Our Services
For ship structures and industrial equipment, we select the method according to the material, defect type, access and reporting requirement. With suitable planning and permissions, measurements can be carried out in port, at the shipyard or while the vessel is underway.
Ultrasonic Thickness Measurement
Ultrasonic thickness measurement (UTM) is based on the round-trip travel time of sound through a material. The measurement plan is prepared according to structural characteristics, previous survey records and the technical specification. Following instrument and probe checks, results are recorded with their measurement locations.
ROV Underwater Inspection
An ROV (Remotely Operated Vehicle) is an underwater vehicle controlled by an operator at the surface. Cameras and lighting capture damage, coating condition and signs of corrosion. The inspection plan is defined according to water conditions and access to the structure.
Eddy Current Testing (ET)
Eddy currents generated by the probe are affected by discontinuities and changes in material properties. This electromagnetic response is compared with suitable references. The probe and technique are selected according to conductivity, magnetic properties, geometry and the discontinuity sought.
Underwater Ultrasonic Thickness Measurement
Ultrasonic thickness measurement is integrated into ROV inspection using suitable equipment and a probe deployment system. Surface cleanliness, coating, probe contact and vehicle positioning are assessed before inspection. Only valid ultrasonic responses are recorded as measurement results.
Advanced Ultrasonic Testing
PAUT (Phased Array Ultrasonic Testing) electronically steers the sound beam to different angles and focal points. TOFD (Time of Flight Diffraction) evaluates the travel time of sound diffracted by discontinuities. The techniques are applied individually or together according to material, thickness, geometry and access.
Industrial Rope Access
Rope access is a means of access used for UTM, visual inspection and suitable NDT applications. Planning considers anchors, weather, the work area, falling object risks and rescue arrangements.
Elios 3 Drone Inspection and UTM
The Elios 3 UT payload measures the remaining wall thickness of metal structures by placing a probe in contact with the surface. Measurements are recorded with A-scan data and linked to measurement points on the structure using LiDAR localization. Visual inspection and UTM are carried out within the same inspection plan.
Conventional Non-Destructive Testing
VT examines accessible surfaces, while MT examines surface and near-surface indications in ferromagnetic materials. PT assesses surface-breaking discontinuities on clean, non-porous surfaces; UT assesses discontinuities within materials. The method is selected according to the material and inspection purpose.
Radiographic Testing
Radiographic testing (RT) relies on differences in radiation transmission through a material. Exposure geometry and imaging technique are defined according to material, thickness, access and required image quality.
Hatch Cover Tightness Testing
In ultrasonic testing, sound from a transmitter inside the hold is measured with a receiver around the hatch cover. Following equipment checks and reference measurements, the cover perimeter, seals and accessible joints are inspected.
Thermal Imaging and Inspection
Thermography images infrared energy emitted by surfaces. Electrical panels, connections, mechanical components and insulated surfaces are examined under suitable operating conditions. Emissivity, reflections, ambient conditions and equipment load are considered in the assessment.
Video Borescope and Borescope Inspection
Accessible internal areas of engines, pipes and enclosed components are imaged using suitable optical systems. Probe diameter, length, viewing direction and lighting are selected according to geometry and inspection purpose. Deposits, wear and surface damage are recorded.
Metallurgical Verification and Analysis
PMI (Positive Material Identification) determines alloy composition using an appropriate analytical technique. Hardness measurement assesses the material's local mechanical response. Methods and references are selected according to material type, surface condition and the property to be verified.
Vibration Analysis and Condition Monitoring
Measurements are taken at defined points and in defined directions on equipment such as pumps, motors and fans. Data is examined alongside speed, load, mounting conditions and historical records. Indications of imbalance, misalignment, looseness and bearing issues are assessed.
Low Location Lighting (LLL)
LLL systems make escape routes identifiable at low level. The layout, continuity and surface condition of photoluminescent markings are inspected. Luminance is measured under defined conditions; the inspection scope for electrical systems is specified separately.
Ultrasonic Weld Testing
Reflections within the material of high-frequency sound waves transmitted by the probe are evaluated. The probe and scan plan are selected according to material, geometry, weld type and access. The instrument and system are checked against suitable references before inspection.
Surface Roughness Measurement
The measurement method is selected according to surface preparation and the technical specification. Roughness parameters such as Ra and Rz are assessed on machined surfaces; the surface profile of abrasive-blasted surfaces is assessed before coating. Results are compared with the limits specified for the surface.
Paint and Coating Thickness Measurement
Non-magnetic coatings on ferromagnetic substrates are measured using the magnetic method; insulating coatings on non-ferrous metals such as aluminium are measured using Eddy Current. A probe suited to the substrate and coating is selected. Measurements are taken in the planned areas after instrument verification and adjustment checks.
Hull Supervision
Work on hull plating, decks, tanks and structural members is monitored against project drawings and technical specifications. Inspection stages are coordinated between the shipowner, shipyard and surveyor; UTM and NDT results are linked to the relevant fabrication or repair areas.
Shipyard Period Hull & Machinery Consulting
Existing survey, maintenance and measurement records are reviewed to clarify the work scope and priorities. Work on the hull, main and auxiliary machinery and associated systems is monitored against the shipyard schedule, manufacturer instructions and project requirements. Technical communication between the shipowner, shipyard, service teams and surveyor is supported.
Composite Inspection
Ultrasonic testing and advanced NDT techniques such as PAUT are used on glass- and carbon-fibre-reinforced composites, as appropriate for the material. The inspection plan considers the laminate arrangement, core material, thickness and access conditions. The location and extent of indications are evaluated in ship and yacht hulls, structural panels and accessible repair areas.
Condition Assessment Survey (CAS) — Hull & Machinery
A Condition Assessment Survey (CAS) establishes a structured picture of a vessel's condition before dry docking or a major maintenance period. UTM and NDT results are reviewed with corrosion, coating breakdown, deformation, damage and weld discontinuities. Existing records, field findings and maintenance priorities are combined for main and auxiliary engines, piping systems, pumps, valves, propulsion and steering equipment.
