General Dynamics Electric Boat Bay 4

165 Dillabur Ave, North Kingstown, RI, 02852

Massive High-precision Assembly

This 150,000 sq ft bay used to construct submarine deck modules for the Navy’s Virginia class nuclear submarines is a massive steel structure. It includes the largest single crane structural steel pick – Weighing 268 tons – in RI history. This giant steel puzzle was assembled on the floor before being hoisted up into position.

The steel structure fabrication and erection represented an extremely  high precision challenge. This impressive structure had to fit between two existing buildings with a clearance of no more than a foot.

The steel structure supports heavy-duty lifting equipment with a combined capability of 150 tons.

Time Engineering to accomodate change

Our Time Engineering team altered work flow to accommodate mechanical and electrical evolving requirements while having to comply with a very aggressive schedule.

Due to the inherent complexity of the project our Time Smart Manufacturing proved very valuable in completing fabrication as scheduled. Our manufacturing agility again delivered.

The quality of Canatal’s production greatly eliminated rework at job site. Erection team ingenuity and expertise were very instrumental to the success of the project.

Team Canatal accommodated this fast-track project.
