— From Legacy Relay Panel to Modern Control System
When ageing control systems become a liability at sea, QualShips Australia delivers end-to-end auxiliary engine controller renewals that restore reliability, reduce downtime risk, and bring vessels back into class compliance.
The Problem with Ageing Auxiliary Engine Controllers
Legacy relay-based control panels found on many vessels in service today were designed for a different era. Over time, these systems suffer from:
• Deteriorated wiring insulation and loose terminations
• Failed or intermittent relay contacts causing spurious trips
• Obsolete components with no replacement parts available
• Non-compliance with current class survey requirements
• Increased fault-finding time during critical operations
The result is unpredictable engine behaviour, extended port stays, and costly off-hire exposure for owners and operators.
QualShips Solution — Full Controller Renewal
Our engineers carry out a complete like-for-like or upgraded controller renewal, covering:
• Full removal of the legacy relay logic panel and associated wiring
• New DIN-rail mounted PLC or relay logic assembly to OEM or equivalent specification
• Neatly routed, colour-coded, and ferrule-terminated wiring throughout
• Clearly labelled terminal blocks for ease of future maintenance
• Functional testing of all start, stop, alarm, and protection circuits
• Load test and sea trial verification where applicable
• Handover documentation including updated circuit diagrams
Why Proper Termination and Wiring Management Matters
A clean, well-organised panel is not just aesthetic — it is a safety and reliability requirement. Loose or bundled wiring creates heat build-up, makes fault-finding difficult during emergencies, and is a common cause of repeat failures. QualShips engineers apply marine industry best practices to every installation, ensuring the renewed panel meets the standards expected by class surveyors and vessel operators alike.
Classification Society Compliance
All QualShips controller renewal work is carried out in accordance with applicable class requirements. We work directly with DNV, Bureau Veritas, Lloyd’s Register, and other societies to ensure survey attendance, approval of materials, and issuance of certificates where required.
Serving Vessels Across Australian Ports
QualShips Australia provides auxiliary engine controller renewal services across all major Australian ports including Sydney, Port Hedland, Brisbane, Fremantle, and Newcastle. Our attending engineers mobilise rapidly to minimise vessel turnaround impact.
