SHALLOW WATER TRENCHING SUPPORT PONTOON BARGE - SPIDER 1
The shallow water pontoon is used for Shore Approach Trenching on projects where the main support vessel is limited by its operational draft, and is unable to come close enough to shore. It is specially designed to be lifted offshore in fully loaded condition (65T).
The whole spread can be easily dismantled and containerised for convenient shipping worldwide.
