Securing other equipment

This part covers other securing methods for equipment that was not coverd in other parts.

Securing valve handles

Valve handles and wheels

Best practice recommendations:

  • Valve wheels and handles must be fitted with secondary retention
  • Where possible, nuts and cotter pins should be used in the valve stem on stationary valve handles and wheels (nord- Lock and nyloc nuts can also be used where appropriate)
  •   On large handles and wheels, bolts and lock nuts should be used instead of cotter pins

  • When moveable handles or wheels are used, they should be secured

  • When not in use, handles and wheels should be stored in an appropriate, safe locatio

  • If Seeger rings are used for locking/securing, frequent inspections/maintenance should be carried out to check for corrosion and/or mechanical damage

  •  On wheels that are secured by a set screw only, replace the set screw with a through-bolt and lock nut

  • Safety wire with a lockable snap hook may be an alternative if the securing methods mentioned above cannot be used 

Securing chain operator valves

Valve handles and wheels

Best practice recommendations:

  • The valve wheel shall be attached to the valve stem with locked through-bolt connections, e.g. nyloc nuts and castle nuts with cotter pins
  • In cases where the chainwheel is installed on an existing valve wheel, the chainwheel must be fixed to the valve wheel with u-clamps fitted with secondary retention, e.g. nyloc lock nuts
  • If the chain guides are installed with a surface lock ring with clamping sleeves, the clamping sleeves should be replaced with bolts and lock nuts where possible. For chain guides designed with separate clamps, locked through-bolt connections must be used on the clamps
  • The valve shall be secured to the structure using correctly dimensioned safety wire and lockable connectors. in many cases it will be appropriate to attach the safety wire to the chain guide on the chainweel so that functionality is ensured (this presumes that the guide is sufficiently dimensioned and installed using locked bolt connections)
  • If it is not possible to attach the safety wire to the structure via the chain guides or another method without functionality being impaired, a swivel device for the attachment of securing devices must be installed. This should only be done by qualified personnel with experience of securing such equipment at height
  • For new installations, or when installing securing devices on existing equipment, an up-to-date user manual/maintenance instructions should be provided

Note: 
There are several different types and designs of chain-operated     valves available on the market, but the principles for securing these valves will be the same in most cases.
Chain-operated valves without adequate secondary retention can represent a great risk to the operator of the valve.
This is because these valves are often located at height, or in areas that are difficult to access

Lock on insulation cladding

Locks on insulation cladding

Best practice recommendations:

  • Insulation cladding must be securely fastened to prevent locks from loosening unintentionally
  • The locks shall be secured with secondary retention, either by using a bolt and lock nut or by inserting a stainless cotter pin through the securing holes in the locks, or similar
  • Maintenance routines must include inspection of the cladding to ensure that it remains in good condition at all times
Securing storage of gass cylinders

Storage and placement of gas cylinders

Best practice recommendations:

  •  All storing/placement of gas cylinders must be risk assessed
  • Gas cylinders must be stored, positioned and secured safely
  • Temporarily stored gas cylinders must be secured with chain or wire
  • Permanent storage racks must be equipped with securing brackets / clamps
  • The storing of gas cylinders must not obstruct the passage of personnel
Snatchblocks

Snatch blocks

Best practice recommendations:

  • Blocks must have two barriers in both the suspension and the shaft
  • A maintenance program must be established in accordance with the manufacturer’s user manual. it is a requirement that blocks, shackles and lifting lugs must be inspected at least every twelve months by a competent person. This must be documented
  • Blocks must be dismantled at the request of the competent person or in accordance with the manufacturer’s recommendations, and at least every five years
  • Snatch blocks and suspension shackles should preferably be marked with coloured tie wraps of the designated colour code for the year
Securing umbilical roller sheaves

Umbilical roller sheaves

Best practice recommendations:Umbi

  • An umbilical roller sheave must have a maintenance program and be subjected to testing and inspection at least every twelve months in accordance with the manufacturer’s instructions
  • Rollers must be secured with two independent barriers, e.g. through-bolts with lock nuts or cotter pins
  • An umbilical roller sheave must be used exclusively for the purpose for which it was intended, i.e. it is not permitted to use an umbilical roller sheave to suspend wires
  • The umbilical must be installed on deck and the support rollers reinstalled and secured
  • A user manual/maintenance instructions for the equipment must be available. The instructions must also cover the installation and maintenance of securing devices
  • Sheaves and suspension devices should preferably be marked with coloured tie wraps of the designated colour code for the year
Securing loop hoses

Loop hoses

Best practice recommendations:

  • The equipment manufacturer’s instructions for installation and the technical description must be followed
  • Clamps must be attached and securely fastened at the point where the hose is labelled “Attach safety clamp here”
  • Safety chains must be as short as possible and installed as close to the vertical as possible in order to prevent fall energy and pendulum effect
  • Securing devices for hoses must be designed to support the maximum loads generated by a burst hose
  • The required resistance to wear and tear, chemicals, heat and uv radiation must also be documented
  • The securing system for hoses must be documented and traceable
  • The securing devices should be checked and labelled in accordance with the norm for lifting appliances
  • In addition to correct instructions for installation, the user manual/maintenance instructions should contain guidelines for necessary maintenance and inspection of the securing devices
  • The use of Hammerlok chain connectors in securing devices should be avoided, since these are not suitable for static loads and offer poor corrosion resistance
Securing sings

Sings

Best practice recommendations:

  • Signs, brackets and frames for signs must always be securely attached. The frames should be made of metal
  • Where the underlying material permits, sign frames should be attached using through-bolts with lock nuts
  • Fasteners used for attachment to brackets and structures must be fitted with secondary retention
  • Painted or adhesive identification tags are recommended for the identification of piping systems. On hot surfaces, identification tags should be attached using plastic- coated steel bands.
Securing racks and storage

Racks and storage

Best practice recommendations:

  • Racks and storage units must be secured/fastened to permanent structures in an appropriate and durable manner
  • Ensure that storage in all areas is permitted in a controlled manner with respect to the type of goods, duration, storage area and housekeeping
  • Storage must not obstruct accessibility or evacuation of the module
  • Ensure that the stored materials do not obstruct access to emergency equipment
  • Storage racks and storage areas must be designed to ensure that equipment cannot accidentally drop to lower levels
  • The heaviest equipment should be stored at the bottom
  • If storage at height is necessary, permanently installed equipment containers with lockable, hinged lids shall be used
  • On mobile units, temporary storage spaces/racks must be appropriately secured
  • Shelves shall be equipped with raised edges to prevent equipment from sliding off
  • Materials must not be stored on top of cabinets/racks
Securing Derrick evactuation equipment

Derrick evacuation equipment

Best practice recommendations:

  •  Equipment must be protected from wear and harsh environments.
  • Equipment should be stored in a cabinet/locker/bag in order to protect it from uv radiation and weather conditions
  • The riding belt or harness must be attached to the evacuation block or to the guide line where appropriate.
  • Safe access to and use of the equipment must be ensured.
  • Evacuation blocks, guide lines, attachment points, couplings and shackles are defined as evacuation equipment/fall arrest devices, and must be checked, certified and labelled accordingly.
  • Evacuation blocks must be CE-marked
  • Anchor points for suspension must be able to support at least 10kn.
  • The equipment must be checked at least every 12 months by a competent person, and shall be labelled with the next inspection date.
