The salvage team on board the drilling rig, Transocean Winner, has increased to fourteen people as part of the ongoing salvage operation.
An additional six joined the rig by boat on Monday.
A pulley system has been rigged up on the headland to transfer food, water, supplies as well as sleeping bags and torches, across to the platform.
Two bottom tanks burst when rig went on the rocks resulting in a quantity of diesel spilling into the sea.
Smit Salvage has confirmed that the other pair of oil tanks in the hull are intact and plans are under way to pump the remaining diesel above the water line.
The salvors continue their damage assessment and preparation for the refloat.
Transocean continues to check and restore equipment and other essential services.
An AugustaWestland AW139 helicopter is now based in Stornoway to support the operation. A second aircraft, charted from Spain, has also been mobilised.
An exclusion zone of 300 metres remains in place around the rig covering the sea and air, which means no drones will be permitted in the area, providing a safe working area for the salvage team to work in.
The Scottish Operational Environment Group continues to support and closely monitor the incident. There are no reports of pollution.
