The TENSA Dynamic Motion System (DMS) is an extremely powerful multi-function system using inertial and GPS sensors to provide decision support information and data for offshore marine operations. It allows cranes to lift larger loads and with higher safety margins.
The Tensa DLR is used on offshore cranes to drastically reduce the dynamic loads associated with lifts from moving vessels. The DLR will typically increase the crane capacity by between 20% and 40% for dynamic lifts. The DLR can also be used in applications such as pile driving where it will absorb shock loading if the pile drops when driving.
Tensa provides a range of in-line heave compensation equipment that is designed to be used with existing cranes or winches. Systems include cylinder type that are hung between the hook and the load as well as deck mounted systems that are used between the winch and the overboarding sheave. Tensa also provides subsea passive heave compensators that may be used when lowering heavy subsea equipment to the seabed.
Tensa provides a complete range of conductor tensioning systems for jackup drilling rigs and for tender assist rigs. We offer both push type systems designed to be located on the conductor deck and pull type systems that are attached to the underside of the drill floor.
We also make a range of accessories to suit Tensa and other brands of conductor tensioner systems.
Tensa provides a range of gripper type conductor clamps that are designed to work with both Tensa and other brands of conductor tensioning systems. We also make speciality clamps needed for pipelay and offshore construction operations.
Tensa also offers a range of specialty lifting tools for onshore, offshore and subsea construction.
Why to use a gangway instead of a personnel basket
This video illustrates one reason why a gangway should be used instead of a personnel basket when transferring from ship to ship.
Why to use a gangway instead of direct landing a boat under a ladder
In this video the protruding nose of the vessel gets caught under the ladder. Even using a small boat pushing against a buffer rail has its dangers.
This is why you don’t want to be under a load while a crane is doing a lift!
Tensa is currently developing ROBORIGGER – a suite of products designed to allow the dangerous operations of orienting and landing lifted loads without the need for people to be in the vicinity of the load.
How handy would it be to have a device with a camera just above the load?
This is the crane driver’s view of the load and the people on the boat who must disconnect the load. Tensa’s ROBORIGGER is a device designed to allow the dangerous operations of orienting and landing lifted loads without the need for people to be in the vicinity of the load.
Would you like this to be your job?
This video highlights where ROBORIGGER could play a vital role in the intricate task of wind turbine blade installation. ROBORIGGER would allow the blade to be oriented and released without the need for personnel to be in the vicinity of the load.
Windy conditions cause cladding panel to spin uncontrollably
Tensa’s ROBORIGGER would have helped making this lifting operation safer for the personnel and also limit the risk of damage to the panel itself.
