The Sable Offshore Energy Project (SOEP) through its alliance partner MM
Industra/Brown & Root Joint Venture is requesting expressions of
interest from qualified Nova Scotian and Canadian Companies capable of
supplying load bearing flare radiation shielding for the North Triumph
Platform as
described below. Companies interested in prequalifying to bid on this
package should submit their corporate resumes indicating relevant
experience and expertise with similar products to the following address
prior to the closing date indicated above. SOEP reserves the right to
make the final determination of which firms will qualify to bid on the
Project.
Scope of Work
Introduction
This specific describes the necessary requirements for the Radiation
Shielding which is to be located on top of the Flare Tower Structure.
The Radiation Shielding shall protect the Flare Tower against the
effects of Flare Radiation and provide adequate support as a platform
surface for assembly and maintenance work on the Flare.
Requirements
The Radiation Shielding shall ensure that the surface temperature of the
underlying structural steelwork remains under 100?C during flaring. This
is to ensure that the steelwork is not damaged as a result of exposure
to severe thermal cycling effects.
The panels and fixings shall be designed to withstand the effects of
wind, snow and ice loads in addition to a maximum imposed distributed
load of 5KN/m2.
The Radiation Shielding shall be supplied as individual panels designed
to be installed together on the Flare Tower Supporting Structure.
The panels shall be designed to be installed with sufficient gap to
allow for expansion and shrinkage during thermal cycling and designed to
prevent internal panel stressing or buckling. The top grating shall be
attached to the panel in such a manner as to allow individual expansion
of the sections and avoid buckling or warping.
Access Hatchways & Handrails
Hatchways shall be provided with hinged access doors secured with shoot
bolts on the underside. Handgrips shall be provided to raise the doors
open and hinges shall be welded to bearer bars on the doors and the
shield panels.
The Radiation Shield shall have handrail sockets welded at intervals
around the heat shield periphery and around the access hatchway
(optional).
Fixings
The panels fixing shall be designed to be welded to the structural
steelwork with a flat retaining plate which screws into position. A
tensioning shall be used to ensure that the retaining plate is secure
against the panels. The fixings shall provide for minimum necessary
movement during thermal cycling (to avoid buckling and warping) while at
the same time holding each panel in place to the supporting structure.
Each retaining plate shall have a tab which shall be bent to lock it
against the panel to prevent the retaining plate working free. The
tensioning tool shall have a notch design in the handle to bend the tab
into position. Anti shuffle plates shall be located on the outer panels
to prevent sliding out of the panels under windload or thermal
ratcheting.
Materials of Construction
The Radiation Shielding shall be preferably manufactured in the
following materials, which have been proven over many years exposure to
live flaring conditions on offshore platforms.
Loading Supporting Grating
Incoloy 800 (HT)
Panel Side Members
Incoloy 800 (HT)
Reflective Foils
Inconel 625
Expanded Metals (cold underside of panel) Stainless Steel 316
Fixings
Incoloy 800 (HT)
Material certificates shall be provided for the various materials used
and traceability to EN10204 3.1B shall be provided where practical.
Testing and Experience
The Radiation System shall have undergone suitable heat tests to confirm
its performance in operation. In addition, the Radiation Shield shall be
a proven design; i.e. it shall have a history of successful operation in
an offshore environment under similar conditions.
