Core Responsibilities

Primary Functions

Operate and control dredging equipment (cutter suction dredges, hydraulic pipeline dredges, clamshells, and hopper dredges) to safely and efficiently excavate, transport, and place sediments in accordance with project plans and environmental permits.
Execute daily startup, shutdown and operational checks on pumps, engines, hydraulic systems, winches, spuds, spud winches and anchor systems; diagnose and report abnormal conditions to maintenance and supervisory staff.
Read and interpret project drawings, work orders, hydrographic survey data and dredge plans to plan dredging cuts, depths, and pipeline layout; adjust operations based on survey and site conditions.
Monitor dredge pump performance, slurry density, flow rates and pipeline pressures; tweak pump speed, cutterhead RPM, and suction settings to optimize production and minimize wear.
Maintain accurate operational logs, production reports, hours worked, equipment usage and material disposal records for daily reporting and compliance with contract deliverables.
Coordinate with hydrographic survey teams and GPS systems to verify dredging location, depth tolerances and alignment with project tolerances; execute fine grading and trimming as required.
Perform routine preventative maintenance: lubrication, filter changes, belt and hose inspections, valve adjustments and minor mechanical repairs to ensure continuous dredge availability.
Lead and supervise small deck crews for dredge setup, spud installation, mooring adjustments, pipeline connections and emergency recovery operations while enforcing safe work practices.
Conduct pre-shift safety briefings and job hazard analyses (JHAs); enforce the use of personal protective equipment (PPE), lockout/tagout procedures and confined space entry protocols.
Manage dredge positioning and station-keeping via spuds, anchors or dynamic positioning aids; coordinate with tugs or barges to reposition equipment safely in changing marine conditions.
Install, inspect and maintain floating pipelines, booster pumps, couplings and hose assemblies; oversee dewatering, slurry control and sediment containment systems to prevent spills and turbidity excursions.
Implement turbidity monitoring and silt curtain deployment per environmental compliance plans; stop or adjust operations if monitoring thresholds are exceeded and notify environmental managers.
Respond to mechanical, hydraulic or electrical failures by isolating faults, performing temporary repairs and coordinating with shore-based maintenance teams for complex repairs or parts ordering.
Perform sediment sampling, shoring and placement operations as directed by environmental/specifications teams; ensure disposal locations and beneficial reuse sites conform to permit conditions.
Maintain safe and organized deck spaces: secure gear, rigging and moving parts; ensure proper storage of flammable liquids, spare parts and tools in compliance with safety and environmental regulations.
Execute emergency procedures including spill response, fire suppression, man-overboard recovery and evacuation drills; act as a safety lead on the dredge during incidents.
Communicate continuously with project managers, vessel masters, surveyors, subcontractors and shore personnel to coordinate daily production schedules, resources and logistic needs.
Train and mentor junior operators and deckhands on dredge systems, telemetry controls, safe operating practices and equipment troubleshooting to build team capability and resilience.
Monitor fuel, lube and consumables usage; maintain inventory records and request parts, consumables or vendor services proactively to minimize downtime.
Adhere to all site-specific and regulatory compliance requirements including permit conditions, USCG/Coast Guard requirements, local harbor regulations and company safety management systems.
Operate onboard control systems, PLCs and remote monitoring tools; use diagnostic software to review alarms, trends and performance metrics to support preventive maintenance strategies.
Safely rig and operate auxiliary deck equipment such as cranes, winches, pumps, generators and hydraulic test stands when required by the project scope.
Prepare and submit end-of-shift equipment condition reports, production summaries and any non-conformance or incident reports to project supervision for prompt action.
Conduct root-cause analysis for recurring failures and recommend equipment upgrades, operational changes or training needs to improve availability, production and safety outcomes.

Secondary Functions

Assist marine survey and engineering teams during setup: assist with transducer placement, leadline checks and verification of control points.
Support coordination of material handling logistics for dredged material transport, barging schedules and disposal site acceptance.
Participate in pre-bid site visits and provide technical input on equipment selection, estimated production rates and mobilization planning.
Help prepare scopes for subcontracted services (e.g., pump rental, pipeline fabrication, specialty rigging) and vet vendor capabilities during mobilization planning.
Maintain and update vessel and equipment maintenance databases; support continuous improvement programs to reduce mean time to repair (MTTR).
Assist environmental personnel with permit application data collection, monitoring uploads and corrective action documentation.
Support inventory control by tagging, storing and rotating spare parts and consumables to prevent long lead-time delays during operations.
Contribute to safety committees, incident investigations and toolbox talks; propose procedural updates based on operational learnings.
Aid in diversity and onboarding programs by helping new hires complete operational checklists and hands-on training modules.
Provide backup for mate or onboard supervisors during absences by handling limited supervisory tasks and communications with shore-based management.
