Frequently asked questions about S-VDR

General

Should a "fixed" or "float-free" data storage capsule be used?

There is no Type Approved float-free solution currently available and there are varying views on which solution would be most easily retrieved. Indications are that both options are similarly priced.

To what degree does the choice of S-VDR depend on the make of the existing bridge equipment?

The technical specification of the S-VDR has been determined with the express aim of maximising the connectivity with other equipments. The choice of S-VDR can therefore be based with emphasis on the functionality of the particular S-VDR and the worldwide service support available.

What benefits can be expected from fitting S-VDR?

The operational experience gained from ships equipped with VDR has been well recorded over many years and in summary confirm the positive benefits particularly relating to accident investigation, training and monitoring, assessment of response to safety and environment emergencies, promoting best practice and accident prevention and reduction in insurance losses.

VDRs have also proved invaluable to shipowners as a management tool in analysing hazardous incidents and bridge team procedures. Additionally VDR recordings have provided irrefutable evidence in pollution incidents as well as providing a indisputable record of a Master's action. There have also been a number of instances where disclosure of VDR recordings precluded court actions with the subsequent significant savings in costs.

Can the recorded data be accessed remotely?

Remote access to data is not a requirement of the IMO but a limited number of manufacturers do offer this facility as an option. Kelvin Hughes “MantaDigital™ S-VDR” has the capability of being interrogating through GSM or satellite communications from the shore. This optional feature also allows on board technical problems to be diagnosed remotely, enabling spares or other support to be arranged in advance of the ship’s arrival in port.

What time period can be recorded?

The IMO requires a minimum of 12 hours recording but most manufacturers provide larger storage options often with removable media which may be used as a management and training tool. This latter option, sometimes referred to as a “white-box”, has found favour in the past where ships’ staff are able to retain a record of an event without disturbing the main (mandatory) data contained within the S-VDR.

How is the performance of the equipment monitored?

The IMO Performance Standard for S-VDR requires a built in test facility to be provided to allow for continuous monitoring of the performance of the equipment. An audible and visual alarm is automatically triggered in the event of a malfunction of the S-VDR.

How and where can the data be replayed?

Playback facilities are offered by all manufacturers, usually free of charge, as part of the S-VDR package. This enables incident analysis to be undertaken on board, ashore and in a Court of Law.

Installation

Who can carry out annual performance checks?

All maintenance, service and commissioning of S-VDR equipments must be carried out by engineers approved by the Manufacturer concerned. This may be delegated to a nominated service agent although some manufacturers, such as Kelvin Hughes, have the added advantage of a well established and proven worldwide support network with factory trained engineers located in key ports.

Can an S-VDR be installed whilst the vessel is in service?

In the majority of cases, the installation of an S-VDR can be carried out whilst the vessel is in service. The majority of the work centres around the running of cables for microphones on the bridge and the collection of data from a number of sources. The only restriction on installing during service is when it may become necessary to weld fixings or cut cable penetrations (hot-work) on vessels carrying hazardous cargo. e.g. Tankers and gas carriers.

How long does installation & commissioning take?

A typical installation, which would include cable running, mounting of units, termination of cables and commissioning is estimated to take 5/7 days with two engineers. If preparatory work is completed in advance with the running of cables and provision of foundations for units then termination and commissioning is estimated to take 3 days.

Legislation

How will compliance be enforced and monitored?

Compliance with Carriage Requirements for S-VDR will be enforced by the appropriate Flag State and Port Control authorities may also prevent vessels from operating who do not have a suitably working S-VDR.

What Type Approval or Classification Certification is necessary?

All S-VDR equipments fitted to satisfy IMO requirements must be Type Approved.

Kelvin Hughes is the first to receive Type Approval for its MantaDigital™ S-VDR through Qinetiq, the UK government nominated testing organisation. Other manufacturers are following and submitting equipment for test to Qinetiq and other test organisations, including the German testing house, BSH. Individual Classification Societies can endorse Type Approved equipments by reference to the results obtained by the test organisation.

What are the requirements?

IMO through MSC at its 79th session in December 2004 agreed the following amendment to SOLAS Chapter V Regulation 20

To assist in casualty investigations, cargo ships, when engaged on international voyages, shall be fitted with a VDR which may be a simplified voyage data recorder (S-VDR) as follows:

  1. in the case of cargo ships of 20,000 gross tonnage and upwards constructed before 1 July 2002, at the first scheduled dry-docking after 1 July 2006 but not later than 1 July 2009;
  2. in the case of cargo ships of 3,000 gross tonnage and upwards but less than 20,000 gross tonnage constructed before 1 July 2002, at the first scheduled dry-docking after 1 July 2007 but not later than 1 July 2010; and
  3. Administrations may exempt cargo ships from the application of the requirements of sub-paragraphs 1 and 2 when such ships will be taken permanently out of service within two years after the implementation date specified in sub-paragraphs 1 and 2 above.

To what types of vessels does the Carriage Requirement apply?

All vessels involved in international trade over 3,000 tons gross tonnage will be affected by the requirement (except where an exemption is granted by the flag state)

Legal

Will fitting S-VDR impact on insurance premiums?

A Marine Underwriter's Perspective

There is no doubt that the shipping industry can learn a lot from the world of Aviation and this is certainly a point of view held by eminent parsonages such as Lord Carver and Lord Donaldson. The lessons learnt from, “black-box” information following air crashes has obviously done a lot to improve the safety in this industry.

The lessons learnt have also given the operators data to enable them to reduce the human element proportion of air disasters. So how can any one argue against a similar initiative in the Marine world?

As underwriters we can see the potential advantages that VDRs will bring in reducing the insurance risks.

There is always room for improvement, and, as lessons are learned from VDR playbacks ship operators will be able to respond with meaningful loss prevention actions which will have a beneficial effect on their insurance results.

VDRs will also provide a reliable and unbiased witness at times of accidents involving other parties. Here again VDR evidence will do a lot to reduce legal costs and the sterile wrangles about who is to blame.

Is the recorded data recognised as legal evidence?

Yes - extensively, there have been a number of instances already experienced where the disclosure of the existence of VDR recorded data has precluded court action. Clearly there is an advantage in the situations where systems are installed with the additional removable memory, sometimes referred to as the "white-box".

In the event of an incident - who owns the recording?

"Ownership and recovery" (Abstracts of IMO FSI Sub - Committee 9)

Recovery of VDR

In the case of non-catastrophic accident recovery of the memory should be straightforward. This action will have to be taken soon after the accident to best preserve the relevant evidence for use by both the investigator and the ship owner. As the investigator is very unlikely to be in a position to instigate this action soon enough after the accident, the owner must be responsible, through its on-board standing orders, for ensuring the timely preservation of this evidence in this circumstance.

In the case of abandonment of a vessel during an emergency, masters should be instructed, where time and other responsibilities permit, to recover the memory and remove it to a place of safety and to preserve it until it can be passed to the investigator.

In the case of a catastrophic accident, where a vessel has sunk and the data has not been retrieved prior to abandonment, a decision will need to be taken by the Flag State in consultation with any other substantially interested states on the viability of recovering the protective capsule against the potential use of the information. If it is decided to recover the capsule the investigator should be responsible for its recovery. The possibility of the capsule having sustained damage must be considered and specialist expertise will be required to ensure the best chance of recovering and preserving the evidence. In addition the assistance and co-operation of the owners, insurers and the manufacturers of the VDR and those of the protective capsule may be required.

Custody of VDR/data

In all circumstances, during the course of an investigation, the investigator should have custody of the original VDR data, perhaps in the form of the whole or part(s) of the VDR itself, in the same way as he has custody of other records or evidence under the Code for the Investigation of Marine Casualties and Incidents.

Ownership of VDR/data

The ship owner will, in all circumstances and at all times, own the VDR and its data.

Read-out of VDR/data

In all circumstances the responsibility to arrange down loading and read-out of the data from the recovered memory in whatever form should, in the first instance, be undertaken by the investigator who should keep the ship owner fully informed. Additionally, especially in the case of a catastrophic accident where the memory may have sustained damage, the assistance of specialist expertise may be required to ensure the best chance of success.

Access to the data

Although the investigator will have custody of the original VDR memory in whatever form for the duration of the investigation, a copy of the data must be provided to the ship owner in all circumstances.

Further access to the data will be governed by the applicable domestic legislation of the flat state, coastal state and the lead investigating state as appropriate and the guidelines given in the Code for the Investigation of Marine Casualties and Incidents.
