THE CUTTING EDGE Te rental side of the sector remains extremely busy. In just one example of news in this field, Subsea Technology & Rentals (STR), a leading provider of specialist survey and inspection rental equipment, products, and data-enabling services to the offshore energy market, has strengthened its rental fleet with the addition of two high- performance Webtool cutters, the HCV275 and RCV160. Tese cutters, designed to suit specific customer requirements, can be deployed at subsea level, either mounted, operated by an ROV, or onboard a vessel for either planned production cutting of offshore wind power cable or as an emergency cutter. As reducing vessel hours is of paramount
importance to installation companies, deploying subsea cable for offshore wind projects needs to be as efficient as possible. Te HCV275 and RCV160 feature integrated interlocks to ensure that no cut can be activated until the anvil is fully deployed. Te interlock takes away the possibility of human error and makes it ideal for deployment subsea, where visibility is poor. Tis innovation was introduced
following discussions with a number of customers who had either damaged or had come close to damaging their cutting tool by commencing the cut operation prior to the anvil being fully engaged. Unlike other cutting methods, where
there is a risk of the item flexing during cutting and either trapping or snapping the blade, closing the guillotine’s anvil locks the cable in position to ensure the cut is completed successfully, typically within a couple of minutes. Technical director of Allspeeds, Rory
McGarry, comments: “We are constantly looking at ways to innovate and improve the design and functionality of our cutting tools to aid the customer with their operations through improvements with safety and ease of use.”

BETTER CONNECTED Te subsea cable supplier and servicer, JDR, owned by the TFKable Group, has been awarded a contract by Petrogas E&P Netherlands to supply two umbilicals for the A15 and B10 offshore conventional gas fields in the Netherlands. Te fields are located in quads A & B, in a shallow water depth of 115 ft and are expected to recover 17.25 Mmboe, comprised of 103.5 bcf of natural gas reserves. As Europe strives to meet high gas demand, the production from this project will support in meeting supply targets. JDR will engineer, design and manufacture two subsea umbilicals, that range from 10-13km in length, to provide vital power to two new platforms located at the A/B shallow gas field. Te umbilicals incorporate hydraulic hoses, chemical injection hoses, electrical cables and fibre optic cables that enable communication between the platform facilities. JDR will also deliver topside umbilical termination unit pull-in heads, hang-off bodies and umbilical termination assemblies for the project. Rory Graham at JDR says: “We’re delighted to be selected by Petrogas for this critical project at a time when energy security couldn’t be more important in Europe. Te demand for natural gas is high and we’re here to support our customers in ensuring production is maintained while oil and gas remains a vital part of the energy mix, and as the industry journeys through the energy transition. We’ll manufacture all the cables at our facilities here in the UK and our technical team of experts will be fundamental in ensuring we meet the swift turnaround time.”
LOTOS NOTES Lotos Petrobaltic, part of multi- energy concern Orlen, has ordered Saab’s Seaeye Leopard work class robotic vehicle to service underwater infrastructure within Poland’s B3 and B8 oil fields in the Baltic Sea.
the market, Lotos Petrobaltic chose the Seaeye Leopard for its versatility and ability to accommodate far more equipment options for a wider range of tasks. Current tasks include the comprehensive inspection of underwater structures, construction cleaning, cutting, dredging for inspection, basic support for head installations and support for diving teams. Te Leopard’s adaptability is particularly
important for Lotos Petrobaltic. Te vehicle’s design means it can be expanded and configured in the future to perform comprehensive measurements and underwater works and inspections for a wide range of customers. It will be equipped with a survey package to include multi-beam sonar, lidar and pipetracker. Teir current Leopard configuration includes a Sonardyne DVL/INS survey system, Sprint-Nav INS, Digital Edge recording and event system, five cameras including Kongsberg HD system, also a One Laser for video and measurement, Tritech Super Seaking sonar, a seven-function manipulator, Schilling Orion gripper, electric torque tool, rotary disc cutter, WeSubsea dredge system, FlexiClean cleaning tool, water jet system and caviblaster, Cygus ultrasonic thickness gauge, multiplex survey pod and tooling sled. Te Leopard package also includes a tophat tether management system (TMS), an ‘A’ Frame launch and recovery system (LARS) and a custom control cabin. At the same time, Lotos Petrobaltic is
preparing its supply vessel, Bazalt II, as a dedicated operational platform for the Leopard, including adapting it to receive the LARS system and the custom configured control cabin, along with additional peripheral systems.
