The vessel is based in the South East Asia Region and available for survey projects worldwide. Read more>> Single-beam echo-sounders Odom Hydrographic Echotrac and Hydrotrac Echotrac and Hydrotrac are high precision echo-sounders. Radiation frequency is 24 KHz and 200 KHz. Accuracy of depth taking makes 1 cm +/- 0.1 % from depth. They are intended for echo sounding on depths from 1 to 500 meters. Data collection can be carried out with Trimble HydroPRO software or QPS QINSy software. Side-scan sonars EdgeTech 4200 and C-Max CM-2 EdgeTech 4200 and C-Max CM-2 are well-reputed around the world side-scan sonars. Combined with EdgeTech Discover and QPS QINSy software they allow data collection in digital format and further processing in Triton Elics ISIS software with mosaic construction (seabed imagery) according to the data from unlimited quantity of survey lines. Multibeam echo-sounders Reson SeaBat-8101 and 7125 Multibeam echo-sounders are used for survey works on big spaces with assured complete cover of seabed, for collecting detailed information. Romona Inc is the first acquirer of Reson-8101 multibeam echo-sounder in Russian Federation. 101 beams of this echo-sounder allow to define seabed elevation in zone sevenfold wider than value of depth. For instance, if value of depth is 50m than coverage area would be 350m. Data collection and processing is carried out in QINSy software. Multibeam echo-sounder system Reson SeaBat-8101 conforms to IHO and USAGE Class 1 standards. Basic specifications:
Multibeam echo-sounder Reson SeaBat-7125 is used for survey works on large-scale offshore facilities. Basic specifications:
Acoustic Tracking Systems Sonardyne Fusion and TrackLink 1500 Acoustic tracking systems are designed for precise positioning of underwater objects, their parameters and motion trajectories relative to base vessel in real time. Romona Inc is the first acquirer of underwater sonar positioning system Sonardyne Fusion. Fusion USBL is the most perfect acoustic positioning system with ultra-short base created by Sonardyne Company. This system dedicated for positioning of underwater objects on up to 7000m depth. Key features:
The TrackLink systems are the world's best selling USBL acoustic tracking systems with fully integrated high speed acoustic communication capability. It is utilized for tracking of underwater equipment and other objects on up to 1000 m depth. Key features:
Satellite DGPS systems C-Nav and Veripos Ñ-Nav system is a totally new concept in DGPS. User can receive orbit and clock corrections via satellite channel instead of correction data for pseudorange to each GPS satellite. Therefore, quality of stationing doesn’t depend on distance between user and reference station. C-Nav service is avaliable all round the world and C-Nav's positioning is just as accurate in both marine and land environments. The system’s accuracy is 0.5m in high-precision mode and 1-2m in standard mode. Veripos system is a worldwide leader in high-precision positioning. Veripos provides service of differentiated GPS corrections for oil and gas industry. It also allows worldwide support services and data delivery for high-precision positioning programs. Veripos system includes satellite an HF receivers, single and double frequencies GNSS equipment and antennas. GNSS equipment includes RF range satellite-aided decoders (390 - 1550) MHz, GNSS receivers for NAVSTAR and GLONASS. DeltaFix, RadioLink and DeltaLink radio DGPS systems Differential corrections are transmitted via UHF and MF-range radio channels. In DeltaFix and RadioLink systems data are transmitted on two frequencies at one time to make them more fail-safe. DeltaFix range is 300 km, RadioLink range is 130 km and DeltaLink range is 20 km. DeltaFix and RadioLink accuracy is 1-2m. Delta Fix system can be utilized for correction data transmitting with centimeter accuracy. Trimble RTK GPS systems Trimble is the most authoritative company producing GPS equipment. Romona Inc has been utilizing Trimble GPS equipment since 1994. There are a few tens of these receivers in Romona Inc receivers stock. Trimble RTK GPS systems provide centimeter accuracy in real time and can be used during various offshore and onshore operations. Meridian Surveyor, Octans and Orion INS gyrocompasses Gyrocompass Meridian Surveyor is a standard of relative bearing transmitter for offshore surveys. This model is very popular because of its reliability, quality and compact size. True heading determination accuracy of this gyrocompass is 0.1°. Fiber-optic gyrocompass and motion sensor, Octans is known for its robustness, precision and ease of use. As well as being a survey-grade gyrocompass, it provides Roll, Pitch, Surge, Sway, Heave, Speed and Acceleration data, as well as true heading. Basic specifications:
Orion INS has been specifically designed for the demanding hydrographic survey, offshore construction and ROV operations markets. Orion incorporates three single axis ring laser elements and three highly accurate accelerometers. These specific components, widely used in many of the world’s commercial aircraft, were chosen for Orion because of availability, accuracy and their very high meantime between failures. These core elements enabled the TSS research and development team to design this high specification Inertial Navigation System. Orion utilises the latest version of the TSS inertial algorithm which has over 30 years of pedigree providing outstanding performance in all sea conditions. Basic specifications:
TSS DMS 2-05, SMC S-108 è IMU-108 swell compensators Swell compensators measure angular deviation from gravity vector direction in two planes, vertical displacement and velocity of this values alteration. It allows compensation of rolling influence in real time during offshore surveys. Angular values accuracy is 0.1° and heave accuracy is 0.1 m. The DMS 2-05 is designed for a wide range of tasks, from enabling highly productive swath survey from all small launches to providing safety-critical helideck monitoring on FPSO's. The DMS provides accurate motion measurement in all sea conditions incorporating external velocity aiding for additional performance during dynamic maneuvers. DMS provides real time heave, pitch and roll in analogue and digital formats. Key Features:
The IMU-108 is a high performance roll, pitch, heave surge and sway motion sensor, with high angle accuracy during accelerations. Basic specifications:
The equipment can record data on inner storing device ( bottom station ) or in real time ( on vessel or drilling platform). Ice Profiling Sonars (IPS) Ice profiling sonars created by Canadian Company ASL enable measurements of ice cover underwater part thickness. Equipment is installed as a bottom station, which can be fitted with ADCP for ice drift velocity measurement. IPS-4 represents a single beam echo sounder with inbuilt pressure sensor. Ice cover underwater part thickness is detected by measuring distance between transmitter and ice cover lower edge and then it’s subtraction from depth value collected by pressure sensor. DataWell wave meter DataWell (Holland) wave meter enables sea observations (wave height, direction, period measurement). The device is fitted with inbuilt radio transmitter .In combined utilization of receiver it enables heaving observation in real time mode. Vaisala weather station Vaisala weather station enables measuring of basic meteorological parameters such as temperature and humidity, wind speed and direction, atmospheric pressure, amount of solar radiation, amount of precipitation, snow cover height etc. The weather station is equipped with solar batteries which enable operations in offline mode. ROV Seaeye Falcon The Seaeye Falcon is a compact ROV suitable for a variety of observation and inspection tasks. The ROV is particularly suited to rig support eyeball operations were it sets the highest standards due to its exceptional power to weight ratio. Seaeye Falcon features::
Along with above mentioned technique Romona Inc can lease and import required equipment with the shortest possible delay.
