By aligning business goals with ESG priorities, Diving Task Marine Service LTD sets benchmarks for responsible delivery and sustainable growth.
Our Approach & Practices
This policy builds on the inspection framework by integrating specialized guidelines for construction, Inspection, survey, sediment removal, and environmental containment during de-silting operations.
Environmental Practices
-
Silt Curtain Deployment: Mandate the use of geotextile silt curtains around the active de-silting zone to prevent turbid, sediment-heavy water from spreading into surrounding ecosystems.
-
Continuous Turbidity Monitoring: Use real-time underwater sensors during suction dredging to track suspended solids and halt operations immediately if sediment levels exceed local environmental thresholds.
-
Contaminated Sediment Management: Partner with certified onshore facilities to test, handle, and safely dispose of dredged silt containing heavy metals, hydrocarbons, or industrial toxins.
-
Spill Prevention Protocols: Equip all subsea de-silting pumps, survey vessels, and hydraulic tools with food-grade, biodegradable oils to eliminate toxic chemical pollution in case of hose ruptures.
Social Practices
-
Low-Visibility Safety Protocols: Enforce strict tethered diving, audio communication, and live video feeds for divers operating in near-zero visibility caused by stirred-up silt.
-
Entanglement Prevention: Implement mandatory pre-dive inspections to clear debris and map potential hazards, protecting divers from underwater pump intake suction and moving mechanical parts.
-
Public Health Protection: Coordinate closely with local water authorities when de-silting public infrastructure (e.g., reservoirs, water treatment plants) to ensure water supply quality remains uncompromised.
-
Community Disturbance Mitigation: Restrict high-noise dredging operations and heavy vessel movements near residential shoreline areas to approved daytime hours.
Governance Practices
-
Environmental Permitting Compliance: Secure and document all necessary government permits (e.g., Marine Department, Environmental Protection Department) before initiating any sediment removal or disposal.
-
Volumetric Auditing: Maintain transparent, digitally logged records of the exact volume of silt removed, verified against pre- and post-operation.
-
Subcontractor Accountability: Require all third-party barge operators, tug captains, and disposal transport companies to sign and strictly follow your ESG code of conduct.
-
Emergency Response Readiness: Hold documented, regular drills for underwater equipment failures, rapid sediment containment failure, and vessel fuel spills.
