SPT Offshore owns and operates 20 remotely controlled suction pumps for water depths from 10m up to 3,000m. These pumps are purposely built for the installation of single piles, suction pile clusters (SPCs), platform foundations or subsea structure foundations.

Next to that, SPT Offshore has a pool of 7 suction piles with a capacity of 120 – 250 mT that are available for rental when a temporary anchoring point is required. Furthermore, SPT has its own supporting equipment; control containers for the different pump skids, powered umbilical sheaves and umbilical winches, hydraulic power packs and autolock sheaves for pipeline pull-in.


SPT Offshore operates their own yard and test center in the Netherlands.

Supporting Equipment

Autolock Sheave
Hydraulic Power Pack

Powered Umbilical Sheaves

Powered umbilical sheaves are used for the umbilicals of the electric pump systems. The powered umbilical sheaves are placed on the sideshell of the installation vessel. This piece of equipment ascertains safe and smooth umbilical handling, eliminating the need of handling the umbilical by personnel, lowering HSE risks.

Power Packs

SPT Offshore owns and operated several hydraulic power packs, which can be used for various activities related to suction pile installation.

Control containers

All electrical pump systems are controlled and operated from the control container on the installation vessel’s deck. Data from all sensors in the suction pump skids are presented on screens present in this container. In case multiple suction pump skids are used on one structure, the levelness of the structure can be monitored and adjusted (if required) by adjusting the proportional suction flow in each suction pile.
