About the Project


Locker Heatshielding Ltd were contacted by Technip Oceania in 2008 to assist with protection of flare gas supply pipework and flare air ducting located at the Kupe Gas onshore terminal. These flares are positioned in a specially designed burn pit to prevent damage to any surrounding infrastructure.

Due to the horizontal orientation of the flare tips, the Heatshields had to provide full protection to both the equipment and support structure, as there could be a tendency for the flares to blow back in the direction of the Heatshield wall. The shields also needed to fit in close proximity to the flare tip piping without affecting performance.

The Locker Single Skin Ladder was selected, as it provides 150mm standoff from the supporting structure and greater protection against the flare and radiant heat produced.

A key benefit of Locker Heatshields is that they can easily be shaped to fit around practically any shape and size, providing greater flexibility for challenging onshore and offshore projects such as this.

The Kupe natural gas field is located in the Tasman Sea, 30km off the coast of Manaia in Taranaki, New Zealand. The field was discovered in 1986 and is located in 35m of water. The production facility comprises an unmanned offshore platform, a 30km single 3 phase pipeline to shore and an onshore production station.

About the Project


Total E & P Nigeria contacted Locker in August 2008 regarding a problem with the AMT2 flare deck.

The Original Flare Deck had no Heatshield protection and the supporting steelwork was damaged by the elevated temperatures present. Numerous interim modifications were employed in an attempt to strengthen the structure but Locker Flare Deck protection was agreed as the best solution.

The replacement flare deck provided unique challenges in that the panels had to be shaped around the existing structure, and modifications undertaken over the years meant incorporation of a number of complex shapes.

These panels were designed, fabricated and delivered to a tight budget and delivery schedule, and subsequently installed within the specified period. Successful fulfilment of complex requirements strengthened our relationship with Total E&P in the West African region and further demonstrated our ability to meet any challenge asked of us.

About the Project


Jacobs Engineering contacted Locker Heatshielding in June 2008 regarding a project at the Ineos Grangemouth processing plant. Recent expansion of the plant meant that a 25m escape walkway had to traverse a flare exclusion zone, passing through two separate flare stacks to the accommodation block and muster points beyond.

The radiant heat present within this zone was specified as 6.3kW/m², and as the maximum exposure for personnel making emergency access through this area is limited to 30 seconds, it was imperative that a complete protective solution for any personnel required to access this route was provided.

Locker Mini and Ladder Heatshields reduce the radiant heat by in excess of 80% at a distance of 300mm behind the front face, so by installing the Heatshields on all three exposed sides of the escape route, the radiant heat would be reduced to around 1.3kW/m². This is below the threshold for the maximum radiant heat for continuous exposure.

Typically Locker would specify Ladder shields for the sides of the walkway as this incorporates an internal personnel protection mesh which prevents contact with the outer ‘Hot’ Radiant mesh.

On this occasion however, as the structure was placed onshore without limitations to space, the design team were able to include an additional single file walkway within the structure with handrails on either side.

This prevented any possible contact with the Heatshields, and it was therefore decided that Locker Mini Shields would be attached to both sides plus the roof of the escape route.

The full supply of Heatshields was designed, fabricated and supplied ready for installation within a dedicated window so as to reduce the plant downtime to a minimum.

About the Project


Bul Hanine PS3 Offshore Bridge Link between the platform and accommodation block is protected with Ladder shields on both sides to protect personnel from the effects of radiant heat in emergency evacuation situations. The shields also provide good visibility and ventilation.

The Heatshields had to be shaped around the deluge valve equipment, with an internal Heatshield closing the gap left by the equipment to prevent the ingress of radiant heat.

The purchasing company was Doha Petroleum and the project is part of a 40 billion Qatari riyals ($11 billion) redevelopment of the existing Bul Hanine offshore oil field located about 120 km (75 mi) east of the Qatari coastline by DOHA, Qatar – Qatar Petroleum (QP). The project is one of the largest to be managed and executed by QP, and it is designed to prolong the field’s life and double its current oil production rate.

About the Project


Transocean Galaxy 1 was selected for a drilling campaign on the Elgin field within the North Sea as a direct replacement for the previously operating Rowan Viking Drilling Rig.

Due to the close proximity of the drilling rig to the flare boom of the Elgin platform there was a requirement to fully enclose the drilling derrick of the rig, which consisted of placing Heatshields on all four sides, as well as covering the crown block roof.

Design and fitting of the support structures, along with the installation of the Heatshields was completed in association with MSD Design Ltd.

Deliverables

In excess of 1750m² Locker ‘Extra Span’ and ‘Double Skin Ladder’ Heatshields were attached to pre-fabricated support structures, which were then lifted into place and clamped to the Derrick structure.

About the Project


Stones floating production, storage and offloading (FPSO) is an ultra deep-water oil and gas development in the Gulf of Mexico. It hosts the deepest production facility in the world, in some 2,900 metres (9,500 feet) of water.

As part of the Stones development, Locker Heatshielding provided both Ladder and Extra Span shields which protect the turret area from the effects of the radiant heat produced during flaring operations. The project continued our team’s excellent long-term working relationship with Single Buoy Moorings.

The Stones development is located in the Gulf of Mexico’s lower tertiary geologic trend, a new frontier in deep water where Shell achieved first commercial production with Perdido. Phase one of the project includes eight subsea production wells tied back to the FPSO. Multiphase seafloor pumping is planned to pump oil and gas from the seabed to the vessel, increasing recoverable volumes and production rates.

About the Project


The ULA oil field in the southern Norwegian section of the North Sea is located in about 70 metres of water.

The field consists of three conventional steel facilities.

The BP ULA platform underwent a major mid-life expansion project and as part of this the complete flare tower and platform was replaced.

The Flare Platform and upper section of the flare tower was manufactured in Incoloy 800HT which broke new ground for Locker Heatshielding in the supply of replacement flare deck panels.
