Tauranga boaties are being reminded to pay close attention and steer clear of the barge working on the Rena, currently sitting in Tauranga Harbour.

There have so far been no breaches of the exclusion zone around the Resolve RMG 1000 barge, which is the size of a football field, temporarily anchored at the south of Sulphur Point wharf.

It moored in port after transporting the first section of the Rena's accommodation block from the Astrolabe Reef on March 13.

The barge, one of the largest to visit Tauranga, remains anchored one cable due south of Sulphur Point wharf, between the wharf and Sanfords, with a number of hefty anchors and wires.

Harbourmaster Jennifer Roberts says the large barge is moored with multiple anchors and wires, with two additional wire ropes to the shore.

'Each anchor is marked with a large orange buoy, lit at night with a blue strobe. The wires are marked with floating line that has orange floats and blue strobe lights fitted at 20m intervals, so it is very visible,” says Jennifer.

And so far boaties have been very good at keeping clear of the anchors and wires surrounding the barge with no reports from Resolve of any problems, says Jennifer.

The sheer size of the barge and its anchor wire means it can be hazardous for other boats, and boaties are urged to keep well away.

The 300 tonne section of the accommodation was last month cut from the sunken aft section of the 236 metre ship that grounded on Astrolabe Reef on October 5, 2011.

Jennifer reminds boaties the two nautical mile exclusion zone around the wreck also remains in place.
