At the royal Navy in Den Helder afd. SEWACO
a problem had arisen regarding Arma Brown gyrokompassen, a/b of several surface ship.

CTW MARINE-SYSTEMS had the correct approach of the problem and had a good flexibility and sufficient experience with the gyrokompas, to carry out the budget and "just to the task within in time". The maintenance dereparatie/acquired characteristic was spent from that on CTW MARINE-SYSTEMS. It concerned the gyrocompassen for Hr. m AMSTERDAM (A836), Hr. m ZUIDERKRUIS (A832) and Hr. m ROTTERDAM (L800).
