Adonai’s long-standing knowledge of the market is the basis for its ideology, which is to provide highly trained personnel and deliver outstanding customer service at all times. Our organization is dedicated to serving its clients and crew as best it can to ensure satisfaction of customers and staff alike.

Our ideology is based on experience of many years within the branch. For many years we have been sending crew across the world. We have regular contacts within the Dutch & International Shipping Trade and we make new contacts regularly. To us it is very important to serve our clients and our crew on board as best as we can; we want to make sure that all parties are satisfied.

Our success depends on the abilities and commitment of all employees. We value loyalty, honesty and integrity and we treat each other with mutual respect. We share information and promote teamwork throughout the organization and with our clients, business partners and associates. We seek to be an employer of preference and encourage training and personal development.

Because working on board is not only about technical skills, we always prepare our crew for the social part of the trade. Cooperation and mutual understanding are important issues on board. Furthermore, we think it is very important to treat our seafarers with respect. They can come to us for social problems as well. We do not only want to be an employer to them, but also a home.


We provide our services to international shipping companies operating worldwide. We are active at the North Sea, West Africa and Middle East.

We do work closely together with the shipping companies to whom we supply crew, as we believe you do the job together and a close relationship enables us to provide our services to the best. It also enables to create a high safety awareness among the crew.

We have excellent levels of communication between our employees and clients, and as a result, we have a respectful and open culture at Adonai.
