What CATC does

CATC (Control at Sea) is a privately held Swedish engineering firm, founded in 2011 and headquartered in Gothenburg, that delivers turn-key HVAC automation systems and refits for marine vessels. Its primary customers are cruise lines (Carnival Corporation, AIDA Cruises, Color Line, Gotland Shipping), ferry operators (Stena Line, DFDS Seaways, Viking Line), shipping companies (Wallenius), and offshore accommodation providers (Floatel). The company's core technology is the proprietary ViewPort HVAC Supervision System, a PC-based control and monitoring platform that provides a simplified operator interface for complex shipboard HVAC plants, supplemented by in-house source-code generation tools that auto-produce PLC code, IO assignments, functional descriptions, SCADA visualizations, and CAD drawings from terminal to dialog. CATC also supplies refurbished ABB AC31 PLCs, marine electrical spare parts, and ventilation mechanical components as an aftermarket offering.

The business model is project-based enterprise sales: CATC takes on electrical design, PLC programming, project management, installation (via its own team of ship electricians), commissioning, and service, delivering all material that makes up an automation plant for both new builds and retrofits. Pricing is custom, quote-based, and structured around multi-year engagement cycles aligned with vessel dry-dock schedules. The firm employs 8 people and is fluent across multiple PLC platforms (Wago, Beckhoff, Schneider, ABB) and SCADA systems (Wonderware, Intellution), with documented system integrations into Halton MARVEL, Valmet, Crestron, and Emerson fuel meters. Its value proposition centers on demonstrable fuel and energy savings — quantified customer outcomes include 2.4 tonnes of fuel saved daily on DFDS Pearl Seaways, 5,000 kWh daily savings on DFDS King/Princess Seaways, and ~260 MWh monthly energy reduction on Viking Glory — positioning CATC in the marine decarbonization and energy-efficiency segment. In 2025, the company was recognized as a Di Gasell Company by Dagens industri for sustained strong growth.

Broad incumbents

• ABB Marine & Ports: ABB's marine division provides automation, drives, and electrical systems for vessels, including HVAC and energy management. CATC explicitly programs ABB PLCs and supplies ABB frequency drives, making ABB both a technology partner and a potential competitor on integrated vessel solutions.
• Kongsberg Maritime: Norwegian supplier of ship automation, control, and energy management systems, including HVAC and machinery automation. Overlaps with CATC's marine control scope but serves a much wider customer base with integrated bridge-to-engine-room solutions.
• Rockwell Automation: Large industrial automation vendor with marine-adjacent offerings in PLC, SCADA, and energy management. Comparable to CATC as a control platform supplier, but at vastly greater scale and breadth.
• Schneider Electric (Marine): Global industrial automation major whose PLCs and EcoStruxure platform are explicitly supported by CATC. Competes indirectly via integrated vessel automation offerings and direct HVAC control products for marine and industrial buildings.
• Wärtsilä: Large Finnish marine technology company offering integrated automation, navigation, and energy management systems for ships. Competes with CATC in vessel HVAC and energy optimization at the fleet/newbuild level, though as part of a much broader portfolio.

Direct peers

• Praxis Automation Technology: Dutch supplier of marine automation, alarm monitoring, and HVAC control systems for commercial shipping and offshore. Directly comparable to CATC in delivering automation retrofits and newbuild control systems for marine clients.
• Alphatron Marine: Marine electronics and automation specialist (part of JRC/Alphatron) providing integrated bridge and vessel automation solutions. Overlaps with CATC in marine control/SCADA integration and aftermarket service for commercial vessels.
• Høglund Marine Automation: Norwegian specialist in ship automation and control systems (power management, HVAC, engine room). Closest comparable to CATC in size, geography, and marine HVAC/automation focus, targeting similar vessel segments.

Regional players

• Elomatic: Finnish marine and offshore engineering consultancy with automation and HVAC design capabilities. Comparable to CATC in Nordic marine engineering footprint, though more design-consulting oriented than turn-key automation delivery.
• Stemmann-Technik: German supplier of marine HVAC, power, and automation solutions. Comparable niche focus on marine heating, ventilation, and energy systems, primarily serving European shipyards and operators.
