HTL were contacted by one of the world’s leading oil producers to solve a problem with a xmas tree which was no longer fit for purpose and required decommissioning. This particular xmas tree was over 15 years old and all valves and actuators had become seized over time.
The HTL Seasnake is a solution which eliminates the need for any divers being present when a Fastlock connection is released, removing the possibility of any subsea gas release becoming fatal, making these processes much safer.
The second application HTL have provided is known as the ‘Piggy Back’. The Piggy Back is a controlled diverless solution which uses hydraulics remotely to minimise operator involvement and ensures a controlled release of any volatile substances.
HTL’s ‘Manual Override’ has also been utilised during the decommissioning process. This is a hydraulically operated rotational tool designed to ensure controlled manipulation of critical valve systems. Again the focus here is on minimising operator involvement in dangerous subsea processes, ensuring that dangerous but necessary work is carried out safely.
It is this shared commitment to operator safety which led one of the world’s leading oil producers to work with HTL to implement these applications in order to improve their subsea operations. To date, all solutions have been a fantastic success and are pivotal to a continuous drive for a perfect safety record in subsea decommissioning processes.

Subsea decommissioning is an important and increasing consideration for the oil and gas industry, as ageing assets reach the end of their economically useful life, decommissioning projects are being planned and carried out.
The offshore decommissioning industry plays a major role in the planning process of the life of a well. Determining the most suitable strategy for decommissioning requires weighing up the differences between costs, safety, difficulty, environmental impact and various other contributing factors must be considered.
There are various kinds of subsea xmas trees which are designed and rated for various water depths, temperatures, pressures and expected flow. Whatever the application, the HTL Seasnake can be adapted accordingly; with HTL’s engineered to order service we can offer bespoke engineered products to design a solution that will meet your individual requirements.
Using bolting equipment in an area where there are high pressure systems has its dangers and when encountering this in a subsea environment, the safety hazards increase substantially.
The HTL Seasnake is a solution which eliminates the need for any divers being present when a Fastlock connection is released. This removes the possibility of any subsea gas release becoming fatal, making these processes much safer.
Using the HTL Seasnake, the HTL Low Profile Torque Wrenches fit over the male to female sockets and are clamped in place, removing the need of an operator when the loosening of the bolts is underway.
