MacArtney Supplies Specialized Underwater Robotics Technology to Stinger, Norway

Stinger Technology AS has taken delivery of a customized Seaeye Falcon ROV to be used for offshore subsea operations under a contract awarded by Dong Energy.

The assignment includes environmental sampling and inspection inside the oil storage tank of the Siri platform. Siri is located in block 5604/20 in the north-western part of Denmark’s North Sea sector, about 220 kilometers off the Danish coast. Production on the Siri platform first started in 1999.

DONG Energy is 100% licensee of the Siri license. The Siri platform is also host for the nearby Nini, Nini East, Cecilie and Stine fields.

The storage tank in question measures 50 x 66 meters and is 17.5 meters high, with a designed storage volume of 50,000 cubic meters. It is split internally into 16 compartments, some of which are only accessible through a 10-inch jumper pipe.

Scope of supply provided by MacArtney

Stinger selected the Seaeye Falcon ROV in order for it to perform as a carrier for a small VideoRay vehicle which is small enough to go into the different compartments of the tank. Therefore, they developed a TMS for the purpose of mounting it under the Falcon ROV carrying the VideoRay umbilical. The Falcon has therefore been supplied in a customized version with add-ons such as additional power and electric motor for driving the TMS. The scope of supply also includes an extensive spare parts package, FAT and a technical training course. The FAT and training were held at the facilities of MacArtney Norway in Stavanger.

“Stinger is a very innovative company that really thinks out of the box when it comes to solving complex challenges, states Mats Ekström, Managing Director of MacArtney Norway. That is why we are so fond of doing business with this company, which challenges us on our competences and enable us to demonstrate our expertise and ingenuity mastering customer requirements for technically advanced solutions.”
