Ports, Jetties & Terminals
Ideal platforms for jetty construction support
Increase your workability
Using a jack up
Jack Ups or self-elevating platforms are ideal to support various scopes for ports, jetties and terminals construction and maintenance. Often these are capital intense and high profile projects, for example for the Defence Infrastructure Organization in the UK.
1. Stable Work Platform in Dynamic Waters
Combifloat jack-ups provide a secure, elevated base above tidal and wave action—ideal for precision tasks like piling, drilling, and concrete placement in marine infrastructure projects.
2. Modular and Rapidly Deployable
Their modular design allows for containerized transport and fast on-site assembly, enabling efficient mobilization even in remote or logistically constrained port environments.
3. Heavy-Duty Load Capacity
With deck strengths up to 20 mT/m² and high variable deck loads, Combifloat platforms can support cranes, piling rigs, and other heavy equipment essential for port and jetty construction.
4. Adaptable to Project Phases
Whether for initial geotechnical investigations, foundation works, or final outfitting, Combifloat jack-ups can be reconfigured and reused across multiple stages of a marine infrastructure project.
A variety of outriggers or piling and drilling templates can be installed on the platform to facilitate the (raked) piling or large diameter drilling work.
Combifloat has three jack up series currently in its portfolio:
Combifloat
C5
For smaller construction spreads and overwater 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 20mT/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.
Combifloat
C7
For heavy construction spreads
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 mT/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.
Combifloat
C9
Jack up for the heaviest loads
The largest in its kind; the C-9.5 Platform can take deck loads up to 1000 mT, offers a large deck area of more than 950 square meters with a deckstrength of 20t/m2.
With its standard-length spud legs of 58m deeper waters can be reached, up to 45m, subject to environmental conditions.
The platform has a Central Control System allowing the platform to be lifted and lowered synchronously and is delivered with IACS class notation.
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.
