Table 16 Sub-sea technology design and performance
RTD TOPICS/ OBJECTIVES Category
1. To enhance minimum intervention, diverless technology coupled with TE + CR
intelligent condition monitoring especially for deepwater and/or remotely
located equipment.
(Deepest diver intervention presently around 450m but with very short work
window. )
2. To develop technology with reduced reliance on moving/rotating parts, to TE + CR
reduce reliance on umbilicals, to increase reliability of electrically powered
equipment and to shift to hydraulically powered machines wherever possible.
3. To develop local, including renewable, power sources for offshore operations TE + CR
in remote locations, especially in low gas to oil ratio fields:
- options are for using wind, waves, ocean currents or nuclear energy.
4. To facilitate the re-use of sub-sea equipment (e.g. trees, manifolds, control CR
systems):
- will require, in part, increased confidence in prediction of corrosion over
a service life of say 30 years and several locations with unknown reservoir
fluids. Otherwise engineering to address uncertainties may lead to initial
capital equipment costs beyond what first use would require. Also requires
designs which are easily retrievable, are interchangeable and are capable of
dealing with unknown reservoir fluids in later service.
5. To enhance/upgrade capability of sub-sea equipment for HP/HT service, TE
including:
- sub-sea well head equipment for HP/HT service (350�C and > 15,000 psi).
(Asset focus of the above topics: all field developments and production, with
specific topics focused on deepwater, remote, economically marginal and
HP/HT conditions)
TE- technology enhancement. CR- cost reduction. E- enabling.
