Deepwater Subsea Supervisor

The supervisor assesses marine geotechnical survey data, including cone penetration test CPT resistance, seabed shear strength, and grain size distributions to configure trenching plow shares and high pressure fluidization water jets. They regulate tow wire pull tension, which can exceed two hundred tons on massive fifty ton seabed plows, adjusting tow angles and speed to cut clean continuous trenches up to three meters deep into hard clays and sands without snapping or over tensioning the delicate fiber optic or high voltage cable passing through the plow share guide chute.

While computer telemetry displays plow attitude, share depth, and tow tension in real time, underwater seabed trenching takes place entirely out of direct human sight in unforgiving ocean conditions. Hidden glacial erratic boulders, rocky seabed outcrops, and submarine slopes can suddenly jam the plow, creating lethal tow wire snap back hazards on deck. The supervisor coordinates deck winch drivers, dynamic positioning operators, and subsea acoustic beacon trackers, executing immediate plow lift maneuvers, deploying tracked water jetting ROVs for backfill verification, and guaranteeing depth of lowering DOL compliance.

The morning begins in the cable ship operations room, reviewing seabed side scan sonar records and cone penetration test results for the next twenty nautical miles of transoceanic fiber optic cable route. The supervisor monitors the continuous tow of a forty ton subsea plow moving at one knot, watching load cells holding steady at eighty tons of pulling force in stiff marine clay. They cross reference plow pitch and roll angles, confirming that the cable is feeding cleanly through the internal bellmouth and into the trench at a verified two point five meter burial depth. At midday, a sudden spike in tow line tension flags a subsurface boulder field. The supervisor immediately orders the vessel to pause tow pull, commands the plow hydraulics to lift the share, and maneuvers the ship along a five degree offset to clear the obstruction. The day wraps up by reviewing post lay inspection sonar logs from the survey ROV and certifying the completed burial segment.

In the afternoon, you execute core deliverables, consult with cross functional colleagues, document operational outcomes, and ensure that all equipment and handover notes are fully updated before completing the shift.

A Deepwater Subsea Cable Plow Trenching and Jetting Supervisor directs, oversees, and manages subsea seabed trenching, cable burial, and post lay inspection operations to protect transoceanic fiber optic communication lines and offshore wind power export cables from ship anchors, fishing trawler gear, and subsea landslides. Operating aboard specialized heavy cable laying vessels and trenching support ships, the supervisor commands heavy subsea seabed plows and high pressure tracked jetting trenchers.

Core responsibilities include supervise subsea cable trenching operations using heavy seabed plows and tracked water jetting machines., operational coordination, and ensuring strict adherence to Kenyan statutory frameworks and quality standards.

Key organizations hiring for this role include Kenya Ports Authority KPA Marine Operations, Kenya Maritime Authority KMA, Kenya Pipeline Company KPC Offshore Terminal, Kenya Coast Guard Service, alongside expanding opportunities in Nairobi, Mombasa, Kisumu, and regional infrastructure projects.
