Offshore Survey Vessels: Ready for Faster Sensors

may or may not use robotics. If robots are present, value on that operation is likely based on effectiveness or safety rather than efficiency.For example, carrying a 3000m depth AUV on the back of our 140’ survey vessel is certainly possible (lets carry 4). We have a fantastic launch and recovery stinger to do that. The reality is, recovering costs associated with buying or leasing the AUV more than triples the project cost compared to the old fashioned (and reliable!) hull or pole-mounted MBES. We’d never win the bid, plain and simple, if we are trying for any actual ROI, with an AUV. In

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

Unmanned Vehicles May Soon Take Up Residency Subsea

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. However

HUGIN AUV Now Available in a Turnkey Package

AUV comes preinstalled with a payload of navigation, communication and hydroacoustic equipment, including a Kongsberg EM 3002 multibeam echo sounder, EdgeTech Side Scan Sonar and EdgeTech Sub Bottom echo sounder. The complete package also includes a 20ft storage and shipping container, single stage stinger for easy launch and recovery, operator station, battery charger and tow fish and winch for communication.    “While providing significant cost savings, the customer can also be confident that the package provides high-end capabilities for multiple applications, backed-up by KONGSBERG&rs

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

ROV Put to the Test

Vehicle (ROV) spent 19 months operating continuously in the North Sea, in what is believed to be the longest uninterrupted deployment of a single ROV of any class, according to the company Put to the Test The operation began in November 2013 as an experimental emergency preparedness solution for Stinger Technology AS, a subsea services provider for the offshore oil & gas sector. 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
