An AMC approach to deal with the influences of the mission environment on maritime assets

“The influences of the mission environment ‘Caribbean Sea’ on the OPV and relations of these influences to the need for maintenance and the resulting need for logistic support and management control.”


In his recommendations of ‘Cost Effective Management Control of Capital Assets’, Stavenuiter suggests to enlarge the scope of Asset Management Control (AMC). One of his recommendations is to include the ‘mission profile’ in the scope of AMC. As the title suggests, this dissertation discusses the use of AMC methods to deal with the influences of  the mission environment on capital assets. The Dutch defence organization offers an interesting research environment and specific cases to execute the research. 

The number of tasks low in the spectrum of violence is increasing. Those tasks are mostly executed in peacetime, like counter drugs operations, law enforcement, maritime presence protection (pirates) and humanitarian aid. The Dutch Defence organization is acquiring four Offshore Patrol Vessels (OPV) to fulfill this operational need. One of the primary mission areas are the Netherlands Antilles and Aruba, in the Caribbean Sea. The Royal Netherlands Navy (RNLN) has the intention to continuously station one op the OPV’s in the Caribbean Sea for the duration of two years.
The belief among many engineers within the RNLN is that a maritime asset degrades faster in the Caribbean Sea than in Dutch waters, like the North Sea. This belief is supported by some scientific reports. In the system plan for the OPV no attention is yet given to future deployments for two years in the Caribbean Sea. If the OPV will indeed degrade faster in the Caribbean Sea, than the RNLN might encounter serious problems with maintenance and logistic support for the OPV.

This dissertation aims to clarify the relation between a long term mission in the Caribbean Sea and the degradation of a maritime asset. With this information it aims to describe the impact on the need for maintenance and the resulting need for logistic support. It also aims to identify steps to be taken for asset managers for effective management control of the OPV in this specific mission.
From the aims of the dissertation the following main research question is derived:
“What are the effects of the deployment of maritime assets in the Caribbean Sea for a long period of time on installations and how should asset managers use this information to achieve cost effectiveness of those maritime assets?”

The research strategy was qualitative and quantitative in nature and consisted of a literature study, a field survey and a case study. The literature study focused on defining input variables to describe a mission in the Caribbean Sea and on developing an analysis method. The field survey was used to validate the resulting variables of the literature study and consisted of interviews, an exploration of the infrastructure in the Caribbean Sea and two data analysis cases. In the case study two installations of the OPV were investigated with the use of the results of the literature study and the field survey.

The research revealed that the Caribbean Sea is a more corrosive environment than the North Sea. Also the use profile for a selection of installations is different. It is possible to describe the operational environment as a function of multiple variables and to analyze the effects on installations. Asset managers should use this information to achieve cost effectiveness of the asset by adapting the maintenance plan, the logistic processes and management control activities to the operational environment.
It is possible to summarize all steps to be taken in an analysis model. This analysis model has been validated in the case study and proven to lead to useful results. The case study indicates that the analysis model has the potential to be effective in saving cost and increasing operational availability.

Important conclusions of the research are:

  • The Caribbean Sea is a more corrosive environment than the North Sea. Besides Corrosivity, other variables must be taken into account to determine the effects of the mission environment on installations. Those variables are: use profile of installations, local infrastructure, working conditions and human factors.
  • It is possible to define an approach to deal with the influences of the mission environment on maritime assets. This approach is summarized in an analysis model. Since this model is based on generic literature sources, it is expected to be generically applicable.
  • It is difficult to retrieve reliable data, to use to compare similar assets. To be able to optimize the maintenance and logistic processes of the OPV in the future, the Life Cycle Management (LCM) team must set up an evaluation plan to collect data and store data from the start of the exploitation phase.
  • The set up of alternative ILS-plans for the Caribbean Sea has the potential to reduce cost and to increase availability, compared to the use of standard ILS-plans. The LCM-team should use the alternative ILS-plans as an input to define a vision on cost-effectiveness and a road map for the life cycle management of the OPV. A system model, like AMICO, should be used to store this vision.
