Dimensional Control Surveyor

Main tasks and responsibilities include: • Risk assessments and the safe conduct of survey work within constructions yards, vessel dry-docks, quaysides, offshore platforms/structures, and onboard vessels. • Setting out of local grids around structures to be surveyed with sufficient redundancy to allow grid coordinates to be computed, adjusted, and checked with suitable quality indicators. • Establishment of absolute survey control by observation and processing of dual frequency GPS carrier phase observations on site and processing of data from remote GPS control stations such as IGS stations or local government stations. • Calibrations of surface positioning sensors such as gyrocompasses, pitch and roll sensors based on dimensional control survey results and absolute survey control
