SLV-80 Subsea Laser Profiler

 

Our subsea laser profilers create better asset integrity and inspection reporting products. They eliminate the need for direct-contact mechanical calliper solutions and provide higher accuracy measurement 3D data - critical for safe offshore operations. Superior data quality generates value for our clients by reducing the need for manual intervention during post-processing. High survey speeds unlock further savings through reduced operational times. This value creation is significant compared to the profiler cost.

Subsea laser profilers create better asset integrity reporting products.

 

Savante manufactures subsea laser profiler products which are robust, immensely powerful and exceedingly fast.  Our subsea laser profiler solutions help ROV operators, trenching contractors and survey companies drive cost-effective and efficient execution of underwater survey operations by decreasing the cost of data capture, post-processing and analysis in the offshore environment.  We do this by raising the quality of measurement data at source, reducing the need for manual intervention during post processing and enabling the full potential of subsea vehicles to be exploited at much higher survey speeds.

 Savante's subsea laser technologies drive efficent underwater survey operations by decreasing the cost of data capture.  Laser mapping collects the highest possible resolution seabed data; vital for monitoring the condition of trench and buried products.

Reducing manual data-intervention starts with a better quality data source.

 

Manual review, interpretation and intervention on noisy acoustic profiler data is resource-intensive and a fundamental drain on productivity at sea.  It also results in poor delivery schedules for data to an operator.  Savante's profilers provide data at a quality sufficient for the automation of data processing operations using artificial intelligence, neural networking, task-focussed numerical algorithms and new workflows.  Our superior laser-scanned data reduces the administrative burden of post-processing the removal of noise from extensive acoustic datasets by a survey team and delivers new efficiencies in the time-management and focus of offshore expert witness surveyors.  Potentially achieving much more in a single shift or by decreasing labour costs, the use of laser profiler systems can also lead to an improved work-life balance for the operational team at sea, data co-ordinators ashore and better detection of changes in asset condition.  The latter is critical to an asset integrity manager and leads to better and safer management for an operator.

 

Unlock savings in cost-per-databyte using higher survey speeds.

 

We provide high speed subsea laser scanning technology to a variety of subsea contractors for use with high-speed ROVS, AUVS and bespoke towed-vehicles.  These businesses uniquely exploit higher survey speeds during extensive area surveys such as seabed mapping or pipeline survey operations and deliver lower data costs to their customers by minimising vessel usage or using multiple platforms simultaneously from a mother-craft.

Savante's laser profilers achieve class-leading speeds of measurement, high definition data and can be integrated with high resolution digital stills cameras and optical strobes to provide imagery and a high quality record of a survey area.

For many of these vehicles, the tether used to provide power and communications may be absent [AUV] or bandwidth limited [power over conductors used in towed fish].  This often places limitations on the volume of data that can be collected during an excursion.  Savante's laser profilers can be integrated with an optional subsea control module conducting recording, data processing and power management without user intervention. 

 

Safe - Efficient dimensional control without pre-engineering or calliper tooling.

Subsea dimensional control forms an essential component of retro-fit construction and inspection-repair maintenance operations; they often have rigorous tolerances and are often achieved using acoustic or bespoke, fabricated mechanical caliper tools.  In many instances, these are expensive workscopes and the size of a purpose-built caliper can be as large as the measurement requirement; this places practical limitations on these operations and requires significant engineering review to overcome potential access restrictions.  The potential fragility of a mechanical solution also exposes clients and operators to commercial risk and technical downtime if it becomes damaged and requires maintenance or replacement in field.

 

The 3D measurement data generated by Savante's laser profilers help ROV and survey businesses safely manage and simplify the execution of dimensional control projects by eliminating;

 

  • the cost and time associated with engineering and fabricating specific measurement tools,
  • conduct task-specific risk assessment and certification,
  • the logistics of transporting it to the worksite [which may be remote],
  • mobilisation on a vehicle.

 

In the case of belly-slung measurement tools, mechanical solutions degrade the vehicle flight characteristics; making a harder excecution offshore and a raised potential for incidents. 

 
 
 Subsea laser profilers deliver non-contact measurements in real-time from a remote safe location; this protects sensitive production items, such as this production riser, from collision with the ROV.

Subsea laser profilers deliver non-contact measurements in real-time from a remote safe location; this protects sensitive production items, such as this production riser, from collision with the ROV.

Savante's laser profilers support engineering measurements using direct point-to-point caliper measurements without the need for physical contact and from a remote, safe location.  This also minimises the risk of collision between an ROV and sensitive subsea assets,makes the internal components within structures such as overtrawlable protection structures or templates easily accessible but also enables operational efficiencies through extending the weather-handling capabilities of an ROV.  Our clients are able to avoid the engineering and fabrication effort, saving significant project costs and enabling measurement workscope oppportunities to be captured at much shorter notice.  A range of software-deliverable expansion packages are offered by Savante to our clients to add further project efficiencies in operations such as flange-to-flange spoolpiece measurement or using additional survey sensors such as LBL, INS or Gyros.

 

Value-Generating Features:

 

  • Reliable dimensional-control measurement data can be collected safely from an extended range of assets without the need for direct physical contact; a vehicle can acquire data from dangerous, difficult-to-access locations or from production-sensitive structures during periods of high sea-states and poor mobility from a farther-safer location. 

  • Enhances dim-con productivity, reduces cost and time constraints by eliminating the engineering effort to fabricate, test, transport, review and analyse the safety considerations of deploying large mechanical measurement solutions.

  • Delivers signficant value for operators of high speed subsea survey vehicles using high-speed 3D data capture performance whilst retaining superior measurement resolution and performance.

  • Integrated video capture capabilities leaves operators in no doubt as to the points of measurement and location of reportable anomalies by combining 3D data with a high quality digital stills image.

  • An entirely configurable subsea laser profiler means that only a single product is required for a wide range of measurement applications.  Additional cameras, laser modules and processor options are available to minimise the cost of ownership.

  • "Exo-sensory" subsea laser profiler can measure larger distances than a similarly sized mechanical calliper solution.
