ABL Secures DNV Approval for Innovative DP2 Stern Thruster Changeover Concept
ABL has successfully secured DNV approval of a preliminary design concept for an enhanced stern thruster changeover solution on a DP2 vessel.
The approval marks an important milestone in the development of practical, class‑aligned DP retrofit solutions, strengthening operational robustness while addressing charterer confidence.
The Industry Challenge
DP2 vessels configured with two main propellers and a single stern thruster can face operational vulnerabilities during changeover. While the configuration may be class‑compliant, conventional auto‑changeover philosophies can introduce short‑term risks to electrical system reliability during thruster transfer and restart.
As a result, formal compliance does not always translate into charterer acceptance, raising commercial and operational concerns around system performance.
ABL’s Solution
ABL’s operations in Egypt developed a fast‑response stern thruster changeover philosophy designed to close the gap between compliance and operational resilience.
Developed under an existing master service agreement (MSA) Maridive and Oil Services (MARIDIVE), the concept was designed to:
- Maintain DP redundancy principles
- Minimise transfer interruption time to the lowest technically achievable level
- Prevent fault propagation between redundant groups
- Enhance post‑failure position‑keeping capability
“This DNV approval confirms that advanced engineering solutions can bridge the gap between compliance and operational robustness. As the industry increasingly focuses on DP upgrades and retrofits, structured electrical design concepts like this will play a key role in improving both technical resilience and charterer confidence.”
Juan Antonio Vieiros Canal, DP Lead, Middle East, North & South Africa and India
Global Standards, Delivered Locally
The achievement reflects both the technical strength of ABL’s in‑country DP and electrical design team in Cairo, and the team’s close collaboration with the client, to deliver long‑term value and improved DP asset performance.
“Our value lies in delivering cost-effective solutions through timely mobilisation of qualified resources, supported by a deep understanding of regional market dynamics and regulatory requirements. This approach enables efficient stakeholder coordination, improved turnaround times, and consistently high levels of client satisfaction.”
Tamer Gamil, Country Manager, ABL Egypt
The team’s scope of work covered engineering development, simulations, and class engagement.
Widely recognised as the market leader in marine assurance services in Egypt, holding approximately 90%+ market share locally, Juan Antonio Vieiros Cañal adds:
“I am extremely proud of the Cairo team for delivering a concept that combines sound engineering, regulatory alignment, and commercial relevance.”
This solution opens new retrofit opportunities for DP vessels seeking to strengthen post‑worst‑case failure (WCF) performance and improve charterer acceptance.
