Services
Coastal Engineering
Our coastal engineering services address beach erosion, storm inundation, and sea level rise challenges. We provide harbor planning, fiber optic cable routing, and coastal structure design for both private and government clients. With 50 years of experience, our engineers combine numerical modeling with field data to create sustainable solutions that balance environmental protection with infrastructure needs.
Hydrographic Surveys
We conduct high-resolution bathymetric surveys using multibeam sonar and subbottom profilers. Our services include pipeline route selection, magnetic anomaly detection, and sand deposit investigations. With global experience from Madagascar to Samoa, we deploy state-of-the-art equipment for accurate seafloor imaging and navigation planning in challenging marine environments.
Underwater Inspection
Since the 1990s, we've inspected offshore facilities including oil moorings, bridges, and pipelines. Our services combine ADC-certified divers with advanced technologies like ROVs and ultrasonic testing. We adhere to ASCE and U.S. Army Corps standards, providing detailed assessments for clients including the U.S. Navy and major port authorities across the Pacific.
Commercial Diving
Our commercial diving services since 1986 include underwater welding, pipeline installation, and marine demolition. With 30+ years experienced supervisors and a fleet of support vessels, we offer 24/7 services meeting EM385-1-1 standards. Our NDT-trained divers perform inspections and repairs for energy infrastructure and maritime facilities across the Pacific region.
Offshore Renewable Energy
We support wave and tidal energy projects through site assessment and infrastructure installation. Our services include ocean current measurement and offshore wind planning. We engineered Hawaii's Marine Corps Base Wave Energy Test Site, combining marine construction expertise with renewable energy system deployment for sustainable power generation in coastal environments.
