Marine Infrastructure sample projects

Maderra provided project management and multi-disciplinary FEED and detailed engineering for the renovations to the Bull Arm Topsides Construction Yard module loading and transport areas including the pier and quay, for the Hebron project.  The work was completed in conjunction with four partner engineering firms, involves the assessment and remediation of all marine infrastructure including, fenders, bollards, quay wall, and finger pier caisson wall. Maritime International was engaged as fender supplier for this project.  The final marine configuration was able to support all the heavy lift vessels delivering the individual modules in addition to the fully integrated topsides facility which was transported to the deep water site for mating with the GBS.

Davie shipbuilding was awarded a contract to build North America’s first dual-fuel LNG ferries; for the province of Quebec. The two dual-fuel LNG Ro-Pax ferries will operate on the St. Lawrence River on the Tadoussac-Baie-Sainte-Catherine route, due to enter service in 2015.

Maderra was contracted provide engineering services to Davie, with a scope of work that included more than 500 deliverables for the complete ship electrical systems including layout drawings, cable schedules, cable routing, cable transit details, and cable termination details.

Maderra worked closely with Davie and their equipment vendors to coordinate the Electrical work.

​Maderra provided a condition assessment of the transfer bridge beams on the Argentia approach ramp. We performed a visual examination on site and delivered a recommendations report for subsequent action and investigation. The report advised on potential design issues, inspection requirements and repair options.

Maderra Engineering provided engineering services for the wharf infrastructure Electrical systems in Valleyfield, NL. The newly constructed wharf required a new electrical service, complete with new pedestals and associated metering. DFO provided a new building to house the main service. In addition, an adjacent older wharf required metering for its existing pedestals.

Maderra completed an assessment of the four main docks located at North Sydney and Port aux Basques to evaluate fender system replacement options and associated wharf remediation works. The workscope included:  non-destructive visual assessment of fenders and associated structures; evaluation of the dock’s structural components and existing fendering system; crack analysis; engagement of a specialist third-party to deploy an array of measurement equipment to assess the actual behavior of the wharf structure and fender system during ferry docking operations; evaluation of the measurement data with consultative input from fender design specialist; preparation of report including recommendations for replacement of the fendering systems and wharf remediation and upgrade works.

The Port-aux-Basque fabrication module hall was used for the fabrication of the 360 metric tonne, 65 meter long Hebron Flare Boom.  In preparation for the load-out from the module hall, Maderra completed a structural analysis of the quayside and wharf, to ensure that it would safely handle the weight of the module.  

The work included review of geotechnical report covering seafloor under the crib, timber member capacity checks, internal lateral pressure calculations (inside the timber crib), timber crib lateral stability analysis, stability analysis and design of 50 tonne shore and wharf bollards, wharf reinforced concrete slab design, analysis of the connection between the wharf slab and crib, and connection capacity checks.
