A s a measure of its perceived

im-portance, in order to facilitate

the use of Electronic Chart

Dis-play systems (ECDIS) in shipping,

Den-mark, Estonia, Finland, France, Norway

and Sweden have taken an unprecedented

step and decided to reduce the

recom-mended retail price of their Electronic

Navigational Charts (ENCs) by 70%.

In March 2001, the Baltic Carrier and Tern

collided in Kadetrenden between Denmark

and Germany causing an oil spill of 2,700

tonnes of heavy fuel An extraordinary

meet-ing of Ministers of Transport and the

Envi-ronment from the countries surrounding the

Baltic Sea was convened in Copenhagen and

a declaration was adopted containing a large

number of measures to improve the safety

of navigation in the Baltic Sea and to increase

response capacity to accidents This was the

Copenhagen Declaration (see Note 1 at the

end of the article) Due to its unique

char-acteristics, ECDIS was identified as one of

the major contributors to increased

naviga-tional safety

The central parts of the Copenhagen

Decla-ration aimed at promoting the use of ECDIS

have been transferred to the Helsinki

Con-vention, making the measures binding on

governments The revised text of the

con-vention concerning ECDIS is as follows:

Regulation 9: Improved hydrographic

serv-ices and promotion of the use of Electronic

Navigational Charts (ENC)

1) The Contracting Parties:

a) shall develop a scheme for systematic

re-surveying of major shipping routes and ports

in order to ensure that safety of navigation

is not endangered by inadequate source

in-formation The survey shall be carried out

to a standard not inferior to the latest edition

of IHO S-44 The scheme shall be elaborated

Facilitating the use

of ECDIS

By Steen Nielsen and Ole Berg

jointly by the hydrographic services respon-sible for the areas in question not later than

by the end of 2002 with the aim to begin implementation by 2003

b) shall develop Electronic Navigational

Charts (ENC):

i) for major shipping routes and ports by the end of 2002 Major shipping routes and ports shall be selected on the basis of vol-umes of dangerous goods and number of passengers; and

ii) for secondary shipping routes and ports

by the end of 2004

2) The Contracting Parties:

a) shall accept Electronic Chart Display

and Information Systems (ECDIS) as equiva-lent to paper charts in accordance with Chap-ter V of SOLAS;

b) undertake to enter into negotiations with

shippers and recipients in their States, who are involved in transport of goods to and from ports in the Baltic Sea Area, with the aim that the commercial parties (e.g national shippers and receivers) make arrangements

to the effect that:

i) ships with a draft of 11 metres or

more, and for the Sound oil tankers with

a draft of 7 metres or more, chemical

tank-ers and gas carritank-ers irrespective of size and

ships carrying a shipment of INF cargo carry

ECDIS;

c) shall by the end of the year 2002 as a

matter of particular interest ensure that port

State control of paper charts is intensified

on board ships with a draught of 11 metres

or more, and for the Sound oil tankers with

a draft of 7 metres or more, chemical

tank-ers and gas carritank-ers irrespective of size and

ships carrying a shipment of INF cargo

This change to the Helsinki Convention is

unique as it is the first internationally

bind-ing instrument that mentions:

1. Regular surveys of shipping routes,

2. the development of Electronic

Naviga-tional Charts, and

3. the carriage of ECDIS

In addition, the above-mentioned actions are

introduced with fixed implementation

dead-lines, a very unusual step that fully

under-lines the contracting parties’ recognition of

the importance of these measures

The effect of the measures is that from the

end of 2002 full ECDIS navigation will be

possible on all major shipping routes and to

all major ports in the Baltic Sea From the

end of 2004 the same goes for the entire

Baltic Sea and the approaches to the Baltic

Sea Full ECDIS navigation has been

possi-ble in all Danish waters from July 2000

The contracting parties to the Helsinki

Con-vention are Estonia, Denmark, Finland,

Ger-many, Latvia, Lithuania, Poland, Russia,

Sweden and the European Union Of these

countries, Denmark, Estonia, Latvia, Finland

and Sweden are, together with France,

co-operating with Norway on providing central

access to their official ENCs, which are

needed for full ECDIS use, i.e paper charts

need not be carried if an adequate back-up

system for ECDIS is available

The seven countries have also decided that

the price of the ENCs must not inhibit the

take-up of ECDIS and this is the reason for

the 70% reduction in the recommended

re-tail prices (See Note 2 for further

informa-tion and a list of distributors.)

ECDIS is far more than a digital chart, it is a

decision support tool of a kind that has never before been available on the bridge of a ship

ECDIS allows for real-time navigation and monitoring of a ship’s position and move-ments but it is the ability to integrate infor-mation from all navigation sensors and par-ticularly Radar, ARPA and AIS into a single comprehensive and easily readable picture that holds the true power of ECDIS

On a bridge without ECDIS, the Master has

to make all the necessary correlations be-tween the radar image, ARPA targets, fixed and floating aids to navigation depicted on the chart, the navigable part of the

water-way, the plotting of positions on the chart and the dead-reckoned and estimated posi-tions allowing for drift induced by wind, etc

in his head, supported by drawings and cal-culations performed on the paper chart

In confined and congested waters it is a task that greatly raises the stress level on a ship’s bridge, and these scenarios are loved by all instructors in bridge resource management and exploited to the fullest in their attempts

to introduce maximum stress in ship han-dling simulators ECDIS takes away the stress caused by the need to keep track of all the information necessary to make the

Without ECDIS - a high stress level on the bridge

ECDIS allows the Master to focus on making the right decisions in a timely and controlled manner.

appropriate decisions in the head and

will allow the Master to focus on making

the right decisions in a timely and

control-led manner

In addition, ECDIS enables automatic

up-dating of chart information, thus relieving

navigators of the tedious job of correcting

charts on costly overtime and further

re-moves the risk of them making errors in the

process It is precisely these characteristics

that will help reduce the human error that is

the source of most collisions, groundings and

near misses at sea

In the following accounts it is important to

note the distinction between ECDIS, which

is a type-approved system, and Electronic

Chart Systems, which are not

type-ap-proved Ships carrying ECDIS need not

carry paper charts

A.P Moller Group

In December 2001, the A.P Moller Group

decided to retrofit 160 vessels with ECDIS

following extensive trials conducted by

sen-ior navigators with extensive experience of

navigation on traditionally equipped bridges

Captain Hans Peder Mikkelsen, Marine

De-partment, gives some of the rationale behind

the decision taken by A.P Moller Group:

“One of the core reasons was the decision

support provided by using the ECDIS in all

phases of the voyage, from route planning

to the end of the voyage Particularly during

passage of shallow and trafficked waters,

ECDIS significantly reduces the workload

of the navigator and enhances the situation

awareness on the bridge

The system’s unique ability to combine the

radar image with the chart image by a single

action gives an immediate and constant

con-firmation of the navigators’ decisions The

information about other ships provided by

AIS, which will be implemented in

accord-ance with the new SOLAS Chapter V, will

most naturally be displayed on the ECDIS

display to further increase the knowledge

about other ships in the area

During ocean passage, the ability to

com-bine forecasts on weather, sea and swell with

the planned route allows for on site weather

routing quickly and easily resulting in fuel

savings The subsequent amendments to the

route planning are carried out in a matter of

minutes The ECDIS software takes care of

checking for dangers to navigation

automati-cally, provided a vector chart is used

Charts can be updated quickly and accurately saving navigators’ time to making the correc-tions and avoiding errors in the process Also, NAVTEX messages are automatically scan-ned for position information and a NAVTEX symbol appears in the referenced position al-lowing the navigators quick access to safety critical information without having to go through a manual plotting procedure.”

The overall conclusion reached by the A.P

Moller Group is that ECDIS will increase the safety of navigation significantly

Troms Fylkes Dampskibsselskab a/s

Troms Fylkes Dampskibsselskab a/s, which operates large passenger vessels along the Norwegian coast, has chosen to equip all vessels with ECDIS for reasons similar to those of the A.P Moller Group

This type of navigation is very demanding, especially during the long winter season, because it takes place mainly along the Nor-wegian coast and in and out of harbours through the archipelagos and the narrow fjords and sounds

Troms Fylkes Dampskibsselskab has used Electronic Chart Systems since 1992 and now uses ECDIS The experience gained is

a significant increase in the confidence of the bridge team Complicated navigational situations are handled calmly as the ECDIS gives the information required to identify fixed and floating aids to navigation, skerries and small islands and distinguishes such items from other ships on the radar which combined with track steering is still the main navigational tool

One glance at the ECDIS confirms the ship’s immediate position In the pre-ECDIS days, Captain Harrod Widding, Senior Captain in Troms Fylkes Dampskibsselskab, often had

to sail past ports along the route during win-ter because sea clutwin-ter from the confused sea, the swell pattern in the archipelago and clut-ter from snow completely obscured the ra-dar picture

The availability of ECDIS on board has sig-nificantly increased the regularity of port visits, especially during the cold season Captain Widding’s advice to operators of passenger ships in the Baltic Sea, which has many similarities with the Norwegian Coast

in many areas, is to switch to ECDIS as quickly as possible

The Royal Danish Navy

In late 2000 the Royal Danish Navy decided

to go for a full ECDIS implementation on all ships The ECDIS policy of the navy is

in short:

1. Full ECDIS implementation

2. All navigation sensors to be fully inter-faced via a navigation computer

3. No more paper charts

4. Ships’ bridges to be remodelled

5. All navigational officers to receive ECDIS training

The Navy particularly emphasizes the train-ing aspects, as navigattrain-ing with ECDIS is seen

as a completely new way of navigating

“ECDIS cannot be implemented safely if you think you are just performing the same tasks

on a screen Then you have not understood what ECDIS really is!”, says Commander Carsten Reiff, a key figure in the Royal Dan-ish Navy’s ECDIS implementation process Another key element is the decision to re-model the bridges during the installation

In December 2001, the A.P Moller Group decided to retrofit 160 vessels with ECDIS

Practical experiences

process in order to serve two main

pur-poses Firstly, to put the navigator and the

ECDIS in the best possible place so that the

navigator has a good overview out of the

windows, secondly, to emphasize that the

change to ECDIS truly involves a new way

of navigating and that the ECDIS is not just

a new box to be tucked in where room can

be found

Extensive trials with a number of ECDIS

systems leading up to the tendering process

gave the following main reasons for the

de-cisions:

1. A unique en route management tool.

2. Easy to use

3. No paper charts - no time-consuming

corrections

4. Real-time information

5. Increased situation awareness/mental

surplus

6. Ability to work together with other

dig-ital databases

The very nature of naval operations with

fre-quent changes of route plans which,

espe-cially in Search and Rescue operations, take

place in the worst possible weather, calls for

the best possible decision support system

also on the ship’s bridge ECDIS is exactly

the system that the Navy’s navigators have

been looking for

The Navy also experiences near-misses and

groundings as commanding officers drive

their ships at high speed through shallow and

confined waterways when training crews

The Navy expects to see a marked decrease

in such incidents following the

implementa-tion of ECDIS, which is scheduled for

com-pletion in 2003

Seatrans

Seatrans can be counted among ECDIS

pio-neers, participating in the very first trials with

Electronic Chart Systems in the late 1980s

Seatrans’ main area of operations are along

the Norwegian coast, in the Baltic Sea and

European ports, but the route Europe, South

America, the Gulf of Mexico and back to

Europe is also covered

From the first moment that the Electronic

Chart System was considered, it proved a

very good aid to navigation for experienced

navigators in coastal traffic The ability to

remove stress and tension during the frequent

periods with bad weather and poor visibility especially was highly appreciated by navi-gators - to such a degree that today naviga-tors almost insist that an Electronic Chart System is carried

Director Knut Skaar from Seatrans fully agrees with the experiences and evaluations made by Herodd Widding from Troms Fylkes Damskibsselskab Today Seatrans’

vessels are equipped with various types of Electronic Charts Systems and the company

is waiting for final confirmation from the regulatory authorities before type-approved ECDIS are fitted

The aim is to reduce the paper chart carriage

as much as possible As an example, the time spent on chart corrections on a chemical tanker on the Europe - South America - Gulf

of Mexico - Europe route corresponds to one navigator working full time

The requirement to keep all charts fully up

to date is being increasingly emphasized, especially by shippers of oil, chemicals etc

The shipping line must be able to document that all rules and regulations are observed, including the requirement that all charts car-ried are corrected and up to date

Seatrans has also experienced a significant drop in the accident rate Before Electronic Chart Systems were fitted, Seatrans experi-enced at least one serious grounding per year

Today, groundings are rare, though they do occur In one particular case a grounding occurred, fortunately only on a sand bar, because the navigator was only looking at the paper chart, where a sand bar had not

been marked with the usual red ink circle Knut Skaar is positive that a single glance at the Electronic Chart System would have shown the danger immediately However, the paper chart was the required basis for navi-gation, as the system was an Electronic Charts System and not an ECDIS

The new Chapter V of SOLAS, which en-ters into force on 1 July 2002, mentions ECDIS explicitly for the first time Regula-tion 19 states in paragraphs 1.2.4 and 1.2.5:

1.2.4 nautical charts and nautical publica-tions to plan and display the ship’s route for the intended voyage and to plot and monitor positions throughout the voyage; an Elec-tronic Chart Display and Information Sys-tem (ECDIS) may be accepted as meeting the chart carriage requirements of this subparagraph;

1.2.5 back up arrangements to meet the functional requirements of sub-paragraph 4,

if this function is partly or fully fulfilled by electronic means;*

* An appropriate folio of paper nautical charts may be used as a back-up arrange-ment for ECDIS Back-up arrangearrange-ments not inferior to resolution A.817(19), as amended, Recommendation of Performance Standards for Electronic Chart Display and Informa-tion Systems (ECDIS) are also acceptable

In order to make sure that there is no doubt about the status of ECDIS in Denmark, the Danish Maritime Authority will notify

Coastal navigation through archipelagos and narrow fjords and sounds can be very demanding.

Regulatory status

Trang 5

the IMO that Denmark accepts ECDIS

as fulfilling the chart carriage requirement

under the new SOLAS Chapter V The other

signatory states to the Helsinki Convention

will take similar steps

ECDIS was accepted only as an equivalence

under the SOLAS chapter V in force until 1

July 2002 Bearing this in mind, in October

2001 Denmark informed the IMO that ECDIS

would be accepted as an equivalence to

pa-per charts on Danish-flagged ships

Conse-quently, full ECDIS navigation has been

al-lowed in Danish waters from that time

These actions taken by the Danish Maritime

Authority are meant to underline the full

support for a rapid introduction of ECDIS

in ships operating in and out of the Baltic

Sea, but also on a worldwide basis The

de-cision of the Hydrographic Offices to lower

the recommended retail prices significantly

is a further step to encourage ship owners to

invest in ECDIS to the benefit of safety of

navigation and also, ultimately, to the

ben-efit of shareholders

A number of E.U.-funded research projects

dealing with various aspects of safety of

navigation have identified ECDIS as a

sys-tem that will have a considerable positive

impact on safety of navigation

THALASSES

Project objective: The assessment of the

socio-economic impacts of new

technologi-cal concepts in maritime transport, on the

human element

One of the findings of the report is:

“How-ever, the electronic chart or ECDIS

(Elec-tronic Chart Display and Information

Sys-tem) is going to become the most important

part of a future INS It is the ideal platform

to integrate (again, functionally and

opera-tionally) the important navigational sensor

information, the hydrographic data, the

plan-ning data and additional geographical

infor-mation to give the user all data on hand he

needs for a safe and efficient voyage.”

TECHNISECC

Project objective: Research and

demonstra-tion of conceptual (legal, procedural and

or-ganisational) tools and scenarios to be

inte-grated into VTS to provide “value added

services”

One of the findings of the report is:

“Fi-nally the presentation on Automatic

Infor-mation System (AIS) and on Electronic

Chart Display and Information System (ECDIS) put an emphasis on the role to be played in a very near future by both those systems, not only on board ships but also

on shore In this latter respect it may be expected that coupled with VTS equipment, AIS and ECDIS will considerably improve the quality of the traffic image both at tac-tical and strategic levels.”

SAFECO II

Project objective: The project objective was

to devise improved technologies and organi-sation for internal/external communication and to demonstrate the application of risk analysis methods to assess economical ben-efits and safety improvements of the devised solutions for total quality operations

One of the findings of the report is: “…The simplified and the advanced model estimates the same effect of a full implementation of Collision Avoidance Advisory Systems (CAAS) housed on ECDIS in relation to powered grounding accidents The probabil-ity for powered grounding, given a critical situation is estimated to be reduced with 15% The results from the two models differ significantly with respect to the reduction in the collision probability, given a critical situ-ation The “advanced” model results in a re-duction amounting to 10%, while the sim-plified model results in a reduction amount-ing to about 20%.”

See Note 3 below for the full texts of these reports

All in all, these research results clearly lead

to the same deductions as those already made

by the shipping companies mentioned above: ECDIS has a significant potential for increas-ing safety of navigation

References to ECDIS are also made in a

pro-posed EU directive following the Erika

ac-cident in 1999 In the communication from the Commission to the European Parliament the following is stated:

“Construction of the global navigation and positioning infrastructure is now a European Union priority through the GALILEO project This initiative will lead to a reliable and highly accurate service (3 metres on the high seas and 1 metre in port areas), which should serve as a reference for positioning systems applicable to ships in or near Com-munity waters Together with ECDIS, GALI-LEO offers a unique level of service in con-tributing to improved conditions of naviga-bility and safety.”

See Note 4 below for the full text of this Communication

All in all, this points towards an increasing awareness within the E.U system that imple-mentation of ECDIS in ships calling at Euro-pean ports and transiting EuroEuro-pean waters is

a way of increasing safety of navigation

The Erika incident, though caused by a

struc-tural fault rather than a navigational error, brought the significant environmental risks inherent in shipping to the notice of the E.U Current activities indicate that this aware-ness is still present and that efforts are

being made to avoid events with similar

impact on the environment at all costs

Any ship operator operating in the Baltic Sea

and in the approaches to the Baltic Sea can

with confidence start investing in ECDIS All

the Helsinki Convention signatories actively

support and encourage the use of ECDIS and

have committed themselves to provide the

ENCs needed for full ECDIS use

Substantial practical experience shows that there are numerous positive benefits from the use of ECDIS, most significantly the in-creased situation awareness But also the possibility of savings in fuel, of avoiding damage to ships due to collisions and groundings and of preventing lost sailing days due to repairs is evident

Finally, increased competitiveness due to the ability to operate confidently in adverse weather conditions should be mentioned

Now these benefits are also backed by re-search results One central finding in casu-alty investigations is that the human factor accounts for the overwhelming majority of accidents Hence, schemes that limit the ex-tent of human errors, for example by means

of better education and training, ECDIS sys-tems and other policies are the most likely risk reduction factors It is the authors’ hope that ship owners will follow the lead of the companies mentioned in this article to the benefit of all ■
