 to access areas that are typically off-limits to larger or deeper-draft vessels. This makes it ideal for shallow rivers, tidal flats, estuaries, and confined port spaces where precision and compact dimensions are essential. Combined with its powerful propulsion system and optional tiltable hydraulic drive, the WB 93 maintains full control and propulsion in waters that contain debris, mud, or loose sediment.
In addition, the vessels is well-suited for dynamic environments where water levels and current conditions may change rapidly. Whether it's working alongside dredging operations, fish farms, or offshore platforms, the WB 93 is build to adapt.
Compatible ground conditions
The WB 93 is not only designed to handle various water environments it’s also built to operate efficiently over a wide range of underwater ground conditions. This versatility makes it an excellent choice for work in both natural and man-made settings where sediment types and bottom structures can vary significantly.
Thanks to its robust construction, powerful propulsion, and durable deck equipment, the WB 93 can be used effectively in areas with:
- Sandy seabeds, commmon in coastal zones and dredging areas where stability and traction are essential.
- Muddy or silty bottoms, typically found in estuaries, harbors, and riverbeds, where fine sediments require steady maneuverability and equipment capable of resisting clogging and wear.
- Rocky or mixed terrain, such as those encountered near breakwaters, jetties, and infrastructure projects, where strong anchoring and durable hull protection are crucial.
The combination of a 20 kN anchor handling winch, a 2.3 mt hydraulic knuckle boom crane, and optional towing gear enables the WB 93 to operate safely and efficiently regardless of the substrate. These features also ensure that heavy equipment and anchor points can be deployed or retrieved without compromising vessel stability or safety.
Whether performing maintenance, transporting materials, or supporting marine construction, the WB 93 adapts seamlessly to the challenges presented by different types of seafloor and shoreline terrain. This makes it a dependable platform for professionals who work in varying underwater landscapes and need a vessel they can count on under all conditions.
Project applications
The WB 93 stands out as a highly adaptable and multifunctional workboat, capable of supporting a wide range of maritime and coastal projects. Its compact design, powerful equipment, and multiple configuration options make it an indispensable asset across industries that require reliability, flexibility, and ease of deployment. From daily operational tasks to specialized missions, the WB 93 is designed to deliver results in both routine and demanding environments. Its size and maneuverability allow for fast mobilization and access to remote or restricted areas, while its onboard systems and equipment ensure it’s ready to perform a variety of roles on the water.
- Dredging support, ideal for anchor handling, crew transfer, and support near dredging sites or pipelines.
- Fish farming & Aquaculture, supports daily operations like feeding, net inspection, and equipment transport.
- Offshore & Nearshore Maintenance, assists with light maintenance, personnel transfer, and equipment delivery to offshore structures.
With multiple configurations and a customizable layout, the WB 93 is a versatile solution for a wide range of maritime projects. Feel free to contact us for more information.
