Background

Purpose

Scope of work

Limitations

Oil spill response, including oil operation simulations, has not been part of the work, as it is covered by other TFOPP work measures. Measures relating to shuttle tankers and vessels sailing on the high seas are not part of the work as they are covered by other TFOPP work measures.

Terms and definitions

In this regard, capping and containment equipment is considered a risk reduction measure with regard to hydrocarbon emissions into the marine environment. Similarly, early detection equipment for leaks and spills is considered a risk reduction measure with regard to further releases of hydrocarbons into the marine environment.

Follow-up of this work

The report shows that extensive research and development initiatives have been ongoing for several decades related to increasing the safety of offshore oil activities in Arctic and cold climate regions. The project covers a wide area with the aim of presenting a comprehensive overview of ongoing and planned measures related to the prevention of oil pollution in the Arctic marine environment due to offshore oil activities.

Arctic and cold climate regions

For the purposes of this report, the areas described in ISO are considered to be most relevant to offshore petroleum activities in the Arctic. However, technology developed and R&D activities related to these areas may be of interest to Arctic offshore petroleum activities and are therefore included in this report.

Specific conditions for the Arctic regions

  • Daylight
  • Visibility
  • Temperature
  • Icing
  • Wind and wind chill
  • Precipitation and snow
  • Polar lows
  • Water depths
  • Waves
  • Ocean currents
  • Sea ice and icebergs
  • Seabed conditions
  • Distance

The temperature of sea water in the Arctic and in cold regions is low most of the year. Precipitation in the Arctic and cold regions falls as rain and snow, although the amount.

Stages in offshore petroleum exploration and development

The main concepts for Arctic exploration and development are then described, along with adverse events that may cause acute marine pollution from such development. This step is part of prioritizing which issues will be included in the project, see Figure 5.

Relevant exploration and development concepts

  • Fixed structures
  • Floating structures
  • Subsea structures
  • Extended reach wells from shore

This concept is applied for example at offshore Sakhalin in the Okhotsk Sea, in Newfoundland (Hebron and Hibernia) and the Pechora Sea, and was previously used as a drilling concept in the Beaufort Sea. Floating, production, storage and offloading (FPSO) or floating, storage and offloading (FSO) systems are typically ship/ship-shaped vessels and store crude oil in tanks located in the hull of the vessel.

Undesirable events

Each of these events can be linked to one or more of the main groups of concepts relevant to exploration and development in Arctic and cold climate regions described in the previous section. In this section, an overview of the main sources of relevant information for this project is presented.

Response from the baseline survey

The report attempts to provide a broad overview, covering the key areas within the scope of work. This is achieved through the approach taken, but due to the breadth of the issues examined, the report may not have managed to cover all existing, ongoing or planned initiatives.

The goal of the timeline was to identify research and development needs for oil and gas development in the Arctic and sub-Arctic regions. Technological challenges and state of knowledge: PSA published a report on technological challenges and state of knowledge to reduce the risk of adverse events causing acute marine pollution related to offshore oil activities in the Norwegian part of the Barents Sea (PSA, UiS and IRIS, 2010 ).

Metocean and ice conditions

Ocean Current Modeling: The Simula / KALKULO Research Laboratory conducts a project that examines the scientific and modern basis for ocean current modeling with the goal of. Reference information on the state of physical oceans and regional seas: The Copernicus Marine Environment Monitoring Service (CMEMS) provides regular and systematic reference information on the state of physical oceans and regional seas.

Technology for metocean data collection

Ice management

  • Ice forecasting, detection and monitoring
  • Station-keeping in ice
  • Physical ice management
  • Disconnection

One part of the PRNL ice management program (PRNL, 2014) focuses on station retention in sea ice. One part of the PRNL ice management program (PRNL, 2014) focuses on the towing of icebergs in sea ice.

Drilling technology, well integrity and well control

Drilling technology and well integrity

Mud weight control during drilling in the Arctic: In the Arctic, permafrost and sediments containing gas hydrates under the seabed present a technical difficulty in drilling. These can provide more robust wells, which will be a requirement in the sensitive Arctic.

Well control

The stop stack functioned properly at pressures that exceeded the highest expected pressures that Shell may encounter in the Arctic. Capacities of the stope stack and containment dome must meet requirements specific to the characteristics of the proposed well.

Pipelines and subsea structures

Pipeline and subsea structure integrity

According to Georghiou et al. 2015), future designs should look for a more complete model of the given scenario to reduce unnecessary conservatism. Shear data was collected from less than half of the area shown in the mosaic.

Pipeline integrity monitoring and leak detection

2015) presents the detectability and operating principles of fiber optic cable systems in the Arctic, including lessons learned from using them in previous projects. Furthermore, the paper covers operating principles and technology status of leak monitoring systems for Arctic pipelines.

Facility design

  • Ice loads
  • Ice model testing
  • Material selection
  • Winterization

The project will design protection methods and assess the need for other types of drilling units than those currently used in the Norwegian part of the Barents Sea. The ice model test shows that the concept is capable of operating in the tested ice conditions.

Loading and offloading

For periodic inspections or maintenance, the insulation blankets can be easily removed and replaced if necessary. Stamas Engineering Arctic Pads: Arctic pads are heated rubber mats that provide a durable, non-slip surface for arctic and harsh environments and can be used on stairs, platforms, landings, escape routes, assembly stations, ship and upper decks, oil rig floors etc.

Communication solutions

Communication in the High North and other remote areas (COINOR) The primary objective of the COINOR project is to minimize the knowledge gap about telecommunications in the High North, in order to provide sound recommendations on how to overcome the current lack of infrastructure and technological solutions lit ( Bekkedal and Fjørtoft, 2014. The MARENOR result will be a tool for predicting navigation and communication system performance in the High North.

Human resources and competence

Management

Oil spill detection

Much work is being done in the field of oil spill detection to develop remote sensing technologies to monitor oil under different conditions of ice and visibility. Oil Spill Detection and Management JIP (initiated 2014): The objective of the JIP is to improve oil spill management via communication infrastructure and management systems.

Development of new concepts for exploration and production activities

  • Mobile offshore drilling units (MODUs)
  • Drilling of exploration and production wells from land
  • Seabed drilling rigs
  • Subsea production systems
  • Floating production units
  • Support vessels for inspection and maintenance activities

The ice class is for a significantly extended drilling season for much of the Arctic - with an ice class of PC-4. Moss Maritime designs vessels with icebreaking and survivability capabilities to withstand the impacts of arctic extremes, such as Arctic environment drilling rigs, FPSO icebreakers, icebreakers, LNG icebreakers, gravity base barges (Moss Maritime, 2015).

The Center for Integrated Remote Sensing and Forecasting for Arctic Operations (CIRFA) project started in 2015 and will run for a maximum of eight years. The main objective of the center is to develop knowledge and technology for monitoring maritime conditions and. However, for various reasons, only the SALTO JIP was initiated. The SALTO JIP will provide a PC simulation tool for risk-based, probabilistic design to help industry prepare for the environmental conditions (wind, fog, ice, icing) in the Arctic and henceforth the operation of ships and offshore optimize structures.
