CAPEX savings

Reducing cost by reducing weight

For highly loaded connections the C1 Wedge Connectiontm can be lighter than the traditional L-flange reducing the cost for steel and CO2 emissions. Further savings can be obtained by reduced costs for secondary steel such as the use of a slender airtight platform ring and the high speed of installation.

Reducing the cost for high capacity connections

High Capacity Connection

At a reduced diameter

The design of the C1 Wedge Connection™ allows for significant savings on primary and on secondary steel. With monopiles going to deeper water, the wave loading on foundations becomes more of a design driver requiring additional steel at mudline-level. The C1 Wedge Connection™ allows for smaller diameter interfaces and thereby a significant reduction of these wave loads. This reduces the monopile weight.

A typical example of a saving on primary steel is the air-tight platform ring that is typically placed in monopiles. These air-tight platform rings allow for a platform to be placed inside the monopile sealing it off from the corrosive air below the platform. Typically, these platforms rests on large rings that protrude inwards further than the L-flange above allowing the platforms to be lowered through the L-flange onto these rings. These welded rings need to survive pile driving, as a result their construction is very expensive. 

The slender design of the C1 Wedge Connection™ does not have any significant inward protruding rings allowing large savings on such details and reducing the risk of damages during installation.

More benefits

Simple to design

The design is typically governed by the overturning moment and the diameter of the connection.

Easy Installation

The C1 Wedge Connection™ is designed for a personnel free connection and fast installation.

Maintenance free

The C1 Wedge Connection™ is designed to be maintenance free due reduced sensitivity to preload loss.
