The work includes drilling, grouting, lifting and handling.

For the jacket installation, LDD is working with EMAS AMC to install four 48-inch outside diameter piles for each jacket.

Each pile will be 140m long, including a penetration of about 50m below the mud line.

The piles will be inserted into sockets drilled below the pile at each leg using 54-inch diameter underreaming drill bits.

LDD will use its LD2500 drill and associated downhole equipment and provide a range of grouting equipment, including stingers and reusable pile bungs.

The lifting and handling aspect of the project will be carried out by LDD's sister company LM Handling.
