13 The first targetless DP sensor optimised for positioning and station keeping at a wind turbine Standard navigation and positioning techniques used in offshore oil and gas are not optimised for navigating inside a wind farm. Unlike an offshore supply vessel servicing an oil platform which may have 1 or 2 approaches per day, wind service vessels may visit as many as 50 wind turbines in a single day. This requires fast and efficient turnaround times without compromising safety. RangeGuard Monopole System A new type of radar sensor has been developed which does not use a dedicated target rather it uses the local environment as its target; typically the leg or tower of a wind turbine. This removes the need for physical targets to be installed which makes the vessel completely independent and can increase both safety and decrease turnaround times. Measures range to the nearest object Sends out a radar signal and detects the radar reflections from the environment An accurate range and bearing measurement is displayed on the Dashboard user interface All weather radar technology Fixed beam radar sensors operating in the license exempt short range device band of 24GHz SceneScan System Guidance Marine has developed a new version of its targetless laser sensor which is specially designed for use on wind farm Service Operation Vessels (SOV s). The new version of the software allows the sensor to measure range and bearing to the offshore wind turbine without the use of targets: - No expenditure on targets - No targets so no maintenance costs of targets - Faster vessel turnaround times - Monopole tracking gives much greater positioning robustness for wind farm support vessels - Use in conjunction with RangeGaurd Monopole to be completely independent of targets and fulfill 2 modes of redundancy - Can be switched between monopole operation and other asset tracking operation with a simple switch 13

14 The RangeGuard Monopole system uses direct radar reflections from the transition piece rather than specific targets mounted on a structure The first targetless DP sensor optimised for positioning and station keeping at a wind turbine Readout of distance up to 300m RangeGuard sensor system installed on side of vessel Vessel A Targetless Future Guidance Marine are the first company to offer a local DP Position Reference Sensor (PRS) solution that removes the requirement for targets altogether. The system consists of a minimum of 2 RangeGuard sensors connected to a control unit which in turn is connected to the bridge and the DP system of the vessel. The small light weight radar sensors are mounted onto the side of the vessel pointing in the direction of the transition piece and simple geometry determines the range and relative position of the vessel. Bernhard Schulte have installed a full DP enabled system on their SOV Windea La Cour. Sensors were installed on the vessel at the yard on the starboard side of the vessel - the same side as the motion compensated gangway. Turbine 14

15 Simple Installation RangeGuard Monopole Dashboard RangeGuard Controller Minimum of 2 RangeGuard Sensors Connected via Network User Interface Targetless positioning for wind farms has begun Easy to set up Dedicated Service Interface tool, maintaining the easy to use Dashboard interface for day to day operations. Sea trials have proven an environmentally referenced sensor system can be used for local position DP referencing. Being completely independent of mounted targets, and based on radar technology, it provides an additional input to the DP system. The RangeGuard Monopole system introduces a new method of data acquisition, thus is not having many common failure modes with DGPS or laser system. The common problems that occur with mounted targets are negated and maintenance of targets is no longer required

16 Vessel independent of installation (no dedicated targets required) No maintenance, reduced costs The first targetless sensor optimised for positioning and station keeping at a wind turbine The RangeGuard Monopole system consists of a minimum of two RangeGuard microwave marine range finding sensors mounted on the side of the vessel, pointing in the direction of the transition piece at the bottom of the wind tower. Simple geometry determines the range and relative position of the vessel to the transition piece which acts as the target which the system will report the range and bearing. Detects objects within 300m No moving parts Additional form of redundancy Reduce turnaround times RangeGuard Monopole DNV GL approved Applications: The RangeGuard sensor is suitable for vessels that approach wind turbines such as: Service operation vessels Crew transfer vessels Walk-to-work vessels Service & Warranty Supported by Guidance Marine s international network of service centres, The RangeGuard sensor is supplied by Guidance Marine with a 3 year warranty the longest warranty from any supplier. Delivering the future in dynamic positioning with consistently accurate products. 16

17 Automatic wave compensation Close range operation from 10m The standard laser sensor of choice by major DP Integrators The CyScan sensor is a high performance local position reference sensor specifically engineered for marine DP applications. Full 360º scanning Operating range up to 2,500m True ChartRange distance option DNV GL approved The sensor accurately measures the range and bearing to retro-reflective targets allowing for the calculation of vessel position and heading making it ideal for station keeping, or for accurately moving a vessel. Applications The CyScan sensor is suitable for applications which use fixed structures such as: Platform, offshore and multipurpose supply vessel operations Wind farm servicing Accommodation barge operation Crew boats station-keeping Heavy lift activities Dive and ROV support Fish farms The CyScan sensor is also suitable for DP applications with mobile structures such as: Track and ship-follow Shuttle tanker loading Pipe and cable laying Rock dumping Replenishment at sea Delivering the future in dynamic positioning with consistently accurate products. 17

18 The CyScan System The CyScan system has three main components: 1. CyScan Targets One or more targets are mounted on the wind turbine 2. CyScan Sensor The Sensor is installed on a vessel equipped with a DP system 3. CyScan Dashboard Software is used by the DP operator to control the CyScan Sensor. It runs on a marine processor installed on the vessel s bridge Unique Features High Laser Pulse rate 30kHz True multi-target operation gives relative heading Selectable tilt at 1 increments, including auto-adjusting option Robust construction for highest reliability Ease of use for quick set-up and operation Automatic dynamic pitch/roll wave motion compensation provides optimum target lock Sophisticated tracking algorithms reject false reflections Optimised optics protect against low sun and bright lights Interfaces to all known DP systems Tracking is not stopped when manually tilting ChartRange The CyScan sensor has the option to provide a direct horizontal distance (ChartRange ) to the reflectors. For certain precision positioning operations it is advantageous to have an indication of the horizontal distance to the target. The CyScan sensor can calculate this and provide a ChartRange output rather than the DirectRange output that is typically used for DP station keeping operations. DirectRange TM ChartRange TM CyScan Dashboard The CyScan Dashboard is an innovative touch screen interface that enables DP operators to use the CyScan sensor safely whilst providing optimum positioning performance. The CyScan Dashboard is a state of the art solution to the control of the CyScan Mk4 sensor. The same user interface philosophy is used on all of our systems, helping to make sure that Guidance Marine trained operators will already be familiar with controls. 18

19 The safest laser sensor of choice. The CyScan AS sensor is a high performance local position reference sensor specifically engineered for marine DP applications. The sensor accurately measures the range and bearing to retro-reflective targets allowing for the calculation of vessel position and heading making it ideal for station keeping, or for accurately moving a vesel. Absolute Signature (AS) resolves long-standing, common industry challenges by providing an improved performance during target identification, acquisition and tracking. Applications The CyScan AS is suitable for offshore installations such as: Platform, offshore and multipurpose supply vessel operations Wind farms servicing Accommodation barge operation Crew boats station-keeping Heavy lift activities Dive and ROV support Fish farms The CyScan AS sensor is also suitable for DP applications with mobile structures such as: Track and ship-follow Shuttle tanker loading Pipe and cable laying Rock dumping Replenishment at sea Guaranteed signature lock between the CyScan AS sensor and the AS prism target Likelihood of incidents due to false reflections are reduced to zero AS Dashboard user interface automatically identifies AS Prism targets which reduces the workload of the DPO in identifying and selecting targets Immediate and definitive elimination of reflective clutter Delivering the future in dynamic positioning with consistently accurate products. 19

20 The CyScan AS System 1 The CyScan AS system has three main components: 1. CyScan AS Targets One or more targets are mounted on the fixed platform or mobile object 2. CyScan AS Sensor The Sensor is installed on a vessel equipped with a DP system CyScan AS Dashboard Software is used by the DP operator to control the CyScan AS Sensor. It runs on a marine processor installed on the vessel s bridge Unique Features Positively identifies AS targets Twin lasers pulsing at 30kHz True multi-target operation gives relative heading Ability to add additional targets to a multitarget session without interrupting tracking Robust construction for highest reliability Ease of use for quick set-up and operation Automatic dynamic pitch/roll wave motion compensation provides optimum target lock Sophisticated tracking algorithms reject false reflections Optimised optics protect against low sun and bright lights Interfaces to all known DP systems Tracking is not stopped when manually tilting CyScan AS Dashboard How does Absolute Signature (AS) work? The AS prism has a black tinted lens filter which gives it a unique signature that the CyScan AS sensor can exclusively identify as the AS prism target. CyScan AS sensor used with any reflective target detects both laser reflections The CyScan AS sensor can be used like a standard CyScan if an AS prism is not available. CyScan AS sensor used with AS prism target only detects one laser reflection - it can unique ly identify the target: CyScan AS Targets Yellow Diamond / Black Outline: Tracking AS Prism Grey Diamond / Black Outline: Tracking Non AS Prism Yellow Circle / Black Outline: AS Prism reflection Grey Circle / Black Outline: Non AS reflection The CyScan AS Dashboard is an innovative touch screen interface that enables DP operators to use the CyScan AS sensor safely whilst providing optimum positioning performance. The CyScan AS Dashboard is a state of the art solution to the control of the CyScan AS sensor. The same user interface philosophy is used on our Artemis and RadaScan systems, helping to make sure that Guidance Marine trained operators will already be familiar with controls. AS prism targets work with all other laser sensors and perform like any other standard prism target. 20

21 The next generation in laser reference technology; delivering new levels of confidence The Absolute Signature (AS) Prism is designed to endure the harsh environment of offshore weather conditions. The bright coloured exterior allows vessels to easily identify the visual target from a distance. Combined with the latest innovative technology, the AS Prism delivers a level of confidence previously unachievable in laser position reference sensor positioning. Applications AS Prisms are suitable for applications which use fixed structures such as: Wind turbines Oil platforms AS Prisms are also suitable for applications with mobile structures such as: Track and ship-follow Shuttle tanker loading Pipe and cable laying Rock dumping Replenishment at sea AS technology benefits: Guaranteed lock between the sensor and target Improves visibility with automatic target identification and acquisition Reduces turnaround time increases operational efficiency Eliminates the possibility of false reflection walk-off incidents Simple and reliable operator experience Delivering the future in dynamic positioning with consistently accurate products. 21

22 Key Prism Features Prisms reflect almost all of the light received and provide the maximum signal strength allowing for longer range in deteriorating visibility. They are typically mounted in clusters to provide a greater angle of visibility and/or to increase the signal response in locations prone to low visibility. Reflective Prisms are becoming a standard choice for laser targets for offshore fixed assets as they are smaller, and are more robust than a tape target. UV degradation and salt build up will reduce the reflectivity of tape targets over time and consideration should be given to mandatory use of AS Prisms for instrumentation. Drop down bracket suits varying rail diameters Side slots for 2.5 inch U-bolts or existing straps to fit varying rail diameters Fitting against posts keep the target vertical Drop Down Rail Installation U-bolts or strap to post options Compatible with all laser sensors High visibility, easy to identify Robust housing design suitable for handovers Easy drop on rail mounting Suitable for long-term wall or handrail mounting Increased range and durability over tape targets Handles on both ends Bottom handle enables the unit to stand Security lanyard included in the purchase of a Rugged Prism AS Prism Angular visibility 195 Weight: 12.5kg (boxed) Dimensions: 560 x 240 x 340mm (boxed) Additional Installation Options Rail Unistrut Install (Unistrut parts not supplied) Railing Post Option The new easy drop on design allows the prism to hold its position on a rail without the need of u-bolts for temporary use. 22

23 Operating range up to 200m Close range operation from 10m The first targetless laser position reference sensor The SceneScan System is a high accuracy rotating laser sensor to provide positional information to allow automated approach and/or station keeping relative to a structure or vessel. It is designed to be semi-portable and straightforward to operate. SceneScan provides tracking information relative to natural or man-made structures within the sensor field of view. It tracks by matching its current observation of the scene against a map generated from previous observations of the SceneScan. Full 360º scanning Automatic wave compensation Laser pulse rate 7.5kHz Class 1M laser classification Position off the Scene Interfaces to all DP systems Ethernet communication Applications Can act as an additional position reference sensor sensor, in critical rather than on joystick applications requiring increased redundancy such control. as dive support. Monopile tracking gives much greater positioning robustness for windfarm support vessels. In jack-up applications where positioning of targets can be logistically difficult the SceneScan can simply track from the legs. Target hand-over for traditional local position reference sensors can now be completed on DP with an active local reference Delivering the future in dynamic positioning 23

24 Dashboard and Service Interface Benefits The SceneScan Dashboard has been logically structured and carefully designed to provide a clear intuitive interface that maximises the opportunities of multi-touch user control and touchscreen technology.
