Offshore Surveyor

Position Overview

The Offshore Surveyor is responsible for the acquisition, processing, and quality control of hydrographic, geophysical, and positioning data during offshore survey operations supporting pipeline installation, subsea construction, site investigation, and field development campaigns. This role provides the spatial data foundation upon which all offshore engineering and operations depend.

Key Responsibilities

• Acquire and process offshore survey data including multibeam echosounder, side-scan sonar, sub-bottom profiler, and magnetometer data
• Operate and maintain offshore positioning systems (USBL, LBL, DGPS) for vessel and ROV tracking during construction and installation operations
• Perform real-time quality control of survey data to ensure compliance with project specifications and IHO standards
• Process and interpret geophysical survey data for route surveys, site surveys, and as-laid/as-built surveys
• Prepare survey deliverables including bathymetric charts, seabed feature maps, route position lists, and survey reports
• Calibrate and test survey sensors and positioning systems prior to and during offshore operations
• Provide survey support during pipelay, cable lay, and subsea installation operations including touch-down monitoring
• Coordinate with ROV teams, vessel bridge, and project teams on survey requirements and operational sequencing
• Maintain survey equipment inventories, calibration records, and maintenance logs
• Ensure survey operations comply with client specifications, regulatory requirements, and industry best practices

Qualifications

Required

• Education: Bachelor's degree in Geomatics, Hydrography, Surveying, Geophysics, or related field
• Certifications: BOSIET/FOET; Valid Offshore Medical; Cat A or Cat B Hydrographic Surveyor certification preferred; IMCA or equivalent survey competence scheme
• Experience: Minimum 3 years as offshore surveyor on construction, pipelay, or geophysical survey campaigns
• Technical Skills: Multibeam and side-scan sonar operation; USBL/LBL positioning systems; survey data processing (QINSy, Hypack, Caris); geophysical data interpretation; tidal and sound velocity corrections

Preferred

• Experience on pipelay and cable lay survey support operations
• Advanced geophysical data processing and interpretation skills
• AUV survey operations experience
• Offshore wind pre-construction survey experience
