About geophysical, geotechnical and marine surveys
Geophysical surveys measure physical properties to interpret subsurface conditions. Geotechnical investigations assess ground characteristics, while marine surveys describe selected underwater or seabed features. Each requires a defined study objective.
Where the service is used
Exploration and infrastructure projects use survey information for planning and design. Site conditions and required resolution influence the methods.
Service options and scope
Specify area, methods, data formats and interpretation deliverables. Access, permits and mobilization responsibilities should be clear.
Survey area and objective
A clear scope describes the intended result and the responsibilities of the parties involved. List the required deliverables and identify which design or operating decisions have already been made. Separate investigation, engineering, supply, installation and acceptance activities where they are different work packages. State the review process and the information that will be provided by the buyer or operator. This allows proposals to address the same work and makes omissions or additional services visible before a commitment is made.
Required resolution and methods
The required evidence should relate to the actual purpose of the item or assignment. Identify the method, acceptance basis and documents required by the project, including the relevant edition or revision where specified. A certificate title alone may not establish that the required scope or measurement range is covered. Distinguish manufacturer records, calibration results, inspection reports and specialist qualifications. State whether witnessing or independent review is required, and make the responsibility for evaluating the results clear before comparing technical and commercial proposals.
Site conditions and access
The work location and installation conditions affect access, equipment arrangement and the resources needed to complete the scope. Include known restrictions, available utilities and interfaces with existing operations. For a service, identify what the site provides and what the contractor must mobilize. For equipment, record space, handling and connection constraints that could affect installation or maintenance. If a survey is still required, distinguish confirmed information from assumptions so that the proposal can identify the conditions on which its price and programme depend.
Data formats and deliverables
Functional and digital interfaces determine how the requirement connects to the existing system. Identify the installed platform, relevant versions and required signals or data formats. Separate hardware compatibility from software entitlement and engineering work; an available connection does not establish that the complete function is included. Document ownership of configuration, integration and acceptance testing. Share interface requirements through appropriate project documents without disclosing passwords, activation keys or other account credentials. This makes the proposed scope easier to assess and reduces ambiguity during implementation.
How related requirements differ
Advanced NDT and corrosion mapping: Advanced non-destructive testing uses selected measurement methods to examine specified material or equipment conditions. Corrosion mapping records thickness or related information across an agreed area to support integrity assessment. Method, coverage, access and acceptance criteria distinguish service scopes. Raw data, interpretation and reporting requirements should be explicit.
Risk based inspection and fitness assessment: Risk-based inspection evaluates inspection priorities using asset and damage information. Fitness assessment considers whether an identified condition meets a defined engineering acceptance basis. These studies have different objectives and inputs. Specify assets, methods, study boundaries and deliverables. Inspection acquisition and engineering assessment may be separate scopes.
Pipeline inline inspection services: Inline inspection services use instrumented tools travelling through a pipeline to collect data about specified conditions. Tool selection and interpretation depend on the line's configuration and target defect types. Define detection targets, validation requirements and data deliverables. Cleaning, operational support and engineering assessment should be identified separately.
Compare the complete service proposal
For geophysical, geotechnical and marine surveys, compare the stated work, personnel, equipment and deliverables before comparing the headline price. A proposal may exclude preparation, access equipment, consumables, standby time or completion documentation. Identify these boundaries in the same way for each offer. The project location and work window should be explicit, together with the required qualifications for the particular assignment. Oillinko receives the enquiry and coordinates clarification with you; the actual service arrangement and the suitability of the proposed specialist are reviewed for the project.
Questions before requesting a quotation
What information should be available first? Start with the intended application and the current technical specification for geophysical, geotechnical and marine surveys. In this category, the initial review includes survey area and objective, required resolution and methods, site conditions and access, data formats and deliverables. Attach the relevant drawings or scope documents and identify any information still awaiting confirmation. This makes it possible to distinguish a preliminary enquiry from a fully defined purchasing or service requirement.
Does a service listing confirm that a contractor is already appointed? No. The listing describes a scope that can be submitted to Oillinko for review. The proposed specialist, location coverage, qualifications, work boundaries and commercial terms are checked for the actual enquiry. Equipment rental, personnel and complete execution should not be assumed to be included together unless the proposal expressly states that scope.
