Modular platforms for geotechnical operations

Jack-up platforms are widely used in geotechnical works due to their unique ability to provide a stable, elevated, and mobile base in marine and nearshore environments.
The C-5 and C-7 Series Self Elevating Platforms predominantly operate in the geotechnical arena in coastal and inland waters.
Here’s why they’re so instrumental:
- Unmatched Stability for Precision Work
Jack-ups elevate above the water on steel legs, creating a vibration-free and wave-independent platform. This is essential for geotechnical tasks like borehole drilling, cone penetration testing (CPT), and sampling, where accuracy and consistency are critical. - Access to Challenging Locations
They can be deployed in shallow waters, intertidal zones, and soft seabeds—areas where floating platforms or land-based rigs would struggle. This makes them ideal for early-stage site investigations for bridges, tunnels, ports, and offshore structures. - Modular and Scalable
Modular jack-ups like those from Combifloat can be configured to suit project-specific needs, transported easily, and assembled quickly on-site—reducing mobilization time and cost. - Safe and Efficient Operations
With a clear and dry working deck, jack-ups offer a safer environment for crews and equipment, especially compared to barges or floating rigs affected by tides and swell. - Drilling slots or moonpools
Drilling slots or moonpools to facilitate the drilling works can easily be created by shifting pontoons during the assembly of the platform or integration of a drilling slot in one or more pontoons.

C5
For smaller construction spreads and marine site investigations
The modular C-5 Self-Elevating Platform is the ideal jack-up platform for construction and geotechnical works in coastal and inland waters. The design provides a platform for lighter and smaller spreads of equipment.
With a 100 ton variable deck load capacity and 20 t/m2 deck strength, the C-5 is the platform of choice for geotechnical companies. Over 250 m2 deck space is usable without obstructions. The deck layout can be fully tailored to client’s mission equipment and operating method.
To facilitate drilling operations, moonpools or drill slots can be created. This can easily be done by shifting pontoons during assembly or by integrating a drilling slot in a pontoon.
Depending on soil penetration and waves, the platform can cover water depths up to 23 meter, with extensions possible in a moderate environment.

C7
For heavier spreads or deeper water
The modular C-7 Self-Elevating Platform is the ideal jack-up platform for port and nearshore marine works. The design provides maximum uptime for construction and maintenance of terminals, jetties, ports, breakwaters, bridges, land- and outfalls of cables or pipelines and offshore facilities.
Offering a 400 ton variable deck load capacity and an unparalleled 20 t/m2 deck strength, makes the C-7 the platform of choice for heavy duty marine construction works. It provides a large 520 m2 free deck space. Without obstructions on deck, the deck layout can be fully tailored to client’s mission equipment and operating method. Depending on soil penetration and waves, the platform can cover water depths up to 30 meter, with increases possible in moderate environment.
Safe and efficient lifting, lowering and (re)positioning of the platform is enabled through the central or local controlled jacking system and 4-point mooring system. Redundancy is provided by two independent hydraulic pump sets and manual control of crucial platform functions.
Proven
In the field
The Combifloat pontoons offer full customization and can be equipped with many attachments and accessories specifically needed to successfully execute projects. The C-5 series are often used for geotechnical services and inland marine construction works and offer a 15 T/m2 deck strength just like the C-7 and C-9.5 series. All C-5 series components are fully IACS compliant and delivered with individual test certificates.
