Heat shield deck for Ichthys Project

PcP. supplies their largest heat shield deck ever to a massive offshore project in the Indian Ocean.

It is the biggest oil and gas exploration company in Japan, INPEX, operating the offshore project called Ichthys. The field located approximately 889 km off the shore from Darwin in the Northwest of Australia can produce 8.9 million tons of liquefied natural gas a year.

The 80-m2 heat shield deck installed at the top of the flare tower on one of the largest semi-submersible rigs protects the lower decks and the rest of the construction against extreme heat.

The deck used also as service platform and access to the flame nozzles contributes to a safe working environment with the slip resistant LHD® surface.

Supplier to Samsung Heavy Industries

PcP. supplies other international offshore companies but the order is the first from Samsung Heavy Industries. The Korean company delivering the large 150 by 110 metre rig made the initial queries in December 2014.

Everything went fast as PcP. received the final order at the end of September 2015 and worked intensively with Korean observers on the side-line to produce the heat shield deck to ship only one month later. Normal time-to-delivery is 8 to 10 weeks.

PcP. succeeded and the deck dispatched from Vildbjerg to the Samsung shipyard in Geoje, South Korea and installed on the flare tower before deadline.

Safety gratings Type LHD®

The heat shield deck produced from PcP. safety gratings type LHD® in Alloy 800 material is a heat resistant, high-alloy, stainless product suitable in aggressive environments with high long-term temperatures.

The slip resistant LHD® grating surface of ø6 mm punched holes and ø6 mm drainage holes classifies as R11 slip resistance according to DIN 51130.

To weld in the Alloy 800 material requires special certified welders tested continuously during production. There are only a few in Denmark trained to weld in the material and outside welders supported PcP.s certified crew.

Verified by Lloyds Register

Lloyds Register verifies the LHD® grating functionality as heat shield deck in a testing environment using radiation heat showing temperatures around 100 degrees on the grating surface and only less than 65 degrees approximately 100 mm below the grating.

PcP. registers in Achilles JQS as official supplier to the Danish and Norwegian oil industry.

A potential for more orders

As newly certified supplier to Samsung Heavy Industries, PcP. hopes for more heat shield deck orders and other platforms to the industrial giant. That applies for both mesh gratings and safety gratings as well as other business areas. Aluminium scaffold planks is a product line in growth and Samsung Heavy Industries shows great interest in this particular product.

The Ichthys field expects to start production in third quarter of 2017 with 100.000 barrels of LNG a day at maximum operation.
