In mid June Geo Therm Limited surveyors performed the seventh consecutive annual electrical biased thermographic survey on the Diamond Offshore Drilling (UK) Ltd (DODI) semi-submersible rig the Ocean Guardian; a Earl & Wright Sedco 711 Series design rig, built by Scott Lithgow in Glasgow. Executing the survey during high load drilling operations for the oil major Shell.
Mobilised from Norwich International Airport for a overnight stay in Aberdeen before the early departure and first survey off the west coast of Ireland; flying on board a CHC EC225 helicopter out of Donegal. At altitude the scenic splendour of Ireland’s rugged coastline becoming ever more distant as we headed out over the Atlantic Ocean with nothing but an endless horizon to gaze upon and the Ocean Guardian and the Americas ahead of us, arriving on the rig one hour later and some 105NM south-west of Donegal.
After several days the survey was safely completed within time and budget, spurred on by the electrical departments keen desire to complete as much as reasonably practicable energised equipment during the drilling program. As per all our surveys they follow the rig’s Permit to Work and Job safety Analysis prerequisites and in this particular case compliance to the PM procedure set out in DODI’s ‘Global Excellence Management System’ (GEMS). These comprehensive set of procedures are designed to monitor, control and continuously improve the performance in the operational integrity, health, safety, environmental protection, regulatory compliance of the rig; and making our survey most streamlined.
