Aircraft and Ships

The external skin of an aircraft is of extreme importance.  An aircraft can also be placed ‘in mothballs’ in its entirety, including the motors, the electronic equipment and all other systems!

This is not the case with ships. Here we ensure that the interior of the ship is hermetically sealed – the machine room, accommodation, deck houses, as well as the funnels and ventilation shafts. In addition the deck installations are separately enclosed. The Cocoon Mothballing System is adapted so that the interior of the ship can be reached at any time without compromising the conservation system.

In Den Helder 1960, the first mine sweepers were conserved using the Cocoon Mothballing System.  In 1976, these ships were re-commissioned and were put back into service, following a normal check of the apparatus, as carried out when a ship has been out of commission for three months.

During the 16 year period of storage, no maintenance was carried out on the ‘mothballed’ parts of the ships, including nautical and weapons installations on the deck.  This method was so successful that since then, minesweepers have regularly been ‘mothballed’.
