It was built in 1977 by the Swedish navy and was known then as the MS Trymbergen.
Greenpeace chartered the ship in 2000. Previously it was used for fishing excursions and navy training at sea in Norway. The vessel was converted and renamed the Argus. Its port of registry is the Leuvehaven, Rotterdam.
In Greek mythology Argus is a giant man with eyes all over his body so he can watch everything very closely. This is symbolic of the Greenpeace Argus ship, which closely monitors pollution.
The first action of the Argus was in September 2000. A giant stamp saying "Stop TBT" was attached to the ship's crane and then used to brand ships painted with TBT paint.
In February 2001 when a ship, the Saga Tide, carrying timber cut from Canadian ancient forests wanted to enter the Netherlands harbour of Flushing; the Argus was there to prevent it.
During May 2001 Greenpeace used the Argus to help block the heavily contaminated Rotterdam chemical harbour. Greenpeace demanded that producers AKZO, Shell and Shin Etsu cleaned the chemical harbour.
Journalists could sail to the North Sea on board of the Argus at the end of July 2001. There Greenpeace placed the first offshore windmill in the sea. Exactly at the location where Clyde Petroleum had planned to drill for gas.
The mud in the harbours of Rotterdam, Breskens, Terneuzen and Flushing has been seriously contaminated with TBT. In October the Argus dredged up some of this toxic mud. Part of it was dumped at Atofina in Flushing.
He writes:
As we sailed into the harbour we received a radio message saying that we were not allowed to enter.
However, our captain, Hans, stoically answered: 'Yes, so I understand.' But entered the harbour anyway.
We dredged up the toxic mud onto the ship. When a police-boat finally arrived, we had almost finished our job. One hour later we took off.
Later that day I spoke with the harbourmaster. I told him why we were dredging there. First he threatened to undertake action against Greenpeace. But he also admitted the action had some advantages.
Normally the harbours have to pay for the costs of dredging. And now Greenpeace was dredging up the contaminated mud.
The actions against the chemical TBT were successful. On 5 October the UN International Maritime Organisation decided on a worldwide ban of TBT in ship paints.
