Webtool Cutter Used in Downhole Decommissioning Tool
;), whilst still being capable of cutting a steel wire and two hydraulic lines in a single operation. Incorporating a double acting cylinder, the 172mm (6.75”) high cutter weighs less than 6.5kg, making it the smallest subsea cutting tool ever produced by Allspeeds.“The Webtool was an excellent solution for us, making that part of the operation both simple and reliable. It was great to work with Allspeeds on this project and their equipment helped make it a success for the maiden campaign in 2022,” said Richard Henderson, Engineering Director, James Fisher Decommissioning
Case Study: Floating top marks for piles in flooding rivers
submerged obstacles. Top marks and lights will probably be damaged and, following the floods, beaconing must be inspected and repaired to restore full navigability of the channel, which implies cost and delay in the river operational navigation.The use of buoys vs. floating top marksBuoys are an excellent solution for river channels with a constant flow as their mooring can be designed with a long scope and their movement perpendicular to the axis of the channel will be minimal. In the Douro river Balizamar buoys work perfectly with 3 knots of current. However, when flow is not constant having buoys
