ABS AIP for Deep-sea Mining Riser and Lift System
;s deep-sea mining system design, which was the first since ABS published the Guide for Subsea Mining, detailing class requirements for the design, construction, operation, and survey of mobile offshore mining units in 2020. This latest AIP also refers to the ABS Guide for Building and Classing Subsea Riser Systems.“Deep-sea mineral extraction requires us to push the technological frontiers, going further and deeper and developing new capabilities. ABS is supporting the industry every step of the way. This technology is increasingly key to securing the minerals utilized in electric vehicle batteries
Safety Boost: 4Subsea to Monitor Var Energi's Drilling Ops at Balder
to measure movement and strain on the wellhead. "It applies advanced algorithms and machine learning combined with the deep domain expertise to monitor fatigue damage accumulation, well support, and structural integrity," 4Subsea said.The service creates a digital twin of the well and riser systems combined with boundary conditions and updated with sensor data. Sensor data is then collected using remotely operated underwater vehicles and uploaded to 4Subsea's digital service 4insight, which performs advanced analysis on the data. "The results are presented as easy-to-interpret
Bosch Rexroth Launches Subsea Clamping Cylinder for BSC
. This prevents material fatigue and premature wear with a predefined clamping force. The integrated clamping unit allows straightforward, reliable actuation during commissioning and removal – even after long periods of use, the company said."Bend Stiffener Connectors (BSCs) protect riser systems against premature material fatigue coming from movements such as those caused by waves. This helps protect valuable investments and increase the availability and productivity of the offshore equipment. In a fully automatic BSC, a number of Rexroth clamping cylinders are used as a system,"

Reviewing Sapinhoá-Lula NE BSR System
reservoirs, the difficulty of reliably and safely bringing the oil and gas to production FPSOs have been compounded by the extreme water depths involved.In 2011 Subsea 7 was awarded a milestone subsea umbilical, riser and flowline (SURF) contract by national operator Petrobras for four decoupled riser systems to be installed in the Sapinhoá-Lula NE fields located in the Santos Basin, in the largest engineering, procurement, installation and commissioning (EPIC) SURF contract awarded to date in Brazil. The pioneering technology for connecting a large number of wells to a single FPSO was
Subsea 7 Bags Offshore Norway Deal
the Gjøa field, in a water depth of approximately 360m. The Nova field development is a subsea tie-back to the existing Gjøa semi-submersible production facility. The contract award comprises the Engineering Procurement Construction Installation (EPCI) delivery of the pipeline and riser systems, and the transport and installation of subsea production systems and umbilical system. Fabrication of the pipeline will take place at Subsea 7’s spoolbase at Vigra, Norway. Project Management and engineering will commence immediately at Subsea 7’s offices in Stavanger, Norway
Aquaterra Names Hawkes Financial Director
Energy, said, “Nick’s appointment marks an important development as the company shapes itself for future growth. His experience will bring important skills to our top management team.” Aquaterra, which has operations in Aberdeen, Norwich and Cairo, provides riser analysis, riser systems, offshore structures, repeatable products and it’s integrated WellStart specialism to the global oil and gas industry. The company recently designed, fabricated and installed a new Sea Swift platform for PICO Petroleum Integrated Services, the lead contractor for the Amal field in the Gulf
Revolutionizing Deepwater Drilling Riser Buoyancy
DRBM equipment, reducing the necessity for auxiliary suppression equipment and alleviating complicated and time intensive riser running and retrieval procedures. Inverted helical straking of drilling riser buoyancy modules allows for in-line drag reduction and VIV suppression of drilling riser systems through the use of a tri-helical groove design molded into the outer profile of the buoyancy modules. The origins of the design stem from external helical strake designs, which have been used in the offshore industry since the late 1970s to suppress VIV of slender structures. However, the inverted
ABS Issues RP for Hybrid Riser Systems
ABS has published the ABS Guidance Notes on Subsea Hybrid Riser Systems, the first set of recommended practices for hybrid riser systems in the offshore industry. “The introduction of new approaches like those being considered for hybrid risers has the potential to positively impact safety,” explained ABS Chairman, President and CEO Christopher J. Wiernicki. “At ABS, we understand how important it is to keep pace with industry advances in order to develop leading guidance that is in step with the introduction of new components and evolving technology.” Developed
