My main competence lies in connecting people and business and maintenance of relationships and contacts. I can negotiate business with a sensitive feeling for (commercial) relationships in conjunction with a proper assessment of risk levels. I attach great importance to the fulfillment of agreements made.
I am able to bring team spirit where it seems seemingly impossible and willing to think and go off the beaten path, but not without first measuring and creating sufficient support. This “out of the box” thinking also applies to the inventing of new working methods and techniques, and the development of solutions in managing an organization and execution of projects.

Work experience (2001 - present)

2014 – present – Various consulting assignments

Over the past few years I have been able to carry out various assignments in the field of advising companies in the dredging industry
For example, the companies Severn Sands Newport (UK) and Trade and Minerals Nowak, Gdansk (PL) are part of the list of companies I have been able to advise in improving operational processes and organization.

2013 – Interim manager DC Dredging BV

DC Dredging BV consists of a number of (7) companies under the umbrella of Group de Cloedt NV (BE) and are compiled as a production company to win and sell marine aggregates to mainly internal but also external customers. In addition, dredging projects are also carried out. This is done by a fleet of 5 seagoing Trailer Suction Hopper Dredgers and 8 inland shipping vessels. Every company had its own culture and it was my challenge to build an organization (about 80fte) in which anyone can identify him/herself with the new born company. The fact that this was successful is reflecting in rising revenue, profit and performance figures over the last 3 years together with a high level of involvement and little progress among staff. The turnover lies now around 30mln euro. The next step has been taken with expansion of the fleet. This made it necessary to adjust the organization to meet the growth ambition. Adaptations have been made in the following areas: ICT, HR, ISM, administration and technical services.
