Background

• Possible development of European wide Database under auspices of EMSA

• Timely to review ‘lessons learned’ in publishing the Analysis from 1997

Page 4: 1 UK Seafarers Analysis : Ten years on David Glen CITM London Metropolitan University Presentation to IMSF Conference April 2007

Origins of Present ‘Analysis’

• State of play in 1997

• Use of STCW78 information

• Original criteria for ‘counting seafarers’– Certificated officers– Ratings– Cadets

Page 5: 1 UK Seafarers Analysis : Ten years on David Glen CITM London Metropolitan University Presentation to IMSF Conference April 2007

Period of Transition

• Creation of MCA SDS database in 1998

• Fully operational in 2002

• Use of overlapping databases

• Generated some instability in numbers

Page 6: 1 UK Seafarers Analysis : Ten years on David Glen CITM London Metropolitan University Presentation to IMSF Conference April 2007

Widening Scope of STCW95

• Yachts - MASTER (yachts) identifiable

• Tugs and Inshore Craft

• CECs on UK registered vessels

Page 7: 1 UK Seafarers Analysis : Ten years on David Glen CITM London Metropolitan University Presentation to IMSF Conference April 2007

Uncertificated officers

• Not germane to ‘Strategic Interests’

• Germane to employment and significance of sector

• Measured through UKCoS Manpower Survey

Page 8: 1 UK Seafarers Analysis : Ten years on David Glen CITM London Metropolitan University Presentation to IMSF Conference April 2007

Ratings

• UKCoS main source

• RMT database also examined, but not used

Page 9: 1 UK Seafarers Analysis : Ten years on David Glen CITM London Metropolitan University Presentation to IMSF Conference April 2007

Cadets• Originally used GAFT• Now use

– Data from SMaRT– Cross referenced with MNTB data from

training colleges and training providers

• Issues– SMaRT includes EU nationals– Central database mooted but not developed– UK Data Protection Act used as barrier

‘The Active Seafarer’

• Certification method overstates numbers– Proportion ‘Active’ estimated

• NUMAST survey 1999• Cardiff University study of on-shore employment

– Use 16%– Is an issue still

Seafarer Retirement• Two types

– Retirement from ‘active at sea’– Retirement from working population

• Deal with former by assuming a ‘wastage rate’ per year

• Original assumptions were 57 and 65.

• Now deal with latter by modelling a distribution around mean age of 62.

Page 12: 1 UK Seafarers Analysis : Ten years on David Glen CITM London Metropolitan University Presentation to IMSF Conference April 2007

12

Model Assumptions

• Age profile of existing cert officers taken

• Numbers and age distribution of new OOW officers based on cadet entry and wastage rates

• ‘Wastage rates’ for 20-40, 40 to retirement

• Retirement Age distribution applied around mean of 62

Forecast Performance• Not good

• Consistently forecasting gloomier future than reality

• Sources of error– Data – Cadet entry numbers – Assumptions on wastage rates– Model itself flawed

Page 16: 1 UK Seafarers Analysis : Ten years on David Glen CITM London Metropolitan University Presentation to IMSF Conference April 2007

Forecast Performance

• Data– STCW95 widened scope so numbers are not

strictly comparable– Can adjust for these differences

None of these were included in the 1997 data.

Lessons for EMSA• Consistency in definition of ‘active seafarer’• Core competencies should be identified – I.e. should

‘Tug & Inshore craft’ be included • Standard format for data transmission between national

agencies & EMSA• Independent Hyperbase or Snapshot of data from

National Agencies• Compliance with National & EU Data protection

legislation may generate issues• Database design should be driven by information

requirements, not admin needs • Certification ignores Ratings and Cadets – how to

measure and monitor?• Projection models – alternatives to the Stock-flow eg

demand based models?

Concluding Remarks

• Given the impression all is doom and gloom

• Very great improvement since 1996

• Expect that further improvements will take place in the next 10 years
