Built for Harsh Marine Environments
Sustainable Operational and Environmental Benefits
From coastal operations to global fleets, SPOC delivers energy-efficient marine power systems engineered to withstand demanding duty cycles and harsh operating conditions. Our systems help vessel owners burn less fuel, lower operating expenses, and run generators at optimal load profiles while reducing emissions without sacrificing uptime. By extending generator and equipment life and maintaining predictable performance across operating modes, SPOC delivers measurable efficiency—not theoretical gains.
Purpose-Built Power Solutions
Drives for Pumps & Motors
SPOC has 25 years of experience building Variable Frequency Drive packages—with over 80,000 units installed in the harshest environments. Offering a full range of sizes from <1kW to 4 MW and voltages of 480, 690 VAC and up to 1100 VDC, we provide complete plug-and-play solutions including power electronics, circuit protection, and enclosures—as well as active and passive IEEE 519 compliant harmonic solutions. SPOC provides industry-leading 24/7 support and on-site service. Upgrade your power system to reduce inrush currents, minimize mechanical stress, and optimize your power usage and efficiency.
Purpose-Built Power Solutions
Multi-Drive Systems and Lineups
SPOC engineers, manufactures, and services inverter-based marine power systems—providing you with purpose-built systems for the most demanding applications. Whether it’s for the power distribution system on a new build or retrofitting batteries to an existing vessel or VFD packages for all your auxiliary loads—SPOC has the solutions you need. We supply inverters, filters, chokes, circuit protection as well as custom enclosures and complete liquid cooling systems including chillers. Contact us to talk to an expert in adopting energy storage or advanced next-generation DC bus configurations to enhance redundancy, reliability, and efficiency. SPOC understands the critical nature of the marine industry and offers 24/7 service and support to our valued clients.
