Other activities


Supply of drinking water and onshore electricity.

MAIN is responsible for supplying drinking water and onshore electricity in the port of Den Helder. 

All quays have their own water supply points. The delivery capacity is between 40 m3 and 55 m3 per hour. Mains electricity is supplied mainly to fishing vessels and offshore stand-by vessels.

The Fishing for Litter project

Every week, a number of selected North Sea fishing vessels return to port with waste that has been fished out of the sea and collected in big bags. Commissioned by the North Sea Directorate of the Dutch Ministry of Transport, Public Works and Water Management, MAIN is responsible for collecting this waste and transporting it to a waste-processing plant. Since the project was started in 2000, more than 2,500 big bags of litter with a total weight of 600,000 kilos have been fished out of the sea and taken away for processing. 

Emergency services

MAIN has a wealth of experience when it comes to dealing with emergencies. The company has a wide 

range of equipment at its immediate disposal for dealing with oil spills. Our environmental protection 

vessels are regularly deployed for exercises at the request of the Ministry of Transport, Public Works 

and Water Management.

Onshore services

The terminal at Amsterdam has a jetty where seagoing vessels with a length up to 220 m and a draught 

of 11 m can be moored. The jetty offers ships the possibility of direct waste discharge, transhipment, repairs, cleaning work and cleaning of tanks.
