PORTS, JETTIES & TERMINALS
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, like recently in the UK for the Defence Infrastructure Organization.
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:
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 15 ton/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 medium 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 15 ton/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.
C9 – jack up for heavy construction
The C-9.5 Platform can take deck loads up to 1000 mT, offers a large deck area of more than 950 square meters and with her spud legs of 58m can work in water depths 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.
