The October 4 2018 COPRI Houston Conference lecture Breakwater Caisson Design was presented a few days before the first Nador Caisson was loaded out in Morocco.
This video illustrates a success story.  The loading out the 3,000 tonne caisson (that had been slipformed on land) is shown onto a semi-submersible barge.  The barge is towed to relatively deep water and ballasted down, until the caisson can be floated...

The full lecture can be viewed at CAISSON DESIGN VERIFICATION.  This lecture was presented at the ASCE COPRI 2018 Houston Chapter Conference.
A cross section through the main breakwater is shown below:
Wave forces and safety factors against sliding and overturning are computed with Excel and shown in the Excel chart below:...

Catastrophic crane boom backwards collapse caused by crane boom recoil from sudden loss of load can be avoided, even if crane boom stops are ineffective, or not fitted.  The video below explains the simple calculations needed.  These calculations should...

A presentation made to the SUT Offshore Site Investigation and Geotechnics Committee(OSIG) and Offshore Renewables Committee (OR) of SUT-US on August 30, 2018 is shown below.
Falling renewable power costs signal a real paradigm shift in the competitiveness of different power generation options. This includes cheaper electricity from renewables as a whole, as well as the very low costs now being attained from the best solar...
