Renewable-Clean sample projects

Maderra Engineering completed engineering design, planning, tender administration, and contract administration for the supply and installation of EV Chargers for the Cabox office building.

The hospitals in Gander and Grand Falls-Windsor have oil fired boilers for the generation of steam which is used throughout the hospitals. Maderra Engineering was hired to design the mechanical and electrical systems to convert the oil fired boilers to electric boilers (1.6MW).

The work included interface with the Utility, upgrades to the electrical entrance and distribution systems (12.5kV and 600V), installation of the new electrical boiler systems, electrical distribution, and upgrades to the heating system controls. A Sub-Consultant was engaged to completed the Architectural workscopes.

Maderra Engineering was the Prime Consultant for two projects that covered the removal of Oil Fired Boilers from eight (8) schools in the Avalon region and the design and installation of replacement electric heating systems. The project scope included preliminary design, detailed design, tender support, contract administration, and commissioning support.

The work included interface with the Utility, upgrades to the electrical entrance and distribution systems, decommissioning and removal of the old boilers, installation of the new electrical heating systems, electrical distribution, and upgrades to the heating system controls. Sub-Consultants were engaged to completed the Civil and Architectural workscopes.

Maderra Engineering completed engineering design, planning, tender administration, and contract administration for the supply and installation of EV Chargers for the three Marine Atlantic marine terminals.

The design of the electrical systems for the new Administration Building included the design and integration of a 10kW Solar Panel Array. The Solar Panels are integrated into the electrical system such that the building will consume power generated by the Solar Panel Array as a first priority.

Following the work associated with Marine Atlantic’s GHG Inventory, MAI requested that Maderra develop a Net Zero Roadmap to guide the processes and identify projects that would transition MAI to Net Zero by 2050 or earlier. This included the North Sydney, Port aux Basques, and Argentia terminals as well as Marine Atlantic’s fleet of Vessels.

The Roadmap was an evergreen business tool to identify short and long-term achievable goals established in alignment with Net Zero 2050 Business Targets. The roadmap had a detailed one-year plan which identified opportunities that were identified for easy implementation (low hanging fruit), a semi-detailed 5-year plan, and a long-term plan to achieve sustainable Net Zero operations by 2050. The roadmap incorporated recommendations for business process change, capital projects, maintenance and operational modifications, and a summary of future regulatory changes and emerging technologies that would influence future versions of the roadmap.

The results of the work performed by Maderra allowed Marine Atlantic to increase their Green Marine Certification score in the category of Greenhouses Gases from a score of ‘3’ in 2021, to a maximum score of ‘5’ in 2022.

Marine Atlantic requested that Maderra perform a GHG Inventory for North Sydney, Port aux Basques, and Argentia terminals as well as their fleet of Vessels. This project was to establish a thorough and comprehensive review for each relevant input into Scope 1, Scope 2, and Scope 3 GHG emission contributors and establish a baseline. The data sources to calculate GHG emissions were gathered from within and outside of the MAI organization.

An evaluation was performed to: identify and evaluate applicable regulations including Government of Canada Net Zero Strategy for 2050; identify an IMO Greenhouse Gas Reduction Strategy (2018) to achieve a reduction in carbon intensity of 40% by 2030 compared to the 2008 levels; and complete EEXI (Energy Efficiency Existing Ship Index) calculations.

A validation was conducted of data and deliverables provided by MAI for the Green Marine Program. Business process and maintenance/accounting tracking of data were adjusted to capture data more effectively on a go forward basis.

Input into Annual Business Targets were developed with Senior Leadership and Business Processes were developed to evaluate the potential impact of capital projects against Net Zero opportunities.

Maderra, in partnership with Stress Engineering Services, completed the EPC and Installation of a real-time Subsea fatigue monitoring system. In Phase 1 the system was deployed on the BOP and LMRP of two wells of HSE from the Seadrill West Aquarius. Data was collected over the drilling campaign and in Phase II, the systems were removed and the data was analyzed to determine real versus predicted fatigue life of the risers and subsea components.

Phase I:  Maderra, in partnership with Stress Engineering Services, completed a Study for HMDC with the objective to evaluate the response of the subsea well system from an impact with an object representing a potential iceberg impact. The analysis included identifying the expected mechanical or structural failures, their sequence, the expected weakest point of failure, impairment of mechanical or hydraulic systems which may affect operation of downhole equipment, and any other failure that could potentially cause a loss of containment.

Phase II:  This follow-on phase included a more detailed model of the subsea equipment and the 3D model of an iceberg. The objective of this Phase was to evaluate the response of the specific subsea well system from an impact with an iceberg. As with phase I, the analysis included identifying the expected mechanical or structural failures, their sequence, the expected weakest point of failure, impairment of mechanical or hydraulic systems which may affect operation of downhole equipment, and any other failure that could potentially cause a loss of containment. In addition, the results were evaluated to identify mitigation measures that could be implemented to any part of the subsea well system.

Maderra has entered into a multi-year service agreement to provide Engineering, Project Management and Personnel to support the development of offshore wind projects in Atlantic Canada.
