GEOTECHNICAL ENGINEERING SERVICES
GEODESY SURVEYING
The Vision Group is able to provide Geodesists and Surveyors to ensure complete positioning control onshore and offshore. Our surveying and positioning consultants are experienced in land, marine and transition zone 2D and 3D seismic; pipelaying and pre- and post- route studies; rig moves; ROV and SSCV operations and many other disciplines.
GEOTECHNICAL ENGINEERING PROJECT MANAGEMENT
Within the offshore services that The Vision Group offers are many highly qualified consultants specifically targeted at the Geotechnical Engineering disciplines. Although many of the tasks within this category can be presumed related to the offshore survey services our consultant disciplines also encompass the following:
- Project Studies and Design
- Construction Project Management
- Pipeline Engineering
- Structural Engineering
- Environmental Impact Studies
- Geophysical and Geological evaluations
ENGINEERING SURVEY SERVICES
The Vision Group provides services to the offshore engineering and construction industry. The following examples of offshore survey services complement the existing services but may be managed autonomously:
- Hydrographic surveys utilizing single and multi-beam sources
- High-resolution analog and digital site surveys
- Dredging surveys
- MOD (N) or NOAA nautical chart upgrade surveys
- Environmental remediation site analysis
- Pre- and post- pipeline surveys
- Right-of-way/route surveys
- Search and recovery operations
- ROV and RCV operations
- Cathodic protection services
- Gravity and/or magnetic surveys
- Oceanographic studies
The objectives for many high resolution and construction and engineering surveys would generally take the form of:
- Defining the water depths across the site and reducing them to a stated vertical datum, ordinarily MSL (Mean Sea Level) or LAT (Lowest Astronomical Tide) and establish a seabed gradient.
- Identifying any seabed features and obstructions.
- Identifying the seabed lithology and structures such as faulting, unconformities, channeling and sand waves.
- Identifying any surveying or drilling hazards such as shallow gas pockets close to the seabed.
- Identifying pipe laying, trenching, drilling, anchoring and/or leg penetration constraints, such as boulders at the seabed or within the shallow geology.
- Recording the environmental, tidal and current conditions for the area.
- Other services, such as the planning of engineering and/or construction site surveys, area scouting trips or pre-seismic shoot area analyses can also be offered.
DRILLING ENGINEERS WELL-SITE GEOLOGISTS
With the increased drilling activity world-wide, The Vision Group has recognized a requirement to provide specialists particularly for these operations. To enhance a clients’ drilling program and enable on-site evaluation of structural and sedimentary analysis our engineers and geologists would form part of the team on the drilling operation on- and off-shore.
HEALTH, SAFETY AND ENVIRONMENT
Any company within the oil- and gas-related exploration field today, whether it is a vessel charter company, an oil company, a contractor or a consulting firm, needs to have an understanding (or increased awareness) of how safety and environmental planning has to be a major factor in overall business strategy. An awareness of safety issues and a respect for the environment are the two most fundamental concepts of modern day survey programs. Lack of awareness can lead to heavy costs, ultimately leading to a real reduction in the bottom line.
The Vision Group offers qualified, experienced personnel who can assist or take a major role in the development of effective safety programs and environmental management programs. Services provided include:
- Development of safety plans and guidelines
- Pre- and post-survey inspections
- System and equipment audits
- Operations’ cost evaluations
- Risk Analysis and site assessment
- Audits of Hazmat storage and handling
