Auditing Service

MW group offers a broad range of IMCA auditing services for Diving spreads. We utilise a team of highly recommended competent Auditors with many years of experience in this field, to provide cost effective and timely delivery to our clients.

OUR IMCA DESIGN GUIDELINE AUDITS INCLUDE:

  • IMCA D023 – DESIGN for Surface Oriented (Air) Diving Systems
  • IMCA D024 – DESIGN for Saturation (Bell) Diving Systems
  • IMCA D037 – DESIGN for Surface Supplied Mixed Gas Diving Systems
  • IMCA D040 – DESIGN for Mobile/Portable Surface Supplied Systems
  • IMCA R006 – ROV Systems

“We provide an objective as oppose to subjective audit, combined with pragmatic as oppose to pedantic view, carried out by auditors who are knowledgeable in both diving and engineering disciplines”.

OBJECTIVES

Standard and Requirements

Our auditors are professionals, without affiliations to diving or ROV contractors and cover the intrinsic IMCA competency levels 1, 2, 3 & 4, and are trained in Safety Management Systems audits registered under the International Register of Certified Auditors (IRCA). We are committed to providing continuous support from project management, through mobilisation to operational phase’s while ensuring the safety and compliance with requirements from country of jurisdiction, Clients Terms as well as code of practices of classification societies.

FMEA AND FMEACA AUDITS

Saturation and Mixed/NitrOx/Air systems must be supported with a current Failure Mode Effect Analysis (FMEA) document and all new diving systems shall be designed, fabricated and maintained in class.

FMEA VERSUS FMEACA

FMEA is a requirement under class and is system focussed as opposed to a full FMEACA which is sub system focussed and consequently more detailed. What an FMEA can therefore fail to identify are specific component interactions and their failure modes/consequences, for example diving systems, power management systems, cranes J lay systems, etc.

The expertise required to review and interpret the results of FMEACA/FMEAs for vessel deployment equipment and systems is provided with qualified, competent auditors who have a detailed theoretical and practical experience for system being audited.

Saturation and Mixed/NitrOx/Air systems must be supported with a current Failure Mode Effect Analysis (FMEA) document and all new diving systems shall be designed, fabricated and maintained in class.

FAILURE MODE, EFFECTS AND CRITICALITY ANALYSIS

Where operations are planned that involve complex vessel systems it is recommended that an appropriate Failure Mode, Effects and Criticality Analysis (FMEACA) is in place.

Some vessel systems where a FMEACA is likely to be appropriate are:

  • Vertical and horizontal pipe or umbilical tensioner lay systems
  • Vessel Saturation and HeliOx /NitrOx /Air Systems used for the deployment of divers.
  • Subsea habitats
FMEACA OBJECTIVES

The objective of the FMEACA process is to identify the possible consequences of any potential system failure modes on:

  • The safety of personnel
  • Any environmental impact
  • The potential for plant or equipment damage
  • Impact to the project programme

Whilst the safety of personnel is usually well catered for under the standard risk assessment processes, it should be noted that an effective FMEACA may actually remove potentially difficult repair activities or identify more suitable alternative courses of action should a failure occur.

Saturation and Mixed/NitrOx/Air systems must be supported with a current Failure Mode Effect Analysis (FMEA) document and all new diving systems shall be designed, fabricated and maintained in class.

FMEACA BENEFITS

The output from the FMEACA process provides practical engineering and planning support to projected work scopes. As a minimum, it will sharpen the focus on failure criticality and improve the project’s ability to plan appropriately and it is not unusual for a FMEACA to significantly change a project’s contingency or spares policies.

THE KEY BENEFITS ARE
  • Improved operational awareness through identification of the most failure critical aspects of the work programme
  • Accurate identification of programme contingency options and enhanced contingency planning
  • Improved and more failure-specific spares management policy
FMEACA PROCESS

The FMEACA process can be carried out at system, subsystem or component level. Generally it is appropriate to go to subsystem and major component level for diving project activities due to vessel costs and project impact.
FMEACA’s should be carried out as a formalised process. An outline of this process is as follows:

  • Identify the systems or subsystems involved
  • Identify the failure modes
  • Identify the possible failure causes (this may involve a review at component level)
  • Carry out probability and severity reviews (this may take the form of discussion notes)
  • Using probability and severity ratings produce a criticality rating
  • Develop mitigations as appropriate
  • Carry out the mitigation recommendations
  • Publish the results to ensure team awareness
THERMAL ENVIRONMENTAL TESTING OF HYPERBARIC CHAMBERS

We have ACCREDITED methods, personnel and equipment for compliance testing thermal trial to prove the Hyperbaric Evacuation Systems (HES)/Hyperbaric Rescue Facility (HRF)/Hyperbaric Rescue Craft (HRC)/ and Self Propelled Hyperbaric Rescue Craft (SPHRC), are fundamentally safe and in keeping with the associated importance placed on health and safety.

FMEACA BENEFITS

Testing is in accordance using the relevant technical information, guides, procedures and standards from the following:

  • Australian Standard AS2853 (1986) Enclosures- Temperature Controlled-Performance Testing and grading.
  • MW Group Pte Ltd in house procedures MW 005-1.2. Revision 3.
  • IMCA D 02/06- Information Note: “The Evaluation and Testing of the Environment Control of hyperbaric Evacuation Systems.”
  • IMCA D 02/06- Technical Note: “The Evaluation and Testing of the Environment Control of hyperbaric Evacuation Systems.”
  • Institute Biomedical & Bimolecular Sciences. University of Portsmouth. “The Estimation of the Metabolic Production of carbon Dioxide in Hyperbaric Evacuation System.”

Furthermore we carry out all thermal work in compliance with International Laboratory Accreditation Cooperation (ILAC, ISO 17025 incorporating ISO 9001) and US Department of Navy NAVSEA this will be issued in our independent report covering:

  • Base Line Test
  • Hypothermia
  • Hyperthermia
  • Hyperthermia Full Diving Complement
  • Assessment of maximum Cooling capacity
  • Cooling System Failure
  • Carbon dioxide Scrubber Performance Test

The above ensures added value and international acceptance for submission to interested parties.

THE KEY BENEFITS ARE
  • Improved operational awareness through identification of the most failure critical aspects of the work programme
  • Accurate identification of programme contingency options and enhanced contingency planning
  • Improved and more failure-specific spares management policy
