## Abstract

A system for laying a pipeline from a floating vessel onto the ocean floor in relatively deep ocean water which provides pipe support means which can be disposed under and away from support shoulders on the pipeline and provides means to distribute the high stresses of pipe loading among members so as to not overstress any one member.

## Claims

### Claim 1

In a system for handling pipes having landing rings from a floating vessel having a mast and a working table
a travelling table with
an external shell supported by cables a first distance apart
internal shoulders a second distance apart less than said first distance,
a main body having support shoulders said second distance apart for engaging said internal shoulders of said travelling table,
said main body being moveable on said internal shoulders proximately perpendicular to the axis of said pipes.

### Claim 2 (depends on 1)

The invention of claim 1, further comprising such that when said main body is moved away from said pipes, a first landing shoulder is not positioned to support said landing rings.

### Claim 3 (depends on 2)

The invention of claim 2, further comprising that one or more cylinders are attached to said main body to move said main body toward or away from said pipes.

### Claim 4 (depends on 1)

The invention of claim 1, further comprising said main body which provides a first landing shoulder for supporting said pipes on said landing rings when said main body is adjacent said pipes.

### Claim 5 (depends on 4)

The invention of claim 4, further comprising a first door section which connects to one side of said main body and provides a second landing shoulder,
a second door section which connects to the other side of said main body and provides a third landing shoulder, and
a pin for connecting said first door to said second door when said first door and said second door are closed to a position adjacent to said pipes.

### Claim 6 (depends on 5)

The invention of claim 5, further comprising such that when said first and second doors are closed and pinned with said pin, said first, second, and third landing shoulders are positioned to support said landing rings.

### Claim 7 (depends on 6)

The invention of claim 6, further comprising such that when said pin is removed and said first door and said second door are opened, said second shoulder and said third shoulders are not positioned to support said landing rings.

### Claim 8 (depends on 7)

The invention of claim 7, further comprising such that when said main body is moved away from said pipes, said first landing shoulder is not positioned to support said landing ring.

### Claim 9 (depends on 8)

The invention of claim 8, further comprising that one or more cylinders are attached to said main body to move said main body toward or away from said pipes.
