Project 300MU Global Tech I

The Patented 300MU is initially developed for Hochtief as contractor in the Global Tech 1 wind park. This 400MW project counts 80 turbines in the German EEZ-zone in the North Sea. This project started in August 2012 and upon completion in 2013 it will deliver electricity for an equivalent of 445.000 households.
The turbines will be build on tripod foundations. Three piles anchor a tripod foundation so the 300MU will drive 240 piles. The 300MU is on deck of the Innovation vessel and powered by the giant hydraulic power unit PVE 3200. This power unit is equipped with 4 Volvo engines, over 3000 HP and delivers 3200 l/min oil flow.

Dieseko and Offshore: vibrating technology in this highly competitive market


Project 400M (200M twin) German North Sea

Intended for foundation piles for a tripod based wind turbine. A tandem set was developed and supplied to pre-drive the piles, before using impact hammer.
Benefits PVE400M: insurance on inclination and time savings


Project 200M Hooksiel, Germany

A PVE 200M pre-installed three foundation piles for Hooksiel demonstration project for a tripod foundation of a BARD 5MW turbine. The piles were driven in shallow water conditions and our PVE200M also upended the piles.

Project 400M (200M twin) in China

PVE congratulates NTOC for pioneering the vibratory driving method for the installation of wind turbine foundations in China. Since 2010 NTOC has built the foundations of 48 wind turbines in Jiangsu Province’s Rudong Tidal Zone firmly establishing itself as a major player in the offshore wind turbine installation field. 

NTOC purchased two 200M vibratory hammers in 2010 and has used these to drive over 250 piles.
The 200M's are operated from the Hayang No. 36 vessel which has a 350t lifting crane and a D250 diesel hammer. The majority of the turbines had five pile foundations; NTOC also installed a number of six pile jacket foundations. The diameter of the piles varied from 1.4-1.8m and had a length ranging from 45-60 meters. The vibratory hammer drove the first 10-20m of the pile allowing for accurate positioning and controlled driving avoiding excessive hammering noise eliminating the risk of running piles and reducing the stresses on the pile that may cause pile fatigue by the D250 Diesel hammer that was used to drive the piles to final depth.
