Operators with subsea developments on the Norwegian Continental Shelf have the last 20 years aimed for better efficiency and reduce equipment and personnel needed on the rigs in relations with subsea completions. Drivers have been reducing HSE risk, reduce need for modifications on the rigs to accommodate for subsea related equipment such as reels and workover control systems, and reduce cost, rig time and emissions. Many measures have been implemented such as removing need for landing string and wireline operations with deep-set pump-open or disappearing barrier plugs, installing Intervention and Workover Control system (IWOCS) to operate all systems suppliers’ tools from same unit, use of ROV Workover Control System (RWOCS) subsea HPUs to control the Xmas Tree (XT) to remove the tree running tool (TRT) umbilical, developing a hydraulic-electric remote operated control system communicating on wired drill pipe to the tubing hanger running tool (THRT) to remove the need for THRT umbilical and IWOCS, to mention some. This paper describes one of the last inventions; a mechanical tool for installation of tubing hangers (TH) that also removes the need for remote communication and hence dramatically reduces complexity and potential for faults. The mechanical tubing hanger running tool is called THRUT and has been developed by CCB Subsea in cooperation with Equinor. First umbilical-less subsea completion ever run with a THRUT was successfully conducted on the Equinor's Heidrun field on well E-2 from the Transocean Encourage drilling rig in March 2022. Following the first well, the THRUT has been run on 8 more wells for Equinor and 3 wells for Norske Shell. The tool concept is accommodated to interface to any kind of subsea horizontal XT (HXT) systems delivered by either Aker Solutions, TechnipFMC, OneSubsea, BakerHughes, or other system suppliers. And also, the tool is operated offshore by the subsea system supplier in charge of the subsea completion, no extra personnel from CCB Subsea is required offshore. Result is an efficient and robust tool with profile of low risk, low cost and less personnel needed. The paper describes the philosophy and requirements for the system design, the device functioning, and method for mechanical umbilical-less installation of TH in subsea HXTs, and also summarizes the most important results and operational experiences with regards to the advantages related to HSE, time, cost, personnel need, logistics and rig interface.

Goal Zero underpins Shell's strategic ambitions and Life-Saving Rules are a proven enabler in achieving Goal Zero. Shell has embraced the opportunity of transitioning from twelve Shell Life-Saving Rules to nine industry Life-Saving Rules (IOGP) in pursuit of eliminating Serious Injuries, Illness and Fatalities (SIFs). This is not just a simple switch from one set of Rules to another. It is part of a multi-year journey to strengthen the mindset and behaviours of ‘Who we are’ in Shell and deepen our commitment to Human Performance. This paper explains the context of the Life-Saving Rules, why Shell decided to transition, an overview of how we managed this large-scale change, and the impact so far and remaining dilemmas in the journey. Since Shell introduced 12 Life Saving Rules in 2009, the Rules have helped to save many lives and prevent life altering events. Shell decided to transition to industry nine Life-Saving Rules across whole company due mainly to a) inclusion of Line of Fire Rule; b) strong desire to standardise based on the pull from our major suppliers; c) rolling out ‘I-statements’ instead of ‘dos & don'ts’. Preparations for the transition began in early 2020 for a global launch on Safety Day 2021 (an annual dedicated engagement session with all staff and contractors about safety led by leaders across Shell). The "I statement’ language of the new Rules empowers individuals to figure out with their peers how to comply and encourages peer-to-peer intervention to enable compliance throughout the work task. This means the Rules are more than just Rules; they help create the environment in which people feel safe and responsible to speak up triggering conversations about what can make compliance difficult, resolving any dilemmas before work starts. When failures do occur, how leaders respond matters. Leaders must engage to understand how context drove behaviour and encourage people to speak up with their improvement ideas. People are the key to solutions, when leaders respond productively the whole system is improved and learnings reach those at the point of risk. In Shell we now call this Fair Event Handling. After a successful launch of the industry Life-Saving Rules on Safety Day, we recognise there is still a long learning journey ahead. We share the content of the paper as a means to encourage further sharing as we all strive to overcome dilemmas in what makes work difficult and together make compliance easier.
