✓ Proven Safety Record
Our commitment to health, safety, and environmental stewardship is reflected in our COR certification and excellent standing with WorkSafeBC. We implement customized Dive Safety Plans and Emergency Response Plans (ERPs) for every project.
✓ Turnkey Project Delivery
From inspection and reporting to construction support and final repair, we offer full lifecycle solutions. Our in-house dive teams work seamlessly with engineering consultants, municipalities, and contractors to meet even the most complex project needs.

Our mobile teams and vessel-based capabilities allow us to serve clients quickly, even in remote or coastal regions of the province, such as the Gulf Islands, Haida Gwaii, or the Columbia Basin.

Our Approach: Safe, Efficient, Transparent
Every commercial diving project we undertake begins with a comprehensive Dive Safety Plan and Job Hazard Assessment. This includes the identification of all potential site-specific hazards, controls, and communication procedures. We always operate with a minimum 4-person CSA surface-supplied dive team and deploy additional staff as needed for support, safety, and redundancy.
All dive operations are logged, recorded with 2-way communication, and documented with either high-resolution video or written inspection reports. Where required, we supplement our dive inspections with sonar mapping, ROV visuals, or UT readings.
