AutoSea
Automation and operator systems for maritime and offshore work
Automation Built Around the Operation
AutoSea provides building blocks for data acquisition, alarms, logging, control logic, and operator screens, delivered with the control hardware, panels, I/O, protocol integration, installation, and commissioning needed for a working system.
- Deterministic scan-cycle runtime with I/O polling
- HMI builder with vector graphics and real-time process displays
- Full industrial and maritime protocol stack
- Configurable alarm and event management
- Historian, replay, and audit trail
- Integrates with TwinSea (HIL testing) and MetroSea (metrology feeds)
Platform Architecture
AutoSea components can be used independently or combined with hardware, panels, and field integration into a larger monitoring and control system.
AutoSea Runtime
The core execution engine. Handles deterministic scan-cycle execution, I/O polling, process variable management, alarm evaluation, and inter-module communication.
I/O Modules
Hardware-abstracted I/O drivers covering digital I/O, analogue I/O, serial and network interfaces. New hardware drivers can be added without modifying application logic.
HMI Builder
A vector-graphics HMI development environment for building operator screens with real-time process graphics, trend displays, alarm views, and navigation structures. Screens run in-browser or as a native application.
Protocol Layer
Communication adapters for Modbus (TCP/RTU), OPC UA, NMEA 0183/2000, MQTT, CAN (CANopen, J1939), Siemens S7, EtherCAT, and Ethernet/IP. Protocol-specific parsing and engineering unit conversion handled at the layer boundary.
Deployment Toolset
Configuration management, version control, and deployment tooling. Includes remote update mechanisms, health monitoring, log management, and backup/restore.
Protocol and Integration Support
AutoSea's protocol layer handles the full range of industrial and maritime communication standards used across the offshore sector.

MimeSeas Platform Integration
AutoSea systems can be connected to TwinSea digital twins for control logic validation before site deployment. Changes to AutoSea control sequences can be regression-tested against the TwinSea model without live equipment.
AutoSea receives live metrology data from MetroSea sensors, feeding positioning and alignment data directly into the automation logic. Used in pipelay tensioner control, offshore installation alignment, and structural load monitoring.
SimSea generates virtual I/O signals that drive AutoSea as if connected to real field instrumentation. Enables operator training scenarios where the SCADA/HMI system responds to simulated vessel and equipment behaviour.
Application Domains
Dredging Automation
Full automation for TSHD and CSD dredging operations. AutoSea interfaces with dredge pump drives, cutter head drives, spud control, drag arm positioning, overflow systems, and dredge production monitoring.
Vessel and Platform Systems
Vessel monitoring and control for AHTS, PSV, pipe-lay vessels, cable-lay vessels, and platform topsides. Covers DP system interfacing, ballast and tank management, power management, and auxiliary systems automation.
Pipelay and Offshore Installation
Tension control, stinger angle monitoring, J-lay and S-lay operation automation. Pipelay tensioner control, departure angle management, and integrated metrology feed from MetroSea.
Shore-Side and Remote Operations
Shore-based control rooms, remote monitoring of offshore assets, and fleet data aggregation. AutoSea supports both local and cloud-hosted deployment models.
Service Models
End-to-End Delivery
End-to-end AutoSea system delivery: requirements capture, system design, hardware specification, software development, factory acceptance testing, site installation, and commissioning.
Software Licensing
AutoSea platform licensed to your engineering team for in-house development of monitoring and control applications. Includes developer training and technical support.
System Migration
Migration from legacy SCADA and DCS platforms to AutoSea. We handle data model translation, HMI redesign, historian migration, and parallel running periods to ensure continuity.
Managed Service
MimeSeas operates and maintains your AutoSea system under a managed service agreement, covering software updates, hardware maintenance, and 24/7 support.
