Numerous drivers for new and improved technologies…

� Offshore oil & gas moving to harsher environments: deep and ultra deep waters, high pressure high temperature reservoirs, CO2 and H2S rich well streams.

� Massive use of subsea technology requiring new installation and intervention technology and vessels

� Increased use of ROV’s and AUV’s

� Standard setting and technology qualification for new technology and use of existing technology beyond original boundaries

Numerous drivers for new and improved technologies…

� Developments in the Arctic - Smaller and thinner ice cap due to global

warming- Exploitation of fisheries, oil and gas, and

rare-earth minerals- Significant reduction of the distance

between Asia and Europe- Increased volume of tourist traffic

� Offshore wind

� Floating LNG

� International requirements to reduce local emissions to air

� High fuel prices requiring more energy efficient operation

Categories relevant fuel saving measures – plenty of room for technology development

Improving operationalefficiency

Reducing hullresistance

Improving power-plant efficiency

Improving propulsionefficiency

Energy efficiency


One example of from idea-to-concept: APL13100 TEU

� Optimized solutions combined with new technology transporting more cargo while using less fuel

� Developed for flexible operation with respect to trades and markets

� 10 new 13,800 TEU container ships

� Optimized for flexible operation - speed and draft range

� Annual operational saving- 3 mill USD per ship- 30 mill USD all ships

LNG

� Currently cheap energy source with vast reserves

� Best environmental performance for ship propulsion

� More tank volume cf conventional ship fuels

HFO Distillate Fuels LPG GTL

CNG Biogas Hydrogen Battery Nuclear

� Available + established distribution network

� With proper exhaust cleaning systems, it will comply with planned env requirements

� Might not meet future env requirements

� Minimal changes to the ships engine design and fuel supply systems

� Analysts expect fairly steep prices

� Uncertainty (refineries’ capacity to meet demand for these fuels)

� Liquid at higher temperatures than LNG

� More expensive + available in smaller volumes

� Severe safety concerns (different flammability and dispersion cf LNG)

� Transport mode for natural gas, competing with LNG

� Liquid at atmospheric temperature (easier to transport and distribute)

� GTL process consumes a large share of energy (~ 40%)

� Easier to distribute to the ships than LNG (extracted from existing gas distribution grids)

� Twice tank volume as LNG to offer the same sailing distance

� Politicians say that biogas might become available in the future

� Shipping industry doubts that biogas will penetrate any significant share of shipping.

� Identical systems to LNG

� Potential energy carrier

� Production in land-based plants and then utilised in fuel cells / combustion engines in ships

� Challenges: efficient production + volume occupied (~ 6 times the space of LNG)

� Battery is another way of carrying energy from land-based plants to ship (in the form of electricity)

� Battery technology and lifecycle efficiency are key challenges

� Wild card in this list of future fuels

� Potential is tremendous, and the environmental benefits are strong (proper waste handling)

� Safety concerns and perceived risk

Top ten future fuels for shipping

Alternative fuels


Hybrid propulsion: The Prius of the seas

Deep water lifting

13

� Deep water field developments demand high focus on safety both in the installation phase and throughout the lifetime of the field. This focus will increase when:

- going into deeper and ultra deep waters - lifting larger/heavier and more complex/expensive structures - having impact risk with critical subsea infrastructure - struggling against rough weather conditions (incl. arctic/ice)


Barents Sea Challenges

� Low temperatures

� Sea ice

� Marine icing

� Visibility

� Remoteness

� Vulnerable Environment

� Uncertain metocean data (e.g. polar lows)

Collaboration Areas


Topic 1 – Ship performance in waves

� Ship resistance, propulsion and manoeuvring in waves

� This is a DNV focus area within hydrodynamics and advanced simulations

� There are currently two main application areas- Ship speed and manoeuvring in adverse conditions. - Improve ship designs to reduce fuel consumption

17


Topic 2 – Safer and smarter ships by sensors and control

Safe introduction of

� New hull designs and complex machinery systems for increased fuel efficiency

� Advanced simulation tools for efficient design and continuous monitoring

� Autonomous fault-detection and control

� Ubiquitous sensors collecting high quality data for performance and condition monitoring, onboard and onshore

18


Topic 3 – Dynamic positioning (DP)

� Current focus is on so-called “Green” DP- Improve the system design with regards to safety / reliability as well as energy consumption

and cost

� Further developments are needed to get practical methods for evaluating actual DP performance

� DNV is initiating a DP joint industry project , which includes DP benchmarking for actual operating conditions. This JIP would benefit from a close collaboration with AMOS

19


Other collaboration areas

� Environmental monitoring services- Biology during field development and life

cycle- Distribution of oil spill- Ice distribution and characteristics

Today: Sampling Future: More continuous monitoring

� Renewable energy- Safe and optimal

design of wind turbines

- Connection to grid

� Subsea Factory- Leakage- Reliable

production
