Operating out of one of the largest and busiest ports in the world, Stemat bv has been leading the way in maritime services for over a quarter of a century. We find out what makes the company tick, courtesy of Commercial and Operational Manager, Robbert Jan van Zuiden.
PES: Welcome to PES magazine. Would you like to take this opportunity to explain a little about the company and how you serve the wind industry?
Robbert Jan van Zuiden: Stemat is a service chartering company for the maritime sector, based in Rotterdam, The Netherlands. Stemat was founded in 1986 utilising two vessels and expanded to a current fleet of more than 50 vessels in 2014. The considerable experience gained in this time allows Stemat to offer expert advice to a large number of companies specialising in a wide field ranging from maritime construction to the dredging, offshore industry and the renewables sector.
In 2009 we launched the DP2 cable lay vessel “Stemat Spirit”. With her six point mooring system and plough system and large free deck space she is very successful in laying and burial of export cables. After her last modification, installation of a twin deck, she is suitable for laying infield cables as well. Stemat Spirit recently completed her first infield lay project successfully.
In 2013 we extended our fleet with a 24 pax high speed crew tender Liz V, currently working in offshore wind farms to transport technicians from shore to the turbines or vessels at 30 knots. In 2014 we launched the first DP2 Multi-purpose vessel in Europe, Anna B. With her Dynamic Positioning system Anna B is besides towing and anchor handling also employable for preparatory work (Pre Laying Grapnel Runs) in the construction phase of new and existing offshore wind farms.
Anna B was launched together with a 50ton bollard pull anchor handling tug Inge W which is suitable for towage, anchor handling and general assistance for our Multi-Purpose (Accommodation) barges Stemat 82, Stemat 89, Pontra Maris and Fetsy L. With their voluminous free deck space these barges are more than suitable for cable laying, cable jointing and cable reparations. We equipped our flattop barges Stemat 87, Stemat 91 and Stemat 92 with carrousels for storage and transport of cables.
