Harbour and breakwater construction has been an important activity for PETER MADSEN REDERI A/S since the company’s conception in 1954. Today stone works are one of the key areas of works, with varied projects such as:
Breakwaters.
Erosion and scour protection in ferry berths.
Erosion protection around bridge piers and other marine foundations.
Planed stone beds to lighthouses, offshore windmills and bridge piers.
“Stonefishing” was for many years the main occupation of PETER MADSEN REDERI A/S. Today we mainly work with different stone suppliers and no matter how the stones are delivered we have the appropriate equipment to quickly, efficiently an accurately place stone into their final position.
In recent years the company has been greatly involved in some of the very large marine civils projects that have taken place in Danish waters, and as a result our present work-force has become highly proficient in all types of erosion protection and planed stone bed construction. Another result of these large projects is that the company has evolved production and control systems to ensure the effective laying of large amounts of stone to tight programmes and tolerances.
We can digitalise stone profiles of breakwaters and stone beds so that with the help of dredging monitoring systems and DGPS positioning, the crane/excavator operator can see where every single bucket load of stone should be positioned, ensuring accurately placed stone layers are constructed within specification.
PETER MADSEN REDERI A/S has ensured that it has stayed at the forefront of inno-vation. By investing in 3 specialised hydraulic planing machines that with the help of a differential pressure sensor system we can place planed stone bed for foundations to ex-tremely high accuracy and reliability. Video equipment positioned on the planing ma-chines ensure that diving assistance is kept to a minimum, and optimises production and control levels.
Our versatile fleet of vessels and equipment, alongside state-of-the-art technology en-sures that every project can be set up in the most effective manner, whatever the clients needs are. |
