Stranding Transocean Winner, 8 August 2016

Introduction

On 8 August 2016, the Marshall Islands registered semi-submersible rig Transocean Winner grounded on the Isle of Lewis following the loss of tow from the Dutch registered tug ALP Forward. The tug and tow was on passage from Stavanger, Norway to Valletta, Malta when it encountered severe weather west of the Hebrides. The effect of the wind and waves on the rig led to the loss of ALP Forward’s ability to control the direction and speed of the tug and tow. After being dragged backwards by the tow for over 24 hours, the tow line, weakened by the repeated sudden loadings, parted and the tug was unable to pick up the emergency towline.
 
The British Marine Accident Investigation Branch (MAIB) conducted an investigation into this accident and published the report on 7 September 2017. The Dutch Safety Board was involved as Substantially Interested State.
