Welding Certification and ProceduresCERTIFICATION
When a steel and or aluminum fabrication shop decides to become CWB certified to CSA
W47.1/W47.2 Division 2, a welding engineer is retained as required by the standards. Skarborn
Engineering Ltd performs this role by first reviewing the specific requirements with the client
(processes and equipment used, type of manufacturing, etc) and then preparing documentation
which includes welding procedure specifications, welding procedure data sheets, and guidelines for
welder testing. Once a client has become certified, regular shop audits are performed to ensure
conformance to the welding standards. In addition, Skarborn Engineering Ltd can provide welding
consulting at the bidding stage, guidance and recommendations for ongoing welded fabrication, and
troubleshooting.
The products and components fabricated by these clients under CWB certification have included
structural steel for buildings, jet bridges for airports, rocket launchers for NASA, precipitators and
other pollution control components for the power generation sector, topsides for the White Rose
offshore oil extraction platform, accommodations module for the Hebron offshore oil extraction
platform, aluminum gangways and sign structures, and aluminum boats. Our company provides a
unique level of experience in this field with over 45 years of combined welding engineering between
the two principals.
PROCEDURES
Project specific welding procedures have been prepared for a large number of clients fabricating
varied structures and components. Short descriptions of a select few are provided below. These have
been in conformance with various standards/codes.
Hebron gravity base structure living quarters, clients North Eastern Constructors Ltd and Metal
World Inc, to CSA W47.2 and ISO standards. The multistory structure is constructed in Bull Arm and
Argentia, Newfoundland, with the top stories fabricated from aluminum
Long Harbour Electrical Modules, client Cianbro Corporation, to CSA W47.1. Comprised twenty-two
very large carbon steel structures with shop fabricated components that were field assembled for
barging to Newfoundland.
White Rose FPSO Topsides, client Irving Shipbuilding Inc, to CSA W47.1 and contract specifications.
Impact and hardness testing were required in procedure testing of joints with European grades of
HSS carbon steel.
LNG Terminal Saint John, client Sunny Corner Enterprises Inc and Bourque Industrial Ltd, to CSA
W47.1. HSS truss connections with European grade steel and impact and hardness testing were
required.
Coleson Cove Generating Station, client Babcock & Wilcox Canada, to ASME Section IX. Procedures
for welding duplex stainless steel and nickel alloys with GTAW, pulsed GMAW and FCAW required
corrosion testing, ferrite testing and Charpy impact tests.
Tensioner Cassette for offshore oil and gas industry, client Maritime Hydraulic Fabrication Division,
to AWS D1.1 and purchaser specifications. Very thick carbon steel plate and HSS fabrication included
requirements for hardness testing and impact testing at -10° C.
Welding procedures for DND mobile crane designed by Aquila Farco and fabricated by Halifax
Shipyards
Industrial Metal StructuresALUMINUM ARCH SUPPORTS
For wastewater treatment facilities, client Geomembrane Technologies Inc
Aluminum and stainless steel arch or truss support systems have
been designed for approximately 40 geomembrane cover
installations across the United States, Canada, and Australia. Spans
have ranged from 3.6 m (12 ft) to 12 m (40 ft), and supports have
conformed to the Aluminum Specification, CAN/CSA S157, or the
Australian Aluminum Structures Standard, depending on
jurisdiction. Installations have included aluminum walkways and
railings in some cases. A full-scale test of one arch was completed
with the client to verify the failure mode and capacity of shallow arches.
ALUMINUM AND STEEL OVERHEAD SIGN SUPPORTS
For highway signs, clients include New Brunswick Department of Transportation & Infrastructure
(NBDTI), Transportation & Infrastructure Renewal Nova Scotia, L & A Metalworks
Numerous site specific designs as well as a new standard design for NBDTI have been completed inconformance with the Canadian Highway Bridge Design Code. Cantilever, overhead bridge, and singlepost roadside sign supports have been designed, and existing structures assessed where sign areawas increased.
CARBON STEEL AND STAINLESS STEEL TANKS, HOPPERS,
CARBON STEEL AND STAINLESS STEEL TANKS, HOPPERS,& SILOS
Clients include Bourque Industrial Ltd, Noranda Brunswick Mine, McSheffery Industries Ltd, Sunny
Corner Enterprises Ltd, L & A Metalworks Ltd., Warren Environment
Numerous tanks have been designed to API 650 or to the National Building Code where applicable.
Because of Skarborn Engineering Ltd’s expertise in welding consulting, welding access and distortion
considerations are included in the details for all structures
Other examples of designs for industrial structures include an inverted conical storage structure for
gypsum at the Coleson Cove Generating Station, rectangular bin with supporting structural frame for
REPAP Groundwood Mill, and gantry crane for handling spent fuel cannisters at Pt Lepreau
Generating Station. Structural analysis and design programs and classical analysis techniques are
used for the design of structures
Warren Environment has designed many tall steel stacks for the oil and gas industry, and Skarborn
Engineering has performed design reviews of these for a number of Canadian locations
Marine FacilitiesCRUISE SHIP TERMINAL
For Saint John Port Authority through Dillon Consulting
Mooring facilities to accommodate the largest cruise ships in the world at three different berths.
Analysis and design of mooring dolphins to resist forces from currents and wind taking into account
mooring line configuration and properties. Inspection of existing mooring dolphins. Stability analysis
of existing concrete cribs. Foam filled fender design for corner impact forces.
FERRY TERMINALS
For Marine Atlantic
Numerous assessment and improvement projects were undertaken for the Newfoundland and Fundy
services, where the latter was operated by Marine Atlantic. Transfer bridges were inspected, analysed
and rated for Port aux Basques, Argentia, North Sydney, Saint John, Digby, Yarmouth and Bar Harbor.
In some cases remedial designs were prepared for damaged components due to corrosion or
accidental ship impact, or those that required change to accommodate different ramp configurations.
The pile supported dock at Argentia had experienced substantial
deterioration due to microbiologically induced corrosion (MIC).
Analysis indicated that affected piles did not have to be replaced if
the deck live load was reduced. Design of corrosion protection
system to stop MIC was prepared by a subcontractor.
Design of replacement steel sheet pile current and wave protection wall in Saint John due to
corrosion and fatigue damage.
Design of fender system replacements in Argentia and Bar Harbor, including assessment of berthing
forces.
BULK HANDLING AND CARGO TERMINALS
Clients include W. H. Crandall for Public Works Canada, Rothesay Paper, and Little Narrows Gypsum
Co.
Examples of marine facilities are:
Inspection and improvements to existing facilities and design of new facilities for Chatham, NB
and a wharf extension in Newcastle, NB.
Barge berth inspection, remedial design and construction supervision.
Assessment and design of improvements for timber wharf supporting ship loader.
In addition, both Stig Skarborn and Susan Guravich have marine structure experience with companies
other than with Skarborn Engineering Ltd. Examples are the design of Point Tupper, NS, oil terminal
berth #2, shipping terminal in Spragge, ON, field surveys for fishing harbour in Yemen, design of oil
tanker and bulk handling terminal in Nanticoke, ON, and construction surveying for Saint John and
Bayside, NB, terminals.
Training and Workshops
Skarborn Engineering Ltd has prepared a number of presentations
on topics related to welding, and these have been given to a wide
audience including welders, welding supervisors, engineers,
technicians, detailers and managers. Companies participating in
these sessions have included metal fabricating firms and detailing
companies. Presentations have also been given to the New
Brunswick Department of Transportation & Infrastructure and
Nova Scotia Power Inc. Formats have included PowerPoint, text
review of standards/codes, and on-site training on the shop floor.
The following courses are available on request:
