Ongoing Aquatic Habitat Restoration & Ocean Floor Cleanup

Environmental cleanup around remote beacon lights

This ongoing project spans the entire BC coast, regularly presenting challenges to our commercial dive team in remote marine environments, strong currents, and adverse weather conditions.

Historically, marine navigation beacons used energy sources that, upon reaching the end of their usefulness, were no longer needed. However, these spent energy sources sometimes ended up in the ocean, resulting in them settling on the ocean floor near these remote beacons. Our divers meticulously search the area around navigation beacons, often in challenging conditions, as part of an environmental cleanup effort.

When an energy source is found, it is safely extracted and brought back to land for appropriate disposal. Additionally, sediment and water samples are collected from the recovery site and processed aboard our purpose-built dive boat. Data is carefully gathered and stored for future analysis. Video recordings are also taken and reviewed at SeaVeyors headquarters by our in-house Environmental Assessment Biologist.

The initial phase of this project took us to Tofino on the west coast of Vancouver Island, as well as north to the Kitimat and Prince Rupert areas, with a four-person dive team and representatives from the BC government and our client. Our team eagerly anticipates continuing this important environmental cleanup work, contributing to the preservation of our BC coastline, one energy source at a time.

Anchoring Inspection & Marine Repairs at Ḵ̓wax̱wa̱lawadi

Ḵ̓wax̱wa̱lawadi, Echo Bay Marina & Lodge

When this historic site on the BC coast was purchased by new owners, we initially engaged with them to conduct an anchor survey and supply a simple location diagram. However, it quickly became apparent that these new owners needed more help.

The famous, floating Echo Bay Lodge needed new floatation supports in some spots, and had old structures that needed to be removed for safety concerns, in addition to needing an entirely new anchoring system. The new owners were slightly overwhelmed by the scope of the work needing to be done, and they didn’t have the staff on hand to help coordinate this project on top of the day-to-day running of the Lodge. Our team jumped into action to provide the additional support that was needed.

We came up with a plan to coordinate with a crew we already had in the area on another job, and offset client costs by sharing their accommodations. In addition, we linked in with an aquaculture client who helped us bring in a large crane to assist with anchor placement, which sped up the job considerably.

Overall, this project took over a month to complete with a two-person crew, the results being new floatation supports added, two old and damaged piers removed, and the lodge securely anchored and correctly placed. By utilizing resources already at hand, we were able to keep disruption to the Echo Bay community to a minimum while keeping costs as low as possible for the new owners.

Ocean Floor Clean-ups & Aquatic Habitation Restoration Projects

Decommissioned Aquaculture Sites: Ocean floor clean-up

When an aquaculture site is decommissioned, it is a requirement that they engage with a contractor to provide underwater clean-up services at the site. Our team has been heavily involved in multiple projects of this kind, and we are one of the most experienced underwater clean-up crews on the coast.

In addition, we are committed to working with First Nations in whose territory we are operating, which often means that First Nation guardians or observers become a part of our team on these projects.

Clean-up jobs begin with a detailed plan that outlines crew size, equipment needed, conditions both underwater and above water of the site, client expectations and data collection. Some of these variables won’t be known until after we conduct a preliminary survey.

Factors such as site depth play a major role in these projects – many aquaculture sites are located in waters that are too deep to be safe for our divers. This is when our ROV fleet becomes indispensable.

The purpose of the preliminary survey is to first gauge how many items need to be recovered from the ocean floor and second, what those items are. Heavy weight blocks are more challenging to recover back to the surface than netting or lighter debris – conducting a preliminary survey allows us to let the client know exactly how long the clean-up will take, how many items we expect to recover, and whether we may need additional supports, such as a crane barge, throughout the operation.

Underwater clean-ups are usually a multi-week or multi-month project, and can utilize more than one vessel and ROV unit at a time. We are proud of our ability to execute these jobs in a timely fashion, helping to restore ocean environments to their natural state.

Marine Survey & Dock Construction Project

New dock installation: Dual-environmental survey

In the scenic Sunshine Coast of British Columbia, near Earl’s Cove, we recently concluded a comprehensive dual-environmental survey for a private residence embarking on a new dock installation. These surveys play a pivotal role for both businesses and private individuals seeking permits and approvals for dock or moorage construction projects.

Our latest endeavour featured the utilization of cutting-edge technology, including our Seabotix ROV and our custom-built SeaVeyor IV vessel. The survey involved conducting underwater transects at 10-meter intervals across the proposed dock site, spanning from deep waters to the shoreline. Each transect was meticulously recorded digitally for subsequent analysis. Additionally, our team captured terrestrial photographs and conducted a thorough riparian survey, all completed efficiently within a single day.

With our expertise and advanced equipment, we ensure precise and expedited assessments to facilitate the permitting process for dock installations and similar projects along the beautiful coastline of British Columbia.
