L M Constructor

Wasn't sure what this was on the Me4rsey so referred to the internet.
"The flat-top barge LM Constructor is a general purpose vessel suitable for a wide range of inshore projects.  At 60m x 19m it is equipped with modern accommodation for up to 40 people.
With three successive seasons operating off the coast of Dounreay in Northern Scotland to carry out the clean up of an area of the seabed by recovering nuclear particles, the purpose designed tracked ROV complete with launch and recovery system capable of deploying the equipment in sea-states with significant wave height up to 2m has proved a highly successful combination.
In July 2014 LM Constructor completed the refurbishment of the Meols (Wirral) Outfall diffusers, for the client United Utilities.
