1.0 INTRODUCTION This document provides information about the engineering and design of ProTek™ Fire and Blast Protection systems and their track record of projects. The report describes how SCS meets the project requirements with the ProTek™ Fire and Blast Wall panels.

• Connection Details for the panels to the steel structure

• Relevant Projects including accommodation blocks as references

2.0 CONNECTION DETAILS

The ProTek™ fire and blast wall panels are designed to be bolted to secondary steel structure to form a sealed fire / blast wall that resists fire and blast loading and is gas and water tight. There are many bolted arrangements for the ProTek™ panel and typical examples are given in the drawings and photographs attached in Appendix A. The design details rely upon a bolted connection because the ProTek™ is manufactured from high strength composite materials that cannot be welded. It is therefore common for steel supports to be welded in place for fixing the panels, which are bolted to the steel supports to transfer the blast loads to the main platform structure. The ProTek™ panels are designed to deflect elastically under the blast load so that they are not deformed and are able to resist a hydrocarbon jet or pool fire if it occurs after the blast. The blast load is absorbed by the panels and transferred to the bolted ends where the panel fixings resist the bending and shear loading and transfer the load into the main platform structure. The fixings are also designed to restrain the panels immediately after the blast overpressure. Following the explosion the resultant air movement generates a smaller negative suction load that pulls the panels away from the wall putting the bolts into tension. The connection details are calculated for every application and form part of any engineering or certification report that is produced for a ProTek™ fire and blast wall. Fixings are either galvanised high strength steel or 316 stainless steel.

3.0 RELEVANT PROJECTS

SCS has provided ProTek™ fire and blast walls and other protection systems for a number of demanding offshore oil and gas projects, which are summarised along with their performance requirements in Appendix B. Details of some of these projects are described below:

3.1 Ekofisk Tank (2/4-T) Control Centre

This project was part of a platform refurbishment by Phillips Petroleum and was designed to improve the fire resistance of the control centre by attaching thin and lightweight fire and blast resistant panels to the existing support structure. Photographs are attached in Appendix C that show the existing control centre both before and after the ProTek™ “Thin Wall H60” fire and blast wall panels were installed. In this case the fixing methods were based upon the use of “Hilti” fixings that were attached to the main steel supports. Panels were made to span 3.5m between vertical supports and were built up over the entire 1,000 m² surface of the control centre. The project requirements also included an installed system that did not reduce the positive pressure integrity of the control centre. In addition there were a number of environmental performance requirements for wind, rain, snow and ice loadings. The project performance requirements are 0.1 barg overpressure blast loading and H60 fire performance. A DNV Type Approval certificate was awarded for this “Thin Wall H60” product.

3.2 Tartan Alpha Intermodule Fire and Blast Wall

This project was part of a platform upgrade to divide an existing module and to separate the divided module with a lightweight fire and blast wall. Photographs are attached in Appendix D to show the installed ProTek™ fire and blast wall. This was provided as a gas tight barrier to resist the effects of an explosion load of 1 barg followed by fire loading for 1 hour jet fire (J60) and 2 hour hydrocarbon pool fire (H120). The connection method is a bolted arrangement to steel plates that are welded to the main tubular structure similar to that shown in the drawing in Appendix A.

3.3 Ekofisk B11 Stairtower Cladding

This project was part of a platform upgrade to protect a new stairtower that was constructed to provide safe egress from a hazardous area of the platform. Photographs are attached in Appendix E to show the panels attached to the stairtower structure. The ProTek™ panels were provided as a gas tight barrier to resist the effects of an explosion load of 0.2 barg followed by fire loading for 1 hour (A60).

3.4 Tartan Alpha Temporary Safe Refuge Cladding

This project was part of a platform upgrade to improve the fire protection of a Temporary Safe Refuge on the Tartan Alpha platform. SCS were requested to design an A60 fire barrier to be entirely sealed to prevent water ingress and maintain a positive pressure within the refuge itself. Drawings of the proposed ProTek™ solution are included in Appendix F.

3.5 Eldfisk 2/7-FTP Fire and Blast Wall

This project was part of a platform upgrade to install a new barrier to an existing platform offering protection against an explosion load of 0.3 barg followed by hydrocarbon fire loading for 2 hour to H0 standard. A document showing a drawing of the fire and blast wall along with details of doorways, pipe and cable penetrations is given in Appendix G.

3.6 Britannia Lifeboat Fire Protection

This project was part of a platform upgrade to install new accommodation on the Britannia platform, which required an additional lifeboat to meet the regulations for the additional personnel on board. SCS provided a ProTek™ Fire and Blast protection cladding system to prevent damage to the underside of the new lifeboat from the effects of a pool fire in the sea. The protection requirements are H0 for 1 hour’s hydrocarbon fire at 200kW/m² heat flux and resist explosion loads of 0.1 barg Photographs are included in Appendix H.

3.7 Beryl Alpha Acoustic and Fire Protection Modules

In response to a growing problem of equipment generating high noise levels placing restrictions on the amount of time that can be spent in an affected area on the Beryl Alpha platform SCS developed a concept of cladding and enclosures to restrict the noise levels and deliver fire protection. The ProTek™ protection system is designed to restrict the noise levels, which has been demonstrated by testing to offer up to 38dB reduction. It also offers fire protection to A60 standard and has to maintain a positive pressure within modules housing the equipment. This is achieved by a series of sealed modules built using ProTek™ panels around gas turbines and other noise generating equipment. This also includes moulded protection systems fitted around piping and ducting to prevent noise being emitted elsewhere around the platform. Design drawings showing the arrangements are given in Appendix I along with a data sheet outlining the noise reduction characteristics to the Norwegian NORSOK standard R-004 for piping and related systems.

3.8 Offshore Substation Transformer Fire Protection Modules

The development of offshore wind farms has led to a requirement to site high voltage transformer platforms offshore in order to distribute the electricity generated back to shore. SCS have led the development of modules that are designed to offer fire and blast protection in the event of a transformer explosion or fire to protect personnel and other transformers on the platform. This modular system is designed to be weather tight in order to protect the equipment from the offshore environment. It will also allow a controlled atmosphere to be generated around the equipment with an expectation that the module will maintain a positive pressure. This is achieved with proprietary sealing details between panel joints and around any penetrations, doorways etc. A data sheet explaining the protection system concept is attached in Appendix J.

3.9 MOPUstor Yme Fire & Blast Wall Penetration Panels This project is part of the Yme redevelopment and required protection panels to be supplied to fit around penetrating pipework and structural beams. The double-sided protection panels are designed to meet an explosion load of 0.7 barg, 15 minutes hydrocarbon jet fire with an H60 requirement on one face and H0 on the opposite face. Photographs showing typical pipe and cable penetrations are given in Appendix K.

4.0 SUMMARY

ProTek™ Fire and Blast Walls This document has been prepared to provide some further details about ProTek™ Fire and Blast Walls and the general interface and installation details. Attached below is a GA drawing ref. PH/406-A-01670 Revision E04 showing a typical fire and blast wall installed on the Conoco Phillips 2/7 FTP platform. Attached on pages behind the GA drawing are photographs of some of the details on the Fire and Blast Wall. Comments are included on the GA drawing to refer the reader to specific photographs. In principle the fire and blast wall is comprised of a set of nominally 100mm thick composite panels that are bolted to a secondary steel structure that is attached to the main platform steelwork by bolting or welding. The ProTek™ panels are manufactured from lightweight structural composite that incorporates the thermal performance and jet fire resistance within one moulded structure. This obviates the need for separate insulation and liners and means that the panels can be installed in one operation by bolting to the support steelwork. The details shown on the drawing include doors, edge details, bolting arrangements, cable and pipe penetrations. The basic principle is to engineer the panels by survey of the existing blast wall area to fit around the pipes and cable penetrations and to incorporate the door opening. The panels are manufactured with openings to fit around these existing features. This allows panels to be installed rapidly. Cable Penetrations The panels are designed to incorporate standard proprietary Marine Cable Transits (MCT’s) such as those supplied by MCT Brattberg, Lycab or Hawke. The MCT’s are bolted onto the panels such that the penetration blocks can be fitted around the cables during the final stage of the installation. Pipe Penetrations A similar approach is taken with pipe penetrations where openings are moulded into the panels to accommodate the pipes. The photographs of the fire and blast wall show a detail where the panel is moulded to fit closely to the pipes with a small installation clearance that seals up in the event of fire. However larger openings can be incorporated for pipes that have movement due to thermal expansion or vibration. In this case a larger opening is moulded and is closed up with a standard fire and blast resistant pipe penetration seal such as those supplied by Bestobell. Doorways The doorways incorporate standard fire and blast rated door systems supplied by others and the panel openings are engineered to incorporate the door frames and steelwork to support the fire and blast doors.

TECHNICAL INTEGRITY, ZERO MAINTENANCE, LOW LIFE COST

The advent of large scale offshore wind farms

is calling on more sophisticated technology for

transmission and distribution into the onshore grid.

Many of these systems utilise high voltage DC

transmission (HVDC), that ultimately will form part

of the international Supergrid.

The announcement of the UK Round 3, facilitating

25GW of new offshore wind by 2020, will advance

a new era of offshore substation technology, and

simultaneously a growing need to keep that energy

transmission safe and secure.

Protek™ lightweight composite enclosures for

transformers and other critical equipment provide

an economic solution for fi re and blast protection.

The SCS design team understands the hazardous

environment offshore and has learned to design

for this harsh environment - inclement weather

- wide temperature range - relentless salt spray

and corrosion risk throughout the platform’s life

- typically 30 years. In addition pollution prevention

is high on the list of risk mitigation.

Solent Composite Systems

The size and complexity of offshore substations demands that the investment is safeguarded and the personnel who maintain them can work safely in a low risk environment. Composite enclosures for transformers and other critical equipment as well as walk-ways and escape-ways provide an economic solution requiring no inspection or routine maintenance and therefore low life cycle cost. Each area is carefully assessed for fi re and explosion risk and protection structures are designed accordingly.

The lightweight ProTek™ composite multi-layer structure is virtually inert, thus providing exceptional corrosion and weather resistance over a 30 year life cycle - signifi cantly higher than spray-up and steel systems - and can be easily assembled onshore or offshore . ProTek™ composite panels are mounted on a corrosion resistant steel frame to resist severe blast up to 1.5 barg and environmental wind and snow loads, thus providing an extremely rigid but lightweight structure. Blast relief vents may be included within the design to prevent overpressure build up whilst allowing quick and easy on-site installation.

Capital investment and operating costs have to be carefully managed whilst operational security, reliability and safety have to be maximised. Here SCS experience plays a key role with hundreds of ProTek™ installations already installed offshore in the North Sea.
