NLI and Ulstein showcase new derrick concept

Together with Ulstein Sea of Solutions, NLI are now well established in the derrick and drilling market and have developed an integrated derrick with drill floor system for installation on vessel decks.

“This type of drilling package is a familiar product on the global market, but this concept is unique in that it involves an integrated system providing several benefits and enhanced working conditions”, says Marketing Director Sigve Barvik at NLI.

The derrick system is equipped with cables and pipes integrated within its rear legs. This greatly reduces equipment maintenance requirements. A lift is installed in one of the front legs which can stop at six different levels – making it easier for workers to gain access with equipment during servicing. The system thus also enhances the safety of deck operatives. A further major benefit is that the upper derrick structure is retractable, allowing the vessel to pass below bridges without the need to dismantle any of the equipment.

The new derrick system is called Northern Light and was unveiled at the OTC oil expo in Houston in May this year. NLI and Ulstein showcased a physical model of the system at OTC, and the new concept attracted considerable attention. Several companies have already expressed an interest in the new concept and we will be following up these enquiries closely.

”We believe this system will make a big breakthrough in the global market”, says Barvik. “There are several competitive advantages in building a complete and integrated derrick. There are major advantages to a derrick with drill floor that can be hoisted on board a vessel in one lift, fully tested and ready for use”, he concludes.
