Welcome to AMP

Allseas Maritime Personnel (AMP) is actively involved in the recruitment of maritime personnel for vessels operating for the merchant navy and on supporting offshore vessels for the oil and gas industry. The manning agency is located in the port of Den Helder, in the northern part of The Netherlands.

Manning of the vessels is done in accordance with STCW and MLC 2006 regulations. Competent and highly motivated crews with a sound safety awareness are the assets of our organisation. For a vast number of Dutch and foreign shipping companies AMP provides part or complete crew management. For shipping companies it means an enormous reduction in their daily operational crewing activities.

In May 2012 AMP received from Lloyd's Register the certificate of approval for ISO 9001:2008 for crew manning services in accordance with the MLC 2006 regulations.

Company profile

AMP was originally founded in 1985 from a Swiss based Geneva office and an operating office in Den Helder to start employing foreign seafarers, mainly for various Dutch ship owners. In the year 2000 the activities were taken over by Ravanta Holland BV and centralized in their newly built office in Den Helder-Holland. Since then the company continued the recruitment services under the trading name Allseas Maritime Personnel (AMP) and expanded their services for a vast number of Dutch and foreign ship owners. In 2005 the company introduced a new Personnel Data System, specifically designed to recruit and administer seafarers, including wages administration, visa application, crew's insurances and Owner's related employment specifications. Our working philosophy is based on respect for and trust in all human beings. In October 2013 AMP was taken over by Hylke Zetzema and Jan Zetzema. Under the new ownership AMP strives to continue the well known service to our clients and seafarers.
