Heerema's Aegir installed DOT monopile at Eneco Amalia windpark
Heerema Marine Contractors has installed, together with its client Delft Offshore Turbine (DOT) and their subcontractor CAPE Holland, the DOT monopile at the Eneco Amalia windpark.
During the installation of the monopile a relatively new driving technology was used by CAPE Holland in combination with a new installation operation by Heerema's offshore lift vessel Aegir. The monopile was vibrated into the soil with a Vibro Lifting Tool which is a hybrid of a vibro hammer and lifting tool. Because of this no other tools were needed for picking up, upending and driving the pile to final penetration. By measuring the verticality during driving, the vessel and crane were able to control the verticality while operating in DP mode.
The installation by Heerema's Aegir was performed in floating mode on DP and with the monopile free hanging from the hook of the crane. No motion compensation frame from the vessel was used during the installation of the monopile. As a result of this operation the monopile is installed within the target box of 0.5m and has an inclination of 0.3 degrees with less required hardware.
Heerema Marine Contractors is proud to announce that the company has achieved a next and crucial step in its journey to progress the QUAD lift from an ambitious idea to an industry wide accepted technology. The QUAD Lift Development received its Technology Qualification Certificate from DNVGL.

Heerema Marine Contractors (HMC) has developed a globally unique, innovative way of lifting that will redefine the boundaries of lifting operations offshore. This ‘QUAD lifting’ was tested successfully on October 22, 2018 in the Gulf of Mexico. The QUAD lifting enables HMC to integrally install and/or remove oversized topsides or jackets. This revolutionary innovation is an important expansion of HMC's services and guarantees unmatched lower overall project costs.

Heerema Marine Contractors is incredibly proud to announce that our Installation Engineer Marius Ottolini has been elected winner of the 2018 “Offshore Energy Young Engineer Award.” Marius received his award for being one of the big drivers within Heerema in the development of silent foundations, with the aim to reduce or eliminate piling noise. Such noise can affect the marine environment to a substantial degree. He has developed several alternatives which are a step change in foundation design, in particular because the foundation can be installed silently and it can be completely removed after it has reached its end of life.
