    Influence of oxygen purity in underwater cutting

    Whether on the surface or underwater, to burn and turn into iron oxide, a metal (iron) needs some supply of pure oxygen. In order to obtain a maximum efficiency, most manufacturers of cutting material as well as some cutting manual’s advice to use an oxygen purity of at least 99, 5 %, and predict that it is impossible to cut as soon as the purity of oxygen becomes equal to or less than 95%. Is it a myth or a reality?

    The Little Story of the Underwater Cutting

    Since under water Cutting exists it has always interested not only the general public who sometimes wonders how it is possible to burn something under water but also most commercial divers who generally like to practice this particular discipline. Currently the divers have at their disposal a variety of tools and methods to accomplish this type of mission, but as you can imagine this has not always been the case. I therefore propose you to follow me through these pages and discover the story of these wonderful tools

    Delta P in Diving - Risks and Prevention

    According to a recent study, accidents due to a delta P (differential pressure) are the single most common cause of fatal accidents in the commercial diving sector. For the most part, commercial divers are aware of this phenomenon, but unfortunately many of them seem to underestimate this risk. No less than 127 such accidents occurred between 1975 and the end of 2014 and delta P incidents are usually fatalities. All sectors of commercial diving have exposure to delta P, but the civil engineering divers (inshore), pay the highest price.
     
    Make no mistake - accidents due to differential pressure are not “fate” or “bad luck” and in most cases the accidents that have occurred could have been avoided. This short guide is intended to highlight what delta P is and the ways to protect divers from it.

    UK Diving Contractors List

    Here it is for anyone
     
    Full list of diving contractors working or eligible to work in the UK.
     
    Before anyone asks, I don’t have, nor do I intend to undertake making up any lists for other countries either. This list is hard enough to keep track of with companies ceasing trading, dissolving, liquidating or going bankrupt.
     
    Anyone know of a UK company I have missed let me know.
     
    There were 6 companies that were listed previously which are listed as Active with company’s house. They have no web site but the phone number is active and I couldn't get any answer after several calls which leads to thinking they are not seriously plying for diving work.
     
    These are
    Aquatech Marine Ltd of Fort William
    Fort Subsea Limited of Methilhill Leven Fife
    P Brawn Diving & Engineering Services of Stromness Orkney Islands
    Rowen Welding and Underwater Construction Ltd of Newcastle Under Lyme Staffordshire
    Tobermory Shellfish & Diving Services of Isle of Mull
    Wester Ross Diving Services Ltd of Lochcarron Highland
     
    If you know they are still operating let me know and I’ll amend the list

    Tax Information for those working in the UK

    The information contained in this file is for UK residents or those engaged working in the UK who pay UK tax containing information on,
    1. Divers and diving supervisors allowances before tax for offshore and inland inshore divers working under the CIS scheme including a copy of an employment contract for your partner or spouse
    2. Divers and diving supervisors capital allowances for offshore and inland inshore divers working under the CIS scheme
    3. Claiming for diver training and trade courses
    4. Idiots guide to SED
    5. Claiming a National Insurance rebate for work outside the UK and Norway
     
    As an add on, the file contains account packages to calculate the tax owed on your income for the new tax year of 2011- 2012:
    1. Divers and diving supervisors working offshore
    2. Divers and diving supervisors working under CIS
    3. SED calculator
    4. NI rebate calculator
    5. Inland Inshore CIS simple time sheet.
    All the spreadsheets in this file are protected to save the calculations.
    But they are not password protected so you can unprotect the file and amend the sheet to suit if you wish
     
    You may not need the whole package, but it is too complicated to separate so it is offered as a single unit.
     
    A small part of the package will save you money and if you are a diver or diving supervisor working in the UK the $10 cost is tax deductible.
     
    You could go to an accountant for the same advice and that would cost a lot more.
     
    The money goes to the upkeep of this site not the author.
