Art & Science

At Great Lakes Ship­yard, design, engi­neer­ing and con­struc­tion are ver­ti­cal­ly inte­grat­ed to ensure that we deliv­er top-per­form­ing ves­sels in a time­ly and cost effi­cient man­ner, cus­tomized to your spec­i­fi­ca­tions. We take the best of both worlds, the art and design of Jensen Mar­itime Con­sul­tants, Inc. and the sci­ence behind pre­ci­sion engi­neer­ing, qual­i­ty crafts­man­ship and relent­less pur­suit for per­fec­tion. This bal­ance of art and sci­ence cre­at­ed the per­fect envi­ron­ment for the design and devel­op­ment of the “Tug­boat of the Year” – Great Lakes Ship­yard Jensen Series 92, a high­ly maneu­ver­able, durable and high-per­for­mance tug.

Engineering Excellence

Our team of engi­neers is pas­sion­ate about design­ing and devel­op­ing ves­sels that exceed your expec­ta­tions. Under­stand­ing what your needs and wants are is para­mount to us. This is why we meet with you and your team to under­stand your appli­ca­tion and deter­mine what your desired spec­i­fi­ca­tions are, so we can build a cus­tomized ves­sel specif­i­cal­ly for your ser­vice needs.

Thoughtful Design

How did we cre­ate the Tug­boat of the Year? By build­ing a trac­tor tug that is as agile and durable as it is pow­er­ful and tech­no­log­i­cal­ly advanced. By bench­mark­ing the world’s best work­boats and aim­ing even higher.

Every fea­ture of the Great Lakes Ship­yard Jensen Series 92 ASD Trac­tor Tug is thought­ful­ly designed to pro­vide your crew with best-in-class per­for­mance and capa­bil­i­ties, with added con­fi­dence and maneu­ver­abil­i­ty, to meet any ship assist or escort requirements.
