Stinger wins Dong Energy contract in Danish sector
Specialised underwater robotics technology is to be developed and offshore subsea operations provided by Stinger
Technology AS under a contract awarded by Dong Energy. This assignment includes
environmental sampling and inspection inside the Siri platform’s oil storage
tank. Engineering and planning starts in March, with offshore campaigns planned
for this summer and autumn.
Siri is located in block 5604/20 in the
north-western part of Denmark’s North Sea sector, about 220 kilometres from the
Danish coast. The Siri platform came on stream in 1999. DONG Energy is 100%
licence holder of the Siri licence. The
Siri platform is also host for the nearby Nini, Nini East, Cecilie and Stine
fields. The storage tank measures 50 x 66 metres and is 17.5 metres high, with
a designed storage volume of 50 000 cubic metres. It is split internally into
16 compartments, some of which are only accessible through a 10-inch jumper

The challenge was to get into a tank structure, through a 30 cm predrilled hole, and clean welds for close visual inspection and non-destructive testing. The solution was to build a small but powerful ROV around a set of high-pressure nozzles. It has proven to be very effective and are currently on assignment for customers in the North Sea. The system is based on Stinger's ARROV architecture with remote control from the surface.
More than 450 delegates attended the biggest ever single gathering of international subsea robotic drone systems for use in the oil and gas industry the 2.nd. - 3.rd. October at TAU close to Stavanger. In addition, aerial drones, subsea seawater injection and a floating wind power research hub was demonstrated.
