Modular C-7 Cable-Lay Barge
for Inland Subsea Cable Installation
Combifloat enabled heavy subsea cable installation in a remote inland location
where a conventional cable-lay vessel could not be used.
Remote Inland
Cable-Lay Challenge
In a remote inland water location in Scandinavia, Combifloat supported a specialist marine cable installation contractor with the installation of high-voltage subsea power cables across water depths exceeding 200 metres. The landlocked project site was accessible only by road, which made the use of a conventional cable-lay vessel impractical.
The Challenge:
The project required the installation of heavy subsea cables, with a cable reel weighing approximately 150 tonnes, in a confined inland water environment. Deep water, steep shorelines, limited site access and logistical restrictions all placed high demands on the installation method and project execution.
Controlled Positioning
The modular barge was operated with controlled movement along the planned cable route, supporting accurate cable placement in deep water.
Road-transportable deployment
The modular components were transported by road and assembled on site, enabling heavy cable installation in a remote inland location.
High deck load capacity
The C-7 provides a compact but stable working platform for the equipment while handling significant (point) loads. Combifloat’s pontoons have the highest deckload amongst its peers. (20 t/m2)

The
Project Outcome
The cable installation was completed safely, efficiently and on schedule, demonstrating the value of Combifloat’s modular platform systems in challenging inland water environments. By avoiding the need for a dedicated cable-lay vessel, the solution provided a cost-effective and adaptable work platform while still meeting the positioning and load-handling requirements of the cable installation. The project shows how Combifloat systems can be rapidly configured for complex marine operations in locations where conventional vessels are not a practical option.
Proven
Performance & Compliance
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.
