Supervisors' Days presentations Diving downloads (PDF)

First of all, we would like to thank you again for your participation in the Bluestream Supervisors’ Days 2022.

We have enjoyed the day and considered a successful event and we received a lot of quality feedback, which is highly appreciated. We look forward to a safe and successful diving season 2022, and look forward to have you on board and perhaps meet (again) on our vessels.

Rolf de Vries, Managing Director.

'Wrap up' and downloads

One of the points raised was  the request to receive a sort of summary of the day. For this reason we prepared this “wrap-up” of the day you participated in.

Please remember that this information is intended for your personal use only. Please do not distribute any further. You can find all the downloads at the bottom of this page.

Update Sessions

In the 1st session we presented an update on Bluestream and on QHSE.

The presented info can be found here:

Values Session

Bluestream has re-named its 'Core Values' with the aim to strengthening our organization and improving our market position to be the number 1 IRM service provider within our selected part of the Offshore Energy market.

The Core Values give direction to mutual cooperation and cooperation with our customers. The elaboration of the Core Values should also give direction to the safety culture and safety performance. During the Supervisor days we have shared, deepened and embedded the Core Values in daily practice. For this we have used the core values dialogue game. Feedback from the sessions told us that:

  • Bluestream is visibly improving when it comes to Safety Performance. There is always room for improvement though.
  • Current procedures are not always workable according to some Supervisors. Procedures could be more practical and shorter, making it more efficient and more workable.
  • There is a general need for more feedback from Safety matters.
  • Some projects are not always properly planned and/or change last minute. It creates an unnecessarily high workload and frustration for departments that have to perform the operational work (offshore).
Technical Sessions

In the afternoon we had 5 technical sessions:

Diving Manual

For the comming season an update of the Diving Manual is issued. An overview of the most significant changes is presented.

Underwater use of Chain Lever Hoists

In the second technical session we explained the investigations we did into the topic of underwater chain hoists.

During the investigation we noted that two 800kg chain lever hoists of William Hackett broke down. The cause of this brake down was thought to be overloading of the tackle, and this led to the advise to not use these small tackles. From the feedback during discussions it was clear that there were also other experiences with these tackles in situations that they were handy.  The request was to allow the use of 800kg tackles, which was acknowledged. The 800kg tackles will not be part of the Bluestream standard rigging containers, but on project basis the project manager can decide to have this size supplied to the worksite.

HPWJ and Precision Cleaning

The third technical session. For Precision Cleaning (e.g. cleaning of riser clamps for visual inspection in congested situations) Bluestream investigated the possibility to use a short lance in specific tasks.

This so called Precision Cleaning requires specific equipment that is described in the Work Instruction D-AIR-WIS-3006-02 “High Pressure Water Jetting up to 345bar Including Precision Cleaning”. If you want to use this method of Precision Cleaning this has to be agreed with the Project Manager on project basis.

Diving Medical Documentation

In the fourth session the new set of documentation on Diving Medical Documentation was explained and the referenced documents are now available on all diving sites.

COVID and Diving

In the last session, Bluestream’s medical advisor, Dr. Rob van Hulst explained the lates developments regarding COVID and diving.

In the presentation, Dr. Rob van Hulst presented us the latest “fitness  for dive” assessments and medical guidance. The latest DMAC 033 + 034 revision was explained, including the screening and examination tests of group 1, 2, 3 divers. It was recommended to have a regular examination including test with saturation measurement and pulmonary function. Also the recommendations were discussed for an asymptomatic diver with positive test results or mild symptoms scenario. Conclusion in this scenario were: one week no diving and regular examination. The scenario for divers with moderate/severe COVID-19 infection, results in extensive testing by pulmonary and cardiology specialist, with normally 3 months no diving (depending on X-ray and CT scan lungs).

For diver specific Covid-19 (infection) questions, please contact your Diving Physician. For general questions on Covid and diving the Crewing Department of Bluestream can be contacted.
