The Nini East A Platform was installed in summer 2009 as a satellite platform to Siri. Nini East A is solely a production platform producing for Siri. Dong Energy A/S operates the Siri platform and the adjoining platforms.

The Nini East A is a B type topside comprising a helideck. The topside is installed on a mono tower three leg jacket structure. The jacket is installed on 59 m water depth 40 km northeast of Siri and 8.5 km north east of the existing Nini Platform.

The Nini is designed with a good caisson with room for 10 wells, 4 as production wells, 2 are injection wells, and the last 4 wells are either production or injection wells. As the risk of developing wax, scalding and corrosion are fairly high; injection of chemicals has been installed to prevent destruction of the pipeline.

The Nini East is connected by a multiphase pipeline to the Nini and further on to the Siri. Injection water and lift gas to the Nini East are provided from the Siri by two pipelines via the Nini.

Due to the design of the Nini East, a long line of alterations of the existing Nini was carried out so that production, water and lift gas could be pumped via Nini and further on to Nini East.

The Nini East Platform is remotely supervised and controlled from the Siri by means of the telemetri system Line of Light.

The topside and Jacket is designed by ISC Consulting Engineers A/S in cooperation with Semco Maritime A/S. The platform was manufactured by Bladt Industries A/S in Denmark. The topside and jacket were transported to the site on barge and lifted into position in June 2009 by the floating crane Thialf. The duration of the design and production has been approximately one year.

Gas Module Tyra West

The appraisal of the Halfdan NE gas reservoir and the European open gas marked intention have formed the initial basis for establishing a 26″ pipeline running 99 km from the Danish sector towards the Dutch sector vie the NOGAT F3 platform and further on to shore at Holland for distribution. The pipeline is owned by DUC and DONG Naturgas and is operated by Mærsk Olie og Gas A/S.

Halfdan BD

Halfdan BD platform is the latest addition to the Halfdan B Complex in the Danish North Sea. The platform upgrades the complex to manned operation and provides facilities to handle extraction of oil reserves with high water contents.

Dan FG

The latest platform installed in the Dan field in the Danish North Sea is Dan FG. This platform increases the 300 bar water injection in the old Dan and Halfdan oil fields, thereby maintaining the pressure from the oil production.

Dai Hung Mid Depth Buoys

Drilling for oil and gas in deep water is usually done by means of semi- submersible rigs. This is also the case in the Dai Hung oilfield, located in Block 05-01a, approximately 250 km of the coast of Vietnam at a water depth of approximately 110 m.

Tyra platform

Tyra Southeast B

During the summer of 2014 the Tyra Southeast B platform was installed on a 4-legged jacket as a satellite platform connected via a bridge to the Tyra Southeast A platform. The installation of the Tyra Southeast platform and bridge will maintain and increase the production from the Tyra Southeast reservoir, and create opportunities for future recovery of oil and gas from the Nana reservoir.

Maersk Drilling XLE Rigs

The Maersk Drilling XLE rigs is a series of four ultra harsh environment jack-up drilling rigs. The rigs were delivered from ship yards in The Far East and transported to Norway for a start-up stay for installation of Company equipment.

Maersk Drilling JU-rig

The YME field in Norway was redeveloped in 2008-2010 by Talisman. A storage tank was placed on the seabed 95m below sea level. An OD 5m caisson, protecting the future 9 conductors, connected to the tank, extended 25m above sea level.
