Abstract An alternative methodology using new preventative technology to manage cybersecurity exposure on deepwater drilling rig assets is presented. For the past two years Shell's Deepwater Wells business has been evaluating typical cyber defence approaches and undertaken cybersecurity risk assessments and penetration tests. These activities have demonstrated the challenges attaining cybersecure drilling rig environments. Whilst cyberattacks increase in frequency, adaptability, and become cheaper to launch, regulatory and liability insurance requirements are also evolving. To achieve the goal of cyber-resilience, a major Operator has collaborated with a cybersecurity firm to trial technology for rapidly and reliably protecting deepwater rigs. The paper presents aspects of the numerous challenges faced and offers a different approach using new technology applied to both supplement and accelerate the attainment of a cyber-resilient environment onboard deepwater drilling rigs. It shares the deep dive lessons learnt leading to a more comprehensive understanding of how to protect drilling rigs and their safety critical control systems. Aside from addressing technical attributes using risk vs. maturity based methods, the approach also caters to business demands of short term rig contracts, managing multi-vendor legacy systems and satisfying increasing digitalisation/remote access needs with associated reductions in overall cybersecurity CAPEX spend.

Sediment Deformation

Abstract Drilling to the bedrock of ice sheets and glaciers offers unique opportunities for examining the processes occurring in the bed. Basal and subglacial materials contain important paleoclimatic and paleoenvironmental records and provide a unique habitat for life; they offer significant information regarding the sediment deformation beneath glaciers and its effects on the subglacial hydraulic system and geology. The newly developed and tested Antarctic subglacial drilling rig (ASDR) is designed to recover ice and bedrock core samples from depths of up to 1400 m. All of the drilling equipment is installed inside a movable, sledge-mounted, temperature-controlled and wind-protected drilling shelter and workshop. To facilitate helicopter unloading of the research vessel, the shelter and workshop can be disassembled, with individual parts weighing <2–3 tons. The entire ASDR system weighs ~55 tons, including transport packaging. The ASDR is designed to be transported to the chosen site via snow vehicles and would be ready for drilling operations within 2–3 d after arrival. The ASDR was tested during the 2018–2019 summer season near Zhongshan Station, East Antarctica. At the test site, 2-week drilling operations resulted in a borehole that reached bedrock at a depth of 198 m.

Service Activity

The idea is to replace drilling rig, which is utilized for work over/well services activities, with working barge. The challenge comes from the operation and structural platform capacity since the majority of PHE WMO wellhead platform has limited capacity issue and braced monopod type. To minimize the risk of drilling equipment placed on the platform, engineering study is proposed to ensure the reliability of the platform. The process and method of operation during well service activity will also be developed. The proposed mitigation includes: Global Structural Check for Platform Integrity, Local Structural Check for Strengthening, Localized load for Additional Equipment, and Weather-Time-Frame Constraint. Using the proposed methods, PHE WMO can ensure the platform integrity and ensure SAFETY during well service activities.

This article summarizes development of the Azurite field as a way of providing context for evolution of the Floating, Drilling, Production, Storage and Offloading (FDPSO) concept. It also reflects on the project’s technical and economic drivers that led the Azurite project team to select the FDPSO concept. The paper also highlights other application for FDPSOs and discusses some of the key variables that determine the suitability of the FDPSO concept for use in field developments. The step change in economics afforded by the incorporation of a drilling rig onboard a conventional FPSO brings new hope to fields of similar geometry and in similar environments that heretofore were considered marginally economic or uneconomic. The FDPSO concept also has application as an early production system, in advance of full-field developments. The concept has tremendous potential as a ‘game changer’ for field developments, whether it is employed to unlock the value of marginal fields in deepwater – even in a low oil price environment – or as an early production system. As the concept employs a drilling rig onboard the vessel, traditional challenges regarding deepwater drilling rig day rates and availability are eliminated.

As one of the core equipment components of oil and gas drilling rig, derrick is also the main heavy-duty component. Working environment of derrick is quite bad, the material for which should have not only high strength, but also good plasticity, toughness and weldability. In this paper, the chemical composition, microstructure, tensile properties, impact properties and hardness of three typical Q690D high strength low alloy steel manufactured from different methods were studied. The application feasibility of Q690 for drilling derrick manufacture was analyzed. The experimental results show that the carbon equivalent, tensile properties and impact absorption energy of Q690D steel with different thickness obtained by TMCP and Q-T process were obviously higher than the requirement of corresponding standard. TMCP Q690D steel had better toughness, lower carbon content and carbon equivalent, and its micro-structure was granular bainite. Carbon content of Q-T Q690D steel plate was relatively higher than that of TMCP Q690D, and the toughness was slightly lower than that of TMCP Q690D. The microstructure Q-T Q690D was tempered sorbite, and there was certain zonal segregation in center part. The thickness of steel plate used in derrick was usually less than 40 mm, whose manufacturing technology of Q690D was mature. There is broad application prospect in the field of drilling equipment. The application of Q690D for drilling equipment not only improve the strength grade of equipment materials, but also help to optimize the design of components and ensure service safety.

As drilling deep, large diameter, high drilling efficiency, adapting to a wide range of rocks, the down-the-hole drill is widely used currently as a large-scale rock drilling equipment. Integrated with the hydraulic rotary cutting pneumatic impacting drill and the down-the-hole hammer, the HZCLQ120 multifunctional hydraulic down-the-hole rock drilling rig was developed. The technical principle, main innovations, technical specification and test results were introduced. The new drilling rig can be widely used in rock blasting of railway, highway, water and electricity, mining, and urban construction.
