Offshore, Thermal Imaging

In early June Geo Therm Limited surveyors performed our very first electrical biased thermographic survey on the new build rig ENSCO 121 off Den Helder, Netherlands. The survey mobilisation began at Norwich Int. Airport and a short hop to Schipol Int. Airport using the KLM city-hopper service, thereafter onto the punctual Dutch rail network to Den Helder for a overnight stay at the eclectic Hotel Den Helder and an early helicopter flight out to the Ensco 121 some 120NM north-west of Den Helder.

The Ensco 121 is a Keppel FELS KFELS Super A Class Ultra Enhanced, independent leg, self elevating, cantilever jack-up drilling rig purposely designed to operate in harsh environments, and ideally suited for use in the North Sea where drilling the most demanding multi-well programs for ultra-deep and ultra-reach wells are becoming the norm, as needed for the current 2 year contract for the German exploration and production company Wintershall.

The Ensco 121, is the second of four new ultra-premium harsh-environment jack-up rigs in the ENSCO 120 Series. Built by Keppel FELS at the Keppel FELS, Singapore shipyard and delivered in 2014 it has an ABS Classification, a IMO number 9621481 and capable of drilling down to depths of 40,000ft in 400ft of water depth.

The rig thermographic survey was completed within time and budget moreover performed without incident; following the rig’s exacting PTW, JSA’s and procedures and when necessary donning our full arc flash suits to minimise personal risk from those few places where infrared windows were found wanting. This type of third party annual survey is necessary to support the Ensco 121 rigorous PM demands to identify extreme temperature anomalies in electrical equipment, thereby preventing outages and downtime during high load drilling operations.
