The Maasdam just had a dry-dock, and one of the things on the list was refurbishment of the teak decks. The only remaining space was the bow, namely Deck 7 forward. This one can never be done during the dry-dock period, as this deck is always filled with containers and garbage skips. The superintendent therefore scheduled this to be done on the run.
As Maasdam is an older ship, her teak decks are still laid in the traditional way. The more modern way was shown before on the Eurodam News Blog. The traditional way of fitting teak decks on steel ships was by welding rows of bolts on the decks. The planks, being about 1 1/4″ thick, had holes at corresponding intervals and were connected to these bolts with nuts. A teak plug seals the hole. All that remains is the caulking.
In the photos you see the caulking in progress. First, the old caulking is removed from the grooves using circular saws along guide rails. For those hard-to-reach spots, they use routers. After that, and a preliminary sanding of the deck, plastic tape is laid in the bottom of the groove. This to ensure the caulking only adheres to the sides and not the bottom of the groove. Then the caulking is applied. After a 48-hour setting period, the whole deck is sanded down smooth, removing at the same time the excess caulking and the deck is good again for another five years.
Good way to spend a sunny Sunday afternoon in St. John’s, Antigua!
The little triangle on the starboard side is only part left to do, which is a good thing — they have only four days left and quite some finishing touches to do!
