In a 20,000 sq. ft. fabrication shop in St. John’s,
Newfoundland, Canada, Orphan Industries Limited’s 50 welders, pipefitters, millwrights, and electricians work 12- hour shifts around the clock, building ROV launch and recovery systems (LARS) and other subsea equipment, primarily for the offshore oil and gas industry. In Orphan
Industries’ test facility outside, the LARS that has just been built is picking up a 40,000-lb. load weight to simu- late an ROV and manipulating it back into position.
Once the tests are complete, this unit will be loaded onto a tractor trailer and shipped to Dynacon Inc. in Bryon,
Texas where the winch will be added and the complete system tested before it is transported to a location offshore
Africa where it was designed to operate. The LARS are deployed on offshore supply vessels and rigs around the world. Dynacon builds its own LARS but contracts
Orphan Industries to handle the overflow. In addition,
Orphan Industries is a major supplier of LARS for
Houston-based Oceaneering International, Inc. which pairs the LARS with its own ROVs. Dynacon and
Oceaneering are major suppliers of LARS for the offshore oil and gas industry.
Orphan Industries’ A-frame LARS are fabricated from low-temperature, high-impact steel. The units range in weight from 42,000 to 58,000 lbs., are nearly 11 ft. wide, 24 ft. deep, and extend to a maximum height of 29 ft. Its lifting capacity is 30,000 lbs. and in the overboard posi- tion it is capable of putting the ROV into the water 13 ft. from the edge of the vessel. The company’s test facility incorporates a concrete pad that weighs 260,000 lbs. which enables them to do static A-frame load tests up to 56,000 kg.
In addition to LARS, Orphan Industries also builds sub- sea well temporary guide bases (TGBs) and permanent guide bases (PGBs) for Cameron International
Corporation (Houston), spooling for Transocean (Houston) and Atlantic Towing (St. John’s), winches for
Dynacon, and shipping containers for Harvey’s (St.
John’s). Jobs on the fabrication shop floor on this day include: the base and part of the crown of a DT 4400
LARS for Oceaneeering, a gas uplift pipe for the dehydra- tion structure at Hibernia, a flexpipe for a winch platform at Hibernia, drill collars requiring maintenance work for
Schlumberger, and tubular steel, which will be fabricated into a container.
DFB Group, a St. John’s company that manufactures, fabricates, services and repairs offshore, marine and indus- trial equipment, established Orphan Industries, a wholly owned subsidiary, in 2005 to manufacture LARS. “We’re not steel-bashing machinists,” explains DFB Group’s
Chief Engineer Torfi Thorarinson. “What we build has gears, belts and hydraulics, as opposed to just welding steel together.” He recalls that Orphan Industries com- peted with 25 bidders worldwide for the first contract to build five DT4400 LARS for Oceaneering. Orphan
Industries and one other bidder in Singapore were award- ed contracts to build three, with the promise of another two if they maintained the schedule and quality. “We won the contest, got the next order for 10, and have continued to build for them ever since,” Thorarinson said. To date, the company has built 57 LARS which are being used by all of the major oil companies on offshore supply boats and rigs in various locations around the world including
Newfoundland and Labrador, Singapore, Norway, and
Africa. The number of LARS shipped has increased sharply from 10 in the first three years to 47 in the last three years. Sean Power, DFB Group Vice President
Business Development, attributes much of that growth to
Orphan Industries’ inroads in improving plant efficien- cies. The company initially enjoyed a 20 per cent compet- itive advantage internationally due to a favorable exchange rate between the US dollar and Canadian dollar. When they lost that advantage, they started looking for ways to streamline production. “We hired one of the best lean 20 MTR June 2011
