WIDSON-50

A modular jack-up platform designed for coastal marine and inland waterway operations.

The platform was built in 2025, operates under the flag of the Russian Federation, and is registered at the Big Port of Saint Petersburg. Class: RMRS KE (★) R2-RSN self-elevating unit.

WIDSON-50 is designed for geotechnical surveys, dredging operations, and auxiliary technological works at coastal and inland waterway facilities. Its demountable modular design simplifies transportation and assembly and enables the platform to be adapted to the requirements of a specific project.

  • Purpose
  • Dimensions
  • Additional Specifications

WIDSON-50 is a modular jack-up platform designed for coastal marine and inland waterway operations. The platform is used at port and coastal infrastructure facilities where a reliable working platform is required, with the ability to elevate the hull on support legs and safely accommodate equipment.

The platform is suitable for geotechnical surveys using a URB 2A2 drilling rig or equivalent equipment, as well as for field soil investigations using static cone penetration testing. Operations may be performed both for port infrastructure, including berths and approach channels, and in offshore areas, including jack-up rig installation sites and landfall areas of offshore pipelines.

WIDSON-50 can also be used for dredging operations with an excavator weighing up to 25 tonnes, sediment removal using a mobile crane and submersible pump, placement of inert materials, drilling and blasting operations, and accommodation of a diving station and hyperbaric chamber for underwater engineering operations.

The platform has a demountable modular structure consisting of seven main modules and four modules for the jack-up support legs. The modules are connected using special reusable locking devices, making the platform convenient to transport, assemble, and adapt to different project requirements.

Our approach —
engineering for real-world challenges

We develop modular platforms for construction, engineering surveys, and heavy-duty hydraulic engineering works. Each configuration is selected according to the loads, water depths, and requirements of the specific project.
