Two of four fuel tanks on Transocean Winner 'intact' | |
(about 5 hours later) | |
Two of four fuel tanks on the grounded rig Transocean Winner that were not previously possible to inspect have been found to be intact. | |
Last week it emerged that the two other tanks had been breached during the grounding and more than 12,000 gallons (56,000 litres) of diesel oil lost. | |
Eight experts scaled the rig at Dalmore beach on Lewis with ropes on Sunday and were able to check the two other tanks. | |
Six more workers are due to join them later this week. | |
Efforts are to be made to pump the diesel oil still in the hull, 137 tonnes, to other tanks above the waterline. | |
Moving the stricken rig is still weeks away, according to the official overseeing the salvage work. | |
Hugh Shaw, who is overseeing the salvage work, also said the workers on board would remain on the structure for the "foreseeable future". | |
A wire is to be run between the shore and the rig so supplies and equipment can be delivered to the personnel on the Transocean Winner. | A wire is to be run between the shore and the rig so supplies and equipment can be delivered to the personnel on the Transocean Winner. |

A 300m (984ft) exclusion zone remains in place around the rig covering both sea and air, which means no drones will be permitted in the area, although another aircraft has been brought in to help with the work. | A 300m (984ft) exclusion zone remains in place around the rig covering both sea and air, which means no drones will be permitted in the area, although another aircraft has been brought in to help with the work. |
