Obiettivo
To extend the use of existing high energy welding technology to a depth of
1,000 ft. It was also intended to develop the necessary support systems and to investigate the design of a sleeve with a double high energy capacity. This would be applicable to an all welded connection using a minimum of handling equipment.
No significant progress has been achieved.
The development of the project was submitted into 3 major work areas:
1. Welding technology
To establish the parameters for 2 pipe specifications and demonstrate by simulation testing the acceptability of the process at a depth of 1,000 ft sea water. A demonstration would be arranged with certifying authorities for a full-scale test to be performed remotely at a depth of 1,000 ft sea water.
2. Systems
The following aspects were studied:
- pipe sizing tool
- multi-size machining capability
- ultrasonic inspection system
- bag deployment monitoring
- corrosion inhibition
- remote detonation unit
- umbilicals and flush and dry sequencing unit.
3. Feasibility of a double welded sleeve
The following particular aspects were investigated:
- overall sleeve design to accommodate the various operational requirements
- seal design and arrangement
- charge design
- corrosion problem
- handling problems.
