ACE Winches, a deck machinery specialist, has secured a spooling contract with Oceaneering for Shell’s Prelude Floating Liquefied Natural Gas (FLNG) project.
The contract will be the first time ACE Winches’ 500-tonne reel drive system is used. The tool is an upgrade of its existing 400-tonne system that has been engineered and manufactured at ACE Winches facilities in Aberdeenshire. The product range has been developed for high tension spooling and the deployment and recovery of subsea products such as umbilicals, risers and flow lines, flexible pipelines, power cables, telecommunication cables, tubing, wire ropes and mooring lines. It can accommodate a gross weight of 500-tonne.
“As our clients projects continue to venture to even greater depths, we understand the need for this equipment to operate in harsh conditions and as a result, have developed it to ensure we are accommodating the ever growing needs of the oil and gas industry,” said Alfie Cheyne, CEO, ACE Winches.
The scope of work will see ACE Winches spool 4400m of umbilical, with a diameter of 229mm on to a 12.2m reel. The weight of the umbilical is the heaviest Oceaneering has ever spooled with a total weight of 426-tonne.
ACE Winches modified its existing 400-tonne reel drive system to meet the client’s specific requirements with an added base frame and packers to allow the 12.2m reel to be spooled on the quayside.
“ACE Winches has invested heavily in the design and manufacture of reel drive systems and we are excited to be expanding our capabilities to allow for 14m maximum flange diameter and a 500-tonne load,” said Chris Waller, engineering manager, ACE Winches.
The company also supplied a total of 10 qualified commissioning engineers and technicians to assemble the ACE 500-tonne reel drive system quayside, before operations started, with a further six operating technicians providing a 24-hour service to complete the first phase of spooling.
The patent pending 500-tonne system consists of two towers that disassemble into eight modules for easy transportation. The towers use a slave and master configuration, with two gear boxes in each drive hub.
