INTECSEA Canada has been awarded a contract by Petroleum Research Atlantic Canada (PRAC) for Phase 1 of a Joint Industry Project (JIP) for the Development of a Trenching System for Subsea Pipelines, Flowlines and Umbilicals in Ice Scour Environments.
The trenching system will be relevant to Arctic and Subarctic waters wherever ice gouging is an issue. INTECSEA will be responsible for the management of Phase 1 of the JIP and the provision of consulting services to support the program. The JIP is sponsored by the Hibernia, Terra Nova, White Rose and Hebron Projects.
The goals of the new trenching system will be a system which is capable of:
- trenching to depths greater than current industry norms (burial depths greater than three metres, with potential trench depths as much as seven metres);
- trenching in soil conditions that are difficult and highly variable, including the presence of boulders; c) trenching in water depths beyond the majority of trenching requirements (water depths up to approximately 300 metres); and
- operating in harsh marine conditions (for example, the Western North Atlantic).
The JIP is planned to be a research and technology development project with four phases. The objective of the project is to prove a trenching system that is capable of meeting the above requirements and concluding with a full scale field demonstration project in Phase 4. The goal of Phase 1 is to shortlist a number of potential technology solution providers who will carry out more detailed engineering and feasibility studies in Phase 2.
The work will be performed at INTECSEA's office in St. John's, Newfoundland and Labrador. "This is a great opportunity for INTECSEA Canada and we will draw upon the experience that we have gained over the past 25 years designing Arctic and cold region pipelines," said Mike Paulin, Operations Director of INTECSEA Canada. "This is an important step forward in the ability to safely and efficiently install pipelines and flowlines in ice scour environments."
"This puts INTECSEA at the centre of this industry effort to improve the cost and decrease the risk of deep trenching in challenging environments with highly variable seabed conditions – understanding of the different drivers of development stakeholders, trenching contractors and trenching technology vendors will be a crucial aspect," said INTECSEA's Senior Vice-President and Chief Technology Officer, Garry Mahoney.
