HELiMESH® is the World’s premium stainless steel safety net systems specifically designed for offshore helicopter landing deck perimeter structures.
Manufactured from 316 Stainless Steel Wire Cable & Tube Frame, HELiMESH® is extremely resistant to corrosion, even in the harshest offshore conditions.
Unlike other safety nets made from synthetic rope / webbing or PVC coated fencing mesh, HELiMES® will not burn or melt and will not deteriorate with exposure to UV rays or bird guano.
With up to 25 years service life HELiMESH® will dispense with repeated costly installations of inferior safety net systems and should outlast the life span of the facility.
HELiMES® safety net panels are light-weight, pre-fabricated in any shape or size ready to install, and can be installed without scaffolding. All materials and tools required for installation are supplied with delivery of the safety net panels.
The top 5 HELiMESH10® advantages are;
- With up to 10 years of service life the Helimesh system dispenses with repeated and costly installation of inferior safety net systems
- Because Helimesh10 is made only from 316 Stainless Steel it will not melt, burn or deteriorate with exposure to U.V. or bird guano
- The Helimesh “10 Year Service Life System” provides peace of mind to the operator proving ”Fit for Service” on an ongoing annual basis
- No “in-situ” drop testing is required offshore
- Quick removal for maintenance / access: As the Helimesh® system comprises individual custom-made panels it allows for quick removal and reinstallation should access be required to a particular segment of the helideck perimeter underside
And there are many more
Yes.
HELIMESH10® AND HELIMESH25® are two of only three safety net systems in the world which fully complies with British Civil Aviation Authority CAP437 Guideline and Oil and Gas U.K. “Helideck Perimeter Safety Nets – Issue 2”. Type testing as required by these documents was witnessed by D.N.V. – G.L. (Det Norske Veritas – Germanische Lloyd).
HELiMESH10® and HELiMESH25® are TWO out of only three helicopter perimeter safety netting which fully complies to the above mentioned standards
Rigorous type testing has been conducted in accordance with CAP437/O.G.U.K. guidelines. A drop test load of 295kg from 1m has been applied to the same HELiMESH® test panel with 10 repetitions without failure.
This far exceeds the O.G.U.K. required test load of 125kg.
We also have a Pull-through “Energy Testing” has also been conducted in the U.K. A result of 7.2kJ was achieved, exceeding the O.G.U.K. requirements of 6kJ.
A concentrated test load of 1000kg has been applied to a Helimesh test panel without failure. The total surface area footprint of dead weight to net surface was less than 0.1m². This test is not a requirement of any standard or guideline, rather it was only for our own research and development purposes.
Installation of the HELiMESH® helicopter perimeter safety net system is normally undertaken by the facility’s maintenance crew however a specialist installation crew can be provided if preferred or required.
Yes, HELiMESH® helicopter perimeter safety netting is made to ensure not only maximum safety, but also quick removal for maintenance / access if needed.
Because the HELiMESH system comprises individual custom-made panels, it allows for quick removal and reinstallation if access to a particular segment of the helideck perimeter underside should be required.
HELiMESH25®has a “Service Life Indicator panel” included as a standard on all Projects.
The panel is to be fixed in a readily accessible location that will be subjected to the same environmental elements as the installed Helimesh helideck perimeter structure safety net panels.
The system is designed so that the facility manager or operator every year can remove one piece of wire sample and send it to HELiMESH for testing. This way there are no costly on sight testing or shut downs of the helideck required.
HEliMESH® helicopter perimeter safety net systems are manufactured using only premium quality 316 Stainless Steel materials from the world’s most reputable steel mills.
HELiMESH® is supplied in specially designed, pre-fabricated panels up to 5.7m in length and 2.0m in width.
The largest HELiMESH® panel weighs under 20kg making manual handling and installation a relatively simple task.
Each new batch of materials is quarantined pending “Positive Material Identification” testing by our independent third-party metallurgical laboratories. All HELiMESH® helicopter perimeter safety netting is made by these materials only.
Yes.
Full materials traceability is provided on completion of each HELiMESH® project in M.D.R (Manufacturer’s Data Report) format.
The HELIMESH® Service Life Indicator Panel should be installed on or near by the HELiMESH helicopter perimeter safety net panels to asure that it gets the same inviromental influences as the safety net panels.

The client is free to choose between SSt and Copper ferrules. Most our clients choose SSt ferrules as they are made of the same 316 grade SSt as the wire and HELIMESH 25® tube frame. Only difference is the higher content of molybdenum 2.5 instead of 2.0 percent. Copper ferrules doesn’t corrote althoug made of dissimilar metal to stainless steel. The reason is that Copper has the ability to protect itself with a thin layer of Copper oxide.
Due to the long life span of HELiMESH 25® the cost per year is low compared to all other products. Down to half the yearly costs. On top of that the client gets the advantages of HELIMESH 25™ such as: Annual test regime, No down periods due to repeateded retrofitting, No costely annual in situ testing.
HELiMESH25 is very suitable for newbuilds and retrofits of constructions with a long life expectancy.
HELiMESH 10™ has lower initial costs than HELiMESH 25™. As the life span is shorter the costs per year is higher but the client still gets the advantages of a service life test system, longer service life than any other safety net system except from HELiMESH 25™ and of cause the benefits of a product consisting of AISI grade 316 Stainless steel instead of inferior materials like poly fibres, carbon steel, Sisal etc.
HELiMESH10 is very suitable for a limited budget or a construction with a limited life expectancy.

The Cost of HELiMESH® varies with the complexivity of the perimeter construction. That makes it hard to indicate a cost per m2. To help our clients we quote any RFQ whitin few days.
The lead time is normally 4-6 weeks for HELIMESH 25® and 3-4 weeks for HELIMESH 10® but we always try our best to help our clients as quickly as possible.
The reason we use insulation buffers between HELIMESH® and the perimeter structure is to prevent galvanic corrosion.
