Pioneering Spirit Gets a Scrub Down

almost zero underwater visibility, the Fleet Cleaner was still able to perform the hull cleaning thanks to an in-house developed navigation and tracking system.Fleet Cleaner cleaned most of the fouled area of the hull alongside various simultaneous operations such as the removal of the pipelaying stinger and placement of a heavy lifting crane.Pioneering Spirit continued its voyage after six days in port and will now go to work lifting the 26,000-metric-ton processing platform and then the the 18,000-metric-ton living quarters topside for Johan Sverdrup

MTR100: The Ones to Watch

;s motto for Aquanaut is ‘mouse clicks not joysticks’.Led by Aquanaut, HMI says it intends to continue developing novel subsea capability and other robotic technology for use in oil and gas and defense applications with an objective to increase reliability, efficiency, capability and safety.Stinger Technology: Small But Well FormedStavanger, Norway, based Stinger Technology, is something of a boutique firm in the subsea space. It’s a small firm – with seven staff – but this year it’s been making ingress into subsea docking station technology, with support from Norway&rsquo

devices in to the same sockets in our homes. To this end, Statoil has a roadmap to see a field-proven vehicle agnostic docking station on a subsea production system in 2020-23, ready to pilot a UID that can swim autonomously between stations and perform survey and IMR tasks.In fact, Norwegian company Stinger is developing a UID docking station able to support any resident vehicle. Bjarte Langeland, CEO at Singer, says the company is designing two systems: a UID docking station and its “little sister,” a plug socket, which can support multiple power and communications needs but with a smaller

Dual GyroUSBLs for Allseas' Lorelay Stinger

;s GyroUSBL acoustic positioning technology for two systems for its 236 meter long lay vessel Lorelay.Used in conjunction with a Ranger 2 USBL (Ultra-Short BaseLine) topside which also formed part of the order, the GyroUSBL transceivers will be installed on the end of the Lorelay’s stinger to acoustically track a remotely operated vehicle (ROV) deployed to ensure a pipe is accurately touching down in the permitted corridor.USBL transceivers are routinely deployed through the hull or over-the-side of a vessel, enabling targets to be tracked below, to the side and far behind.

A Small Solution Solves a Big Problem

A clever idea has found a way to penetrate the labyrinth inside offshore production tanks in search of environmental contaminates prior to decommissioning.   Saab Seaeye customer Stinger Technology, a Norwegian firm known for finding innovative ways to work in confined underwater spaces, managed to squeeze a unique underwater robotic systems configuration loaded with sampling technology through a 150 cm square hatch to search the tank's internal maze of baffles, and navigate along 25.5 cm diameter pipe-runs of curves and bends.   Stinger's idea turned the already compact remotely operated

Custom ROV Solution for Stinger Technology

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 percent licensee of the Siri licence. The Siri platform is also host for the nearby Nini, Nini East, Cecilie

Trelleborg Launches Subsea Vibration Suppression System

Trelleborg’s offshore operation  launched an innovative new vortex induced vibration (VIV) suppression system. The Tri-Strake Combi, developed to complement the high performance S-Lay capable Tri-Strake Stinger system and the cost effective Tri-Strake Lite system, not only eases installation but provides added resilience and load bearing capacity, including stinger installation loads. Jonathan Fox, Senior Product Development Engineer for Trelleborg’s offshore operation, said: “Pipelines unsupported over free spans, such as steel catenary risers and rigid steel flowlines, are

The Pro 4 “resident ROV” was deployed off the coast of Stavanger, Norway, but operated mainly from Stinger’s offices which are located nearly 250 meters inland. The ROV remained powered on and in full

Global 1200 is a customized version of the Ulstein Sea of Solutions' SOC 600 design.

Technip Upgrading ‘Global 1200′ Vessel

June 2011. The dynamically-positioned (DPII) Global 1200 is a combined derrick/pipelay vessel, and is a customized version of the Ulstein Sea of Solutions’ SOC 600 design. The design incorporates an AmClyde PC-37 post crane on the aft and a centre firing line on the freeboard deck and a rigid stinger at the stern. The vessel has a lifting capacity of 1,200 tonnes, 400 tonnes deep water lowering system capacity, and is capable of operating in up to 3000 metres water depth. Global 1200 measures 162.3 m overall, with length (Bpp) of 150.34 m, breadth (moulded) of 37.8 m, depth to main deck (moulded)

StingBlade bits increase run length and ROP while delivering improved steering response in directional applications.

Schlumberger Debuts StingBlade Bit

, president, Bits & Advanced Technologies, Schlumberger. “StingBlade bits have greater durability in hard and inter-bedded formations when compared to conventional PDC bits, enabling an increase in the frequency of drilling an entire section with one drill bit.” StingBlade bits use Stinger* conical diamond elements optimally placed across the bit face. The conical shape of Stinger elements, with improved impact and wear resistance, induce high point loading on the formation, enabling increased run lengths and higher sustained ROP. In directional applications, the new drill bits cut

The HUGIN Autonomous Underwater Vehicle is the most successful AUV available in the commercial survey industry.

Leading Survey Providers Choose HUGIN AUV

Subsea AS of Bergen Norway has also recently ordered another HUGIN AUV System that will add to the company's growing subsea survey capability. The newest addition is rated to 3,000 meters and carries a range of sensors making it capable of completing several tasks in parallel. The launch and onboard Stinger is designed to operate from ships with freeboards of up to 5 meters in up to Sea State 5, making it highly flexible to use. “DOF Subsea’s newest HUGIN addition is very flexible. This gives the company several areas of usage, including geophysical surveys, inspection of subsea facilities

To enter that market we first closed small deals and now we’re negotiating on a completely different basis.” Since 2012, Saipem has been operating the MV Castorone, a pipelay vessel with an overall length of 330 m (1,082 ft), excluding stinger and DP 3 capable. The Castorone was classed by ABS and is also Ice classed, capable of berthing 700. The Castorone is currently the largest PLSV at sea and is officially classed as a PCV (Pipelay Crane Vessel). It was designed to transit at speeds of up to 13 knots, allowing it to reduce the

Workers weld the tubes in place together in only a few minutes. The pipe curves downward from the stern over the stinger through the water until it reaches the "touchdown point," or its final destination on the seafloor.
