Shell to Sea campaigner Maura Harrington is on day nine of her hunger strike.
Shell Ireland says no decision has yet been made on whether repair work to the Solitaire will carried out in Ireland or at some other location in Europe.
Equipment on board the ship was accidentally damaged off the Mayo coast last week - an hour before it was due to begin laying the offshore section of the Corrib gas pipeline.
It returned to Killybegs, Co Donegal a short time later.
Ms Harrington says she will continue with her hunger strike until the ship leaves Irish territorial waters.
Shell Ireland said it would be making no comment on her hunger strike.
Earlier a group of politicians and filmmaker Ken Loach called on Shell to announce its intentions in relation to Solitaire.
Independent TD Tony Gregory, Senator David Norris, Joe Higgins and Patricia McKenna said every passing day increased the risk to her life and if Shell were to confirm that the ship was leaving, it might result in an ending of the hunger strike.
'The use of the Solitaire, which has left Broadhaven Bay for further repairs, by Shell Ireland, raises issues for the Irish government which so far they appear to be ignoring,' Labour Spokesperson for Foreign Affairs Michael D Higgins said.
Meanwhile The Pro Gas Mayo lobby group today deplored the painting of Shell to Sea slogans on the Garda station and Courthouse in Castlebar and on the office of a relative of a Shell employee in Castlebar.
'This is a further attack on the state property and institutions, particularly the Courthouse where justice is dispensed,' the group says in a statement.
It adds: 'We support the democratic institutions of the state in upholding the law of the land.'
