Seaforth completes cable route survey landings off Newfoundland

Survey completed despite ice

Seaforth Engineering Group Inc. completed several cable route landing surveys along the south coast of Newfoundland, Canada. The work is in fulfillment of an earlier contract awarded to Seaforth by International Telecom.

The survey was several weeks in duration and involved the mobilization and execution of an integrated survey operation in harsh ice infested waters.

Seaforth subcontracted the services of Edwards and Associates, St. Lawrence, Newfoundland. The team mobilized a 22 foot survey launch with differential GPS, Klein 3000 sidescan sonar, and a Singlebeam echosounder. Shorelining for landing sites was conducted using GPS RTK technology.

The landings proved quite challenging for the Seaforth team as weather in Newfoundland can be rather chilly and wet at this time of year. Sea states are also challenging and extra emphasis was placed on safety and equipment care and operation. In the end, all the required work was completed with marginal down time attributed to weather.

Survey work was also conducted on several Nova Scotia landing sites including the Canso Causeway.
