The oil company announced on its website that, after a hole was discovered in the rig’s ballast tank, causing the rig to tilt 3-4 degrees, the crew of 374 have mustered at the lifeboat stations and evacuation by helicopter is taking place.
“The rig’s stability is now re-established” Statoil said and added that Floatel Superior would be towed to land in due course.
Statoil has set up a personnel reception centre in Kristiansund. Six helicopters and an emergency response vessel have been deployed in order to assist the rig. In addition, an anchor handling vessel will be dispatched to inspect the damage.
Owned by the Swedish company Floatel, the Floatel Superior is a dynamically-positioned (DP-3) semi-submersible facility with a living quarters module aft and an open work deck forward. The flotel can accommodate 440 people in single cabins when operating on the Norwegian shelf.
The PSA Norway in July 2012 granted consent to Statoil to use the flotel at Njord Field in the Norwegian Sea.

For the very first time, remote-controlled machines and an underwater welding robot have installed a new tie-in point on a live gas pipeline, without the pipeline being prepared in advance.

These types of operations can save Statoil lots of money in the long run.
The hot tap installation is the first to be carried out in connection with preparations for Åsgard subsea gas compression in the Norwegian Sea, and thus also represents a milestone for the project. The tie-in point was welded on to the Åsgard B production flowline at a water depth of 265 metres.
After ten days on the field, the hot-tap operation team on board the Technip-owned vessel Scandi Arctic could confirm success in the pioneering operation.

“For a subsea engineer, this can be compared with landing on Mars,” says Kjell Edvard Apeland. He is project manager of the remote-controlled hot tap development in Statoil and head of the operation on the Åsgard field.
Simply explained, a remote-controlled hot tap operation consists of a robot welding a T-piece on to the pipe, while gas is flowing through it. When that has been done, a remote-controlled drilling machine will drill holes in the producing pipeline, with no effect on pressure and production.
“When the compressor module and the manifold for Åsgard subsea compression are installed next year, we will connect the pipeline from these to the hot-tap tie-in point,” says Apeland.
The Åsgard subsea compression project will be realised in 2015, as the first of its kind in the world. Compressors will be installed on the seabed, instead of on a platform. This will improve recovery from the Mikkel and Midgard reservoirs by around 280 million barrels of oil equivalents.
Hot tap technology is a technological breakthrough, and a door opener for developing marginal fields, as well as extending the lifetime of other fields.
The ability to connect anywhere on a pipeline, without stopping production, yields considerable flexibility and significant savings.

“Since we will be connecting a new compressor station on the seabed to an existing pipeline system on Åsgard, it is very beneficial to use the hot tap technology to avoid disrupting production,” says Torstein Vinterstø, portfolio manager for subsea compression projects in Statoil.
“The savings are measured compared with what it would have cost to perform a similar operation, including shutting down production in the pipeline we were working on. This would also have taken much longer than the ten days we spent now – possibly as long as three months,” he says.
The method was developed by Statoil, and there is no comparable technology.
The work to develop the technology started in 1999, and was developed in Statoil’s pipe technology environment at Killingøy outside Haugesund. Statoil’s expertise in tie-in and repair of pipelines is gathered there.
Open and constructive cooperation with our key suppliers has been instrumental in achieving this.
Statoil has already thoroughly tested the hot tap technology, with good results. Remote-controlled hot tap has previously been performed on Tampen Link on the Statfjord field in the North Sea and on the Ormen Lange field in the Norwegian Sea, but then the T-piece had already been installed on the gas pipeline in advance.

Asia – SouthEast
Sep 13, 2012 – The Gurame SE-1X well is expected to spud towards the end of September, according to MEO Australia. Success of the appraisal well could lead to early development of the Gurame oil and gas field situated offshore northern Sumatra in the Seruway PSC. The well was identified via 3D seismic as the lowest risk drill-ready candidate with the highest potential for commercial development. Drilling will be undertaken by the Hercules 208 (200′ MLC). Two attractive targets in the well, the Baong and Belumai reservoirs, are expected to be naturally fractured and gas bearing. These attributes should improve the possibility of achieving commercial flow rates. MOE maintains a 100% interest in Seruway.
Project Details: Gurame
Sep 12, 2012 – The Berangan-1 well has proved to be Lundin Petroleum‘s third gas discovery in block SB303 offshore Malaysia. The well was drilled in 229 feet of water to a total depth of 5,607 feet by the West Courageous (350’ ILC). Data acquired from the well indicates a 541 foot gross continuous gas column in mid-Miocene sands. While Berangan-1 is the third gas discovery in SB303, it is the fourth in the contract area. Each of the 4 gas discovery lies within a 6 mile radius.

Sep 12, 2012 – Shell’s much anticipated Chukchi Sea drilling campaign is underway marking the first attempt in 20 years to explore offshore U.S. Arctic petroleum resources. Currently, the Noble Discoverer (mid-water drillship) is being used to drill the mud line cellar and top-hole sections of the first well. This is expected to take two weeks, after which the Discoverer will either continue drilling the Burger prospect or will move to another location to drill the top-hole section. Part of that decision will rest on whether or not the company is able to obtain a permit to drill past the surface sections into the oil bearing portion of the well. Shell has plans to drill three wells in the Chukchi Sea and two wells in the Beaufort Sea if the weather cooperates.

S. America – Brazil
Sep 13, 2012 – Vanco is preparing to move the GSF Arctic I (mid-water semisub) to drill its Canario prospect on BM-S-63. This is the second well in their three-well program offshore Brazil. Drilling is expected to commence in approximately two weeks.
Project Details: Canario
Sep 13, 2012 – Vanco Energy’s Sabia well reached a depth of 13,779 feet when a decision was made to stop drilling short of the proposed depth of 14,717 feet. Based on current well data, the discovered volumes are at the low end of the pre-drill range estimate. While the well encountered an active petroleum system, the commerciality of the discovery cannot be firmly made at this time. The information obtained from the well is likely to have a positive impact on the next two prospects to be drilled – Canario and Jandaia.
Project Details: Sabia
Sep 12, 2012 – Petrobras has announced the start of oil production at the Baleia Azul presalt field in the offshore Camps Basin. First oil from the field is being pumped aboard the Cidade de Anchieta FPSO. The Cidade de Anchieta is one of two new production systems that Petrobras will put into operation in 2012. Initial production at Baleia Azul is a good sign for Petrobras whose oil production has taken a hit this year due to maintenance and unexpected shutdowns. The company has also announced plans to bring Bauna and Piracaba fields online in October. Petrobras holds a 100% stake in the fields.

A letter sent to the relevant companies points out that recovery from producing fields is an important commitment area for the Norwegian Petroleum Directorate. An increasing percentage of the oil production on the Norwegian shelf comes from subsea wells, and the number of wells is increasing. The NPD has noted that it could be challenging to both drill new sidetracks from the subsea wells and carry out maintenance.
“That is why the Norwegian Petroleum Directorate is concerned with finding good solutions that can contribute to maintaining or increasing production from subsea wells,” says Torsten Bertelsen, director responsible for the Norwegian Sea and Barents Sea.
Statoil has long worked on a new type of rig for subsea wells, a so-called category B rig. It is permanently equipped for cables, coiled tubing and slim hole drilling and is specially adapted to well intervention campaigns. This type of rig can be used on multiple fields with subsea wells.
Use of such a rig will contribute to improve rig capacity, increase the number of subsea wells and thus improve recovery from subsea wells.
In the letter to the licensees the Norwegian Petroleum Directorate asks the companies to support Statoil’s project or to present alternative measures or projects that can yield similar effects.
“A cooperation on the new rig type across production licences is considered good resource management,” says Bertelsen.
