Marbase Lumpfish Hatchery - Saltwater Intake and Discharge Pipelines, Marystown, NL

Marbase Cleanerfish Ltd. is planning to construct and operate a land-based lumpfish hatchery to be located within the Marbase Integrated Aquaculture Service Hub (formerly the Marystown Shipyard) in Marystown, NL. The Marbase Cleanerfish Hatchery will provide lumpfish to Atlantic salmon farming operations where sea lice may be present and act as a stressor to the fish.

 

The proposed project will involve the installation of saltwater intake and discharge pipelines within the public port of Marystown, thus, requiring a Licence to Occupy with Transport Canada, as well as a Canadian Navigable Waters Act (CNWA) approval. The scope of work will involve the following:

 

External to the Hatchery building, a concrete foundation is required for the saltwater pumphouse and storage tank. The detailed routing of the intake piping on the seabed will be confirmed through examination of existing multi-beam acoustic surveys. Pipe sections and ballast will be stockpiled at the Marbase Service Hub dock. A marine contractor will employ a laydown barge to place the pipe and intake along the seabed.

 

The discharge pipe will extend below low water mark, while the intake pipes will extend to water

depths of approximately 15m and 50m. The intakes will have screening to avoid impingement and entrainment of marine organisms. The installed pipes will be ballasted on the seabed. The intakes will be capable of supplying marine water to the hatchery complex on a continuing basis and at two temperatures. The discharge line adjacent to the hatchery will return water following treatment and filtration.

 

The intakes will be located clear of any contaminant sources (sewer and other outfalls, including

the hatchery outfall). The hatchery discharge will be located near surface and proximate to the

hatchery building and at a distance of 500m minimum from other intakes. The pipeline sizing will be established as hatchery design advances.
