Acadian Seaplants

Acadian Seaplants, a global leader in seaweed processing based in Dartmouth, Nova Scotia, ships crop biostimulants and other seaweed-derived products to over 80 countries. Surging demand for natural biostimulants in agriculture and horticulture required the company to significantly expand its Cornwallis, Nova Scotia facility. Legacy hardwired motor controls made process changes costly and time-consuming — rewiring entire areas was required whenever a production step was added or modified. This rigidity constrained growth and left the company unable to scale output fast enough to meet international order volumes.

Working with electrical supplier Graybar, Acadian Seaplants implemented a Rockwell Automation Integrated Architecture® system centered on Allen-Bradley CompactLogix™ programmable automation controllers (PACs) and CENTERLINE® motor control centers (MCCs) with IntelliCENTER® technology. The entire system was unified over an EtherNet/IP™ network, replacing physical hardwiring with a virtual, software-configurable infrastructure. Three CompactLogix PACs manage all system functions, feeding real-time operational data to on-site HMI displays. Rockwell Software® Studio 5000® provided a single engineering environment for configuring both PACs and MCCs. The EtherNet/IP backbone also enabled remote access for engineers to diagnose and resolve issues without on-site visits. The expansion was executed in stages over three years to maintain continuous production.

The new Deveau Center facility came online in 2014 with zero production downtime during the multi-year transition. Key outcomes include:

• 40% higher production capacity compared to the previous facility from day one
• Scalable to 250% capacity as future demand grows, enabled by the EtherNet/IP-based design
• Reduced hardwiring and maintenance costs through software-configurable motor controls
• Faster issue resolution via remote access, replacing slower on-site visits
• Operators receive automatic HMI alerts for issues, replacing unreliable mechanical indicator lights

The engineering team is now extending the same architecture to other Acadian Seaplants divisions.

• EtherNet/IP-based architectures turn physical wiring into flexible virtual connections, enabling process changes without facility rewiring — critical in complex food processing environments.
• Staged migrations preserve production continuity: Acadian Seaplants moved equipment incrementally over three years without missing a single order.
• Standardizing on a single automation platform (controllers, MCCs, and software) dramatically reduces configuration time and training overhead across facilities.
• Remote monitoring is a force multiplier for lean engineering teams — proactive diagnostics reduce costly on-site interventions.
• Design for future capacity from the start: building headroom for 250% expansion at initial deployment avoids expensive retrofits when demand grows.
