Marcon acted as the broker for buyers and Lee Felterman & Assoc. represented the seller.

Ocean Marine Services, Inc. operates OSVs servicing offshore oil and gas production platforms and assisting in backup spill operations in the challenging Cook Inlet, Alaska environment of minus 35 deg. Fahrenheit temperatures, sheet ice conditions, 30 ft tides and up-to 8 knot currents.

One desirable feature for vessels servicing the rigs in Cook Inlet is the low profile, "Gulf style" aft stacks on the Sabre as the OSV has to steam close alongside the rig heading into the current while transfering cargoes. The "Gulf" style stack is less likely to tangle with hoses or other gear hanging below the platform than higher "North Sea" style stacks located close behind the pilothouse.
