WE CLAIM: 

1. A pumpskid for use in installing and removing 
suction anchors from the seafloor comprising: 

a frame; 

a pump mounted on the frame and having an inlet 
and an outlet; 

a male connector mounted on the frame and adapted 
for engagement with a suction port on the suction anchor; 

latching means for securing the male connector on 
the pumpskid in engagement with the suction port on the 
suction anchor and thereby securing the pumpskid to the 
suction anchor; 

piping means connected in fluid communication 
between the inlet and the outlet of the pump and the male 
connector and including a port open to the surrounding sea; 
and 

valve means mounted in the piping means for 
selective actuation to cause water flow either into the 
pump from the^seaQand hence from the pump through the male 
connector into the suction anchor or outwardly from the 
suction anchor through the male connector and through the 
pump and hence into the^sea . Q

2 . The pumpskid according to Claim 1 further 
including a hydraulic motor mounted on the frame for 
driving the pump. 

3 . JThe pumpskid according to Claim 1 further 
including^*! O-ring extending around the periphery of the 
male connector for engagement with the suction port to form 
a water-tight seal. 

4 . The pumpskid according to Claim 1 wherein the 
latching means comprises a plurality of latching. pi**s and 
a plurality of hydraulic actuators each individual - to ono 
o € ther ^tfe^M^g^piaG* for selective actuation to extend the 
la^6fj^^^fr^s^n^ engagement with the suction port thereby 
securing the male connector in engagement therewith and for 

^ge^^c ^i o n t to disengage the male connector from the 
suction port .

5 . The pumpskid according to Claim 1 wherein the 
piping means includes a first portion extending in fluid 
Q^y^ communication between the inlet and^putlet of the pump and 

having the port open to the surrounding sea included 
5 therein, and a second portion connected in fluid 

communication between the infet^p^ the outlet of the pump 
and having the male connector included therein; 

wherein the valve means include a first valve 
mounted in the first portion of the piping means for 
10 selective actuation to connect the port in fluid 

communication with the inlet of the pump, a second valve 
included in the first portion of the piping means for 
selective actuation to connect the port in fluid 
communication with the outlet of the pump, a third valve 
15 included in the second portion of the piping means for 

selective actuation to connect the male connector in fluid 
communication with the inlet of the pump, and a fourth 
valve included in the second portion of the piping means 
for selective actuation to connect the male connector in 
20 fluid communication with the outlet of the pump; and 

further including linkage means for opening the first 
valve when the second valve is closed, and vice versa, and 
for opening the third valve when the fourth valve is 
closed, and vice versa.

6. A pumpskid for use in installation removing 
suction anchors from the sea floor comprising: 

a frame; 

a pump mounted on the frame and having' an inlet 
and an outlet; 

a hydraulic motor mounted on the frame for 
driving the pump; 

a male connector mounted on the frame and adapted 
for engagement with a suction port on the suction anchor; 

an O-ring extending around the periphery of the 
male connector for engagement with the suction port to 
effect a water-tight seal therebetween; 

a plurality of latching pins slidably mounted on 

the frame; 

a plurality of hydraulic actuators mounted on the 
frame for selectively actuating the latching pins to engage 
the suction^jpe*?t\ on the suction p©^t thereby securing the 
pumpskid skid in engagement with suction anchor and for 
retracting the latching pins to permit disengagement of the 
male connector from the suction port on the suction anchor 
thereby releasing /£b«- connection between the pumpskid and 
the suction anchor; 

piping means including a first portion connected in 
fluid communication between the inlet and the outlet of the 
pump and including a port open to the surrounding sea and

a second portion connected in fluid communication between 
the inlet and the outlet of the pump and m extending to and 
j ^t rom H vf n u mJle- connection ^ 

valve means including a first valve included in the 
first portion of the piping means for selective actuation 
to connect the port in fluid communication with the inlet 
of the pump, a second valve included in the first portion 
of the piping mens for selective actuation to connect the 
port in fluid communication with the outlet of the pump, a 
third valve included in the second portion of the piping 
means for selective actuation to connect the male connector 
in fluid communication with^inlet of the pump, and a fourth 
valve included in the second portion of the piping means 
for selective actuation to connect the male connector in 
fluid communication with the inlet of the pump; and 

linkage means connected between the first valve and 
the second valve and between the third valve and the fourth 

valve for opening the first valve when second valve is
