When operating vessels offshore at maximum efficiency with a small crew, getting the ‘right information at the right time’ to be able to schedule preventative maintenance before an issue arises has been the traditional challenge for many crew transfer vessel operators.

One new solution that addresses this problem is a vessel planned maintenance system, with near real time remote vessel sensing and alerts.

Vessel planned maintenance applications have been widely adopted for many years and it is now well understood that by integrating the new AST maritime remote sensing and engine diagnostic system, iRAMS,with a preventative management system can offer a solution that provides the ‘right information at the right time’ for a vessel operating globally.

The iRAMS/AST–Planned Maintenance System has been developed specifically for the maritime market, playing an integral part of any vessels SEEMP strategy, reducing emissions and meeting compliance regulations. Remote vessel management offers reduced down time for unplanned engine maintenance, automation of daily reports, reduced fuel consumption, (including monitoring Skipper behaviour) and combines engine diagnostics and automated vessel efficiency reporting.

Predictive maintenance (PdM) techniques are designed to predict when routine servicing maintenance should be performed. This offers genuine cost savings ensuring servicing tasks are performed only when required. As tasks can be scheduled in advance, Operation Managers can avoid expensive, unplanned servicing and decrease incidents that may cause breakdowns of vessels out on contract.


A new feature under trial within the combined iRAMS/AST-Planned Maintenance System solution is a vibration analysis and alerting module. Vibration sensors record data from the vessel which is then transmitted remotely and automatically populate the shore side PMS application.

The PMS application constantly monitors the vibration data and automatically alerts the vessel owner when the vibration data parameters are outside the preconfigured normal operating values, giving an early indication of routine servicing is required on a specific component – engines, shaft etc.

Alerts are available shore side by way of a traffic light system and a logon message generated each time the application is accessed, providing “the right information at the right time”. This means vessel operators have near real time vessel information to be able to schedule routine maintenance and avoid expensive, unplanned breakdowns increasing the operational efficiency of the vessel.
