Approved Diving System Inspector scheme progresses

IMCA has published two new Guidance documents to support the forthcoming Accredited Diving System Inspector (ADSI) scheme. Planned for release later in 2023, the scheme will become the industry-recognised professional accreditation for diving system inspectors. It also aims to improve the quality, professionalism and credibility of DESIGN diving system inspections – IMCA’s reference document for the equipment and set up required for safe diving operations. This will provide assurance that diving systems that have undergone a DESIGN inspection by an ADSI are both safe and fit for purpose. The ADSI scheme will be open to a range of personnel including

New diving guidance on subsea power cables

New guidance from IMCA has been published to support the increase in diving work related to offshore renewable energy projects and subsea power cables. While subsea power cables have been in use for many decades to provide electrical power to islands, offshore installations, and subsea plant and equipment, the demand for subsea power cables has significantly increased in recent years owing to a massive growth in offshore wind farm construction projects. IMCA D 079 Subsea Power Cables is intended to assist IMCA Members in the identification and mitigation of potential risks when planning their diving projects on, or in connection

Diving certificate forgeries discovered

During a routine review of recent diving contractor Membership applications, IMCA uncovered forgeries of UK HSE diving certificates, IMCA DMT certificates, and CSWIP 3.1U certificates. The certificates had several inconsistencies, including false serial numbers and duration validity irregularities, which led our experienced team of technical advisers to suspect their authenticity. IMCA’s concerns were brought to the attention of the UK’s Health and Safety Executive (HSE) who confirmed that the submitted certificates bearing the Executive’s logo were, in fact, forged. As part of an IMCA diving contractor Membership application, companies are required to provide evidence that they can assemble an IMCA

New CPD requirements for Dutch air diving supervisors

Following negotiations with authorities in the Netherlands, IMCA has reached agreement for the use of Continuing Professional Development (CPD) to recognise Dutch NDC-CI offshore diving supervisor certificates. Last year the UK’s Health & Safety Executive (HSE) removed requirements for supervisors operating in UK waters to undertake an exam, and the examination was subsequently withdrawn. As a result, the previous route to certification – where Dutch candidates were able to convert their certificate by sitting the exam – is no longer available. The changes mean NDC-CI certificate holders are now required to complete CPD to the same standard as IMCA-certified diving

New guidelines for DP diving and umbilical management

IMCA is pleased to announce the publication of IMCA D 010 Rev. 4 Diving Operations from Vessels Operating in a Dynamically Positioned Mode and IMCA D 078 Guidance on Diving Umbilical Management. The two documents are closely related, and to conduct Dynamic Positioning (DP) diving operations safely, it is essential to follow the guidance contained in both publications. All sections of IMCA D 010 were closely reviewed during the revision process and the guidance now represents the latest industry thinking on the safe and effective management of DP diving projects.

Guidance on shallow water diving operations updated in Code of Practice

IMCA is pleased to share Revision three of its flagship guidance document on diving operations, the IMCA International Code of Practice for Offshore Diving (IMCA D 014). The revised guidance will be particularly helpful to those currently managing shallow water diving operations in the offshore wind industry.

IMCA Diving Manager Bryan McGlinchy said: “Shallow water diving operations are sometimes undertaken

New IMCA Diving guidance on lost bell emergencies

IMCA has published new guidance on lost bell emergencies. IMCA D 077 – Guidance on prevention and mitigation of lost bell emergencies draw together the Association’s key advice on the subject into a single up-to-date guidance document. A potential significant risk when using closed diving bells is that the diving bell and its divers cannot be recovered, either because the main lift wire, secondary lift wire(s) and main umbilical are severed, or because the bell is trapped. Such an incident is referred to as a ‘lost bell’ if supplies of breathing gas or heating from the surface are lost.It is

Designed to enable supervisors to easily demonstrate that appropriate CPD has been completed, it is available on both Apple and Android phones and tablet devices. For those working at sea, or with poor data connections, the content including interactive tutorials can be downloaded to be completed offline.Commenting on its publication, Bryan McGlinchy, Diving Manager at IMCA, said: “We’re delighted to share

Guidance on the provision, acceptance and handling of breathing gases for diving

A newly published document – ‘Guidance on the provision, acceptance and handling of breathing gases for diving’ IMCA D 075 – from the International Marine Contractors Association (IMCA) aims to raise awareness of the issues that industry has faced when procuring breathing gases used for diving. As Bill Chilton, IMCA Technical Adviser – Diving, explained “Over the years there have been a number of incidents where divers have been injured or even killed during the course of their work after being supplied with incorrect breathing mixtures.  Following recent incidents of this nature IMCA was asked by industry to assist in

Guidance on protecting divers during underwater excavations

A newly published document – ‘Guidance on Underwater Excavation Works Involving Divers’ IMCA D 074 – from the International Marine Contractors Association (IMCA) aims to raise awareness of the hazards associated with subsea excavation works and, in particular, the significant risks to divers who engage in such work. As Bill Chilton, IMCA Technical Adviser – Diving, explained “Over the years there have been many incidents where divers have been trapped, injured, or killed either by direct contact with excavation equipment or by collapses while working inside various types of excavations below seabed level. Recent accidents have highlighted the need for

Instructions on how to use the logbook are set out in explanatory notes. There are separate sections for recording details of examinations and certifications held; training courses attended; and individual MEO field

Importance of COVID-19 Vaccination to the Offshore Diving Community Stressed

The Diving Medical Advisory Committee (DMAC) has issued new a position statement on the importance of COVID-19 vaccination for offshore divers. DMAC’s statement at makes it clear that the known risks of COVID-19 illness and its related, possibly severe complications, far outweigh the potential risks of having an extremely rare serious adverse reaction to vaccination. DMAC strongly recommends that offshore divers and diving personnel follow national recommendations for primary vaccinations and booster doses; and that: “diving contractors wishing to control risks as far as reasonably practicable should take account of this, within the applicable legislative framework”. IMCA’s CEO Allen
