Motivation

• Mission profile is not yet in the scope of AMC

• Consequences 2 year mission OPV in Caribbean Sea unknown


Research question

Main:

‘What are the effects of the deployment of maritime assets in the Caribbean Sea for a long period of time

… and how should asset owners use this information to achieve cost effectiveness of those maritime assets?’


Research strategy

• Literature study

• Field survey

• Case study

Failures

RandomSystematic Common Cause

Corrosion Abnormal proces conditions

Wear and tear


Failures (corrosion)

Variables that influence corrosion rate metals:• Concentration (salt)• Temperature• Catalytic Conversion (pollution)• Distribution rate (current)

Polymers:• UV-radiation

Setting up an analysis model

• Maintenance: RCM

• Logistics: ILS (logistic support analysis)

• Management Control: AMCS (asset management control system)

Input Variables:- Corrosion rate- UV degradation- Running hours- ……

Identify Mission related failure modes

Updated AMCS:- LCM-team- LCM-model

RCM review ILS review (LORA, support elements

Field Survey

Interviews and infra

• Goals: verify variables, define new variables + (motivation)

• Representatives from DMO, RNLN, RNLN Carib, customs, RMar

Interviews and infra - results


Data analysis case 1


Data analysis case 1 - results

• Between €350.000,- and €400.000,- per year CGC

• €300.000,- per year Customs


Data analysis case 2


Data analysis case 2 - results

• Bloys higher maintenance load for: deck equipment, radars, antennas, diesel generators, chillers, HVAC and canon

• Almo higher maintenance load for: Replenishment at Sea installation

(differences > +50 %)


Field survey - conclusions

• Availability of data is poor

• Results literature are validated, installations with priority further analysis are presented in field survey.

• Interview results and table with variables should be used to create alternative ILS plans


Case Study

Case study - general

• Conservation system – corrosion related• Diesel generators – process conditions

• Mission specific managment control


Conservation

• FMEA: corrosion related failure modes identified

• RCM: alternative maintenance strategies defined (intervals)

• LORA: alternative maintainers defined


Conservation

• AMCS

New product actor combinations:

- Products: periodical inspections on site

- Actors: ILM specialist + local contractor

- Base line data (cost and performance)


Conservation

Diesel generators

• FMEA / RCM -> use based (running hrs)

Mean hrs per diesel engine• Den Helder: 5120 hrs / two years• Willemstad: 7200 hrs / two years

3000 hrs maintenance planning important !


Diesel generators

• LORA

3000 hrs maintenance by shore support or local contractor (not crew)

• AMCS

- Products: 3000 hrs maintenance

- Actors: shore support or local contractor

- Base line data (cost and performance)


Diesel generators

• Business Case: cost vs benefit

COST• Local contractor

cost• Spares in stock• Training

BENEFIT• Increase of

availability (better planning)

• Reduce maintenance load crew

• Less ad hoc


Management Control

• Life Cycle Management System (model)

• Life Cycle Management Team


Management Control

• LCM system (model of AMCS)

- Model of technical system- Model of product actor combinations - Model of cost and performance data


Management Control

• LCM system – mission profiles


Management Control

• LCM team

Team building Creation of LCM-model Mission specific team members? Evaluation plan


Case study - conclusions

• Analysis model works• Potential in saving cost and increasing

availability• RCM II not always applicable• Workload to create alternative ILS plans is

minimal• Management Control preparations should

start in time


Case Study - Conclusions

Input Variables:- Corrosion rate- UV degradation- Running hours- ……

Identify Mission related failure modes

Updated AMCS:- LCM-team- LCM-model

Maintenance review

ILS review (LORA, support elements

Alternative ILS plan


Conclusions and recommendations

Answer research question

• Caribbean Sea is more corrosive and use profile is different

• Input variables can be defined to identify mission related failures

• Effects on installations summarized in table (results field survey)

• Asset managers should analyze installations according to analysis model

• Alternative ILS plans should be processed in the AMCS


Recommendations

Research:• Method for spare part optimization• Research generic applicability of analysis model• Define generic input variables

Projects:• Involve a corrosion specialist in designs• Create alternative ILS plans, LCM team and

LCM model !!!!
