Deep Sea Safety Protocols

1. Operational Context

These protocols govern operations at depths exceeding 1,000 meters (3,280 feet). The deepwater environment presents unique challenges, including high hydrostatic pressure, low temperatures, and complex ocean currents. Operations in this domain require specialized equipment, advanced engineering solutions, and strict adherence to procedural checklists to ensure the integrity of the wellbore and the safety of personnel.

2. ROV Operations

Remotely Operated Vehicles (ROVs) are the eyes and hands of deepwater operations. They must be inspected pre-dive according to the IMCA R004 code of practice. Tether management systems (TMS) are critical to prevent entanglement and ensure extended excursion capabilities. All subsea interventions require a specific risk assessment (SRA) approved by the Offshore Installation Manager (OIM) and the Subsea Superintendent.

Dual ROV operations are standard for critical path activities to provide redundancy and simultaneous viewing angles. Real-time video feeds are monitored by subject matter experts onshore to support decision-making.

3. Structural Integrity

Riser margins must be monitored continuously to prevent gas influx in the event of an emergency disconnect. Emergency Disconnect Sequences (EDS) are tested prior to latching the Blowout Preventer (BOP) to the wellhead. We utilize advanced acoustic monitoring systems to detect any subsea anomalies or leaks in the BOP control system. Dynamic Positioning (DP) systems are maintained at Class 3 standards to ensure station-keeping reliability in adverse weather conditions.

4. Personnel Safety

While deepwater operations are largely automated, personnel safety remains paramount. Hyperbaric evacuation plans are in place for saturation diving support vessels. All saturation divers operate under the strict supervision of a Life Support Technician (LST) and follow the US Navy Diving Manual or equivalent international standards. Regular drills are conducted to practice the evacuation of divers in saturation in the event of a vessel emergency.
