DP Consultancy

Our standard and bespoke consultancy enables clients to optimise their operational application and extract the maximum value from their vessels, resulting in improved quality, productivity and safety.



Following the delivery of a vessel from the yard on build, an FMEA should be conducted or updated at five-yearly intervals and whenever a major change has taken place on board the vessel. We can conduct FMEA trials on board a DP vessel anywhere in the world. Working with the crew and client’s representative, we ensure timely and professional delivery, with the final, comprehensive report meeting both client and operator needs and standards.

Instances when an FMEA needs to be updated include:

  • At the beginning of a cycle (new product/process)
  • When changes are made to the operating conditions
  • When a change is made in the design
  • When new regulations are instituted
  • When customer feedback indicates a problem

DP audits and design

We can carry out Gap analysis for upgrades and standardised DP audits on all types of drilling rigs and offshore vessels – including diving support, heavy lift, pipe laying, trenching and ROV support vessels – ensuring each workscope is fit for purpose.

We also have extensive experience in writing DP Operation manuals for these vessels, available through a choice of media.

DP audits and sea trials are designed to identify any potential single-point failures which, if occurring when the vessel is operating on DP, could cause the vessel to move from its intended position and threaten the safety of the operation. They also help to prove the position-keeping capability of the system.

If any failure modes are found, recommendations are made either to modify the system if practical, or to adapt the operational procedures relevant to the workscope. Our methodology is to industry standards and has been comprehensively enhanced through the knowledge we have gained from experience and incident analysis.

Other services

C-MAR provides DP vessel operators with Activity-Specific Operating Guidelines (ASOG), defining vessels’ Critical Activity Mode of Operation (CAMO) & Task Appropriate Mode (TAM), in the form of vessel specific guidelines including accessible reference tables.
