Abstract This paper outlines an approach for de-manning brownfield offshore production installations. It discusses how the latest advancements in rotating equipment, electrical & automation systems, and digitalization can be applied to reduce operating costs, lower breakeven prices, and extend the lifetime of existing/aging fields. The approach is value-rather than technology-driven and focuses on prioritizing investments based on return on investment (ROI) to enable low-manned operations as a stepping-stone towards unmanned installations. The paper discusses key facets of a holistic de-manning strategy, including: Remotely controlled production operations Predictive analytics to reduce unplanned downtime and extend mean time between overhauls (MTBO) Automated inspections Remote collaboration Unified data management Change management The concepts presented in the paper are derived from the authors’ company's work implementing digital solutions for customers in both onshore and offshore oil and gas, and power generation industries. It also draws on the results of an in-depth onshore field de-manning study that was conducted for a major Middle East national oil company (NOC).

Assigning correct ‘safety critical’ (SC) status for tags in offshore production and/or in a process facility is vital for an asset owner. It minimizes not only health, safety & environmental (HSE) challenges but also the wastage in terms of cost, time and effort of maintenance activities. Correct assignment of the SC status for a tag obviates the selection of a tag which does not deserve safety critical status and vice versa. A case study has been carried out to perform a re-evaluation and audit of the safety critical status of the tags which have already been assigned by two engineering contractors (ECs) in a floating production storage and offloading (FPSO) facility designed for offshore oil and gas (O&G) industry. However, the asset owner has discovered a gap between the results of aforementioned SC status assignments which have been carried out by the initial ECs. Hence, the results of initial two SC status assignments have been handed over to a third party engineering contractor for the purpose of re-evaluation and verification. This manuscript maps the work process attached to the reevaluation and verification. Finally, it presents the reasons discovered for the inconsistencies that caused the mismatch in the initial tag SC status assignments.

As onshore oil and gas deposits are becoming more difficult to locate, and as the world demands for energy continue to increase at an alarming rate, oil companies are channeling much of their exploration activities towards offshore operations, and in particular, towards operations centered off Canada's coast lines. Because of the environment, offshore drilling presents problems which are novel to the onshore-geared oil industry. J. M. Killey discusses in detail many of the considerations involved in drafting the offshore drilling contract, concentrating on problems such as the liability of the various parties; costs; scheduling; pollution; conflict of laws; etc. Similarly, he discusses service contracts (such as supply boat charters; towing services; helicopter services; etc.^ which are necessity to the operation of an offshore drilling rig. To complement his paper, the author has included number of appendices which list the various considerations lawyer must keep in mind when drafting contracts for offshore operations.
