Our projects are approached in a detailed, considered manner. We combine our considerable technical experience and project management skills to ensure all stages of our projects are delivered successfully so that the final data delivered to our clients are fit for purpose. These projects are just a few of the +170 that OSL has completed.
Cluster 37 Conductor Pile Positioning
Real time Barge Navigation, Conductor / Pile positioning, Sub-Sea Template positioning support and final As-Built Survey
-
Location
Soldado East Field, Gulf of Paria, Trinidad
Date executed
July 2024
Client
Veratech Engineering and Construction Company Limited (VECCL)

For this project, OSL mobilized a survey team of two (2) surveyors to the Ignacio Grande Crane Barge who then installed the requisite navigation systems for real-time positioning. OSL’s team performed dockside calibrations of positioning and heading sensors which established precise operational parameters and also developed comprehensive survey procedures that earned client approval.
Once on-site, OSL’s surveyors provided accurate positioning support for Cluster 37 conductor placement throughout the piling operations. The team successfully collaborated with third-party ROV contractors for subsea template positioning, demonstrating seamless integration with project partners.
Following completion, OSL conducted a thorough As-Built survey before demobilization. The project concluded with a detailed survey report documenting all phases; from mobilization and calibration through field execution, delivered safely under the oversight of construction engineers and client representatives.
Following each survey, volume computations were meticulously performed, with dredge volume analysis and forecasts becoming an iterative process from the second survey forward. OSL’s operations flowed seamlessly around the port’s busy shipping schedule, ensuring no disruption to client activities.
The project faced initial challenges when two immobile derelict drilling rigs hindered vessel access. Undeterred, the team innovatively mapped perimeters and areas beneath the rigs using special sonar settings and precise close passes, then interpolated remaining data gaps to achieve complete volume calculations. The project culminated in comprehensive final reporting and detailed tidal data analysis.
Hydrographic Surveys at the Port of Brighton
Multibeam Hydrographic Surveys, Tidal data collection and analysis along with Land Surveys for survey control establishment on site.
-
Location
Port of Brighton, La Brea, Trinidad
Date executed
Contract executed in September 2023, project scheduled for a duration of 18 months
Client
La Brea Industrial Development Company (LABIDCO)

OSL embarked on a comprehensive surveying project, executing five multibeam surveys of the channel and turning basin at strategic intervals. Each survey was delivered on schedule without safety incidents. Recognizing the dynamic site conditions and geomorphological concerns, the team implemented additional positioning checks and level loops to monitor potential deformation throughout the project duration.
Following each survey, volume computations were meticulously performed, with dredge volume analysis and forecasts becoming an iterative process from the second survey forward. OSL’s operations flowed seamlessly around the port’s busy shipping schedule, ensuring no disruption to client activities.
