UNIQUE SURVEY SERVICES

HYDROGRAPHIC SURVEYS

A Comprehensive array of survey sensors and trained Personnel are mobilized on vessels to obtain detailed information of seabed and sub-seabed condition. The assessment of the seabed and sub-seabed are critical to the Cost effective design of Marine Structure and Sub-sea installation. These surveys provide data required for essential engineering analysis of offshore structures.

We are able to mobilize the spread at short notice to monitor construction project during all steps of work progress such as prior, during and after installation are as follows:


  • Pre-Engineering Survey (Pipeline, Subsea structure, Fiber Optic Cable, Power Cable, Subsea Structure of SPM, SBM, PLEM, Jacket piling, Wind Farm, Jetty, Harbour etc)
  • Pre-Installation (Pre-Lay) Survey (Pipeline , Subsea structure, Fiber Optic Cable and Power Cable, Subsea structure SPM, SBM, PLEM, Jacket piling, Wind Farm, Jetty, Harbour etc)
  • Post Installation (As-Laid or As-Built) Survey (Pipeline , Subsea structure, Fiber Optic Cable and Power Cable, Subsea structure SPM, SBM, PLEM, Jacket piling, Wind Farm, Jetty, Harbour etc)
  •  Anchor Clearance (Hazard) Survey prior installation Temporary or permanent 
  • Hydrography (Seabed Mapping) Survey.
  • UXO Survey.

DIMENSIONAL CONTROL SURVEY SERVICES

Dimensional Control and monitoring services, utilizing proven engineering survey techniques and modern survey equipment, can provide substantial benefits to any project both onshore and offshore.

The field data is gathered utilizing an Electronic Laser/Infrared Total Station capable of measuring distances to +/- 1mm (1/24”) accuracy. The total station can be tripod mounted or attached to structural elements within the facility in many configurations allowing easy movement through even the most congested of areas without loss of accuracy. In addition to the information gathered via the Total Station, we can also capture and merge field data using our survey grade GPS units. The data collected from each dimensional control survey is imported into DIMES (Data Integrated Management Engineering System) This software and methodology solution allows the surveyor to move around the plant/platform using multiple survey instrument setups referencing to a “common reference point system”. At completion, all setups are tied together using 3D network calculation software that creates a single, highly accurate coordinate network file. The system has interrogation tools and translation/ rotation functions to “best-fit” the measured coordinates to the plant/platform reference system. At a later stage this is utilized for semi-automatic CAD drawing routines. One of the main benefits in adopting DIMES is the eradication of on-site hot work (welding, grinding, etc.) ensuring that the associated safety risks to personnel are minimized. In addition, this technology also serves as a backbone to delivery of successful laser scanning projects.


DATA PROCESSING AND CHARTING

Hydrographic Mapping – Navigational charts require data of the highest quality. The Blue Ocean Hydrography Services (FZE) has innovative and robust data acquisition, processing personnel and methodologies to deliver data of exceptional quality in all water depths from the shoreline.

The Blue Ocean Hydrography Services (FZE) bathymetric charts to the following international standards:


  • IHO S44
  • IHO S57
  • General Instructions for Hydrographic Surveys (GIHS)
  • GIS deliverables to OGP/IMCA Seabed Survey Data Model (SSDM) or client’s specific geo-database schematic formats.

MARINE CONSTRUCTION SURVEYS

We offer construction surveys/support to our clients to allow the safe installation of offshore assets. These activities depend upon precise surface and subsea positioning data and accurate data regarding surface and subsurface assets.

The Blue Ocean Hydrography Services (FZE) is vastly experienced at performing construction support services for our clients and can help to complete a project on time, in budget and with safe operations.

During construction, support activities such as pipe lay and jacket installation, we can provide a Tug Management System (TMS) on our client’s barges. The system is mobilised onto anchor handling vessels allowing the vessel position, speed and direction to be monitored from the main barge or rig during the activity. Commands for anchor deployment and recovery are also relayed through this system.

We provide a comprehensive range of positioning and construction support services for the following activities:


  • Survey support during pipe-lay
  • Survey support during PLEM installationsUNIQUE STYLES
  • Survey support during SPM installations
  • Survey support during hook-up work

DREDGING SURVEYS

The Blue Ocean Hydrography Services (FZE) activities have provided comprehensive experience of the wide variety of dredging methods and types and sizes of dredging equipment. BOH also has experience of the survey equipment and methods used for monitoring and controlling dredging, as well as for the determination of volumetric quantities. We utilise state-of-the art numerical modelling software, which is commercially available.

Our expertise in this field includes:

  • Design, specification and supervision of dredging
  • Dredging methods and equipment
  • Navigation studies and maritime risk assessment
  • Siltation studies

POSITIONING SURVEYS
