Northstar Marine Inc., Clermont, N.J., has added two offshore supply vessels to its fleet — the 240' Commander and the 185' Independence. The addition of the OSVs enables Northstar to further support long-duration projects in the offshore waters of the U.S. East Coast, the Bahamas and Caribbean, the company said.

Both vessels can accommodate a wide variety of services. The Commander carries deck cargo of up to 1,300 tons and the Independence carries up to 400 tons. Both vessels are equipped with DP-2 dynamic positioning systems for precise stationkeeping in high winds and strong seas. This capability is critical to many scientific, construction and salvage projects. Northstar is the only marine services company in the Northeast region of the U.S. to offer DP-2-equipped vessels and an OSV as large as the Commander, company officials said.
