OneStep Power specializes in making challenging marine assurance tests for Shuttle Tankers simple.

DP FMEA Assurance Framework

Since OCIMF released the DP FMEA Assurance Framework Risk Based Guidance in 2020, Shuttle tanker operators have been asked to validate their cross-connected control systems. These systems are vital to the operation of the vessel, and in some cases, removing the cross-connection isn’t possible. OneStep Power is here to help.

We work with you to validate that these cross-connections don’t represent a risk to your DP operations, we give you the data to provide to your client, so you can get back to work fast.

We work with you

We work with you to validate that these cross-connections don’t represent a risk to your DP operations, so you can provide data to your client, and get back to work fast.

We can work with your crews, either during sea trials after your shipyard survey, or during the transits between field and port.


Generally, testing can be completed in 3 days, with standard cross-connections being validated in just under an hour.

Since 2020, OneStep Power’s ShortCUT technologies have been the proven way for DP shuttle tankers to quickly validate their safety-critical system design and meet contracting deadlines.


Benefits of our testing

  • Get on contract by using data-evidenced testing

  • Fast, no-impact testing, can be done in transit on DP

  • Removes the headache of isolating power supplies through administrative controls

  • Our team handles the testing - your crew can see results immediately

  • Trusted by major DP assurance providers and charterers

  • Team experienced with global operations, we have delivered ShortCUT testing on 6 continents

Our DCShortCUT validates the fault tolerance of cross-connected 24V DC power supply configurations through in-circuit failure mode testing.  ​ - Reduces risk by removal of personnel - Single integrated test solution reduces cost - Repeatable tests with clear pass/fail criteria - Vessel protective functions remain “as-is” - Invisible to the vessel - Responses are as if there was an actual fault The DCShortCUT is temporarily installed to the system under test. Using a controller and HMI, the DCShortCUT induces a series of faults on the 24V DC system. ​ - Load step tests - Overload tests - Short circuit - Short to ground  - Over-voltage - Failure of power The DCShortCUT provides a safe and reliable method for performing testing, which can be repeated on a regular basis.

Case Study


What you get

OneStep Power will provide a detailed on-site test plan which can be communicated to your client in advance of the testing.

While onboard, client witnesses can observe real-time results. After testing, the full suite of test results is provided as a preliminary report, so you can get to work, while the final results are analyzed by our automated validation algorithm and the final report is produced.
