## Abstract

A method and system for completing a well below the bottom of a body of water includes assembling a completion string at a location away from a location of the wellbore, moving the assembled completion string to the location of the wellbore and inserting the assembled completion string into the wellbore.

## Claims

### Claim 1

A method for completing and re-completing a well below the bottom of a body of water, comprising:
assembling a well completion string at a location away from a location of the wellbore to form an assembled well completion string;
moving the assembled well completion string to the location of the wellbore; and
inserting the assembled well completion string into the wellbore.

### Claim 2 (depends on 1)

The method of claim 1 wherein the assembling is performed substantially horizontally.

### Claim 3 (depends on 2)

The method of claim 2 wherein the moving is performed by suspending in the water the assembled well completion string from at least one vessel.

### Claim 4 (depends on 1)

The method of claim 1 wherein the assembling is performed by moving one end of the well completion string into the body of water by towing from a vessel while segments of the well completion string are coupled to the other end of the string.

### Claim 5 (depends on 1)

The method of claim 1 wherein the moving comprises suspending the assembled well completion string from a vessel disposed proximate each end of the well completion string.

### Claim 6 (depends on 1)

The method of claim 1 wherein a well completion string is removed from a well and then fully or partially disassembled horizontally at a location away from the wellbore

### Claim 7 (depends on 1)

The method of claim 1 wherein the well completion string is a drill-string.

### Claim 8

A method for wellbore intervention, comprising:
lifting a pipe string from within a wellbore wherein the wellbore is situated by winching one end of the pipe string thereof toward a first vessel on the surface of the water;
moving the vessel away from a location of the wellbore;
lifting the other end of the pipe string toward the surface of the water by winching the other end toward a second vessel on the surface of the water; and
moving the first and the second vessels away from the location of the wellbore.

### Claim 9 (depends on 8)

The method of claim 8 further comprising moving the pipe string to a location away from the location of the wellbore and performing at least one repair operation on the pipe string.

### Claim 10

A safety and guiding assembly comprising:
a substantially cylindrical body having a proximate end, a distal end, and an outer circumference;
an upper guide funnel, the upper guide funnel mechanically connected to the proximate end of the substantially cylindrical body and adapted to receive a well completion assembly; and
a connector, the connector mechanically connected to the distal end of the substantially cylindrical body and adapted to fasten the substantially cylindrical body to a BOP.

### Claim 11 (depends on 10)

The assembly of claim 10 further comprising a buoyancy tank, the buoyancy tank secured to the outer circumference of the substantially cylindrical body.

### Claim 12 (depends on 10)

The assembly of claim 10 further comprising a pipe grabber, the pipe grabber disposed on the outer circumference of the substantially cylindrical body.

### Claim 13 (depends on 10)

The assembly of claim 10 further comprising a control umbilical, the control umbilical in mechanical connection with the substantially cylindrical body.

### Claim 14 (depends on 13)

The assembly of claim 13 further comprising a camera, the camera in electrical connection with the control umbilical.

### Claim 15 (depends on 14)

The assembly of claim 14 further comprising a movable arm, the arm in mechanical connection with the camera and in mechanical connection with the substantially cylindrical body.
