HELIDECK FRICTION TEST - UK CAA, CAP 437

SL/HFT/C2 - v16.10.18

Services Rendered by:

“The landing area is a critical part of the helideck platform; keeping this safe for helicopter landingsis a key safety measure.”

Helideck Micro Grip Tester, recognized in UK CAA, CAP 437 is the world’s fi rst purpose built continuous friction measuring device designed specifi cally for testing Helidecks and Helicopter Landing Zones. Helideck MGT Testing it has been purpose built to cope with harsh offshore environments and for transportation too hard to reach facilities.

HELIDECK MICRO GRIP TESTER

Micro GripTester is the latest Helideck friction test equipment that meets all the strict requirements under UK CAA, CAP 437.

Helideck Friction Test carried out is based on UK CAA, CAP 437 which provides guidance on the periodicity of helideck friction testing. The helideck should be re-tested annually or when the condition of the deck suggests more frequent testing is appropriate.

FEDS ENGINEERING - HELITECH / CAP COMPLIANT SERVICES; a Member of British Helicopter Association (BHA); International Helideck Regulators Association (IHRA) and Helicopter Association International (HAI); specializes in Helideck Friction Testing on Offshore Installations and Vessels. With a team of trained Technicans, HFT is conducted using the latest friction measuring equipment. Our friction measuring devices and methodology meets all the strict requirements under UK CAA, CAP 437. Those of us involved in the offshore industry know more than most about the importance of safe working and risk management. With this in mind, regular helideck friction testing gives offshore installation operators the assurance needed to remove helideck landing nets. The fi rst assessment of a potential hazard, with the successful completion of a friction test, could be removed!

Extract from UK CAA, CAP 437 Standardsfor Offshore Helicopter Landing Areas

3.37 The landing area should present a non-slip surface for helicopter operations. The installation operator should ensure that the helideck is kept free from oil, grease, ice, snow, excessive surface water or any other contaminant (particularly guano) that could degrade the surface friction. Assurance should be provided to the helicopter operator that procedures are in place for elimination and removal of contaminants prior to helicopter movements.

3.38 The minimum average surface friction values that should be achieved are detailed in Table 2. The average surface friction values should be confirmed using a test method acceptable to the CAA – see paragraphs 3.39, 3.40 and 3.41.

3.39 For flat helidecks with a micro-texture finish (e.g. non-slip paint or grit-blasted finish), the helideck friction test method should normally comprise the following:

a survey of the entire helideck surface in two orthogonal directions to a resolution of not less than 1 m2;

use of a tester employing the braked wheel technique and a tyre made of the same material as helicopter tyres;

testing in the wet condition using a tester that is capable of controlling the wetness of the deck during testing, and

use of a tester which provides electronic data collection, storage and processing.

HELIDECK RECOATING APPLICATION In case required parametres of surface friction are not achieved, FEDS ENGINEERING W.L.L. can carry out Helideck recoating including the application of a Anti-Slip aggregate so as to meet the UKCAA, CAP437 friction Standard.
