Most of the companies are small and/or midsized firms that operate on a national level. Only a dozen or so large hydraulic engineering companies are active on a truly European or global scale. The Netherlands is particularly strong in this sector.
The many vessel types used in hydraulic engineering include trailing-suction hopper dredgers, cutter-suction dredgers, backhoes, floating grab cranes, pontoons and floating sheerlegs. Onboard, the personnel most likely to be Nautilus members are shipmasters, chief engineers and other deck and engineering officers. Sometimes a vessel’s ratings are also members if Nautilus has a ‘single union’ agreement with the company.
Collective bargaining agreements
Nautilus has collective bargaining (recognition) agreements (CBAs) with several companies in this sector, and in the Netherlands Nautilus has a CBA (CAO Waterbouw) which covers the entire Dutch sector. For company-specific bulletins and other documents for members, please log in to the Members area. There is more about how collective bargaining works on the We organise and We negotiate pages.
