DP system assessment
Power generation and distribution, thrusters, position reference systems and DP control configuration.
DP & FMEA Trials
Dynamic Positioning Assurance for Critical Offshore Operations
Vessel-specific DP audits examining system performance, redundancy, documentation and operator competence.

- ASOG / CAM / TAM
- FMEA / FMECA
Overview
A DP audit asks a single practical question in many different ways: if this vessel loses a component while working, what happens next? Answering it requires examination of the power plant, thrusters, references, control system, maintenance regime and the people on watch.
Our audits are vessel specific. Findings are written against the vessel's own configuration and intended operation rather than against a generic template.
Scope of work
- Review of the vessel's DP FMEA and most recent trials results
- Single line diagram and power management system configuration
- Thruster configuration, control and protection
- Position reference system arrangement, diversity and redundancy
- Environmental sensor arrangement
- DP alarm, warning and status monitoring practice
- Planned maintenance of DP-related systems and critical spares
- ASOG, CAM and TAM documentation against actual operations
- DP operator competence, familiarisation and record keeping
- Findings report with prioritised technical recommendations
What we provide
Redundancy verification
Review of the worst case failure design intent and how it is reflected in operating practice.
Documentation review
FMEA, trials results, ASOG, CAM and TAM, DP operations manual and capability plots.
Competence and operations review
DP operator certification, familiarisation, logging practice and watch arrangements.
Frequently asked
- How does a DP audit differ from proving trials?
- An audit is an examination of documentation, configuration, maintenance and practice. Proving trials are a practical demonstration that the system behaves as the FMEA predicts. They complement each other.
- Do you assess DP operator competence?
- We review certification, familiarisation records, logging practice and watch arrangements. We do not issue DP operator certification.
- Is a DP audit a regulatory requirement?
- Requirements vary by flag, class, charterer and field. We do not present our work as regulatory approval; it supports the vessel's technical evidence base.
- What is the worst case failure design intent?
- It is the statement of the single failure the vessel is designed to withstand without losing position. Everything in the redundancy concept follows from it.
- How long does an audit take?
- Typically one to three days on board depending on vessel complexity and DP class.
