The project

From enquiry to lift

01 · Challenge

[The client’s problem in one line]

[What did Allseas need to remove, from what water depth, and what made it hard: the jacket’s weight and leg sizes, the weather window, the vessel’s lift system, the regulator? Why couldn’t a conventional approach do it?]

02 · Solution

Internal lifting tools that grip inside the jacket legs

[What we designed and delivered: the number of ILTs, their capacity and adjustable diameter, any bespoke changes, and how long from enquiry to delivery. Explain the connection in plain words for a project manager.]

03 · Testing

Proof-load tested in Morecambe

[What was proof-loaded, to what factor, on which rig, and who witnessed and certified it.]

04 · Deployment

[How the lift went offshore]

[Mobilisation, the lift itself, release at zero load, and the technicians we sent. Numbers beat adjectives: lifts completed, hours, days on site.]

As the lift starts, each ball rolls up its taper and wedges against the wall. More load means more grip.

How a Balltec connector grips: the load drives each ball up its taper.
