VTS Service – Short introduction

MPS Group

Vessel Traffic Service (VTS)

improve vessel traffic safety and

efficiency

Protect the environment

VTS information service

Information and warnings

For guidance only

VTS Service – Challenges and shortcomings

MPS Group

Qualified personnel – advanced technology Cognitive challenges – from overload to boredom Swedish maritime traffic – large areas, low traffic density Geographical complexity – archipelagoes Complex collaboration with different stakeholders

MPS Group

Design of a new VTS Centre –The project

Demand for a UAE Vessel Traffic Service with increased efficiency and maintained safety and quality

Project goals High Customer Satisfaction, User friendly environment and high

efficiency through standardized ways of working in an ergonomically adapted work place with optimized possibilities of cooperation.

How? Pilot (Pre) study as input to Design Work with continuous

analyses and evaluations along the way.

The HTO Concept as a tool

MPS Group

A mix of methods and experiences from different contexts such as O&G (offshore), Nuclear, Railway and Aviation.

Tight involvement of operators and other relevant personnel including management through the HTO Concept

”Process type” method with an iterative design approach

The HTO Concept as a tool–1: Pilot (Pre) Study

MPS Group

Combined Situational& Functional Analysis

Following ISO 11064 with ”HTO-twist” Observations Interviews Workshops

Understanding of the Working Situation Pinpointing of problem areas Benefits in existing Design Solutions

Used as input to the Design Phase

MPS Group

The HTO Concept as a tool–2: Design Work*

Phase A –Layout &Organisation

Phase B –Operator Work stations & HMIs

* Also included detailed analysis methods such as Task Analyses

Concrete results–Increased Efficiencyin the VTS

The numberof VTS Centres was reduced from four to three

35 VTS Operators deliver the same service as 42 did before

Outsourced services worth1,5 MSEK/Year where in sourced and absorbed into the VTS organisation

Total production costs for the delivered services decreased by 15%

The VTS Centre –Before…

MPS Group

Layout

• Back to back• Consoles blocking light from windows• Entrance from behind • L-shaped room

Organisation

• Three VTS positions • Together with pilot planning service

(two positions)

The VTS Centre –After…

MPS Group

Layout

Face to face Shoulder to shoulder(in pairs) All movement in front of operators

(improved social situational awareness) Improved natural light

Organisation

Two VTS operators and ones semi-administrative position

Pilot planning separate

The VTS Centre –Before…

MPS Group

Work stations

Horse shoe desks Much turning and twisting Limited access for second

operator (shift changes and support)

HMIs

Small computer screens Geographical areas fragmented

(mental rotations)

The VTS Centre –After…

MPS Group

Work stations

HMIs Large screen areas –support for high

geographical complexity Most needed tools closest at hand Large, curved desk surface allowing

flexibility

Co-operation

VTS position shoulder-to-shoulder Balanced overhearing improving

situational awareness Covering for each-other at shorter breaks

MPS Group

Conclusions–Benefits of using HTO

All embracing concept and analyzing tool Pinpointing problems as well as benefits of existing solutions, organisation

and technical systems Fits well in to a process such as the ”ISO 11064” Efficient tool that, correctly used, creates an ownership to the design

solutions as well as the process to get there.

But.. Despite the obvious benefits of proposed design solutions, project goals

might be missed if they are not properly secured with internal as well as external stakeholders…

Benefits of using MPS ME Benefit we have knowledge abut ADMA

Highly qualified/ competent project member, best in Europe

Able to take the project from start to drifting MCC

Top technical and communication solutions

We will, thru our contacts be able to take advantage from existing MCC in oil and gas (north sea CONOCO Philips and Statoil) and Aviation

Project team will have redundancy and capabilities too get employees in existing MCC to join the team for shorter or longer periods.

Project Manager will be in Abu Dhabi during the hole project and have contacts and knowledge about the oil and gas industry in the area.

MPS ME have the recourses to work parallel to develop control room, charts, survilance (radar, AIS and communication)

MPS Group

WHAT TO DO

Analysis of existing offshore activity

Develop sailing routs and chart ( points of pilot, reporting positions)

Develop MCC control room

Radar, VHF and AIS positions

Documentation

Sailing and communication procedures

Emergency Preparedness communication proceedures

Oil spill surveillance and preparedness

Train the MCC personnel
